Actual exam question for LPI's 102-500 exam

Question #: 104
Topic #: 3

[All 102-500 Questions]

Which of the following find commands will print out a list of files owned by root and with the SUID bit set in /usr?

Afind /usr -uid 0 -perm +4000

Bfind -user root +mode +s /usr

Cfind -type suid -username root -d /usr

Dfind /usr -ls \*s\* -u root

Efind /usr -suid -perm +4000

Show Suggested Answer

Suggested Answer: A

This command will find all the files in the /usr directory that have the user ID (UID) of 0, which is the root user, and have the permission of 4000, which is the SUID bit. The SUID bit allows the file to be executed with the privileges of the file owner, regardless of who runs it. The -uid option tests for a specific UID, and the -perm option tests for a specific permission. The + sign before the permission means that at least those bits are set; the - sign means that exactly those bits are set. The other options are either invalid or do not match the criteria.Reference:

C is just confusing, not sure what they were thinking.

Wait, can you really use +4000 like that? Seems off.

I remember that the SUID bit is important, but I can't recall if -suid is the right flag in option E. It feels a bit off to me.

I practiced a similar question where we had to find files by user and permissions. I think the syntax in option B is off, though.

I'm not entirely sure, but I feel like the SUID bit is represented by +4000 in the permissions. Maybe option E is correct?

I think option A looks familiar; I remember it uses -uid for user ID, which should be 0 for root.

I've got this! The key is to use the -uid and -perm options to find the files owned by root with the SUID bit set. I'm pretty confident that option A is the right answer.

Ah, this is a tricky one. I'm not familiar with all the different find command options, so I'll need to review my notes and try to figure out the correct syntax.

Okay, let's see. I know I need to look for files owned by root with the SUID bit set in the /usr directory. I think option A might be the right one, but I'll double-check the syntax just to be sure.

Hmm, I'm not too sure about this. The different options for the find command are a bit confusing to me. I'll need to think this through carefully.

Option D is the way to go. The \*s\* pattern will definitely find all the SUID files, right? *winks*

The correct answer is A. The find command with the -uid 0 and -perm +4000 options will list files owned by root with the SUID bit set.
