[Cisspstudy] Encryption methods

I think block and streams are two modes of symmetric encryption. While asymmetric and symmetric are two methods of encryption.
Where can I find additional information on quantitative risk analysis? The CBK is vague and Shon's AIO seems to focus more on it but she brought up the total risk equation. I am looking for a more concised example like calculate ALE of a system that is only used 20% of the year.

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.

Yes, a poor question. However, it is part of the ISC2 game. I had many
questions that could have gone either way. It wouldn't surprise me if
some questions are like this one on the exam to mess with you.
Purposely adding to the stress of the exam. Also, a percetage of the
questions are for "research purposes".

Greetings,
Block ciphers & Stream-Based are the two methods of cryptography
Symmetric & Asymmetric are two forms of cryptography

As far as I can say as for as Shon is concerned 'methods' refers to symmetric vs. asymmentric
Official ISC2 guide - Page 227
"Methods of Cryptography"
Here for "methods" the author refers to block vs stream ciphers

I am using Transcender V 3.7.0 Build 3/3/2006. I did not see an option to
pull down updates.

Question: What is the version of the exam that you use ? Before you
tried the Transcender practice exams, did you check to see if there is
any updates?
