I hope the smiley means you aren't serious. Let me pose some CS
questions, which I swear are off the top of my head. In all
fairness, I'm not sure if some of these will be advanced
undergraduate or graduate level, but we have been talking about CCIE
vs. PhD... I have tried to select questions that bear on real
networks.
CS-programming.

hierarchical linked list?

exponential, fractal, and Erlang B and C pdf's for both interarrival
and service time.

IV,
LISP, PROLOG, Pascal, C, Ada, C++ and SQL languages

monomorphism.

Differentiate between abstract syntax, operational semantics, and
transfer
syntax.
CS-operating systems

relationships to operating systems.

garbage collection.

processors, including the context switching issues.
