A storage administrator is monitoring the pool capacity of two identical Dell Unity XT systems. Each system has every LUN replicated to the other system and all replication sessions are in sync. Both systems are used for production storage. CloudiQ is receiving updates from both systems, but shows that one of them is filling up more quickly than the other.
What is the cause of this behavior?
- A . CloudlQ is not receiving the same amount of updates from one of the two systems.
- B . One of the Unity systems is used less than the other one.
- C . Dell Unity Data Reduction is not identically enabled on LUNs on both systems
- D . Dell Unity Data Reduction license is not enabled on one of the two systems.
The LUN Snapshot Attach to Host operation is being performed with Read/Write Access selected.
By default, what does the Dell Unity XT system do before beginning the attach process?
- A . Creates a copy of the Snapshot
- B . Detaches existing attached hosts from the LUN Snapshot tree
- C . Detaches the host from the Snapshots of any other LUN
- D . Creates a Snapshot of the LUN
What is a characteristic of FAST VP?
- A . Users can enable or disable FAST VP at the LUN level
- B . Once enabled, FAST VP data relocation runs in background at all times
- C . FAST VP optimizes data placement by moving 1 GB slices between disk tiers.
- D . Users can set the FAST VP data relocation rate.
A storage administrator is tasked with creating a DR solution for block and file storage resources. The company has multiple regional and international sites containing a mix of Dell Unity XT and Dell Unity VSA systems.
What are considerations for the storage administrator when creating the DR solution?
- A . Synchronous remote replication should be restricted to within 161 km (100 mi) between sites to keep latency below 10 milliseconds.
Block storage resources can be replicated synchronously and asynchronously. - B . Synchronous remote replication should be restricted to within 10o km (62 mi) between sites to keep latency below 10 milliseconds.
File and block storage resources can be replicated synchronously and asynchronously. - C . Asynchronous replication ensures zero data loss to the remote replica in disaster conditions.
File storage resources can be replicated synchronously and asynchronously. - D . Asynchronous replication over long-distance does not impact latency.
Asynchronous replication ensures zero data loss to the remote replica in disaster conditions.
What are two recommendations for configuring synchronous replication on a Dell Unity XT system? (Select 2)
- A . Session RPO must be set to zero
- B . Dataset to be less than 100 TB
- C . Latency below 10 milliseconds
- D . A maximum of 100 km (60 mi) distance
A system engineer must provision one storage pool to include 14 Extreme Performance Drives, 6 Performance Drives, and 9 Capacity Drives. During the creation process in Unisphere, they notice that the Performance Tier is grayed out and shows only two unused drives.
What is the cause of this issue?
- A . Drive Firmware must be updated.
- B . Unity Management Software requires a refresh.
- C . Drives must be reseated.
- D . System drives are not allowed in the storage pool.
A system administrator must mount a datastore to an ESXi host using NFSv4 with the NFS owner set to change/revoke access permissions.
Which permission level must be applied to the NFS datastore?
- A . Read/write, enable Root
- B . Read-only, enable Root
- C . Read-only
- D . Read/write
Refer to the exhibit.
Which two MD5 authentication mechanisms does the configuration support?
What is a consideration when expanding a dynamic pool?
- A . The maximum number of slices in a private LUN is 256.
- B . The maximum number of drives is 64 in a drive partnership group.
- C . The maximum number of drives is 16 in a RAlD Group.
- D . The minimum number of drives in a RAID 5 (4+1) RAID Group is 5.
What pathing options do Dell Unity XT systems support to provide a host with Fibre Channel access to block storage?
A Multipath and Single Path only
B. Single Path, Multipath, and Alternate Path
C. Alternate and Multipath only
D. Single Path and Alternate only
