CCNA SSPO Review Questions - Set 1

The quiz is located at https://learningnetwork.cisco.com/docs/DOC-7318

Topics I need to review:
NGN Architectural Layer
Service Exchange Framework
ITIL
eTOM

For NGN Architecture, there's an ASR9k link which seems the most relevant:
http://cisco.biz/en/US/prod/collateral/routers/ps9853/solution_overview_c22-501795.html
I'll be reading this many times over.

Service Exchange Framework is here:

Cisco's Introduction to eTOM:
http://www.cisco.com/en/US/technologies/collateral/tk869/tk769/white_paper_c11-541448.html

As for ITIL, there's a comparison to eTOM on the above link. We'll see if I need to know more than that.
