10 thoughts on “Which ospf area prevent LSA type 4, LSA type 5?”
cisco is giving this shitty question because there is a higher probability that you fail it, and then you pay for another exam.. IT IS ALL ABOUT BUSINESS, why they have no effort to improve their practical labs on exam? everyone knows that they could, but they dont want to, many things are not fixed there,… BECAUSE THIS IS A PART OF THEIR BUSINESS!!!!
Im wondering how will look like their new certifications after 23th February …
CCNP Entreprise should be much more difficult and seems like networking will be end of life within 10yrs
The trend is going to NetOps, SysOps, all can be automated by API/Python.
Recommended not to take CCNP entreprise and wasting your money and time
If I recall well NSSA allows LSA 7 in the ASBR(redist. eigrp into ospf router), but 5 in the ABR (ie. any area 0 router). stub and totally stub, definetely allows only LSAs 1,2,3 and 1,2 anywehere.
correct question:
Which OSPF areas prevent LSA type 4, LSA type 5? ( choose two)
A. Not-so-stubby area
B. Total stubby area
C. Stubby area
D. Normal area
E. Backbone area
F. Not-so-stubby totally stub area
Stub No Type 5 AS-external LSA allowed, accepts only 1,2,3 but no 4
totaly stubby No Type 3, 4 or 5 LSAs allowed except the default summary route NSS, accepts only 1,2 and route 0.0.0.0
NSSA No Type 5 AS-external LSAs allowed, but ABR converts type 7 to type 5. It accepts type 3 and 4
totaly NSSA No Type 3, 4 or 5 LSAs except the default summary route, but ABR converts type 7 to type 5.
I think that NSSA is a good response too because it does not accept Type 4 and type 5

Jose is right. Question is incorrect in it’s entirety. Here is breakdown of Type 4 & Type 5 LSAs: https://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/13703-8.html#anc1
This question does not make sense .
answer agree with Jochen – all stub areas do not accept LSA type 4 and Type 5.
I would say A and C

Answer B-F.
ABC is correct but as José says the question is incorrect.
All kinds of stub areas prevents LSA 4 & 5.
So correct answer on José question is ABCEF

The good response is : B and C
Stub No Type 5 AS-external LSA allowed, accepts only 1,2,3 but no 4
totaly stubby No Type 3, 4 or 5 LSAs allowed except the default summary route NSS, accepts only 1,2 and route 0.0.0.0
NSSA No Type 5 AS-external LSAs allowed, but ABR converts type 7 to type 5. It accepts type 3 and 4
totaly NSSA No Type 3, 4 or 5 LSAs except the default summary route, but ABR converts type 7 to type 5.
I think that NSSA is a good response too because it does not accept Type 4 and type 5
