Question 1
An architect is holding a design workshop with a customer for a new solution. The customer states
that the new solution needs to provide the following capabilities:
Automated deployment and lifecycle management of the vSphere platform
Self-Service deployment of virtual machines and other objects from a central catalog
Monitoring, logging and analytic tooling to provide visibility and troubleshooting of the whole
solution
Support deployment via infrastructure-as-code methods for the additional management components
The customer also requests that the solution be as cost-effective as possible while still delivering a
fast time to value for the organization.
Which design approach should the architect recommend to meet these requirements?
- A. Use VMware Validated Designs for the vSphere solution and VMware Validated Solutions for the additional components
- B. Use VMware Cloud Foundation for the vSphere solution and VMware Validated Solutions for the additional components
- C. Use VMware Cloud Foundation for the vSphere solution and a custom design for the additional components
- D. Use a custom design for the vSphere solution and VMware Validated Solutions for the additional components
Answer:
B
Explanation:
The customer has outlined the following requirements:
Automated deployment and lifecycle management of the vSphere platform: This requires a solution
that provides automated provisioning, management, and updates. VMware Cloud Foundation (VCF)
is an integrated platform that provides automation for the lifecycle of the vSphere platform,
including updates and patch management.
Self-Service deployment of virtual machines and other objects from a central catalog: VMware Cloud
Foundation includes tools like vRealize Automation (part of VCF) that enable self-service provisioning
of virtual machines and other resources. Additionally, VCF provides centralized management for
provisioning and orchestration.
Monitoring, logging, and analytic tooling for visibility and troubleshooting: VMware Cloud
Foundation integrates with vRealize Operations and vRealize Log Insight, which provides visibility,
monitoring, and logging capabilities for the entire solution. These tools help in analytics and
troubleshooting across the entire infrastructure.
Support deployment via infrastructure-as-code methods for additional management components:
VMware Validated Solutions (such as vRealize Automation or vRealize Orchestrator) provide
infrastructure-as-code capabilities, ensuring that the solution can be deployed in a consistent,
repeatable manner, automating deployments of not just vSphere but also additional management
components.
Cost-effectiveness with a fast time to value: VMware Cloud Foundation offers an integrated solution
that is pre-configured and validated, which speeds up deployment and reduces operational
complexity. By using VMware Validated Solutions for additional management components, the
customer can leverage existing, tested solutions that are optimized for use with VCF, ensuring cost-
effectiveness while meeting requirements.
Question 2
An architect will be updating an existing vSphere data center design.
The following information has been provided:
The new design must carry over existing VLANs for workloads.
The networking for storage must not share the data path with workload traffic.
The new design must be able to add additional VLANS.
The new design must reduce management overhead.
The new replacement servers have two 100 GB network cards.
Which design will meet the requirements for existing workload networks and allow scaling of
additional networks?
- B. One vSphere standard switch (VSS) configuration Workload and storage traffic on separate uplinks
- C. Two vSphere distributed switches (VDS) Each VDS uses one uplink as active and the other uplink as passive Existing and new workload traffic on one VDS and storage traffic on the other VDS
- D. One vSphere distributed switch (VDS) configuration The VDS uses aggregated uplinks Workload and storage traffic on the aggregated uplinks
Answer:
D
Explanation:
The customer's requirements include the following:
Carry over existing VLANs for workloads: This can be easily achieved with a vSphere distributed
switch (VDS), as it supports the configuration of VLANs and ensures that they can be applied to
multiple ESXi hosts across the data center.
Networking for storage must not share the data path with workload traffic: By using aggregated
uplinks in the VDS configuration, the architect can easily separate workload traffic and storage traffic
by using different uplinks or VLANs. Aggregated uplinks ensure that there is sufficient bandwidth for
both workloads and storage, while keeping them logically separated in terms of traffic management.
