CompTIA Cloud+ (CV0-003) — Question 339

A systems administrator for an e-commerce company will be migrating the company's main website to a cloud provider. The principal requirement is that the website must be highly available. Which of the following will BEST address this requirement?

Answer options

• A. Vertical scaling
• B. A server cluster
• C. Redundant switches
• D. A next-generation firewall

Correct answer: B

Explanation

A server cluster is the best choice for ensuring high availability as it allows multiple servers to work together, providing redundancy and failover capabilities. Vertical scaling, while it can increase capacity, does not inherently provide redundancy. Redundant switches offer network reliability but do not directly impact website availability, and a next-generation firewall is focused on security rather than availability.
