A site administrator has determined that the site needs to upgrade all vSAN clusters to 7.0 U1. The vSAN administrator wishes to complete the update in the shortest amount of time possible. All virtual machines are assigned a storage policy where the "Failures to tolerate" is set to one or higher.
Which strategy should be used to achieve this goal?

An administrator wants to check the vSAN cluster health during the maintenance window while vCenter Server is offline.
What are two ways to complete this task? (Choose two.)

A host in the cluster experiences a permanent NIC failure, and the replacement part will not arrive until the next morning. The administrator needs to ensure the availability of the production workload at all times.
Which step should be taken by the administrator to meet this goal?

The cluster level backend IOPS performance graph shows a higher-than-average number of IOPS for back-end storage.
What is a possible reason for this situation?

A remote location was configured with Cloud Native Storage. When the administrator put the host in maintenance mode to perform monthly patching, the File Server Health check was triggered.
Which action, if any, should the administrator take to resolve the issue?
