The Question “How many directories must MongoDB have access to?” gives correct answer as 3
/data/db, /var/log, /var/pki… The question doesn’t specify what kind of access…
Unless otherwise specified, I believe it’s not incorrect to assume the Parent folder of a Child folder (all 3 here) should at least have execute access permission in place for the process to be able to access the child folder(s). in that case we should also consider the parent folder (/data, /var) access permissions for this answer, which should be 3+2=5; But this isn’t present as an option.
Requesting co-ordinators and other respected members to kindly advise on this.
