Question 5

You are a migration architect responsible for managing data storage solutions in Oracle Cloud Infrastructure (OCI). You configured a Storage Gateway file system on a local host running in an on-premises datacenter, which maps to an Object Storage bucket with an identical name in OCI. What happens when a file is written to a Storage Gateway file system?

Options:

A.

The file is stored locally on the host machine

B.

The file is written as an object with the same name in the associated Object Storage bucket

C.

The file is uploaded to OCI Object Storage synchronously

D.

The file is replicated to multiple Object Storage buckets for redundancy

Question 6

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?

Options:

A.

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

B.

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

C.

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

D.

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

E.

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

Question 7

Your organization is in the stage of planning a migration of on-premises workloads to Oracle Cloud Infrastructure (OCI) using Oracle Cloud Migrations (OCM). As a migration architect, you are setting up the service to discover workloads. The initial step in this process involves the creation of Asset Source. Which statement accurately describes Asset Source?

Options:

A.

Is a remote virtual appliance deployed in the on-premises environment for discovery purposes

B.

Represents a repository within OCI where migrated assets are temporarily stored before being deployed into their final configuration

C.

Consists of credentials and connectivity details required by OCM to access and communicate with the on-premises environment

D.

Provides real-time cost analysis and optimization recommendations for assets during the migration planning phase

Question 8

You are planning to migrate an Oracle database from an on-premises data center to OCI Database service. Which two can be used for the migration?

Question 9

In the context of Oracle Cloud Infrastructure (OCI) Object Storage replication, what happens to objects that were uploaded to the source bucket before the replication policy was created?

Options:

A.

Are automatically deleted from the source bucket

B.

Are asynchronously replicated to the destination bucket upon policy creation

C.

Are immediately replicated to the destination bucket upon policy creation

D.

Are not replicated

Question 10
