Question 6

Your customer has a 2-node cluster with two FAS2554 controllers running clustered Data ONTAP 8.3. You want to upgrade non-disruptively to clustered Data ONTAP 8.3.1 using the rolling-upgrade method. Which two operations would you perform before issuing the ~storage failover takeover -ofnode NodeA~ command? (Choose two.)

  1. Upgrade the service processor of all nodes.
  2. Migrate all LIFs used for iSCSI and FC away from NodeA.
  3. Change the default boot image to the new image.
  4. Install the new software image an all nodes.

Question 7

You log in to a SnapMirror destination to review the system. Which scanner would you expect to see running?

  1. active bitmap rearrangement
  2. container block reclamation
  3. blocks used summary update
  4. deswizzler

Question 8

An administrator notices that the clustered Data ONTAP 8.2.3 controllers are less responsive than normal. You use OnCommand Performance Manager but do not see obvious problems, yet, this particular issue is constant. Users are starting to complain. Which tool would you use to collect data to help diagnose this issue?

  1. Perfstat
  2. Perfmon
  3. AutoSupport
  4. Performance Archive

Question 9

Click the Exhibit tab. The exhibit shows an overview of a customer's network design. The customer is experiencing ping loss. As part of the troubleshooting process, you receive output by using the ifgrp status command from the node shell. In this scenario, what is the customer's problem?

  1. The interface group on the controller is not using the default type, causing a connection mismatch with the switch.
  2. Link aggregation is not active on the switch, despite being in the design.
  3. Virtual interface (VIF) is deprecated in clustered Data ONTAP because the interface group is not working as it should.
  4. Virtual LANs (VLANs) are not used, which causes the interfaces to be overloaded.

Question 10

You are creating a disk-partitioned root aggregate. Which two rules are enforced automatically when accomplishing this task? (Choose two.)

  1. A RAID group cannot have more than one partition from the same disk.
  2. A RAID group can have more than one partition from the same disk.
  3. The only supported RAID type for aggregates containing root-data partitioned disks is RAID-DP.
  4. The only supported RAID type for aggregates containing root-data partitioned disks is RAID 4
