CompTIA Cloud+ (CV0-003) — Question 80

A cloud administrator is monitoring a database system and notices an unusual increase in the read operations, which is causing a heavy load in the system. The system is using a relational database and is running in a VM. Which of the following should the administrator do to resolve the issue with minimal architectural changes?

Answer options

• A. Migrate the relational database to a NoSQL database
• B. Use a cache system to store reading operations
• C. Create a secondary standby database instance
• D. Implement the database system using a DBaaS

Correct answer: B

Explanation

The correct answer is B because using a cache system can alleviate the load by reducing the number of read operations that hit the database directly, improving performance while keeping the existing architecture intact. Option A suggests a major change to a NoSQL database which may not be necessary, C involves creating a standby instance which doesn't directly address the load issue, and D would require significant changes to the deployment model.
