Correct Answer: C

Dell Unity XT MetroSync replication topology is a multi-site replication solution that allows you to replicate data synchronously between two or more Unity XT systems. In this topology, a source file resource is replicated synchronously from Site A to Site B, and also replicated synchronously from Site A to Site C. This means that data is written to the primary site and immediately replicated to the secondary site, ensuring that both sites have an exact copy of the data at all times. This type of topology is useful in cases where data loss is not acceptable and a zero RPO is needed. This topology ensures that the data is fully protected and that the environment is highly available, as in case of a primary site failure, the secondary site can take over.

Correct Answer: A

The minimum RPO (Recovery Point Objective) that can be configured on a Dell Unity XT block-asynchronous replication session is 5 minutes. RPO is a measure of how much data can be lost in the event of a disaster, and it's typically measured in minutes. The lower the RPO, the less data can be lost. Block-asynchronous replication is a replication method that copies data blocks, rather than files, between the source and the target. The data is copied at regular intervals, and if a disaster occurs at any point in time, the data on the target will be no more than 5 minutes old. The shorter the RPO, the more frequently data is copied and the less data is at risk of being lost in case of a disaster. It's important to note that this is the minimum RPO for block-asynchronous replication, it can be set to a higher value if needed.

Correct Answer: B

B, because the question is not mentioning "For Directory Services", DNS configuration is required. to create a NAS Server a DNS is not needed, only when you implement it in a AD Enviroment.

Correct Answer: B

7% is the recommended minimum amount of Flash that a technical architect should specify when designing a Dell Unity XT 480 using the System Designer option of Sizer. This is because, Unity XT storage systems require a certain amount of flash storage to handle system-wide functions such as metadata, snapshots and other storage services.

Correct Answer: B

In multiprotocol implementations (both SMB and NFS protocols enabled), an end�to-end mapping from Windows Security ID (SID) to UNIX User ID (UID) and Group ID (GID) is required.

Correct Answer: B

Dell Unity XT systems does not support mixing different drive types in the same RAID group. Adding larger drives to an existing RAID group with smaller drives will cause the operation to fail. The administrator should create a new RAID group with the larger drives and then copy the data from the old RAID group to the new one.
