EIGRP & OSPF Questions 2

ADMIN….. please explain the Q 4 ….. if you look at it technically all options are correct and all options would include the interface IP the is required .

i cant see any questions ??
i just see the answers

@cert… you are correct but best practice is to do an exact match when doing route advertisement, if not a summary route. So answer C has the most exact match to the interface as the wildcard is 0.0.0.0 requires the address to match exactly.

The origina configuration did not match because the range was 20.0.x.x where x.x is any number but the interface had 20.1.x.x instead.

Question 4
20.1.1.2 0.0.255.255 will start the process on all interfaces and R2 can have other interfaces that are not part of area 0
20.1.1.2 255.255.0.0 wrong syntax, but router will reverse it and the result will be same as the above
20.1.1.2 0.0.0.0 will start the process with area 0 on this particular interface
20.1.1.2 255.255.255.255 will start the process with area 0 on ALL interfaces – same 0.0.0.0 255.255.255.255 statement as on R1

Hello Team,

Are the dumps still valid ?

Question 4:

I ran all the answers through my GNS3 simulation and A-D formed neighborships. E did not. So what is the best answer? Please explain why? See copied and pasted config and output for sim details:

R1#show run | b router
router ospf 1

Answer A:

R2(config)#router ospf 2
R2(config-router)#no network 20.1.1.2 0.0.255.255 area 0
R2(config-router)#no network 20.1.1.2 0.0.255.255 area 0
R2(config-router)#exit
R2(config)#router ospf 2
R2(config-router)#network 20.1.1.2 0.0.255.255 area 0
R2(config-router)#do show ip ospf neighbor

Answer B:

R2(config-router)#network 20.1.1.2 255.255.255.255 area 0
R2(config-router)#do show ip ospf neighbor

R2(config-router)#no network 20.1.1.2 255.255.255.255 area 0

Answer C:

R2(config)#router ospf 2
R2(config-router)#do show ip ospf neighbor
R2(config-router)#network 20.1.1.2 0.0.0.0 area 0
R2(config-router)#do show ip ospf neighbor

Answer D:

R2(config-router)#network 20.1.1.2 255.255.0.0. area 0

Answer E:

R2(config-router)#network 20.1.1.0 0.0.0.0 area 0
R2(config-router)#do show ip ospf neigh
% Ambiguous command: “do show ip ospf neigh”
R2(config-router)#do show ip ospf neighbor
R2(config-router)#do show ip ospf neighbor
R2(config-router)#

Please correct the answer and explanation for Q4. There are so many errors there!

Can someone please let me know what is the correct answer for Q4?

From what I understand , command ‘network 20.1.1.2 0.0.0.0 area 0’ would just specify the single host of 20.1.1.2 as its a wildcard mask.

I feel network 20.1.1.2 0.0.255.255 area 0 is the correct answer.

Can @digitaltut so someone who has taken the test clarify this

Pass4 surexams.com exam dumps helped me achieve a score of 92%.

Q4

Answer is C.

This question is stupid and most likely it isn’t even in the exam, as A and B also work. These stupid questions are just wasting everyone’s time and should be removed from this site.

C is the best answer, but the explanation is wrong. It should read “Therefore we have to use the command “network 20.1.1.2 0.0.0.0 area 0” to turn on OSPF on this interface.”

Answer is C
The rest of option are wrong
C. network 20.1.1.2 0.0.0.0 area 0 > 0.0.0.0 means match all the octets on the left …

please share question i just see answeres am preparing for Encor next week

please advise on the lab what are we support to do in the exam day do we do real troubleshotting or we have multiple choise for the lab
