CompTIA CASP+ (CAS-004) — Question 400

A company has a website with a huge database. The company wants to ensure that a DR site could be brought online quickly in the event of a failover, and end users would miss no more than 30 minutes of data. Which of the following should the company do to meet these objectives?

Answer options

• A. Build a content caching system at the DR site.
• B. Store the nightly full backups at the DR site.
• C. Increase the network bandwidth to the DR site.
• D. Implement real-time replication for the DR site.

Correct answer: D

Explanation

Implementing real-time replication for the DR site ensures that data is continuously synchronized, minimizing potential data loss to under 30 minutes. Options A and B do not provide adequate immediacy for data recovery, as caching and nightly backups would still result in significant downtime or data loss. Increasing network bandwidth (Option C) may improve performance but does not address data replication directly.
