VMware introduced Stretch Clusters in vSAN 6.6. Which of the following is NOT true about Stretch Clusters?

  • Stretched clusters use fault domains to provide redundancy and failure protection across sites.

VMware introduced Stretch Clusters in vSAN 6.6. Which of the following is NOT true about Stretch Clusters?

EXPLANATION

The witness host cannot run VMs.
The witness host can be a physical host or an ESXi host running inside a VM. The VM witness host does not provide other types of functionality, such as storing or running VMs.
Multiple witness hosts can run as VMs on a single physical server. For patching and basic networking and monitoring configuration, the VM witness host works in the same way as a typical ESXi host. You can manage it with vCenter Server, patch it and update it by using esxcli or vSphere Update Manager, and monitor it with standard tools that interact with ESXi hosts.
