CompTIA Network+ (N10-006) — Question 90

A technician is setting up a new network and wants to create redundant paths through the network.
Which of the following should be implemented to prevent performance degradation?

Answer options

• A. Port mirroring
• B. Spanning tree
• C. ARP inspection
• D. VLAN B

Correct answer:

Explanation

The correct answer is B. Spanning tree is designed to eliminate loops in network topologies, allowing for redundant paths without causing broadcast storms or performance degradation. The other options, such as port mirroring, ARP inspection, and VLAN B, do not address loop prevention and could lead to network inefficiencies.
