Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 84

VxRail all-flash nodes have been deployed in a Stretched Cluster configuration. A storage policy has been configured as follows:

Site disaster tolerance - Dual site mirroring
Failures to tolerate - No data redundancy

What protection will a VMDK have with this storage policy?

Answer options

• A. RAID-1 cross-site - RAID-5 locally
• B. RAID-1 cross-site - No local protection
• C. RAID-1 cross-site - RAID-1 locally
• D. No cross-site protection - RAID-1 locally

Correct answer: C

Explanation

The correct answer is C because with dual-site mirroring, VMDKs have RAID-1 protection across sites, ensuring that data is mirrored. Additionally, since there is no data redundancy specified, local protection is also implemented as RAID-1, providing redundancy within the local site. The other options incorrectly describe the levels of protection based on the provided policy.
