Question 1

Explanation

The subnet of Fa0/0 of R2 is 172.16.109.0/26 (range from 172.16.109.0 to 172.16.109.63) which covers the subnet of S0/1 interface 172.16.109.4/30 so in fact the answer C is not correct. But from the output of the “show ip interface brief” command we see both Fa0/0 and S0/1 interfaces’ statuses are ‘up/up’ -> they are working normally. So we think there is a typo in the subnet mask of Fa0/0. It should not be ‘/26’ but longer one, ‘/28’, for example. So you should still choose answer C in this question.

Question 2

Explanation

The “Operational Mode” is “static access” so this port is currently in access mode.

Question 3

Explanation

Both routers must use the same password for CHAP to authentication.

Question 4

Explanation

From the output we see the Serial0/0 of RouterA is in “status up/protocol down” state which indicates a Layer 2 problem so the problem can be:

+ Keepalives mismatch
+ Encapsulation mismatch
+ Clocking problem

Question 5

Question 6

Question 7

Explanation

Now let’s find out the range of the networks on serial link:

For the network 192.168.1.62/27:

Increment: 32
Network address: 192.168.1.32
Broadcast address: 192.168.1.63

For the network 192.168.1.65/27:

Increment: 32
Network address: 192.168.1.64
Broadcast address: 192.168.1.95

-> These two IP addresses don’t belong to the same network and they can’t see each other -> D is the correct answer.

Question 8

Question 9

Explanation

The “System Configuration Dialog” appears only when no startup configuration file is found. The network administrator has made a mistake because the command “copy startup-config running-config” will copy the startup config (which is empty) over the running config (which is configured by the administrator). So everything configured was deleted.

Note: We can tell the router to ignore the start-up configuration on the next reload by setting the register to 0×2142. This will make the “System Configuration Dialog” appear at the next reload.

    I passed with 941/1000. 52 questions. OSPF, EIGRP, ACL 1 /2. Few new questions. Thanks to 9tut.com. dumps valid 95%. Pls guys you should be careful with answering the labs because the answers were actually different even though the topology and questions were the same. Try as much as possible to be well familiar with your hands-on lab. Good luck people. Over to CCNP. Took the exam on 7th of Nov 2015.

    Q4: ‘Interface S0/0 on RouterB is administratively down’ is also a good answer…

  18. rb
    April 4th, 2016

    @ccii .. Int s0/0 has not been assigned any IP addresses. So, question is only talking about first 2 interfaces.Mentioned above is the right answer.

  19. rb

    For Q:6, on a serial link, both connected interfaces have to be in the same subnet in order to communicate (“see each other”).

    Passed the CCNA Finally! I had to take the CCNA twice, as I failed on my first attempt. However for my second, I used the e8ay dump to study the update that happened for the CCNA and passed the exam finally :D All Questions came from the dump. The e8ay dump has a total of 142 questions (58 + 84 updated questions) and the 4 variations of the ACL sims. I didn’t check out the study materials here but they seem helpful stated from other comments.

    Information to the exam:

    54 MC Questions
    1 ACL simulation
    1 EIGRP TSHOOT Simlet
    1 OSPF TShoot Simlet
    1 RIPv2 Simlet
    Total of 58 questions.

    If you would like to check out the materials I used, here you go:

    e8ay.com/itm/322336782526? (change the “8” to a “b”)

    Good Luck!

    Overall there are many websites of Cisco 200-125. But I’m recommend to braindumps4it of Cisco https://www.braindumps4it.com/braindumps-200-125.html Exam. Once ready, you can easily pass it exam in first attempt.
