Question # 1

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

Options:

A.  

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

B.  

It automates the migration process by transferring applications between regions

C.  

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

D.  

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

Question # 2

What is the primary purpose of the Oracle Cloud Balancer or OCI Native Ingress Controller during the implementation phase of Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) workloads?

Options:

A.  

Expose running workloads internally and externally

B.  

Conduct comprehensive testing and monitor performance metrics

C.  

Gradually shift traffic from the source environment to OKE

D.  

Efficiently manage packages with Helm charts

Question # 3

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

Question # 4

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 # 5

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 G

B.  

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?

Options:

A.  

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

B.  

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

C.  

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

D.  

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

Question # 6

Your corporate policy does not allow storing customer data outside of your organization. As part of a consolidation drive, you plan to migrate some of your critical Oracle databases to Oracle Autonomous Database. Which deployment option would you choose?

Options:

A.  

Autonomous Database on dedicated Exadata infrastructure

B.  

Exadata Database - Dedicated on Cloud@Customer

C.  

Exadata Database on Cloud@Customer

D.  

Autonomous Database on Cloud@Customer

Question # 7

What capability does Oracle Cloud Infrastructure (OCI) Storage Gateway provide for connecting on-premises applications with OCI Object Storage?

Options:

A.  

It enables seamless integration with on-premises databases for real-time data synchronization

B.  

It enables seamless integration with OCI Block Volumes for real-time data synchronization

C.  

It provides a bridge for applications to write data to OCI Object Storage using NFS protocol but requires application modification to uptake the REST APIs

D.  

It provides a bridge for applications to write data to OCI Object Storage using NFS protocol, without requiring modifications to the applications for REST API integration

Discussion 0
Question # 8

Which two represent an Oracle database migration scenario?

Options:

A.  

Changing the Oracle database host platform from Windows to Linux

B.  

Enabling encryption on your database

C.  

Changing the character set of the Oracle database

D.  

Upgrading the Oracle database from release 11g to 23c

Question # 9

One of your customers is planning to consolidate many of their single-instance databases into asuitable 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?

Options:

A.  

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

B.  

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

C.  

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

D.  

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

Question # 10

In Oracle Cloud Infrastructure (OCI), how are Security Lists different from Network Security Groups (NSGs) in terms of their functionality and application?

Options:

A.  

Security Lists offer more advanced features such as intrusion detection and prevention, whereas NSGs focus solely on packet filtering and routing

B.  

NSGs are primarily used for inbound traffic control, while Security Lists are exclusively utilized for outbound traffic control within a subnet

C.  

A Security List defines a set of security rules that applies to all the VNICs in a subnet whereas a Network Security Group lets you define a set of security rules that applies to a group of VNICs in a Virtual Cloud Network (VCN)

D.  

Security Lists and NSGs are identical in functionality but differ only in naming conventions based on the OCI region where they are deployed
