What should you do to enable ALUA to see the optimized paths?
- A. Update the reporting nodes for the LUN mapping.
- B. Update the MPIO policy to round-robin.
- C. Update the MPIO policy to most recently used.
- D. Update the igroup initiator WWPN.

NEW QUESTION 32
A customer created a new storage virtual machine (SVM) named "svm-nfs". They enabled only NFSv3 and created a new export policy called "Linux". In this policy, they created a rule replacing the default rule that shows the host specifier to be IP address 172.16.100.0/24.
This configuration has worked well for the past two weeks for all Linux clients. A new Linux client is about to be put into production but it is not able to access the NFS mount. The root user on this new client is not able to mount as well. They receive the "access denied" error.
Which statement is correct in this scenario?
- A. The volume is NTFS security style.
- B. The time on the controller is skewed by more than five minutes.
- C. The new client's IP address is not in the same subnet that is specified in the export policy rule.
- D. There is no export policy entry for the namespace for this export.
Answer: C
NEW QUESTION 33

In this scenario, which NVMe feature must be present and enabled for the client to see storage failover happen?
- A. Multi-Path I/O (MPIO)
- B. Asymmetric Namespace Access (ANA)
- C. NVMe Qualified Name (NQN)
- D. Asymmetric Logical Unit Access (ALUA)
