NS0-521 Question #68: Real Exam Question with Answer & Explanation

The correct answer is A. Modify the Cisco Nexus switches to use an MTU of 9216. C. Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216.. For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required: Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packe

Question

When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)

Options

AModify the Cisco Nexus switches to use an MTU of 9216.
BModify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9000.
CModify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216.
DModify the Cisco Nexus switches to use an MTU of 9000.

Explanation

For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required: Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance. Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216: This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
