Show Suggested 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?

The Stealth option prevents the name server from responding to outside queries, so option D is the correct answer.

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