Question #1

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

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

D. The replication plugin does not support encrypted VM disk files

Question #3

A team of migration cloud architects are evaluating different storage options for deploying virtual machines (VMs) in Oracle Cloud VMware Solution (OCVS). They are comparing VMware vSAN and OCI Block Storage to determine the best fit for their needs. Which two statements accurately reflect the usage of vSAN and OCI Block Storage in OCVS?

A. OCI Block Storage can be scaled up or down independently of compute resources, unlike vSAN which scales with the cluster

B. vSAN requires an external network connectivity to synchronize data across hosts, whereas OCI Block Storage does not

C. vSAN is tightly integrated with VMware's SDDC ecosystem, thus allowing for storage policies to be directly applied to VMs, whereas OCI Block Storage operates as independent block volumes

D. OCI Block Storage inherently provides better IOPS performance than vSAN for all workload types

E. OCI Block Storage can utilize VMware-specific storage policies for VM provisioning and management, just like vSAN in the OCVS environment

Question #4

How does the Copy to another region feature in Oracle Cloud Infrastructure (OCI) aid in achieving smooth transitions during Block Volume migration?

A. It replicates Block Volume backups to a target region, enabling smooth data migration

B. It ensures real-time data synchronization during migration for minimal downtime

C. It automates the migration process by transferring applications between regions

D. It compresses backup data before transferring, thereby expediting the migration process

Question #6

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?

A. Consolidate all databases into Exadata Database on Dedicated Infrastructure using Zero Downtime Migration

B. Use Oracle Estate Explorer to identify databases that can be migrated to Autonomous Database and the recommended method for migration

C. Group related databases and use the cloud premigration advisor tool to get consolidation recommendation

D. Group and migrate related databases into OCI Base Database service on multitenant architecture
