As a migrations architect, you are explaining the workflow of Oracle Cloud Migrations (OCM) service
to a business partner. After the replication of virtual machine (VM) data to Oracle Cloud
Infrastructure (OCI) using OCM, what is the next step to launch the migrated instance?
B
Explanation:
Deploying a Resource Manager Stack to launch the Compute instance with the replicated Block
Volume is the correct next step after the replication of VM data to OCI using OCM.
Your corporate policy does not allow storing customer data outside of your organization. As part of a
consolidation drive, you plan to migrate some of your critical Oracle databases to Oracle
Autonomous Database. Which deployment option would you choose?
D
Explanation:
Autonomous Database on Cloud@Customer is the correct option because it allows you to host
Oracle Autonomous Database within your organization's data center, meeting the corporate policy
requirements.
Which two are options for provisioning of Oracle Autonomous Database in the public cloud?
A, D
Explanation:
Serverless and Dedicated Exadata Infrastructure are valid options for provisioning Oracle
Autonomous Database in the public cloud.
What key benefit does Full Stack Disaster Recovery (FSDR) offer in Oracle Cloud Infrastructure (OCI)?
D
Explanation:
Full Stack Disaster Recovery (FSDR) offers the key benefit of seamless migration of VM workloads
between OCI regions.
Which two represent an Oracle database migration scenario?
A, D
Explanation:
Changing the Oracle database host platform from Windows to Linux and upgrading from release 11g
to 23c are typical migration scenarios.
What is the primary function of the Data Transfer Utility provided by Oracle Cloud Infrastructure
(OCI)?
D
Explanation:
The Data Transfer Utility is primarily used to prepare transfer disks for data shipment to Oracle's data
centers.
Which is the correct order of steps for setting up and using Oracle Cloud Infrastructure (OCI) Storage
Gateway?
1) Connect to the Storage Gateway File System.
2) Create a Storage Gateway File System.
3) Check whether your files are syncing to OCI Object Storage.
4) Download and install Storage Gateway.
5) Mount the Storage Gateway File System to your local system.
6) Log in to Storage Gateway Management Console.
B
Explanation:
The correct order of steps for setting up and using OCI Storage Gateway is: download and install the
Storage Gateway, log in to the Storage Gateway Management Console, create a Storage Gateway File
System, connect to it, mount it to your local system, and check whether your files are syncing to OCI
Object Storage.
A cluster of physical servers running in an on-premises data center is configured with a total of 100
GB physical memory. The total virtual memory allocated across all the VMs running on this cluster is
200 GB. Which term describes the virtual-to-physical memory allocation ratio for this cluster?
C
Explanation:
Oversubscription occurs when the total virtual memory allocated across all VMs exceeds the total
physical memory available in the cluster.
One of your customers is planning to consolidate many of their single-instance databases into a
suitable database solution in OCI. Their goal is to optimize resource utilization and reduce
maintenance and management overhead. What would you suggest as a migration architect?
B
Explanation:
Grouping and migrating related databases into OCI Base Database service on multitenant
architecture allows for efficient resource utilization and reduced management overhead.
Your company wants to expand its cloud infrastructure footprint by adopting Oracle Cloud VMware
Solution (OCVS). The OCVS Software Defined Data Center (SDDC) platform will be dedicated to
hosting business-critical workloads and should avoid single points of failure within its architecture.
Which two would be considered while setting up the solution?
B, C
Explanation:
OCI Fault Domains and vSAN Fault Domains are critical considerations to avoid single points of failure
and ensure high availability for business-critical workloads hosted on the OCVS SDDC platform.
You plan to perform migrations between on-premises and OCI. What is the minimum bandwidth
required with FastConnect as the dedicated network link between the environments?
D
Explanation:
The minimum bandwidth required for FastConnect is 1 Gbps to ensure fast and reliable data transfer
between the environments.
Which two are business goals of database migration?
B, D
Explanation:
Consolidating databases to optimize resource utilization and cost and reducing capital and
operational expenses are common business goals of database migration.
Your company is planning to decommission their on-premises data center hosting a set of Virtual
Machines (VMs) that heavily rely on VMware technologies. The goal is to migrate those VMs into
OCI, make this transition as quick as possible, ensuring the environment is highly available and can
be controlled by the company after the migration. What are the two advantages of using Oracle
Cloud VMware Solution (OCVS)?
A, B
Explanation:
Two key advantages of using OCVS are the ability to bring your own licenses (BYOL) for VMware
products, and the ability to move application VMs "as-is," minimizing the need for modifications.
You are planning to configure VMware Hybrid Cloud Extension (HCX) for a migration from an on-
premises data center to Oracle Cloud VMware Solution (OCVS). What are the primary roles of the
HCX Manager and HCX Connector?
B
Explanation:
The HCX Manager is responsible for initiating migrations and managing the migration process in the
source environment, while the HCX Connector receives the migration traffic in the target OCVS
environment.
Where is a Disaster Recovery (DR) Plan created in the OCI Full Stack Disaster Recovery service?
C
Explanation:
The Disaster Recovery (DR) Plan is created only at the Standby DR Protection Group in the OCI Full
Stack Disaster Recovery service.
