Discuss ISC2 CSSLP Exam Topic 9 Question 102

Which of the following methods determines the principle name of the current user and returns the jav

a.security.Principal object in the HttpServletRequest interface?

AgetUserPrincipal()

BisUserInRole()

CgetRemoteUser()

DgetCallerPrincipal()

Suggested Answer: A

The getUserPrincipal() method determines the principle name of the current user and returns the java.security.Principal object. The

java.security.Principal object contains the remote user name. The value of the getUserPrincipal() method returns null if no user is

authenticated.

Answer C is incorrect. The getRemoteUser() method returns the user name that is used for the client authentication. The value of the

getRemoteUser() method returns null if no user is authenticated.

Answer B is incorrect. The isUserInRole() method determines whether the remote user is granted a specified user role. The value of the

isUserInRole() method returns true if the remote user is granted the specified user role; otherwise it returns false.

Answer D is incorrect. The getCallerPrincipal() method is used to identify a caller using a java.security.Principal object. It is not used in

the HttpServletRequest interface.

Wait, is it really A? I thought it could be D.

Emeline 10 months ago

I thought it was C, getRemoteUser()...

Merissa 10 months ago

A is the standard method for this!

Carmelina 10 months ago

A is correct, no doubt about it!

Brandon 11 months ago

It's definitely A, getUserPrincipal()!

Elly 11 months ago

getCallerPrincipal() seems like it could be the answer too, but I can't recall if it specifically relates to HttpServletRequest.

Marvel 11 months ago

I feel like isUserInRole() is more about checking permissions rather than getting the user's principal name.

Sanjuana 11 months ago

I remember practicing a question similar to this, and I think getRemoteUser() was mentioned, but it might not return a Principal object.

Frank 11 months ago

I think the method we're looking for is getUserPrincipal(), but I'm not entirely sure. It sounds familiar from our lectures.

Rosenda 12 months ago

I'm feeling a little lost on this one. I know the HttpServletRequest interface has some methods related to user authentication, but I'm not entirely sure which one would return the java.security.Principal object. I'll have to review my notes and try to narrow it down.

Lorrine 12 months ago

Okay, let me think this through. The question is asking about a method that returns the principal name of the current user, so I'm guessing it's either getUserPrincipal() or getCallerPrincipal(). I'll have to double-check the documentation to be sure.

Jolene 12 months ago

Hmm, I'm a bit unsure about this one. I know there are a few methods in the HttpServletRequest interface related to user authentication, but I can't quite remember which one specifically returns the java.security.Principal object.

This looks like a straightforward question about the HttpServletRequest interface. I'm pretty confident the answer is getUserPrincipal().

Mabel 1 year ago

I wonder if the exam question is trying to trick us with B) isUserInRole(). That's usually used to check if the user has a specific role, not to get the principal. A) is my pick.

I'm not sure, but I think C) getRemoteUser() might also be a possibility.

I agree, B) isUserInRole() is more for checking roles.

I think A) getUserPrincipal() is the correct method.

I believe it's D) getCallerPrincipal() because it sounds more official

Johnetta 1 year ago

I'm not sure, but I think it might be C) getRemoteUser()

Joni 1 year ago

D) getCallerPrincipal() sounds like it might be the answer, but I'm not sure if it's specific to the HttpServletRequest interface. I'll go with A) just to be safe.

I agree, I'll go with A) as well just to be safe.

I think A) getUserPrincipal() is the correct method to determine the principle name of the current user.

Deandrea 1 year ago

I agree with Mabel, getUserPrincipal() makes sense

Jaclyn 1 year ago

C) getRemoteUser() is a good option too, but it only returns the username, not the full Principal object. I think A) is the better choice.

Cecil 1 year ago

A) getUserPrincipal() seems like the correct answer here. It's the method that retrieves the java.security.Principal object, which represents the current user's identity.

Angella 1 year ago

↳ replying to Cecil

Yes, getUserPrincipal() is the right choice. It retrieves the current user's identity.

Alexis 1 year ago

↳ replying to Cecil

I think the correct method is getUserPrincipal(). It returns the java.security.Principal object.

Mabel 1 year ago

I think the answer is A) getUserPrincipal()
