Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 29

A network engineer is trying to prevent users from connecting unauthorized equipment to a production network. Which option can be implemented campus-wide to satisfy this requirement?

Answer options

• A. UplinkFast
• B. BPDU Guard
• C. private VLANs
• D. switchport block
• E. IP Source Guard

Correct answer: B

Explanation

The correct answer is BPDU Guard, which protects the network by preventing the formation of loops caused by unauthorized switches. Other options, like UplinkFast and private VLANs, do not specifically address the issue of unauthorized connections, while switchport block and IP Source Guard do not provide the same level of protection against rogue devices.
