Some of the more obscure or hidden stuffs are BGP next hop
reachablity, for example, that BGP router A segment connecting to BBx
router which is not advertised to internal network via IGP. You need
the next-hop-self to fix the problem else any iBGP router receiving
the updates from router A will not install those BGP routes.
Another one is where to use Route Reflector, draw on a seperate BGP
diagram where are those iBGP and eBGP peerings. It can be useful to
keep seperate IGP and BGP drawings.
If you start to see the questions asking for BGP AS 65xxx, chances
are, either there will be confederation BGPs or some point in time,
you need to do a remove private AS along the way.
I think most of the "Spot the Issues" thinking is acquired through
experience and only "Practise and more Practise" in any vendors
workbooks will help you to identify those evil little hiccups hidden
ahead of you.
You will sometime find yourself very careless in overlooking some
issues if you read the questions blindly without running through your
"CPU" what are the implications, etc.
