CompTIA Network+ (N10-009) — Question 204

A network administrator is installing a network for a small company. The switches will be installed in parallel to provide redundancy in case a specific device fails. Which of the following should be configured to prevent loops?

Answer options

• A. Spanning tree
• B. CRC
• C. Jumbo frames
• D. Link aggregation

Correct answer: A

Explanation

The correct answer is A, Spanning tree, which is specifically designed to prevent loops in a network by creating a loop-free topology. Options B (CRC) and C (Jumbo frames) do not address loop prevention, while D (Link aggregation) focuses on increasing bandwidth rather than preventing loops.
