Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 142

An engineer implements QoS in the enterprise network. Which command is used to verify the correct classification and marking on a Cisco IOS switch?

Answer options

• A. show class-map interface GigabitEthernet 1/0/1
• B. show policy-map interface GigabitEthernet 1/0/1
• C. show policy-map
• D. show access-lists

Correct answer: B

Explanation

The correct command to verify QoS classification and marking is 'show policy-map interface GigabitEthernet 1/0/1', as it provides details on the applied policy-map for that specific interface. Other options, such as 'show class-map' and 'show access-lists', do not provide the necessary information regarding QoS policies applied to the interface.
