A storage administrator is tasked with creating a DR solution for block and file storage resources on a Dell EMC Unity 650F system at a primary production site. The company has two other campus locations.
Campus A is located 50 km away and has a Dell EMC Unity 400 Hybrid system. Campus B is located 200 km away and has a Dell EMC UnityVSA system.
What should the storage administrator do to provide the best protection of storage resources while meeting recommended latency levels?

1. A. Replicate block storage resources synchronously to Campus AReplicate file storage resources asynchronously to Campus B
2. B. Replicate block storage resources synchronously to Campus AReplicate file storage resources synchronously to Campus A
3. C. Replicate block storage resources asynchronously to Campus AReplicate file storage resources synchronously to Campus A
4. D. Replicate block storage resources asynchronously to Campus BReplicate file storage resources asynchronously to Campus A

Correct Answer: C

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

1. A. File Size
2. B. Blocks
3. C. User Quotas
4. 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.
