An vSAN administrator is relying on vSAN Stretched Clusters to protect against entire-site failures. How is this protection accomplished?

Question

Options

• ABy configuring data locality
• BBy placing redundant components at both sites
• CBy synchronizing virtual machine data from the witness site
• DBy using asynchronous data transfer

Explanation

Each site in the stretched cluster is configured as a fault domain. Fault domains are used to spread redundancy components across servers. In a traditional vSAN cluster, redundant components are spread across servers in separate computing racks, and as a result, can tolerate rack failures, cache and capacity device failures, network device failures, and power failures. When used in a stretched cluster, fault domains spread redundancy components across sites, and therefore can tolerate the failure of an entire data site. The minimum number of hosts in a stretched cluster is three, one host in each data site plus the witness host in the witness site. The maximum number of hosts in a stretched cluster is 31, fifteen hosts in each data site plus the witness host in the witness site.
