An administrator must choose between deploying a virtual witness or physical witness for a vSAN Stretched Cluster. The administrator eventually decides to use a virtual witness.
What is a benefit of selecting this approach?

A newly deployed vSAN cluster runs vSAN 7.0, and the vSAN cluster needs an integration with a third-party software solution. The software solution provides full app-level redundancy, and it runs on the vSAN Data Persistence platform.
The administrator configures vSAN Direct Configuration to integrate the third-party storage with vSAN and now needs to configure a storage policy to make sure the vSAN Direct storage is used by the vSAN Data Persistence platform third-party software solution.
