Passed 3/5 RHCA: EX333 Security Network Services

I would probably rate EX333 as the most difficult exam among the 3 exams I have passed, Why  is it so difficult?

1. The exam objectives are related: for example, Kerberos depends on NIS, without a working NIS, you are doomed.

2. The exam is broken into morning section and afternoon section, You won’t pass the exam  if either section fails. but  you are still allowed to sit for the afternoon section despite  the result of morning section.

My blog post for EX333 study notes:

Authenticate BIND zone transfer with TSIG key

Setup Postfix SMTP password authentication with SASL
