Cisco Certified Network Associate (CCNA) 200-301 — Question 186

The correct answer is D. Option D: There is a native VLAN mismatch.

Explanation

Frames in the native VLAN are untagged by default on an 802.1Q trunk. A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure. NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
