• Question 4:

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

  A. File Size

  B. Blocks

  C. User Quotas

  D. Tree Quotas

  Correct 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.

• Question 9:

  What remote service is required to enable Remote Logging in the Dell EMC Unity XT system?

  A. SNMPv3

  B. Syslog

  C. SNMPv2

  D. Unisphere agent

  Correct Answer: B

  Before configuring remote logging for a storage system, you must configure each remote system to receive logging messages from the storage system. A root/administrator on the receiving computer can configure the remote syslog server or rsyslog server to receive log information by editing the syslog server or rsyslog server configuration file (syslogng.conf or rsyslog.conf) on the remote system.
