NEW QUESTION # 44
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?
- A. The OCI tenancy has exceeded its service limit for compute instances, preventing the replication plugin from provisioning necessary resources
- B. The VDDK (Virtual Disk Development Kit) file required by the replication plugin is missing inthe OCI Object Storage
- C. The source VMs are using an unsupported file system that the replication plugin is unable to process
- D. The replication plugin does not support encrypted VM disk files
Answer: B
Explanation:
The VDDK file is essential for the replication plugin to access and replicate VM disk files. If this file is missing in the OCI Object Storage, the replication plugin will be unable to function properly, resulting in an inactive status.
