Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 167

Which two configurations cause the frames to be tagged? (Choose two.)

Answer options

• A. interface gi 0/1.116 encapsulation dot1q
• B. trunk allowed vlan 116
• C. interface with access and voice VLAN configured to 116

Correct answer: A, B

Explanation

Option A is correct because configuring 'encapsulation dot1q' on an interface explicitly tags the frames with the specified VLAN ID. Option B is also correct as allowing a specific VLAN on a trunk port means that frames for that VLAN will be tagged. Option C is incorrect because an access port does not tag frames; it forwards them untagged regardless of the voice VLAN configuration.
