• Question 52:

  You have an SVM that serves LUNs to your hosts in an FC SAN environment. This SVM runs on a 4-node cluster and has two data LIFs on each node, according to best practices. You just created a LUN and

  mapped it to your initiators group. The LUN is owned by node01. In this scenario, what would be an appropriate test for LUN mobility?

  A. Move the LUN to node02.

  B. Mirror the LUN to another node in your cluster.

  C. Physically disconnect the SAN ports, and verify if the SAN data LIFs automatically move to other hosts.

  D. Copy the LUN to another node and create a new LUN map.

  Correct Answer: A

• Question 53:

  While expanding a 200 GB LUN in an ONTAP 9.4 system, the following error is observed:

  

  What is the cause of this error?

  A. The volume auto-grow is disabled.

  B. The LUN reached maximum capacity.

  C. The LUN can be expanded up to 10 times its original size.

  D. Space reservation is enabled.

  Correct Answer: A

• Question 54:

  Click the Exhibit button.

  

  You have a LUN owned by Node 01 and mapped using the default Selective LUN Map (SLM) configuration. You want to enable your host to access this LUN and facilitate future maintenance.

  Which best-practice zone configuration accomplishes this task?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 55:

  Click the Exhibit button.

  

  Referring to the exhibit, you have SAN LUNs on an AFF A700s and are asked to test an SSD shelf stack failure.

  What is the maximum allowed number of failed paths per controller to shelf stack before a storage failover occurs?

  A. 1

  B. 3

  C. 2

  D. 4

  Correct Answer: C

• Question 56:

  You are planning to implement a 32 Gb FC SAN on a 2-node AFF A700 ONTAP 9.5 cluster. You need to create 112 FC LIFs across the HA pair with a limit of 20 FC LIFs per physical HBA port.

  In this scenario, how many 2-port 32 Gb HBA cards do you need per storage controller?

  B. 1

  C. 4

  D. 3

  Correct Answer: A

• Question 57:

  Click the Exhibit button.

  

  You configured a SAN host with a 4-node ONTAP 9.5 cluster that uses default settings. All paths are available from the host to the four nodes. You have a requirement to see only two paths to each LUN. One path is optimized and the other is non-optimized.

  In this scenario, which NetApp SAN feature supports this requirement?

  A. portsets

  B. SLM

  C. VLANs

  D. igroups

  Correct Answer: C

• Question 58:

  You have a 4-node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of storage space. AFF A300 LUNs that use under 5000 IOPS are moved to a FAS8200 using the lun move command.

  In this scenario, what happens to the data after the LUN is moved? (Choose two.)

  A. The new written data is not compacted.

  B. The new written data is compacted.

  C. The existing data is compacted.

  D. The existing data is not compacted.

  Correct Answer: BD

• Question 59:

  You are planning to expand a SAN-only ONTAP 9.5 cluster that consists of eight AFF A700 nodes. In this scenario, what is the maximum number of additional AFF A700 nodes that would be added?

  A. 2

  B. 4

  C. 8

  D. 0

  Correct Answer: B

• Question 60:

  Automatic host-side space management with SCSI T10 thin-provisioned LUNs is achieved by which feature of ONTAP?

  A. fractional reserve

  B. space allocation

  C. space reservation

  D. volume auto-grow

  Correct Answer: B
