CompTIA Server+ (SK0-005) — Question 132

Which of the following ensures a secondary network path is available if the primary connection fails?

Answer options

• A. Link aggregation
• B. Most recently used
• C. Heartbeat
• D. Fault tolerance

Correct answer: D

Explanation

Fault tolerance is the ability of a system to continue operating properly in the event of the failure of some of its components, such as a primary network connection. Link aggregation combines multiple network interfaces to increase bandwidth but does not inherently provide a backup path. Most recently used and heartbeat are not related to ensuring a secondary network path.
