Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 59

Which device must be responsible for properly marking network traffic when a Cisco IP phone is connected to a Cisco switch?

Answer options

• A. core layer switch
• B. access layer switch
• C. branch router
• D. Cisco IP phone B

Correct answer:

Explanation

The access layer switch is responsible for marking the traffic for devices such as Cisco IP phones because it handles user endpoint connections. The core layer switch primarily manages traffic between distribution layers, the branch router connects different networks, and 'Cisco IP phone B' does not serve a role in traffic marking.
