Question: 1

A Group Manager sees only one connection for a volume connected to a 2012 host that runs two iSCSI NICs.

What are three possible causes of this problem? (Choose three.)

A. The second iSCSI NIC doesNOThave flow control enabled.

B. The second iSCSI NIC doesNOThave Jumbo Frames enabled.

C. Multi-pathing was NOT applied on the initial connection.

D. Access control is set up for a single IP.

E. The second NIC does NOT have cable connected.

Answer: B, C, D

Question: 2

An engineer is creating snapshot schedules for a volume to protect against data corruption. Snapshots must be taken both hourly and nightly. Each schedule is configured for a max keep of 10. Snapshot borrowing is enabled. The default snapshot schedule has NOT been disabled.

What should be the expected max number of snapshots for this volume?

A. 20

B. 21

C. 10

D. 2

Answer: A

Explanation:

Maximumnumber of snapshots created by the schedule to keep. The default is 10 snapshots. The maximum is 512. Once the number of file system snapshots created by the schedule reaches the max-keep limit, the NAS service deletes the oldest snapshot before creating anew snapshot.

Note: Snapshot space borrowing allows you to temporarily increase the available snapshot space for a volume by borrowing from the snapshot reserve of other volumes and from pool free space. This enables you to prevent the oldest snapshots in your collection from being automatically deleted.

Question: 3

An engineer needs to migrate a volume from a live production pool to a newly created pool, but is unable to do so.

What must the engineer do before the migration can start?

A. Offline the volume before migrating.

B. Disconnect active iSCSI sessions to the volume

C. Disable encryption on the group

D. Add or move a member to the new pool.

Answer: D

Explanation:

Note: You can move a volume to a different storagepool only if the new pool has free space equal to the size of the volume and any snapshot reserve and local replication reserve for the volume. If the pool does not have enough space, the volume will not move.

Question: 4

A customer reports that a problematic array is acting up. The customer is able to open SAN HQ and provide a SAN HQ archive, but is unable to get to the Group manager GUI to initiate a diag log pull. The customer tries to use the Group IP address via FTP to retrieve previous diagnostic files, but that is also unsuccessful.

What other option should the customer use to retrieve logs?

A. SNMP transfer

B. Email delivery

C. Dump to console

D. Use HTTPS option

Answer: B

Explanation:

After gathering the log information, the EqualLogic Array will attempt to send them via E-Mail if you have this configured, you also have the option of outputting to a text file.

Question: 6

A new storage administrator (SA) is configuring replication on a newly created 1 TB volume. Management determines that asynchronous replication will be used.

The SA looks at the delegated space on the DR group and determines that there is NOT enough room to fit the replica set for the new volume.

Which action should the SA take at the DR site so that the new volume can be replicated?

A. Increase the delegated space.

B. Reduce the replica reserve on replicated volumes.

C. Reduce the volume by thin provisioning.

D. Increase the replica reserve on the new volume.

Answer: D

Explanation:

When the primary group administrator configures a volume for replication, the administrator assigns a portion of delegated space to the volume. This space, called replica reserve, limits the number of replicas thatyou can keep on the secondary group. You can modify the volume replication configuration and increase or decrease the replica reserve value, as needed.
