Oracle Cloud Infrastructure 2022 Architect Professional — Question 48

An ISV partner wants to deploy their CRM application for one of its major clients on Oracle Cloud Infrastructure (OCI). The application will use an Oracle Database on OCI.
The client's business continuity requirements for the CRM application are:
Recovery Point Objective (RPO) of 24 hours
Recovery Time Objective (RTO) of 1 hour
The CRM application should be available even in the event that an entire OCI Region is down.
The ISV partner has asked you for advice on best practice to meet these requirements.
After reviewing Oracle Maximum Availability Architecture in OCI, what is your advice?

Answer options

• A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
• B. Deploy an Autonomous Transaction Processing database in one region and replicate it to an Autonomous Transaction Processing database in another region using OCI GoldenGate Service.
• C. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.
• D. Deploy an Autonomous Transaction Processing database in one region and replicate it to an Autonomous Transaction Processing database in another region using Autonomous Data Guard.

Correct answer: A

Explanation

The correct answer is A because deploying a single node VM Oracle database with manual Oracle Data Guard setup allows for the specified RPO and RTO, while also enabling cross-region replication. Options B and D, while viable for certain use cases, do not meet the specific continuity requirements as efficiently. Option C, although it provides high availability with Oracle RAC, does not align with the requirement for a simpler configuration and may complicate recovery processes.
