Click the Exhibit button. A customer is testing a newly installed NetApp AFF A400 all-flash HA storage system. An SVM for FCP with a LUN on Node 1 has been configured, and a server has been connected as shown in the exhibit. For testing, the engineer plans to do a storage failover of Node 1. After the failover, what is the expected status of the marked path?

Answers
D.
Modify the Cisco Nexus switches to use an MTU of 9000.
Suggested answer: A, C

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.
