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.
A storage administrator selects 11 drives with RAlD 5 protection for a new Dynamic pool.
What is the RAID width of the new pool?
- A . 10+1
- B . 9+2
- C . 8+1
- D . 9+1
A storage administrator performs a monthly performance analysis of a Dell Unity XT storage array using CloudlQ insight reports. Three LUNs are set with a Host IO Limits policy The administrator discovers that the throughput IOPS on one LUN (Test_LUN) has increased by 1000 lOPS compared to the two previous months
What is the cause of the spike in lOPS?
- A . Test_LUN was expanded by 10o GB and a Density-based Host IO limit policy was set for all three LUNs.
- B . Test_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set only for Test_LUN.
- C . Another Absolute Host lO limit policy with additional 10oo IOPS was set on Test_LUN.
- D . Host IO limit of Test LUN was edited and the limit was increased by 1000 IOPS.
An administrator made writes to the storage resource using Redirect on Write architecture.
What is the size of slices that are allocated from the parent pool?
- A . 64 KB
- B . 8 KB
- C . 64 MB
- D . 256 MB
A storage administrator needs to test a new version of an application loaded on a secondary host. The administrator must use existing data contained on a LUN provisioned from a Dell Unity XT to a primary host.
Which approach satisfies the requirement and provides space efficiency?
- A . Create an Asynchronous Replication session for the LUN.
Configure access to the replica LUN for the secondary host.
Attach the secondary host. - B . Create a Synchronous Replication session for the LUN.
Configure access to the replica LUN for the secondary host.
Attach the secondary host. - C . Create a Snapshot of the LUN.
Configure LUN access for the secondary host.
Attach the Snapshot to the secondary host. - D . Create a Snapshot of the LUN.
Configure secondary host connectivity to Dell Unity XT.
Attach the Snapshot to the secondary host.
What two parameters are necessary when creating a host configuration for an NFS client? (Select 2)
- A . Hostname
- B . Subnet access
- C . Tenant information
- D . Network Address
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 the result of enabling data reduction on a LUN in a consistency group containing three LUNs?
- A . All writes to all consistency group LUNs will go through the data reduction logic.
- B . Data reduction will be enabled on all LUNs is the consistency group.
- C . Data reduction and advanced replication will be enabled on all LUNs
- D . Any writes to the LUN will go through the data reduction logic.
A Windows test server ran a stress test program that generated a large amount of throughput. This test resulted in performance slowdowns on production hosts sharing VMFS datastore.
What Dell Unity XT feature can a storage administrator use to prevent this problem?
- A . File System Quotas
- B . Host I/O Limits
- C . FAST Cache
- D . Bandwidth Schedules
A storage administrator set the following quota limits for the directory /Test in a Dell Unity XT system.
– Soft Limit of 10 GB
– Grace Period of 3 days
– Hard limit of 20 GB
Which user can write all data to the File System successfully?
- A . User4, Day1 write through 8 GB, Day2 write through 4 GB, and Day5 write through 5 GB
- B . User2, Day1 write through 12 GB, Day2 write through 1 GB, and Day5 write through 2 GB
- C . User3, Day1 write through 11 GB, Day2 write through 2 GB, and Day3 write through 5 GB
- D . User1, Day1 write through 8 GB, Day2 write through 12 GB, and Day3 write through 3 GB
