CompTIA Cloud+ (CV0-003) — Question 292

An environment has a dual-stack infrastructure in an active-active configuration in two separate data centers. Which of the following best describes replication between the two sites?

Answer options

• A. Data is moved constantly from the hot site to the warm site.
• B. Data is replicated every 15 minutes from one site to the other.
• C. Data is moved from one site to the other once per day.
• D. Data is synchronized in real time across the sites.
• E. Data is moved twice a day from Site A to Site B, and then from Site B to Site A.

Correct answer: D

Explanation

The correct answer is D because real-time synchronization ensures that both data centers are updated simultaneously, providing high availability and redundancy. The other options describe methods of data transfer that do not maintain the same level of immediacy and reliability as real-time synchronization.
