CompTIA Cloud+ (CV0-003) — Question 281

A systems administrator is planning to deploy a database cluster in a virtualization environment. The administrator needs to ensure the database nodes do not exist on the same physical host. Which of the following would best meet this requirement?

Answer options

• A. Oversubscription
• B. Anti-affinity
• C. A firewall
• D. A separate cluster

Correct answer: B

Explanation

The correct answer is B, Anti-affinity, as it ensures that certain virtual machines do not run on the same physical host, fulfilling the requirement for database nodes. Oversubscription (A) involves allocating more resources than available, which does not address the physical host placement. A firewall (C) is related to security and does not affect the physical location of nodes, and a separate cluster (D) could work but is not as efficient as using anti-affinity rules to manage node placement.
