Exam 200-301 topic 1 question 395 discussion

D probaly would is right too. If you gonna use OSPF you have more Routing overhead in your network. If its already implemented you can reduce the overhead by building different areas. All in all it increases the overhead. Answers by Question 184 proofs it

D is incorrect because it doesn't increase, but it decrease the routing overhead

A - C - E are correct

It increases routing overhead on the network againist to EIGRP

A C & E are correct

A C and E are correct because that's how scalable OSPF is

i think d is incorrect in question 222: Which three describe the reasons large OSPF networks use a hierarchical design? answer b: to reduce routing overhead is correct

A is correct B wrong, this is related to ebgp C correct, it confines network instability to one area of the network, eg in a multi area network if there's a problem in area 1 it will only affect area 1 D possibly correct , as the network grows it has to update its routing table and broadcast lsa, update lsdb, using more cpu and memory resource but this does not describe ospf its a symptom E. Correct, the router will flood Lsa specifically in its own area not to other areas F. Wrong. It's not that much easier to configure than rip v2

I think ACE are right, the only doubt is B: It is used to route between autonomous systems OSPF actually can operate between different AS thru the ASBR but it was born as an INTERIOR Gateway Routing Protocol, so to operate inside one AS.
