Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a new virtual machine on the host.
Why it's wrong here
Creating a VM does not trigger storage path discovery.
- ✓
Rescan the storage adapters on the ESXi host.
Why this is correct
Rescanning storage adapters prompts the host to query the storage fabric for newly added LUNs or paths.
- ✗
Reboot the vCenter Server appliance.
Why it's wrong here
vCenter does not manage direct host storage discovery; rescanning the host is required.
- ✗
Restart the CIM monitoring service.
Why it's wrong here
CIM monitors hardware health, not storage LUN discovery.
