CompTIA Network+ (N10-008) — Question 679

A network technician is troubleshooting a port channel issue. When logging in to one of the switches, the technician sees the following information displayed:

Native VLAN mismatch detected on interface g0/1

Which of the following layers of the OSI model is most likely to be where the issue resides?

Answer options

• A. Layer 2
• B. Layer 3
• C. Layer 5
• D. Layer 6

Correct answer: A

Explanation

The issue is related to a VLAN mismatch, which operates at Layer 2 of the OSI model, where data link protocols manage VLANs. Layers 3, 5, and 6 do not deal with VLAN configurations, making them irrelevant to this specific problem.
