NEW QUESTION 121
What is the default file system quota policy on the Dell EMC Unity XT storage array?

• A. File Size
• B. Tree Quotas
• C. User Quotas
• D. Blocks

Answer: A

Explanation:
When using quotas, administrators have the option to calculate file system usage in one of two ways. This option, which is configured on a per file system basis, may be set to File Size or Block based calculation. When using the default setting of File Size, disk usage is calculated based on logical file sizes in 1K increments.
Because of this, it is possible that used space may be reported from a quota perspective as more than the actual usage if holes exist in a sparse file. This setting is generally recommended for Windows environments.
The Block quota policy calculates disk usage in 8-16KB file system blocks, and is accurate with regard to the actual allocation down to the block level. This setting is recommended for UNIX environments.

NEW QUESTION 122
A system administrator wants to configure asynchronous replication on their Unity system. What is required
before creating a replication session?

• A. A Sync Replication Management Port configured on each system.A Fibre Channel connection
  configured between the remote systems.A configured replication connection between the remote
  systems.
• B. A Sync Replication Management Port configured on each system.An IP-based replication interface on
  the same network as the destination system's interface.A configured replication connection between the
  remote systems.
• C. A Fibre Channel connection configured between the remote systems.A configured replication
  connection between the remote systems.
• D. An IP-based replication interface on the same network as the destination system's replication
  interface.A configured replication connection between the remote systems.

Answer: B

Explanation:
Explanation
Asynchronous remote replication requires a replication interface be created on each SP on the system.
For asynchronous replication, replication is performed over Ethernet interfaces configured on the system. On
EMC Unity physical systems, the onboard 10GbE BaseT ports, CNA ports with Ethernet personality, or
Ethernet ports located on I/O modules can be used for replication. In UnityVSA systems, any I/O port can be
used for asynchronous replication.

NEW QUESTION 123
A storage administrator is required 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 Unity to a primary host.
Which solution will meet the requirement and provide space efficiency?

• A. Create a snapshot of the LUNConfigure snapshot access to the LUN for the secondary hostAttach the snapshot to the secondary host
• B. Create an Asynchronous Replication on session for the LUNConfigure access to the replica LUN for the secondary hostAttach the secondary host
• C. Create a Synchronous Replication session for the LUNConfigure access to the replica LUN for the secondary hostAttach the secondary host
• D. Create a snapshot of the LUNConfigure LUN access for the secondary hostAttach the snapshot to the secondary host

Answer: A

Explanation:
Explanation
Attaching a snapshot is only applicable for block snapshots, and makes the snapshot available for host IO. A host must have Snapshot access or LUN and Snapshot access configured in order to access the snapshot. When a snapshot is attached, Unisphere provides the option to create a copy of the snapshot in case the administrator wants to preserve the current snapshot view for future use.

NEW QUESTION 124

• B. Fibre Channel at 2/4/8/16 Gb/s and iSCSI at 10 Gb/s.
• C. FCoE at 10 Gb/s and iSCSI at 10 Gb/s
• D. Fibre Channel at 4/8/16 Gb/s and FICON at 8 Gb/s.
