Which of the following NFS mount options specifies whether a program using a file via an NFS connection should stop and wait for the server to come back online, if the host serving the exported file system is unavailable, or if it should report an error?

Show Suggested Answer Hide Answer
Suggested Answer: B

The hard or soft NFS mount options are used to specify whether a program using a file via an NFS connection should stop and wait (hard) for the server to come back online, if the host serving the exported file system is unavailable, or if it should report an error.

Answer A is incorrect. The intr NFS mount option allows NFS requests to be interrupted if the server goes down or cannot be reached.

Answer C is incorrect. The nfsvers=2 or nfsvers=3 NFS mount options are used to specify which version of the NFS protocol to use.

Answer D is incorrect. The fsid=num NFS mount option forces the file handle and file attributes settings on the wire to be num.

Wait, are you saying it can just report an error? That sounds risky!

I thought it was A, intr. Seems like a common misconception.

I don't recall "fsid" or "nfsvers" being related to waiting for the server; they seem more about versioning and identifiers.

I feel like "hard" means it will keep trying to connect, while "soft" will give an error after a timeout. I hope I remember that correctly!

I remember practicing a question about NFS options, and I think "intr" might allow interruptions, but it doesn't really specify waiting for the server.

I think the option that controls whether a program waits for the server is related to "hard" or "soft" mounts, but I'm not entirely sure which one it is.

Okay, I've got this. The key is that too much granularity, or too many specific data categories, will make the classification process difficult to manage and apply consistently. It could also create challenges in assigning ownership of the data.

Okay, let me see... Footprinting is about gathering information, so the answer is probably related to the target system. I'll go with B.

Hmm, I'm a bit unsure about this one. I know IDEA is a block cipher, but I can't recall the specific block and key sizes off the top of my head.
