Point is, what if you have a question that goes like:

What are the most important encryption methods:

1. symmetric, asymmetric

2. block, stream

It is a BAD question I know but still I am sure I rember I had a question
like this one somewhere.

Moreover, is this the likely to be the level of trickery the CISSP can
present ? Unfortunately I don't know and this is the reason why I am
scratching my head everytime I find inconsistences.
