Question 43

A storage administrator is creating a host profile in Unisphere to provide host access to block storage resources using the iSCSI protocol. The host initiators were not automatically discovered and must be manually added.
In addition to the SAN host IQN, what other configuration can be performed through the "Create iSCSI Initiator Wizard" window?

A. Enable and disable CHAP settings
B. Create Mutual CHAP secret
C. Create Global CHAP secret
D. Enter CHAP username and secret

Correct Answer:D

Question 44

What is the correct sequence of steps taken by the storage array when an AC power failure is detected?
E20-393 dumps exhibit
Solution:

Storage processors Power
BIOS
SP Cache Array
The Battery Backup Unit (BBU) provides power to the Storage Processor in the event that cabinet power is lost. The BBU is designed to power the SP long enough for the system to store SP cache content to the M.2 SSD device before powering down. The BBU includes sensors which communicate its charge and health status to the SP. In the event the BBU is discharged the SP will disable cache until the BBU has recharged. In the event the BBU has faulted or cannot sustain enough charge, an alert will be generated.

Does this meet the goal?

A. Yes
B. No

Correct Answer:A

Question 45

Which task must be performed on the storage system in order to access a file system read/write snapshot?

A. Configure Host Access to the LUN snapshots
B. Configure the NFS/SMB share to the file system snapshot
C. Connect to the NFS/SMB share of the snapshot
D. Perform the snapshot “Attach to Host” operation

Correct Answer:B
Read-write snapshots can be made available to hosts as separate shares.
The Shared property is applicable to file snapshots only, and indicates whether the snapshot is currently available to clients as a share. The default value is No, and changes to Yes when the read-write file system snapshot is used to create shares. For read-only file system snapshots, this property is always set to No.
Share – A named, mountable instance of file-level storage, accessible through a file system or VMware NFS Datastore. Each share is accessible through the protocol (NFS or SMB) defined for the file system where it resides.
