In all seriousness, the biggest things you can do here are to analyze
every show command and debug option for the major areas of the exam:
RIPv2
EIGRP
BGP
OSPF
WAN topics (Frame Relay, PPP, etc)
Basic security stuff
QoS
Just use the question mark and take them one by one, setting up
scenarios on your own as you go. Continually make yourself demonstrate
with show and debug commands exactly what the protocols are doing. For
each of the major topics you should be able to instantly think of a
couple of different ways of verifying major events:
How do I know if I've gotten the neighbor state I want?
How do I figure out what prefixes I'm advertising?
How do I figure out who sent me a prefix?
How do I determine why I'm choosing path A instead of path B?
How do I know if something's getting dropped due to a L2, L3, or L4
issue?
Etc.
Another thing I try to do habitually is to ask myself (especially with
more obscure diagnostics) "why did the developers put this command in?"
In a lot of cases, they probably either had a request from TAC, or a
customer feature request, or an escalated internal issue that made
somebody think "hmm, it sure would be nice if we had a command that did
X." I try to figure out what those situations might have been--this will
give you insights into the protocols that you might otherwise have
missed.
Another question to ask yourself is "why did they choose to do it this
way, when another way might have worked too?" Case in point: when I was
first learning about the internals of routing protocols, it really
bugged me that you use the "network" command to enable routing on an
interface level. Why not do it on the interface instead? In some
protocols you can: IS-IS, or in recent IOS versions, OSPF. Or in IPv6.
Or IPX, for that matter. This is a fairly simple question and I'm sure
you can think of lots of reasons to do it one way or another, but it's
an example of an exercise you can go through to think about the
protocols in different ways.

Subject: BAD Santa,
Hello
One of my biggest problem is been able to verify my answers, (in a
timely manner)
-Is there a link, or book etc, that would help with this issue?
-If I had to purchase 2 workbooks? Which ones would you recommended
- I just did my lab in RTP, lets just say santa was NOT good to me
Thanks for ALL suggestions
