The Secret Of EMC E20-393 Latest Exam

NEW QUESTION 1
A system administrator wants to configure asynchronous replication on their Unity system. What is required before creating a replication session?

• A. 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.A Fibre Channel connection configured between the remote systems.A configured replication connection between the remote systems.
• C. An IP-based replication interface on the same network as the destination system’s replication interface.A configured replication connection between the remote systems.
• D. 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.

Answer: D

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 2
A storage administrator wants to add as asynchronous replication session to a pair of Unity systems with an existing synchronous replication session that is operating correctly. Which configuration steps are needed?

• A. Create Replication interfaces on both systems.Modify the Replication Connection Mode.Run a Replication Connection Verify and Update operation.
• B. Create Replication Interfaces on the source system.Modify the Mode for Replication Connection.Perform a manual Sync operation on the Asynchronous session.
• C. Create Replication Interfaces on destination system.Establish FC connectivity using the Synchronous FC Ports of each system.Perform a manual Sync operation on the Asynchronous session.
• D. Create Replication Interfaces on both systems.Establish FC connectivity using the Synchronous FC Ports of each system.Run a Verify and Update operation for the Replication Connection

Answer: A

Explanation:
To fully configure asynchronous replication between systems, you must do each of following: Note: To fully configure synchronous replication, you must complete each of following:

NEW QUESTION 3
A storage administrator has added multiple resources to a single density-based Host I/O Limit policy for the following storage resources:
LUN A: 25 GB
LUN B: 25 GB
LUN C: 50 GB
Density-Based Limit 20 IOPS
What is the total IOPS set by this policy?

• A. 200
• B. 500
• C. 2000
• D. 2500

Answer: A

NEW QUESTION 4
What describes the LUN Snapshot Copy operation?

• A. Parent cannot be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent
• B. Parent can be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent
• C. Parent can be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy
• D. Parent cannot be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy

Answer: B

Explanation:
Note: You can create copies of LUNs by cloning LUNs from the Snapshot copies in a volume. These FlexClone LUNs are readable and writable copies of the LUNs as the LUN existed when the Snapshot copy was created. Before you can clone a LUN, you must create a Snapshot copy (the backing Snapshot copy) of the LUN you want to clone.

NEW QUESTION 7
A company needs to expand their dynamic pool by 5 TB. The current dynamic pool consists of sixty-three 3.8 TB SSD that are configured for RAID5 4+1.
What is the minimum number of drives needed for the pool expansion?

• A. 1
• B. 6
• C. 7
• D. 8

Answer: A

NEW QUESTION 8
Which quota policy calculates disk usage in 8 KB units?

• A. File Size
• B. Block
• C. User
• D. Directory Tree

Answer: B

NEW QUESTION 9
How long will a Copy Back operation take when a hot spare is invoked?

• A. Pro-Active hot spare does not use a Copy Back operation
• B. Copy Back time depends on the RAID type
• C. Copy Back time depends on the disk capacity
• D. Copy Back time depends on the disk type

Answer: B

Explanation:
Note: Starting with Release 24, you can now use a proactive hot spare for proactive disk replacement. Before Release 24 you had to remove the physical disk to replace in order to force a rebuild. During the rebuild phase, the RAID group was "degraded" and at risk.
Resolution:
Three main benefits of using a proactive hot spare: References: https://community.emc.com/docs/DOC-9419

NEW QUESTION 10

• A. 4Gb/s, 8 Gb/s, and 16 Gb/s
• B. 10 Gb/s and 16 Gb/s
• C. 8 Gb/s and 16 Gb/s only
• D. 1 Gb/s and 10 Gb/s

NEW QUESTION 11
A company has a VMware host installed with FC HBAs that is connected to a Dell EMC Unity XT storage array. A 500 GB LUN is provisioned to this host from the Unity array and is in production. The VMware administrator has configured a new vSwitch with the NICs on the server intended for iSCSI traffic. The storage administrator is asked to configure software iSCSI and provision a new 1 TB LUN from the storage array via iSCSI.
What is a consideration when satisfying this request?

• A. A connection must be established between the host iSCSI initiators and Unity iSCSI targets before provisioning the new LUN
• B. Any single host should connect to any single array using one protocol only
• C. The iSCSI configuration must use all the NIC connections to the host
• D. Two iSCSI target interfaces must be configured with IP addresses from separate subnets

Answer: D

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 physical and virtual Dell EMC Unity systems.
What are considerations for the storage administrator in creating the DR solution?

• A. Synchronous remote replication should be restricted to within 100 km between sites to keep latency below 10 msBlock storage resources can be replicated synchronously and asynchronously
