NEW QUESTION # 103
What is the default file system quota policy on the Dell EMC Unity XT storage array?
- A. Tree Quotas
- B. File Size
- C. User Quotas
- D. Blocks
Answer: B
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 # 120
A Unity 400 system has Data at Rest Encryption licensed and enabled. Which operation(s) must be performed from the Unisphere Settings window to ensure the system is still operational after SP replacements?
- A. Download Audit Log
- B. Backup Keystore File
- C. Download Checksum
- D. Download Audit Log and Checksum
Answer: B
Explanation:
Explanation/Reference:
The keystore is tied to the storage processors, so care must be taken when performing service operations in order to preserve the encryption keys. In the event that the chassis and both storage processors need to be replaced, both storage processors should not be replaced at the same time. Instead, the chassis replacement should be followed while retaining one SP until the array is back online before replacing the second SP. In the case that storage processors have already been replaced at the same time and the keystore was lost, the keystore may be restored from an external backup.

NEW QUESTION # 121
What is the correct sequence of steps taken by the storage array when an AC power failure is detected?
Answer:
Explanation:
Explanation:
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.
