ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 146

Which command must you enter to prepare an interface to carry voice traffic?

Answer options

• A. Switch1(config-if)#switchport mode access
• B. Switch1(config-if)#switchport mode trunk
• C. Switch1(config-if)#switchport access vlan 10
• D. Switch1(config-if)#switchport host

Correct answer: B

Explanation

The correct answer is B, as configuring the interface as a trunk allows it to carry multiple VLANs, including those designated for voice traffic. Options A and D configure the interface in a way that limits it to a single VLAN, while option C specifies a VLAN for access, which does not enable trunking.
