In this question we are required to redistribute only the default route from one EIGRP domain to another.
Obviously the default route in the route table is 0.0.0.0/0
If you want to match this route completely via ACL then we need
"access-list 100 permit ip 0.0.0.0 0.0.0.0    0.0.0.0 0.0.0.0" (This is an answer choice but is not chosen as the correct answer)
I have tried this in a lab and confirmed that it works as expected.

The above could also have been written as:
"access-list 100 permit ip host 0.0.0.0 host 0.0.0.0"

The answer that has been selected as correct  is "access 100 permit any host 0.0.0.0"
which means permit any route whose length is 0.
This did work in my lab but I think it's not the best answer.

Actually another answer choice "access-list 100 permit 100 ip host 0.0.0.0 any" also worked in my lab.
- permit prefix 0.0.0.0 on any length??

Please explain why the answer provided by h2p "access-list 100 permit ip any host 0.0.0.0" is the best answer compared with all the other answers.

thanks,

Here's an OSPF topology question which answer I don't understand.  Based on the "debug ip ospf events" command we see an area mismatch.  The topology indicates that Router C has both interfaces in Area 0.  Router A & Router B are both ABRs and it would seem that to resolve the issue you would place both routers E0/0 interfaces in Area 0.  But the correct answer is "Configure the E0/1 interfaces of router A and router B to be in area 0."  It seems to me that would cause a discontiguous Area 0 link.

Admin or Forum:

can you please explain the answer to question QID:RTE217?
This a question about redistribution between RIPV2 and OSPF (and vice-versa) and avoiding routing loops.
I think what needs to be done is to make sure that the routes advertised from OSPF to RIP and not advertized back from RIP to OSPF.

However, I do not understand how the the access-list with a deny clause works with the route-map with a deny clause.

I think the answer is not correct.

we need to stop 10.1.1.0 from being redistributed from RIP back to OSPF

stated answer:
   access-list 15 deny 10.1.1.0   0.0.0.63
   access-list 15 permit any  <-------

The above ACL will pass  to the route-map shown below all routes except 10.1.1.0
However the deny clause in the route-map will block all these routes from being redistributed - not the outcome be are looking for.

   route-map redis-rip deny 10
   match ip address 15

If you keep the ACL as-is, that is the ACL will pass all the routes that can be redistributed, then the route-map needs just one block:

route-map redis permit 10
match ip address 15.

"The route-map redis permit 20" is not needed.


(: all previous how2pass exams I had used had very good answer explanations. This 642-902 how2pass exam has a very high number of unexplained answers.

This is similar to QID:RTE235.  The correct answer is "The interface tunnel configuration is not correct." I cannot find what is wrong with the int tunnel 0 config.  There is no explanation.

The answer is "The crypto isakmp configuration is not correct:.  However this question comes without an explanation.  Also I didn't think that IPSec questions would be on the ROUTE exam since the topic isn't covered extensively in the curriculum.  GRE is covered so I expected the answer to be GRE related but the correct answer appears to be IPSec related.

I'm not sure why route 10.10.10.64/26 would be the only route redistributed into the OSPF area. 

Hang on...I think I see now.  That is an EIGRP route.  The other two routes are directly connected and therefore do not need redistribution, correct?

I took the ROUTE 642-902 test today.  But Failed!!

All the multiple questions are accurate from how2pass however LAB Simulations is NOT!!  I never across OSPF or EIGRP LAB question.

They had Ipv6 OSPF Lab and BGP lab questions.....they had one more...unfortunately I ran out of time to figure it out. They give you 2 hours. 52 questions.  I ran across 3 simulation labs that is not listed in how2pass ROUTE 642-902  Testlet/Simlet/Scenario Questions

The LAB question was actually about Ipv6 OSPF LAB Scenario where they have 4 routers connected with 3 different OSPF areas and I needed to figure it out why router 1 is not communicating with router 4. And the other LAB scenario for the next one was, " Customer has private IP MPLS, and has one router connected to two different eBGP HTTP connections. Question was  "How do you configure your router to specific BGP HTTP connection line without configuring static or summary routes?"  The
OSPF and the EIGRP SimLab never came up on the test.

Please provide new LAB test

I am interested in signing-up again for the CCNP ROUTE/SWITCH/TSHOOT tests with how2pass.  I would like a definitive statement from the site admin on what the current state is on how2pass's exam materials, how accurate they are, and how complete.

I have used how2pass a couple of time in the past to re-certify my CCNA and I would like to do the same for my CCNP, however I can not risk failing a test by studying with inaccurate or incomplete materials.

Please let me know the current accuracy and completeness of the questions/answers, Labs, Testlets, and simulations.  Thank you in advance for everything.
