CCIE Data Center (legacy) — Question 71

Enabling jumbo frame support on a Cisco Nexus 5500 Switch can be done through which method?

Answer options

• A. changing the default policy map from a default MTU of 1500 to 9216
• B. using the command system jumbomtu 9216
• C. using the command interface MTU 9216
• D. configuring the default Ethernet system class to an MTU of 9216 with a new network QoS policy map

Correct answer: D

Explanation

The correct answer is D because configuring the default Ethernet system class to an MTU of 9216 with a new network QoS policy map is necessary for jumbo frames. Option A changes the MTU but doesn't apply it correctly, while options B and C use incorrect commands that do not enable jumbo frame support.