Add additional VLANs: A VDS supports the dynamic addition of VLANs. New VLANs can be added and
managed centrally, reducing the complexity and management overhead when scaling the network.
Reduce management overhead: The use of a single VDS significantly reduces management
complexity compared to managing multiple vSphere standard switches (VSS). With VDS, network
configuration and management are centralized and simplified across all ESXi hosts.
Given that the new replacement servers have two 100 GB network cards, the aggregated uplinks in a
VDS configuration will provide the required network capacity while ensuring that traffic is properly
segmented and scalable.
Question 3
What is an example of an availability design quality?
- A. A vSphere cluster is configured to support an N + 1 level of redundancy.
- B. A vSphere cluster is configured to support a maximum tolerated downtime of one hour.
- C. A vSphere cluster is configured to stage patches on ESXi hosts before applying them.
- D. A vSphere cluster is configured to use a dedicated network adapter for vMotion traffic.
Answer:
A
Explanation:
Availability design quality refers to the capacity of a system or infrastructure to remain operational,
minimizing downtime, and ensuring continuous service delivery, especially in the event of a failure.
The concept of N + 1 redundancy ensures that if one component fails (such as a host or a power
supply), there is always an additional, spare component available to take over the workload,
maintaining the system's availability.
N + 1 redundancy in a vSphere cluster means that the cluster has enough resources to tolerate the
failure of one host without affecting the availability of the workloads. This setup provides high
availability and resilience in the event of a host failure.
Question 4
During a workshop for a design project, the following information is shared:
Develop and maintain strong relationships with key stakeholders and partners to promote
collaboration.
Maintain high standards of quality and professionalism in all aspects of the project.
Build a strong foundation for future projects, including cloud infrastructures.
Ensure project timelines and milestones are met by effectively managing resources and priorities.
Which of these would be classified as a business outcome of the project?
- A. Build a strong foundation for future projects, including cloud infrastructures.
- B. Ensure project timelines and milestones are met by effectively managing resources and priorities.
- C. Maintain high standards of quality and professionalism in all aspects of the project.
- D. iDevelop and maintain strong relationships with key stakeholders and partners to promote collaboration.
Answer:
A
Explanation:
A business outcome refers to a result or impact that directly contributes to the strategic goals of the
organization, typically focusing on long-term objectives or future benefits. In this case, building a
strong foundation for future projects, including cloud infrastructures, aligns with the business goal of
positioning the organization for future success and scalability. This outcome is about preparing the
organization for the future, which is a key business-driven result.
Question 5
An architect is documenting the design for a new multi-site vSphere solution. The customer has
informed the architect that the workloads hosted on the solution are managed by application teams,
who must perform a number of steps to return the application to service following a failover of the
workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The
customer has provided the architect with the following information about the workloads:
Critical workloads have a WRT of 12 hours
Production workloads have a WRT of 24 hours
Development workloads have a WRT of 24 hours
All workloads have an RPO of 4 hours
Critical workloads have an RTO of 1 hour
Production workloads have an RTO of 12 hours
Development workloads have an RTO of 24 hours
The customer has also confirmed that the Disaster Recovery solution will not begin the recovery of
the development workloads until all critical and production workloads have been recovered at the
secondary site.
What would the architect document as the maximum tolerable downtime (MTD) for each type of
workload in the design?
- A. The different processor architectures across both sites will remediate against a shared vSphere Lifecycle Manager baseline.
- B. The different processor architectures will be located in the same cluster to support vSphere Lifecycle Manager image-based remediation.
- C. The different processor architecture within a single site will remediate against a single vSphere Lifecycle Manager image.
- D. The different processor architectures across both sites will remediate against a single vSphere Lifecycle Manager image.
Answer:
C
Explanation:
vSphere Lifecycle Manager (vLCM) is used to manage ESXi host configurations and software versions
in a consistent and streamlined manner. In this case, the architect needs to account for the
heterogeneous hardware across two sites (Intel and AMD-based servers).
