  B. Once LUN mapping planning is complete, the job is done.

  C. Final FC storage architecture is the sole requirement.

  D. Switch and controller management network connectivity must be verified.

  Correct Answer: D

• Question 72:

  When adding expansion FC adapter cards to NetApp controllers running ONTAP 8.1 Cluster Mode or above, which resource should be consulted for optimum placement of the new cards in the controller slots?

  A. Ethernet port on a controller

  B. File

  C. LUN

  D. Volume

  E. Vserver

  F. FC port on a controller

  Correct Answer: D

• Question 74:

  A solution is setup with a Volume Guarantee = volume, LUN reservation = off, Fractional Reserve = 0%, Snap Reserve = 0%, auto_delete = volume, auto_grow = on, try_first = autosize. Which of these choices best describes the use of these settings for our Space Policy?

  A. when you want to set aside overwrite reserve space for the LUNs so that writes never fail with the presence of Snapshots

  B. when you want to use thinly provisioned LUNs to overcommit the volume and increase storage efficiency

  C. when you want Data ONTAP to start deleting Snapshots to recover space from the volume before growing the volume

  D. when you want to guarantee space for Snapshots by letting the volume autogrow

  Correct Answer: D

• Question 75:

  A. All nodes in a cluster must have the same number of Fibre Channel target ports.

  B. All nodes in a cluster must have the same amount of storage capacity.

  C. All nodes in a cluster must have redundant connections to the cluster network

  D. All nodes in a cluster must be of the same storage controller model.

  E. Nodes may only be added in HA pairs.

  Correct Answer: CE

• Question 78:

  A storage administrator notices the FCoE traffic is only given 30% of the bandwidth allocation when a 10- GbE FCoE path becomes fully saturated. How can a storage administrator check the bandwidth allocation for a particular FCoE port in Data ONTAP Cluster Mode?

  A. There is no problem. This is the normal allocation and it cannot be changed.

  B. The problem cannot be detected on the storage. Check the switch.

  C. Use the dcb show command at the nodeshell

  D. Use the dcb show command at the clustershell.

  Correct Answer: C

• Question 79:

  What happens when a node loses SAN protocol quorum? (Choose two.)

  A. The node's HA partner initiates a takeover of the out of quorum node.

  B. The node continues serving data via SAN protocols, but only over direct paths.

  C. The node stops serving data via SAN protocols completely until it is rebooted.

  D. The node stops serving data via SAN protocols until the node quorum reinitialize command is executed.

  Correct Answer: BD

• Question 80:

  A. SAN traffic can utilize the management LIF's on the controllers

  B. One LIF can be used for both iSCSI and FC traffic

  C. Migrate when required for redundancy

  D. Provide connectivity to the host system for MPIO with ALUA path selection

  E. iSCSI and FC LIFs can utilize the same ports on a controller's UTA

  Correct Answer: CD
