Public demo

CCNA demo scenario

This is an original sample format preview. It is not pulled from the live question bank.

A new access switch is connected to a distribution switch. Hosts in VLAN 20 can reach each other on the same switch, but they cannot reach VLAN 20 hosts on another switch. What should be checked first?

A. Whether the inter-switch link is configured as a trunk allowing VLAN 20.
B. Whether the host monitors use the same resolution.
C. Whether DNS has a record for every switchport.
D. Whether the default route uses a public DNS resolver.
Show answer and rationale

Answer: A

Same-switch VLAN communication proves the access VLAN exists locally. Failure across switches points first to trunk encapsulation, allowed VLANs, native VLAN mismatch, or related layer 2 configuration.
