Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 456

Which common threat can be prevented by implementing port security on switch ports?

Answer options

• A. VLAN hopping attacks
• B. spoofing attacks
• C. denial-of-service attacks
• D. eavesdropping attacks

Correct answer: B

Explanation

Port security primarily helps in preventing spoofing attacks by controlling which MAC addresses are allowed on a port. While VLAN hopping, denial-of-service, and eavesdropping attacks are significant threats, they are not directly addressed by port security measures.
