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 110
Which task must be performed on the storage system in order to access a file system read/write snapshot?
- A. Connect to the NFS/SMB share of the snapshot
- B. Perform the snapshot "Attach to Host" operation
- C. Configure the NFS/SMB share to the file system snapshot
- D. Configure Host Access to the LUN snapshots
Answer: C
Explanation:
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.
