Question

To authenticate using Kerberos, you must add the Kerberos user principals to MongoDB to the _________ database.

(a) $internal

(b) $external

(c) $extern

(d) None of the mentioned

I have been asked this question during an internship interview.

My question is from Kerberos Authentication in section Production Checklist, Security Concepts and Network Security of MongoDB

Answer 1

Right option is (b) $external

The best I can explain: For every user you want to authenticate using Kerberos, you must create a corresponding user in MongoDB in the $external database.
