• Question 131:

  When booting your NetApp storage system for the first time the system fails to boot.

  What should you do first to address this problem?

  A. You turn off your storage system and disk shelves, and then turn on the disk shelves. You then check the quick reference card that came with the disk shelf for information about LED responses.

  B. You re-download the boot image to the compact flash card, then reboot the system.

  C. You look for a description of the problem on the LCD and console. You then follow the instructions, if provided, on the LCD and console.

  D. You verify disk shelf compatibility and check the disk shelf IDs to verify that the disk shelf 1 (for DS14 series) must be connected to your system.

  Correct Answer: C

• Question 133:

  Exhibit.

  

  Dining a data mobility test on a 4-node ONTAP 9.3 cluster, the host loses direct access to its LUNs. The LUNs are hosting on node cl1-01 and are being moved to cl1-03 on a different HA pair. Referring to the exhibit, which corrective step is needed to ensure access while the volume is moved?

  A. Add reporting nodes for cl1-03 and cl1-04.

  B. Create additional LIFs on cl1-01 and cl1-02.

  C. Create a new destination volume on cll-03.

  D. Create new igroups on cl1-03 and cl1-04.

  Correct Answer: A

• Question 134:

  Exhibit.

  

  A customer is testing a dual-fabric FC SAN configuration as shown in the exhibit. The zones are implemented on the switches shown below.

  

  IF all the nodes are in the SLM reporting nodes list, how many paths per LUN should the customer expect when simulating a node failure by powering off Node 04?

  A. 4 paths

  B. 6 paths

  C. 8 paths

  D. 2 paths

  Correct Answer: B

• Question 135:

  Exhibit.

  

  A customer is testing a dual-fabric FC SAN configuration as shown in the exhibit and the zones are implemented on the switches shown below.

  

  If all the nodes are in the SLM reporting nodes list, hoe many path per LUN should the customer expect when simulating an FC SFP failure by bringing LIF_3 offline?

  A. 15 paths

  B. 3 paths

  C. 4 paths

  D. 7 paths

  Correct Answer: D

• Question 136:

  When setting up a VLAN for administrative security purposes, which four ports are the only important ports to include in the VLAN? (Choose four.)

  A. Storage Controllers Management Ethernet ports

  B. FC Switches Ethernet port

  C. Hosts iSCSI HBA Ethernet port

  D. Ethernet Switches Management port

  E. Storage Controller iSCSI Ethernet Target ports

  F. Hosts NIC Ethernet port

  Correct Answer: ABDF

• Question 137:

  You are setting up FC ports and must configure the speeds for both the SAN and the host ports. In this scenario, which statement is correct?

  A. Set the target port speed higher than the switch port speed.

  B. Set the target port speed to auto-negotiation.

  C. Set the target port speed to match the switch port speed.

  D. Set the target port speed lower than the switch port speed.

  Correct Answer: B

• Question 138:

  At which storage object level is deduplication enabled?

  A. Aggregate

  B. Volume

  C. Qtree

  D. LUN

  Correct Answer: B

• Question 139:

  You are about to replace a failed Brocade Fibre Channel switch. Which three steps do you take prior to connecting the switch in the SAN? (Choose three.)

  A. Force the new switch to be the principle switch.

  B. Change the domain ID of the replacement switch to the domain ID of the failed switch.

  C. Clear all zoning configurations on the replacement switch.

  D. Change the core PID format of the replacement switch to the core PID format of the failed switch.

  E. Preload the zoning information from the fabric onto the new switch.

  Correct Answer: BCD

• Question 140:

  A4-node ONTAP FAS9000 cluster was used to serve I/O from six RedHat 7.3 servers. The servers were configured with maximum, queue depth.

  For production purposes, an additional 60 similarly configured hosts were added to the environment. Later, the hosts started reporting random QFull errors, and the aggregated performance degraded.

  Which two solutions would alleviate the QFull errors and performance problems? (Choose two.)

  A. Remove Selective LUN Mapping (SIM) from the 4-node FAS9000 cluster.

  B. Download the latest FC HBA driver, firmware, and BIOS, and deploy them on the hosts.

  C. Configure and use additional FC target HBAs in the FAS9000 cluster.

  D. Reduce FC HBA gueue depth on the hosts.

  Correct Answer: CD
