An administrator is configuring their environment using AppTemplate and wants to organize and be
able to search through the various templates they have created.
Which feature should the administrator use?
D
Explanation:
In managing and organizing environments using AppTemplate, the ability to quickly search and
categorize various templates is crucial. The use of Tags is highly effective in this scenario:
Tags: These allow for labeling templates with keywords or terms that make them easily searchable
and categorizable. Tags help in organizing templates by themes, purposes, environments, or any
classification that suits the administrative needs. This feature enhances manageability, especially in
environments with a large number of templates.
Annotations, Comments, and Pull Requests serve different purposes:
Annotations and Comments can be used to add descriptive or explanatory texts but do not facilitate
the searchability of templates in a structured manner like tags.
Pull Requests are typically used in version control systems for proposing changes and reviewing code,
not for searching or organizing templates directly.
Using tags in AppTemplate effectively streamlines the management and operational efficiency,
making it easier to locate and utilize templates as needed. Additional details on using tags can be
found in the user guide or help section of the AppTemplate tool.
An administrator is configuring a Red Hat Enterprise Linux system as a Workload Security Agent and
wants to make sure that it meets requirements.
Which two changes should the administrator make to the system? (Choose two.)
A, D
Explanation:
When configuring a Red Hat Enterprise Linux system as a Workload Security Agent, there are specific
system requirements and preparations needed to ensure compatibility and functionality of the
security agent. Among the potential adjustments:
Disable SELinux: Security-Enhanced Linux (SELinux) can interfere with the operation of various
security agents due to its strict access controls. Disabling SELinux may be recommended by certain
security applications to ensure they can function without restrictions. This should be carefully
considered in the context of overall system security policies.
Install the unzip application: Many security agents require unzip to extract and install necessary files.
Ensuring that unzip is installed on the system can facilitate the installation and updating of the
security agent.
Install the ansible-core application and Disable the system firewall are not typically required or
recommended universally for configuring a Workload Security Agent:
Ansible-core is used for automation and configuration management but is not a prerequisite for most
security agents unless specifically stated.
Disabling the system firewall can significantly reduce the system's security posture and is generally
not advisable unless specifically required by the security agent, and even then, such advice should be
critically evaluated.
For specific guidelines and requirements, the installation documentation of the Workload Security
Agent should be consulted.
An administrator deploys an FSx NetApp ONTAP in AWS as an archive destination. Which feature
must be disabled?
B
Explanation:
When deploying an FSx NetApp ONTAP in AWS as an archive destination, the daily automatic backup
feature must be disabled. This is because the primary purpose of an archive destination is to store
data that is infrequently accessed and does not require regular backups. Disabling daily automatic
backups helps in reducing unnecessary storage costs and resource usage associated with maintaining
daily backups of archival data.

How many VPCs are required to deploy CVO in Google Cloud?
C
Explanation:
To deploy Cloud Volumes ONTAP (CVO) in Google Cloud, typically two Virtual Private Clouds (VPCs)
are required. This configuration generally involves:
A VPC for the management of CVO operations, handling management traffic, control plane
operations, and other administrative activities.
A VPC dedicated to data traffic, ensuring data security and optimal network performance for storage
operations.
This dual-VPC architecture helps in isolating management operations from data operations,
providing enhanced security and performance. The management VPC can handle tasks like software
updates and system monitoring, while the data VPC focuses purely on serving storage requests,
thereby optimizing traffic flows and security policies accordingly.
For more detailed deployment instructions and VPC configuration guidelines, the official NetApp
documentation on deploying Cloud Volumes ONTAP in Google Cloud provides comprehensive
guidance.
A local ONTAP system has FabricPool configured to a public cloud. Storage use has grown
exponentially due to end-of-year activities. After a few weeks, tiering to the cloud stops.
What should the administrator do?
D
Explanation:
When tiering to the cloud stops in an ONTAP system configured with FabricPool, especially after a
rapid increase in storage use, it is likely due to reaching the capacity threshold of the aggregate.
ONTAP systems with FabricPool will halt tiering if the aggregate becomes too full. The solution is to
adjust the aggregate fullness, either by increasing the aggregate's capacity or by managing the
existing data more effectively (e.g., deleting unneeded data or moving data to another aggregate).
Configure tiering to a second cloud provider: This might help in distributing data, but it does not
address the issue if the problem is local aggregate capacity.
Increase the tiering license: Generally, tiering licenses are about the amount of data that can be
tiered rather than a technical limitation affecting tiering functionality.
Increase the cooling period: This might delay data movement but does not resolve the issue of
aggregate fullness halting tiering.
Adjusting the aggregate fullness directly addresses the root cause by ensuring there's sufficient
capacity within the local system to continue tiering operations. Information about managing
aggregate capacity in ONTAP systems can be found in the ONTAP management documentation or the
FabricPool administration guide.

