CCNA Routing and Switching (legacy) — Question 102

Which two circumstances can cause collision domain issues on VLAN domain? (Choose two.)

Answer options

• A. duplex mismatches on Ethernet segments in the same VLAN
• B. multiple errors on switchport interfaces
• C. congestion on the switch inband path
• D. a failing NIC in an end device
• E. an overloaded shared segment

Correct answer: A, C

Explanation

The correct answers, A and C, identify scenarios where duplex mismatches can disrupt communication within the same VLAN and where congestion on the switch's inband path can lead to collisions. Options B, D, and E do not directly cause collision domain issues; while they may affect performance, they do not create the same type of domain conflicts as the correct answers.
