NetApp NetApp Certifications NS0-520 Questions & Answers

• Question 171:

  An administrator is configuring a SAN-only cluster. The data room that houses four AFF A220 controllers is small and not able to house the DS224C shelves. The administrator proposes to rack the shelves in a separate room that is 40 meters away from the controllers.

  In this situation, how would you properly cable the controllers to the shelves?

  A. Use multimode passive optical cables.

  B. Use multimode active copper cables.

  C. Use multimode active optical cables.

  D. Use multimode passive copper cables.

  Correct Answer: C

• Question 172:

  You deployed a new SVM for FC access, and you used the vserver fcr, create -vserver svm1 - status-admin up command to enable FC service on the SVM. You then created the LIFs for the FC protocol. When you review the status of the LIFs, they show that the admin status is up, but the operational status is down. You have already verified that the ports are physically connected.

  In this scenario, what is the next step to bring the LIFs up?

  A. Use the network interface modify command to change the operational status of the LIFs.

  B. Create at least one zone that contains your SVM LIF WWPNs and an initiator.

  C. Verify that an FC license is applied on your system.

  D. Disable the SAN switch port where your NetApp storage is connected.

  Correct Answer: B

• Question 173:

  An administrator is configuring their Ethernet switches to support an AFF A300 cluster that will be providing iSCSI LUNs to servers. The switches are also used for other traffic from various hosts.

  In this scenario, which statement about the switch configuration is correct?

  A. Use a larger MTU size at the SAN connection rather than the host connections to allow for greater SAN bandwidth.

  B. Use network ports as access ports only.

  C. Use multiple VLANs to segregate iSCSI traffic from other traffic types

  D. Use a single VLAN to consolidate all data traffic on the switches.

  Correct Answer: A

• Question 174:

  You are configuring both NVMe and FC on the same AFF A700 2-node ONTAP 9.5 cluster. You are also configuring both protocols on the same FC fabric using the same A700 HBA ports.

  In this scenario, which three configurations are supported? (Choose three.)

  A. 16 GB HBAs

  B. 8 GB HBAs

  C. 16 GB fabrics

  D. 32 GB HBAs

  E. 32 GB fabrics

  Correct Answer: BCD

• Question 175:

  Which two are supported in ONTAP 9.5? (Choose two.)

  A. an NVMe LIF and an FC LIF in the same SVM

  B. an NVMe LIF associated with an FC Direct Connect port

  C. a NVMe LIF and an FC LIF associated with the same port

  D. multiple NVMe LIFs in the same SVM

  Correct Answer: CD

• Question 176:

  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 177:

  

  Referring to the exhibit, what happens when you change the type for port 1a from target to initiator?

  A. The port type for 1a changes to initiator, and you must reboot the controller for the changes to take effect.

  B. You receive an error message that you must take ports 1a and 1b offline before you can change the type.

  C. B. You receive an error message that you must take the port 1a offline before you can change the type.

  D. The port type for 1a and 1b changes to initiator, and you must reboot the controller for the changes to take effect.

  Correct Answer: A

• Question 178:

  What is a SAN best practice when initially configuring a Linux FC boot LUN?

  A. Install the Host Utilities in the guest Linux OS.

  B. Map the WWPN of the target.

  C. Disable the HBA port with the host's BIOS.

  D. Configure multipath to the LUN.

  Correct Answer: B

• Question 179:

  

  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 180:

  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