Since Intel and AMD processors are incompatible for remediation with a single vSphere Lifecycle
Manager image, the different processor architectures should be grouped by site (not across sites).
Within each site, vLCM can manage a single image per processor architecture, ensuring that each
site’s hosts with compatible processors are remediated consistently. Intel-based servers will be
managed with one image and AMD-based servers with another image, but they can be managed in
separate sites.
This approach avoids the issue where heterogeneous hardware with different processor types would
need separate images. By keeping them within the same site, the architecture simplifies the lifecycle
management and meets the requirement for minimizing clusters and ensuring service availability
during upgrades.
Question 6
An architect is responsible for the lifecycle management design for a brownfield vSphere-based
solution.
The following information has been provided during initial meetings around the new solution:
Existing heterogeneous server hardware will be used to provide the hosting platform.
The available hardware is:
- 10 servers that contain 2 x 20-Core Intel Xeon processors and 512 GB RAM from Vendor A
- 10 servers that contain 2 x 24-Core Intel Xeon processors and 768 GB RAM from Vendor A
- 20 servers that contain 2 x 16-Core AMD EPYC processors and 512 GB RAM from Vendor B
- 10 servers that contain 1 x 24-Core AMD EPYC processors and 256 GB RAM from Vendor B
All of the hardware is currently listed on the VMware Hardware Compatibility List (HCL).
All existing server hardware has 36 months vendor support remaining.
The requirements from the customer are:
REQ001 - The solution must support the hosting of 5,000 workloads spread across two physical sites.
REQ002 - The solution should minimize the number of clusters.
REQ003 - The solution must ensure that there is no impact to service when completing upgrades.
Given the resource requirements needed for the solution, the architect has calculated that all of the
existing servers will be required to provide sufficient resources for the new environment. The Intel-
based (Vendor A) servers will be deployed to the primary site and both the Intel-based and AMD-
based servers (Vendor B) will be deployed to the secondary site.
Which assumption should the architect make to support the lifecycle management of vSphere 8?
- A. The different processor architectures across both sites will remediate against a shared vSphere Lifecycle Manager baseline.
- B. The different processor architectures will be located in the same cluster to support vSphere Lifecycle Manager image-based remediation.
- C. The different processor architecture within a single site will remediate against a single vSphere Lifecycle Manager image.
- D. The different processor architectures across both sites will remediate against a single vSphere Lifecycle Manager image.
Answer:
C
Explanation:
vSphere Lifecycle Manager (vLCM) is used to manage ESXi host configurations and software versions
in a consistent and streamlined manner. In this case, the architect needs to account for the
heterogeneous hardware across two sites (Intel and AMD-based servers).
Since Intel and AMD processors are incompatible for remediation with a single vSphere Lifecycle
Manager image, the different processor architectures should be grouped by site (not across sites).
Within each site, vLCM can manage a single image per processor architecture, ensuring that each
site’s hosts with compatible processors are remediated consistently. Intel-based servers will be
managed with one image and AMD-based servers with another image, but they can be managed in
separate sites.
This approach avoids the issue where heterogeneous hardware with different processor types would
need separate images. By keeping them within the same site, the architecture simplifies the lifecycle
management and meets the requirement for minimizing clusters and ensuring service availability
during upgrades.
Question 7
An architect is documenting the design for a new multi-site vSphere solution. The customer has
informed the architect that the workloads hosted on the solution are managed by application teams,
who must perform a number of steps to return the application to service following a failover of the
workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The
customer has provided the architect with the following information about the workloads:
Critical workloads have a WRT of 12 hours
Production workloads have a WRT of 24 hours
Development workloads have a WRT of 24 hours
All workloads have an RPO of 4 hours
Critical workloads have an RTO of 1 hour
Production workloads have an RTO of 12 hours
Development workloads have an RTO of 24 hours
The customer has also confirmed that the Disaster Recovery solution will not begin the recovery of
the development workloads until all critical and production workloads have been recovered at the
secondary site.
