Question 6 of 56

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

✑ The new volume has 200 GB of used space.

✑ There is only 100 GB of space available on the DR group.

✑ Delegated space has only 50 GB of space still available.

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?

Answer

Suggested Answer

The suggested answer is D.

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 that you can keep on the secondary group. You can modify the volume replication configuration and increase or decrease the replica reserve value, as needed.

Question 7 of 56

A customer needs to use a Disaster Recovery (DR) site for replication. The customer provides the following information:

  • Volumes to replicate: 1
  • Volume size (total): 1.5 TB
  • Total data set size: 1 TB
  • Change rate: Averages 10% per hour

After setting up replication, the customer monitors the results. The volume replicates successfully only about 75% the time. The remaining time, no data is replicated. Although some replications have failed, no user intervention has occurred. The replication works on subsequent intervals.

Which action should be taken to ensure reliable replication?

Answer

Suggested Answer

The suggested answer is C.

If there is not enough free local replication reserve to complete a replication operation, one of the following occurs:
* If you did not enable the option to borrow free pool space, or if you enabled the option, but there is not enough free pool space, the primary group cancels the replication and generates an event message, stating that the replication was canceled.
* If you enabled the option to borrow free pool space, and sufficient free pool space is available (at least 10% free pool space), replication continues. The primary group generates an informational message, specifying that it is temporarily using free pool space during the replication.

Question 8 of 56

A customer needs a full, permanent, point-in-time, local copy of the data.

Which Dell PS Series feature should be configured to meet the requirement?

Answer

Suggested Answer

The suggested answer is D.

Snapshots are point-in-time copies of volumes that capture the contents of a volume at a specific point in time and are often used to recover data lost by events such as human error, viruses, or database corruption.
When a snapshot is created, it does not consume any space, but instead is only a set of pointers to the data in the base volume.

Question 9 of 56

A customer has a single-member group with a RAID policy of RAID 6 in the default storage pool. A second member with a RAID policy of RAID 10 is added.

What are two valid ways to add the second member? (Choose two.)

Answer

Suggested Answer

The suggested answer is A, D.

Setting the member RAID policy -
When a new group is created, or a new member is added to an existing group, the RAID policy must be selected before the space on the member is available

Incorrect: Answers -
B, C: The default pool has a RAID 6 policy.
Note:
RAID 10 Striping on top of multiple RAID 1 (mirrored) sets, with one or two spare disks (depending on the total number of disks in the array).
The figure below represents a RAID 10 configuration protected by RAID and two spare disks.

Question 10 of 56

Which three settings are unique when creating a thin volume? (Choose three.)

Answer

Suggested Answer

The suggested answer is C, D, F.

Thin provisioning settings controls whether the volume is thin-provisioned and, if so, the minimum and maximum volume reserve and the in-use space warning limit.
Note (see 5 below) : To modify the thin provisioning space settings:
1.Click Volumes.
2.Expand Volumes and select the volume.
3.Click Modify settings.
4.Click the Space tab to open the Modify volume settings Space dialog.
5.Use the sliders to adjust the settings for:
Minimum volume reserve
In-use space warning limit
Maximum in-use space (maximum volume reserve)
The Pool Space table values change, based on the new values. If a change exceeds capacity, the free pool space cell displays a negative value.
6.Click OK.
