Failed my CCNP Route by 1 question 780/790

Very good point about the RFC... on a Cisco exam it is ALWAYS important to read the Cisco version of things!

Not to mention the errors in the exam, like taking asking a generic question about a Type 4 LSA when there is no Type 4 LSA and they mean Type 3 LSA because there is no ASBR.

Wait, what? LSA goes all the way to 11. https://en.wikipedia.org/wiki/Link-state_advertisement

Or did you mean no Type 4 in the problem?

No... there was no Type 4 LSA, they meant a Type 3 Summary LSA. This was an ABR, and there was no ASBR for the ABR to generate the message to the other areas.

I never use OSPF for work, so it is not my strongest subject.  But Type-4 is for routers that are redistributing into OSPF from another protocol, right?  So even if a router isn't running a second protocol like RIP or EIGRP, what about a router redistributing static or connected routes?  It is the redistribute command that signals the OSPF process to start sending out Type-4 LSA's, right?  So could one of the routers have been redistributing static and/or connected?

Yes it will create a Type 4 LSA. What I am saying is, it there was NO summary ASB in the ospf database. Yet it was asking for a type 4 lsa

Well I'm fresh out of ideas. 

Could it have been one of those weird minutia type questions where they ask for X but you are supposed to know it was converted to Y during process Z?  I've noticed they have a way of asking round about/purposely misleading questions that require a lot of rereading to decipher what they are really asking LOL.
