What does the Stealth option do on a name server for a DNS Zone?

Show Suggested Answer Hide Answer
Suggested Answer: A

Comprehensive and Detailed In-Depth

Stealth option in NIOS DNS (Data Management > DNS > Zone > Name Servers):

A: ''Stealth'' hides the server from NS records in the zone file, making it authoritative but unlisted---useful for internal servers. Correct.

B: Zone transfers are controlled by ACLs, not Stealth. Incorrect.

C: Caching is unrelated---Stealth affects visibility, not function. Incorrect.

D: Response behavior isn't altered---still answers queries. Incorrect.

Practical Example: In an INE lab, set a stealth NS, verify NS record absence, and troubleshoot external visibility.

I bet the Stealth option would be great for a name server that's trying to avoid the paparazzi. Option D, you're the real MVP.

I believe the Stealth option only hides the NS records, not necessarily block outside queries.

Oh, I see. The Stealth option is for when the name server just wants to stay under the radar, not answering any pesky queries. Option D is the one!

Hmm, I thought the Stealth option was like a ninja mode for the name server. Guess I was wrong, option D is the way to go.

But wouldn't it also prevent the name server from responding to outside queries?

I agree with Sharmaine, that makes sense because it would hide the name server's identity.
