Question # 1

You are setting up replication in the Oracle Cloud Infrastructure (OCI) File Storage service. What is a key requirement for the target file system?

It must be located in a different region than the source file system

Only a file system that has been exported can be used as a target file system

It must not have been previously exported

It must be located in the same availability domain as the source file system

Question # 2

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?

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

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

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

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

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

Question # 3

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. The ratio means the total physical memory of the on-premises servers is 100 GB, and the virtual memory allocated is 200 GB. Upon source discovery, you discovered the actual physical memory utilization is below 50%. Which memory allocation strategy should you consider for the Bare Metal instances in OCI to optimize oversubscription, applying the actual utilization?

Bare Metal instances with total 150 GB of physical memory, providing a middle ground that acknowledges the oversubscription in on-premises

Bare Metal instances with total 250 GB of physical memory, anticipating potential spikes in memory demand

Bare Metal instances with total 75 GB of physical memory, considering the actual utilization in physical memory

Bare Metal instances with total 200 GB of physical memory to match the on-premises virtual memory allocation

Question # 4

What key benefit does Full Stack Disaster Recovery (FSDR) offer in Oracle Cloud Infrastructure (OCI)?

Simplified management of VM backups and restores

Accelerated deployment of VM configurations in OCI

Improved monitoring and performance optimization for VMs in OCI

Seamless migration of VM workloads between OCI regions

Question # 5

Which is NOT a benefit of using Hybrid Cloud Extension (HCX) for migrating Virtual Machines (VMs) to Oracle Cloud VMware Solution (OCVS)?

HCX facilitates the migration of VMs from non-VMware environments, such as KVM or Hyper-V

HCX upgrades the source environment to the latest vSphere version prior to migrating VMs

With HCX, the migrated VMs can retain their original IP addresses

HCX utilizes WAN optimization to accelerate migration traffic, making the migration process faster and more efficient

Question # 6

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?

The file is stored locally on the host machine

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

The file is uploaded to OCI Object Storage synchronously

The file is replicated to multiple Object Storage buckets for redundancy

Question # 7

You have set up cross-region replication for a block volume in the US West (Phoenix) region, choosing US West (San Jose) as the destination. Now, you want to create a new volume from the volume replica in the US West (San Jose) region. What should you do?

Trigger the replica

No action required. By default, the replica is available as a block volume

Activate the replica

Initialize the replica

Question # 8

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

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

It automates the migration process by transferring applications between regions

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

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

Question # 9

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

Data Pump via File Storage

Data Pump via Object Storage

Data Pump via network link

Data Guard via replication

Data Pump dump upload via OCI CLI

Question # 10

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?

Thick provisioning

Encapsulation

Oversubscription

Overprovisioning
