CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 72

You work as a Network Administrator for McNeil Inc. The company has a TCP/IP-based network. Performance of the network is slow because of heavy traffic. A hub is used as a central connecting device in the network. Which of the following devices can be used in place of a hub to control the network traffic efficiently?

Answer options

• A. Repeater
• B. Bridge
• C. Switch
• D. Router

Correct answer: C

Explanation

A Switch is the correct answer because it can intelligently direct data packets to specific devices on the network, reducing congestion compared to a hub, which broadcasts data to all devices. A Repeater simply amplifies signals, a Bridge connects two network segments but does not manage traffic as effectively as a Switch, and a Router is used for directing traffic between different networks, not within a single network.