What would the architect document as the maximum tolerable downtime (MTD) for each type of
workload in the design?
A.
Critical Workloads: 13 hours
Production Workloads: 36 hours
Development Workloads: 48 hours
B.
Critical Workloads: 13 hours
Production Workloads: 36 hours
Development Workloads: 60 hours
C.
Critical Workloads: 12 hours
Production Workloads: 24 hours
Development Workloads: 24 hours
D.
Critical Workloads: 16 hours
Production Workloads: 28 hours
Development Workloads: 28 hours
Answer:
A
Explanation:
The Maximum Tolerable Downtime (MTD) is the maximum time that an application or system can be
unavailable before it negatively impacts the business. The MTD is calculated by adding the Recovery
Time Objective (RTO) to the Work Recovery Time (WRT). Here’s how it applies to each workload
type:
Critical Workloads:
- RTO: 1 hour (time to restore the system to a usable state after failure).
- WRT: 12 hours (the time to get the application fully back to service).
- MTD = RTO + WRT = 1 hour + 12 hours = 13 hours.
Production Workloads:
- RTO: 12 hours (time to restore the system to a usable state after failure).
- WRT: 24 hours (time to get the application fully back to service).
- MTD = RTO + WRT = 12 hours + 24 hours = 36 hours.
Development Workloads:
- RTO: 24 hours (time to restore the system to a usable state after failure).
- WRT: 24 hours (time to get the application fully back to service).
- MTD = RTO + WRT = 24 hours + 24 hours = 48 hours.
Question 8
An architect is designing a vSphere-based application hosting solution in a brownfield site.
The following information has been provided during the requirements gathering workshop:
The solution should support 5,000 compute workloads across two physical sites.
The CFO has approved budget for the purchase of new server and network hardware only.
The existing storage array is currently Fibre Channel connected with 2 x 8 Gbps interfaces to a
dedicated Storage Area Network (SAN) fabric.
The existing storage array does not support integration with vSphere API for Storage Awareness.
The existing storage array can be configured to support NFS storage.
The existing vSphere administration team will responsible for operational management of the new
solution.
Which storage technology should the architect recommend based on these requirements?
- A. vSphere Virtual Volumes (vVols)
- B. iSCSI
- C. Fibre Channel
- D. VMware vSAN
Answer:
B
Explanation:
Based on the requirements provided, the architect should recommend iSCSI for the following
reasons:
Existing Storage Array: The existing storage array does not support integration with vSphere API for
Storage Awareness (VASA), which is required for vVols and VMware vSAN. This means that vVols and
vSAN cannot be used without significant upgrades or changes to the storage infrastructure.
Existing Fibre Channel Connectivity: The storage array has Fibre Channel connectivity, but it is limited
to 2 x 8 Gbps interfaces and is not compatible with advanced features required by modern solutions
like vVols. In addition, Fibre Channel is traditionally complex to manage and requires specialized
knowledge, which may not align with the existing vSphere administration team's expertise.
Support for NFS Storage: The storage array can be configured to support NFS storage, which is an
efficient, simpler-to-manage option compared to traditional Fibre Channel or iSCSI. Since iSCSI is also
IP-based, it aligns well with the existing vSphere environment.
Scalability and Simplicity: iSCSI allows for easy integration with vSphere and is a highly scalable
option for expanding storage across two sites, which meets the requirement of 5,000 compute
workloads across two physical sites. It is also easier to manage compared to Fibre Channel and vVols.
Question 9
An architect is working on a security design for a shared storage environment. The storage array
provides connectivity by the NFS protocol.
Which two design decisions could the architect include for this solution? (Choose two.)
