Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
esxcli storage core adapter rescan --all
Why this is correct
This command rescans all storage adapters on the ESXi host, refreshing paths to Fibre Channel, FCoE, and iSCSI targets.
- ✗
esxcli storage filesystem mount
Why it's wrong here
This mounts existing filesystems rather than rescanning host adapters for new paths.
- ✗
esxcli vsan cluster refresh
Why it's wrong here
This refreshes vSAN cluster state, unrelated to standard software iSCSI target discovery.
- ✗
esxcli network ip connection list
Why it's wrong here
This lists active TCP/IP connections, not storage adapters.
