CCNA – IP Routing 2

April 15th, 2015 Go to comments

Question 1

Explanation

There are no dynamic routing protocols running on Coffee router, only a default route is configured to route all traffic to 172.19.22.2 but we don’t know about this network. The correct IP address should be the IP address on the interface of Tea router which is connected to Coffee router (maybe 172.18.22.2).

Question 2

Explanation

Maybe “the most direct path available” here means via R2 because it is directly connected with the Internet while the London path needs to go through R1. So we need a command to send traffic to R2 and the correct command is “ip route 0.0.0.0 0.0.0.0 172.16.100.2″.

Question 3

Question 4

Explanation

The destination IP address 10.1.5.65 belongs to 10.1.5.64/28, 10.1.5.64/29 & 10.1.5.64/27 subnets but the “longest prefix match” algorithm will choose the most specific subnet mask -> the prefix “/29″ will be chosen to route the packet. Therefore the next-hop should be 10.1.3.3 -> C is correct.

Question 5

Explanation

While transferring data through many different networks, the source and destination IP addresses are not changed. Only the source and destination MAC addresses are changed. So in this case Host A will use the IP address of Host C and the MAC address of E0 interface to send data. When the router receives this data, it replaces the source MAC address with it own E1 interface’s MAC address and replaces the destination MAC address with Host C’s MAC address before sending to Host C -> C and F are correct.

Question 6

Question 7

Question 8

Explanation

Host A knows host B is in another network so it will send the pings to its default gateway 192.168.6.1. Host A sends a broadcast frame asking the MAC address of 192.168.6.1. These information (IP and MAC address of the default gateway) is saved in its ARP cache for later use.

    @waqas: We had to move all the questions and answers out of 9tut because of copyrighted issues. We can only keep the explanation. You can download the questions and answers at: http://www.mediafire.com/view/2r1tai7xqa05qub/CCNAquestions_Jul_7_2015.pdf

    Q8 D is correct. I don’t think they would mix proxy-ARP into this basic question.

    Hello,

    Can you give more attention on q8?
    “Host A knows host B is in another network…” i think that host A doesnt know that, that know switch1 from mac table, am i wrong?

    Thank you all!

    question 8 After HostA pings HostB, which entry will be in the ARP cache of HostA to support this transmission? why answer d is correct and not answer A?

    could you give me more explanation abouth question 2

    A, B, E are false because a default route to the internet (which is what we are doing here) must have a netmask of 0.0.0.0.
    C 128.107.1.1 is probably the IP of the next hop in the Internet (i.e the ISP router) but here we need the next hop IP or the outgoing interface of Manchester router.
    D is false because 0.0.0.00.0:0:0 doesn’t exist
    F has a netmask of 0.0.0.0 and the good next hop -> correct.

    And about the direct path in the explanation was because there is 1 less serial link from Manchester to the internet via R2, and E1 cables are only 2Mb/s.

    According to Actual tests and Passleader for Q8 the answer is A and according to 9tut it is D. Can anyone confirm which is the right answer please????

    Q8, should the correct answer be A?

    anyone recently had question 8 in the exam and answered correctly ? I believe it to be answer d because it’s looking at the Arp cache. any other question like this if not mentioning arp cache would be answer a.

  22. Nashat Odeh

    q8 answer should be D, I test the enviroment and run the command from my PC ” arp -a”.

    What is the correct answer for q8? Has anybody seen this same quest on the exam which they have correctly marked according to the expectation of Cisco? Although I feel the explanation given suits best for option D to be the ans, I just wanna be sure as I am appearing for my exam next week..Any suggestions would be appreciated..

    CS
    I’ve studied many dumps question 8 some have A as the correct answer. some have D
    I’ve seen comments in 9tut someone who had score 1000 picked D
    I will choose D. ( If it’s not the same letter pick the ip of the default gateway ). this is due to comments about this info being in the Arp table. different than other similar questions. hopefully I will get this correct if I get the question in the exam

  25. ACL

    For Q8. Remember that as the packets reach a different subnet, the source and destination MAC address will change (but the IP address will remain the same). So host A will have a source MAC of fd86, destination MAC of 8916. As it goes to the serial link, the source and MAC address information will change and so forth. It will only know of the MAC of the e0 interface.

  26. ACL

    Correction. It should be the fa0/0 interface.

  27. ACL
    July 25th, 2016

    and the corresponding IP of fa0/0 is 192.168.6.1

  28. Tche

    The correct answer is D regarding question 8.

    At this time it seems like Movable Type is the best blogging platform available right now. from what I’ve read Is that what you are using on your blog? cagfckeacaadebdc

    About question 8:
    ICND1 100-101 states – page 113 – TCP/IP defines the Address Resolution Protocol (ARP) as the method by which any host or router on a LAN can dynamically learn the MAC address of another IP host or router on the same LAN. ARP defines a protocol that includes the ARP Request, which is a message that asks the simple request “if this is your IP address, please reply with your MAC address. ARP also defines the ARP Reply message, which indeed lists both the original IP address
    and the matching MAC address.
    That is why, A is the correct answer, the IP address listed on D, belongs to another LAN.

    About question 8: – disregard the previous message.
    ICND1 100-101 states – page 113 – TCP/IP defines the Address Resolution Protocol (ARP) as the method by which any host or router on a LAN can dynamically learn the MAC address of another IP host or router on the same LAN.
