CompTIA Network+ (N10-008) — Question 410

A technician is contracted to install a redundant cluster of devices from the ISP in case of hardware failure within the network. Which of the following would provide BEST redundant solution in Layer 2 devices?

Answer options

• A. Multiple routers
• B. Multiple switches
• C. Multiple firewalls
• D. Multiple bridges

Correct answer: B

Explanation

Multiple switches provide the best redundancy at Layer 2 because they can ensure continuous connectivity and load balancing in the event of a failure. Routers, firewalls, and bridges do not operate primarily at Layer 2, making them less effective for this specific requirement of redundancy in Layer 2 networks.
