Question

Which of the following code is returned when a MongoDB application cannot open a file?

(a) 45

(b) 20

(c) 47

(d) 100

I had been asked this question at a job interview.

My question is based upon Exit Codes and Statuses topic in chapter Production Checklist, Security Concepts and Network Security of MongoDB

Answer 1

Right answer is (a) 45

The best I can explain: 45 is returned when a MongoDB application cannot open a file or cannot obtain a lock on a file.
