Question 1

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

AFile Size

BBlocks

CUser Quotas

DTree Quotas

Answer : A

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.
