Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
test dns-server [hostname]
Why it's wrong here
This is not a valid PAN-OS operational command.
✗
nslookup target [hostname]
Why it's wrong here
PAN-OS CLI does not use an 'nslookup target' command syntax; ping host handles DNS resolution testing.
✓
ping host [hostname]
Why this is correct
The 'ping host' command resolves the hostname via DNS and initiates ICMP echo requests.
✗
show dns-cache
Why it's wrong here
This command displays cached DNS records, but does not actively test live resolution.
