I feel like D) krb5p could be right too, but it adds extra security.

I think the answer is C) krb5. It's the standard for NFS v4.1.

Wait, is krb5p really not an option here? That’s surprising!

I believe krb5 is the right answer, but I should double-check if there are specific requirements for vSAN File services.

I’m a bit confused about the differences between krb5i and krb5p. I feel like I might have mixed them up in my notes.

I remember practicing a similar question, and I think krb5 is the most common choice for Kerberos with NFS.

I think we discussed that for NFS v4.1, we typically use krb5, but I'm not entirely sure if there are exceptions.
