What is the minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring)?
In a vSAN stretched cluster with dual-site mirroring and local protection using a storage policy of 1 failure - RAID-1 (Mirroring), you need a minimum of 6 hosts to provide data redundancy.
This setup requires two copies (mirrors) of the data in each site (dual-site mirroring) and one additional copy for local protection (RAID-1 mirroring). So, you'll have three copies of your data in total. In a stretched cluster, the minimum configuration would typically involve at least 2 hosts in each site (for fault tolerance in the two sites) and an additional 2 hosts to ensure local protection, making it a total of 6 hosts.
So, the correct answer is:
D. 6 hosts
