Which VM storage policy rule category ensures all VMs for a department are on the same datastore?

A vSphere administrator has the privilege Content library > Add library item on the vCenter object, but is unable to add items to a local content library.
How would the vSphere administrator correct this?

When enabled, what ensures only signed drivers can load into a virtual machine?

A VM is experiencing inconsistent network connectivity between two ESXi hosts connecting to the same physical switches. The effect of the inconsistency is this:
vMotion from host 1 to host 2, network connection is down
vMotion from host 2 to host 1, network connection is up
vMotion from host 1 to host 2, network connection is up
The vSphere administrator wants to ensure the physical switches connecting to the ESXi are configured correctly.
How can this be accomplished?

An administrator suspects poor VM performance. The administrator runs esxtopand sees the following output from the CPU and memory screens:
6:48:19pm up 4:22, 528 worlds, 8 VMs, 16 vCPUs, CPU load average: 0.26, 0.36,
0.16
VMKMEM/MB: 8151 managed: 407 minfree, 3055 rsvd, 5095 ursvd, high state What can the administrator conclude from this output?