- A. Create a dedicated storage network
- B. Create a dedicated VLAN
- C. Create a challenge handshake authentication protocol (CHAP) password to prevent unauthorized access
- D. Create dedicated volumes for sensitive data
- E. Create a dedicated Fibre Channel network
Answer:
A, B
Explanation:
Create a dedicated storage network:
Creating a dedicated storage network ensures that storage traffic is isolated from general network
traffic, improving both security and performance. This design choice helps prevent unauthorized
access, minimizes the potential for network congestion, and ensures that storage traffic is not
impacted by other workloads or services on the network.
Create a dedicated VLAN:
By placing storage traffic on its own VLAN, the architect ensures further network segmentation. This
VLAN can be used exclusively for NFS traffic, improving both security and performance. It also allows
for easier management and monitoring of storage traffic, while helping prevent unauthorized access
from other parts of the network.
Question 10
An architect is tasked with designing the VMware Validated Solutions in an existing VMware Cloud
Foundation environment.
The design must meet the following requirements:
Must not allow logical networks to span physical network boundaries or locations
Must support static routing
What should the architect recommend based on these requirements?
- A. Overlay-backed NSX segments
- B. A dedicated distributed virtual switch and dedicated port groups
- C. VLAN-backed NSX segments
- D. A dedicated NSX segment configured manually
Answer:
C
Explanation:
VLAN-backed NSX segments meet the requirement of ensuring that logical networks do not span
physical network boundaries because VLANs are inherently limited to a single physical network
segment. Each VLAN maps to a specific Layer 2 broadcast domain and can be isolated to particular
physical network segments, ensuring that no logical network spans across physical boundaries.
Additionally, static routing is supported with VLAN-backed segments, providing the flexibility needed
to configure routing between different subnets or networks.
Question 11
Refer to the exhibit.
An architect is assigned a new project to design a VMware hybrid cloud solution.
The project is following a proven design methodology following the V-Model of systems engineering
and verification. The selected methodology follows these phases: Assess, Design, Deploy and
Validate.
Which activity would be conducted during the Design phase?
- A. The architect conducts a series of group interviews with stakeholders
- B. The architect helps stakeholders learn the mechanics of the solution
- C. The architect resolves configuration issues and addresses concerns
- D. The architect defines the scope of the project
Answer:
A
Explanation:
Design phase: The purpose of the Design phase is to define how the solution will meet the specific
requirements. During this phase, the architect works closely with stakeholders to understand their
needs and translate those needs into a technical design. A key activity in this phase often involves
refining the solution details through interviews and discussions with key stakeholders to ensure that
the design aligns with the business and technical requirements.
Question 12
An architect is working on the design documentation for a new vSphere solution. The architect has
completed a conceptual model based on the following requirement:
REQ001 – The solution must use shared storage
What could the architect include in the logical design to meet this requirement?
- A. The use of an NFS mount point, including the IP address of the NFS server it is hosted on
- B. The use of an all flash vSAN datastore
- C. The use of an HCI solution for a datastore
- D. The use of File Based Storage, including the list of permissions applied to the share
Answer:
A
Explanation:
The requirement specifies that the solution must use shared storage, which refers to a storage
solution that can be accessed by multiple ESXi hosts simultaneously. NFS (Network File System) is a
widely used method for providing shared storage in a vSphere environment. By including the NFS
mount point and the IP address of the NFS server, the architect can specify how the shared storage
will be configured and accessed by the ESXi hosts, meeting the requirement for shared storage.
Question 13
An architect is designing a vSphere-based private cloud solution to support the following customer
requirements:
The solution should support running 5,000 concurrent production compute workloads across the
primary and secondary sites.
The solution should support running 1,000 development compute workloads within the secondary
site.
The solution should support up to 50 management workloads across the primary and secondary site.
The solution must ensure the isolation of virtual infrastructure management operations between
management and compute workloads.
The solution must ensure that hosting of any virtual infrastructure management workloads does not
impact the amount of capacity available for compute workloads.
