Question 4

As an OCI architect, you are designing a cloud environment to accommodate an on-premises Data Center workload, which currently has a memory oversubscription ratio of 2:1.

Deploy a Resource Manager Stack to launch the Compute instance with the replicated Block Volume

C.

Create a Compute instance with an attached Block Volume and configure the Hydration Agent to transfer the replicated data into the Block Volume

Question 6

You are working on a migration initiative as part of a cloud transformation project and leveraging Oracle Cloud Migrations service. Which is a valid use case for Oracle Cloud Migrations service?

Question 7

You are setting up Oracle Cloud Migrations (OCM) service for migrating workloads to Oracle Cloud Infrastructure (OCI). As part of the initial configuration, a Source Environment is created with Remote connection agents and Agent Dependency. However, the Replication plugin indicates the status as Inactive. What is the likely reason for this issue?

Options:

A.

The replication plugin does not support encrypted VM disk files

B.

The OCI tenancy has exceeded its service limit for compute instances, preventing the replication plugin from provisioning necessary resources

C.

The source VMs are using an unsupported file system that the replication plugin is unable to process

D.

The VDDK (Virtual Disk Development Kit) file required by the replication plugin is missing inthe OCI Object Storage

Question 8

Your company is looking to migrate its IT infrastructure into Oracle Cloud VMware Solution (OCVS). The source infrastructure includes a variety of workloads, such as a few business-critical VMs that require continuous availability, and a large set of non-critical dev-test VMs. As a migration cloud architect, you are exploring Hybrid Cloud Extension (HCX) migration methods to identify the best approaches for each type of workload. Which HCX migration method would be the most appropriate to use in order to migrate both business-critical VMs and dev-test VMs?

Options:

A.

HCX Bulk Migration for migrating business-critical VMs and HCX vMotion for non-critical dev-test VMs

B.

HCX vMotion for migrating business-critical VMs, and Cold Migrations for non-critical dev-test VMs

C.

Cold Migration for migrating both business-critical and non-critical dev-test VMs

D.

HCX Bulk Migration for migrating the business-critical VMs, and Cold Migrations for non-critical dev-test VMs

Question 9

What is the primary purpose of deploying a Remote Agent Appliance in an on-premises environment when using the Oracle Cloud Migrations (OCM) service?

Options:

A.

To perform real-time data compression and deduplication of the source data to be transferred to OCI

B.

To serve as a temporary storage buffer to cache data before it is transferred to OCI

C.

To facilitate direct VPN connectivity between the on-premises data center and OCI

D.

To discover on-premises workloads and provide detailed inventory information to OCI

Question 10

Which three transfer mediums does the OCI Database Migration service use to perform the initial load of the databases?
