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.

Surprised to hear that! I always thought it was about responding to outside queries.

I thought the Stealth option had to do with caching responses, but I could be mixing it up with another topic.

I’m leaning towards option D, where it prevents the name server from responding to outside queries. I think that was mentioned in a lecture.

I remember studying that the Stealth option might stop NS records from being added automatically. It’s a bit fuzzy, though.

I think the Stealth option is related to preventing automatic zone transfers, but I'm not entirely sure. It feels like I've seen something similar in practice questions.

I've got a good feeling about B. Preventing automatic zone transfers seems like the most logical explanation for the Stealth option.

I'm not totally sure about this one. The options all sound plausible, but I'll have to eliminate the ones that don't seem to fit the description of "Stealth".

The Stealth option sounds like it has to do with security or privacy for the name server. I'm leaning towards B or D.

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.
