• Question 45:

  Click the Exhibit button.

  

  A customer has an issue with performance on an NVMe solution. The SVM is using all four ports shown in the exhibit.

  In this scenario, how would the customer improve the host performance? (Choose the best answer.)

  A. Change the SFP+ in the controllers from 32 Gbps to 64 Gbps.

  B. Move all of the network interfaces to port 2a.

  C. Move some of the network interfaces from 2a to 2c and 2d.

  D. Remove support of the FC protocol and only use NVMe.

  Correct Answer: A

• Question 46:

  Node A has taken over Node B. You solved the issue that caused the takeover and are now ready to resume normal operation.

  After initiating the storage failover giveback command, how are the aggregates given back? (Choose the best answer.)

  A. CFO aggregates are automatically given back, SFO aggregates must be manually given back.

  B. CFO aggregates and SFO aggregates are automatically given back.

  C. The root aggregate is automatically given back, CFO and SFO aggregates must be manually given back.

  D. SFO aggregates are automatically given back, CFO aggregates must be manually given back.

• Question 49:

  Click the Exhibit button.

  

  You are configuring a NetApp cluster to communicate on VLAN 1. However, the new LIF is unable to communicate with any host in the VLAN. The network administrator has configured the switch port as an access (untagged) port on VLAN 1 and says that the VLAN is non-routed.