An administrator configures FSx for ONTAP to use as storage in their cloud environment. The
administrator cannot access their NFS file system on clients located in another VPC.
What should the administrator configure?
A
Explanation:
To address the issue of not being able to access an NFS file system hosted on FSx for ONTAP in one
Virtual Private Cloud (VPC) from clients located in another VPC, the administrator should configure
VPC peering between the two VPCs. Here’s why and how:
VPC Peering Setup: VPC peering allows two VPCs to communicate with each other as though they
are part of the same network. This is essential for enabling direct access to the NFS file system across
different VPCs.
Configure Network Routes: Once VPC peering is established, configure the network routes to ensure
that traffic destined for the NFS file system can traverse the peered VPC connection.
Verify Accessibility: Test the NFS file system access from the client VPC to ensure that the
configuration is correct and that the file system is accessible.
VPC peering is a straightforward solution that does not require the complexity and additional cost
associated with options like Transit Gateways or Direct Connect. It’s well-suited for enabling direct
network connectivity between VPCs within the same cloud provider.
For more details on setting up VPC peering, refer to AWS documentation: AWS VPC Peering Guide.
An administrator must configure SVM-DR between two instances of Cloud Volumes ONTAP (CVO);
one is deployed in Azure, and the other in AWS.
What must be configured to enable replication traffic between the two CVO instances?
D
Explanation:
To enable replication traffic between two instances of Cloud Volumes ONTAP (CVO) deployed in
Azure and AWS, a Virtual Private Network (VPN) must be configured. This setup is crucial because it
provides a secure and private communication channel over the internet, which is necessary for the
replication of data between different cloud providers. Here’s the process:
Setup VPN Connection: Establish a VPN connection between the Azure and AWS environments. This
involves configuring VPN gateways in both clouds to enable encrypted traffic flow between the two
instances of CVO.
Configure Network Routing: Ensure that the routing rules are set to direct the replication traffic
through the VPN connection. This might include setting up appropriate route tables that point to the
VPN gateway.
Test and Verify Connectivity: After setting up the VPN, conduct tests to verify that the replication
traffic is flowing correctly and securely between the two cloud environments.
Using a VPN is the most straightforward and typically the most cost-effective method to securely link
AWS and Azure for the purpose of data replication, without the need for direct connectivity services
like AWS Direct Connect or Azure ExpressRoute, which are more complex and costly solutions.
For guidance on setting up VPNs between AWS and Azure, refer to the respective cloud provider’s
documentation on VPN configuration.
An administrator is configuring Cloud Volumes ONTAP (CVO). The CVO instance does not have
outbound network connectivity to send AutoSupport messages.
What will BlueXP automatically configure as the proxy server for AutoSupport?
D
Explanation:
In a scenario where a Cloud Volumes ONTAP (CVO) instance lacks outbound network connectivity to
send AutoSupport messages, BlueXP (formerly known as NetApp Cloud Manager) will automatically
configure the Connector as the proxy server for AutoSupport. The Connector serves as a bridge
between the customer's environment and NetApp cloud services, facilitating communication and
data transfer, including AutoSupport messages, when direct connectivity is unavailable.
Page blob is a type of storage in Azure, not related to network functions.
Mediator and Collector are not standard terms used within NetApp for describing components
involved in managing or proxying AutoSupport messages.
BlueXP's configuration to use the Connector as a proxy ensures that all monitoring and telemetry
data crucial for the health and performance diagnostics of the CVO instance are relayed effectively,
even in environments with restrictive outbound network policies. More details on this setup can be
explored in the BlueXP or Cloud Volumes ONTAP documentation available on NetApp's website.
A customer requires unlimited backups be included for their CVO instance. Which two subscription
models should the customer use? (Choose two.)
BC
Explanation:
For a customer requiring unlimited backups in their Cloud Volumes ONTAP (CVO) instance, the
Essentials and Premium subscription models are the appropriate choices. Both these subscription
models offer unlimited backups as part of their service package, which is ideal for customers who
prioritize extensive backup capabilities without the concern of hitting limits.
The Professional, Optimized, and Edge Cache plans typically have different focuses or limitations
concerning backup capabilities:
Professional: Geared more towards smaller or less critical deployments without the breadth of
features found in Premium or Essentials.
Optimized: Often focuses on performance optimization rather than extensive backup functionalities.
Edge Cache: Is used for caching services at the edge rather than core data management and backup
functionalities.
Detailed information on these subscription models and their backup capabilities can be found in the
NetApp Cloud Volumes ONTAP documentation or through consultation with NetApp sales
representatives.
An administrator wants to use BlueXP Observability to generate notifications whenever a volume in a
FlexGroup on a GCP CVO system is nearing capacity.

A
Explanation:
To generate notifications whenever a volume in a FlexGroup on a GCP CVO system is nearing capacity
using BlueXP Observability, the Data Collection API should be utilized. This option allows for the
configuration of customized monitoring and alerting based on specific data points and thresholds.
Here’s the process:
Setup Data Collection API: Configure the Data Collection API to monitor volume capacity metrics
within your FlexGroup. This involves setting up the API to pull or receive data points related to
storage utilization.
Define Alerts: Set thresholds for when capacity is considered nearing its limit (e.g., 80% full).
Configure alerts to be triggered when these thresholds are approached, ensuring administrators are
notified in advance to take necessary actions.
Implement Notification System: Integrate the alerting mechanism with your organization’s
notification system (e.g., email alerts, SMS, or a dashboard) to inform the relevant stakeholders or
administrators promptly.
For detailed instructions on configuring the Data Collection API and setting up monitoring and
alerting in BlueXP Observability, refer to the NetApp BlueXP documentation and API guides: NetApp
BlueXP Documentation.
