CompTIA Network+ (N10-008) — Question 66

A network administrator is implementing OSPF on all of a company's network devices. Which of the following will MOST likely replace all the company's hubs?

Answer options

• A. A Layer 3 switch
• B. A proxy server
• C. A NGFW
• D. A WLAN controller

Correct answer: A

Explanation

A Layer 3 switch is capable of performing routing functions, which aligns with OSPF's requirements for routing protocols, making it the most suitable replacement for hubs. The other options, such as a proxy server, NGFW, and WLAN controller, serve different purposes related to security and wireless connectivity, but do not replace the basic functionality of hubs in a network.
