What is a specific configuration guideline that should be followed when configuring Linux hosts to support XtremIO storage?

• A.Assign LUN 0 to the boot LUN
• B.Enable the I/O elevator
• C.Set the execution throttle to 35025
• D.Set the LUN queue depth to 64

A company's storage administration team wants to receive e-mail notifications when the XtremlO cluster detects an issue of major severity. The administration team hassuccessfully configured and tested the e-mail server in the XtremlO web interface. However, the e-mail server is not receiving the expected notifications when major severityissues appear.
What is the cause of this issue?

• A.Event handlers have not been defined
• B.Alert definitions have not been defined
• C.Private reports have not been defined
• D.ESRS must also be configured

A systems administrator is installing a new Microsoft Windows 2012 host and has granted access to a 2 TB LUN from XtremIO. Quick formatting of the XtremIO LUN takes muchlonger than expected.
What is causing this delay in the formatting process?

• A.VAAI is disabled
• B.UNMAP is enabled
• C.UNMAP is disabled
• D.LBA Block size is set to 4 kB

Refer to the Exhibit.
An XtremlO administrator is asked to provide a copy of a 25 TiB database to a group of users. Each user needs to have their own copy of the database in order to perform a variety of manipulations on the data. This process needs to be repeated every day of the week. The administrator is concerned about the time it will take to make the initial copy of the database and is investigating the use of snapshots of snapshots.
How does each snapshot impact its ancestor?

• A.Each first write to each snapshot will trigger a COFW from its ancestor
• B.Each first write to a block of the production volume will trigger a COFW to each child snapshot
• C.Each first access to each snapshot will trigger a COFA from its ancestor
• D.Each snapshot can be considered a unique volume and has no impact
  on its ancestor

When using the Microsoft VSS Framework with an XtremlO cluster to manage snapshot backups, what is the correct sequence of steps to create a Windows volume backup?

正解：

Explanation:
The correct sequence of steps to create a Windows volume backup using the Microsoft VSS Framework with an XtremIO cluster is:
* Requestor interacts with the VSS service to start the backup
* VSS service sends a Freeze request to the Writer
* Provider creates an XVC of the file system and exposes the volume to the host
* VSS service sends a Thaw request to the Writer
* Requestor uses the XVC to back up the content of the volume
This sequence ensures that the backup is consistent and data integrity is maintained throughout the process.