The solution must ensure that all production compute workloads are physically isolated from
development compute workloads.
The solution must ensure that the operational management of compute workloads in the secondary
site is possible in the event of a disaster affecting the primary site.
A combination of which four design decisions should the architect make to support the
requirements? (Choose four.)
- A. The solution will deploy a VMware vCenter instance in each management domain for the virtual infrastructure management of management workloads.
- B. The solution will deploy a VMware vCenter instance in the secondary site management domain for the virtual infrastructure management of production compute workloads.
- C. The solution will deploy a VMware vCenter instance within the primary site management domain for hosting all management virtual machines.
- D. The solution will deploy a VMware vCenter instance in the primary site management domain for the virtual infrastructure management of production compute workloads.
- E. The solution will deploy a VMware vCenter instance in the primary site management domain for virtual infrastructure management of production and development compute workloads.
- F. The solution will deploy a VMware vCenter instance in the secondary site management domain for the virtual infrastructure management of production and development compute workloads.
- G. The solution will deploy a separate management domain within each site for hosting local management workloads only.
Answer:
A, B, D, G
Explanation:
VMware vCenter instance in each management domain for the virtual infrastructure management of
management workloads:
The customer requires isolation between management and compute workloads. By deploying
vCenter instances in dedicated management domains, the management workloads can be handled
separately from production and development compute workloads, ensuring isolation.
VMware vCenter instance in the secondary site management domain for the virtual infrastructure
management of production compute workloads:
The secondary site should also have a vCenter instance for the management of production compute
workloads. This ensures that operational management of production workloads is still possible even
in the event of a disaster affecting the primary site, which aligns with the requirement to ensure the
management of compute workloads in the secondary site.
VMware vCenter instance in the primary site management domain for the virtual infrastructure
management of production compute workloads:
A vCenter instance in the primary site management domain should handle the management of
production compute workloads. The primary site is typically where most production workloads
reside, and having the vCenter instance here ensures that management operations can be performed
efficiently.
Separate management domain within each site for hosting local management workloads:
To ensure that management operations are isolated and that the management workloads do not
affect compute workloads, a separate management domain should be deployed in each site. This
ensures that the management functions do not consume compute resources that are intended for
production or development workloads.
Question 14
An architect is tasked with designing a new vSphere environment for a customer. The new
environment must:
Be standardized, repeatable, and consistent
Contain the same common heterogenous components that run from commercial hardware across an
on-premises, edge, and broad hybrid cloud eco-system
Provide intrinsic and intelligent security in every component from the hypervisor to the storage,
networking, and management layers
Which VMware solution will satisfy these requirements?
- A. VMware Cloud Foundation
- B. VMware Validated Design
- C. VMware
- D. VMware Validated Solutions
Answer:
A
Explanation:
VMware Cloud Foundation is an integrated solution that provides a standardized, repeatable, and
consistent architecture for deploying and managing a vSphere-based environment. It is designed to
run on heterogeneous hardware across on-premises, edge, and hybrid cloud environments. VMware
Cloud Foundation integrates compute, storage, and networking in a single solution, making it ideal
for environments that span multiple locations, including edge and hybrid cloud ecosystems.
VMware Cloud Foundation includes intrinsic and intelligent security features across the entire stack -
from the hypervisor to storage, networking, and management layers, which aligns with the
customer's security requirements.
Question 15
An architect is reviewing the information provided by a customer for a new vSphere solution design.
The customer requests that the solution use multiple network connections for the ESXi management
network to increase resilience.
- A. Availability
- B. Manageability
- C. Performance
- D. Recoverability
Answer:
A
Explanation:
The customer's request to use multiple network connections for the ESXi management network is
aimed at improving the resilience of the network, which directly supports the availability of the
management network. By using multiple network connections (such as NIC teaming), the solution
ensures that if one network connection fails, the other connections can maintain connectivity, thus
improving the availability of the ESXi management network.
