CCNA – Operation 2

March 19th, 2015 Go to comments

Question 1

Explanation

Each interface on a router must be in a different network. If two interfaces are in the same network, the router will not accept it and show error when the administrator assigns it.

Question 2

Explanation

When no startup configuration file is found in NVRAM, the System Configuration Dialog will appear to ask if we want to enter the initial configuration dialog or not.

Question 3

Explanation

The “show process” (in fact, the full command is “show processes”) command gives us lots of information about each process but in fact it is not easy to read. Below shows the output of this command (some next pages are omitted)

show_process.jpg

A more friendly way to check the CPU utilization is the command “show processes cpu history”, in which the total CPU usage on the router over a period of time: one minute, one hour, and 72 hours are clearly shown:

show processes cpu history.jpg

+ The Y-axis of the graph is the CPU utilization.
+ The X-axis of the graph is the increment within the period displayed in the graph

For example, from the last graph (last 72 hours) we learn that the highest CPU utilization within 72 hours is 37% about six hours ago.

Question 4

Explanation

The “Age” field in the “show ip arp” command is the age in minutes of the cache entry. A hyphen (-) means the address is local so in this case 192.168.20.1, 192.168.40.1 & 192.168.60.1 are local to this router.

From the “Data Frame”, we learn that a packet is sent to Router1 and Router1 needs to forward it to the Destination IP 192.168.40.5. Therefore this router will:

+ Strip off the source MAC address and replace it with the MAC address 0000.0c36.6965 (because the IP address of this interface – 192.168.40.1 is in the same subnet with the Destination IP 192.138.40.5).
+ Strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320, which is the MAC of Destination host.
+ Forward the data packet out interface FastEthemet0/2 because this interface has the IP address of 192.168.40.1.

    There’s a typo in the Q4 explanation :

    Router1 needs to forward it to the Destination IP “192.138.40.5” (should be 192.168.40.5)

    Thanks

    Just memorizing the questions here is not really a good way to try to pass the CCNA exam. Cisco can make minor changes to some of the questions(and they do) and that can throw you off and make you fail. Also if you do pass and you don’t really know the material the hiring manager will know in the interview. I had multiple offers from different companies because I also used my own home CCNA Lab. I used the suggestions here http://www.certificationkits.com/cisco-lab-suggestions/ and their lab workbook was pretty awesome. It gave me the hands on knowledge going through about 70 labs step by step and actually being able to open up and play with the equipment. Each hiring manager was very impressed with my hands on knowledge even through I never worked on routers in a real business environment. So build your own lab! :)

    @Alvin- this might come as a complete shock to you, but not everyone has the money currently available to build their own home lab

    For data collection only: Q4 appeared on my exam questions today. All but one question on exam WAS listed here on 9tut. Got 1000 so answers are good. (labs: ACL and EIGRP – 2 friends before me stated NAT as well.)

    Would also like to note a question I did not see on 9tut. Fairly basic, but worth note. Not verbatim or course, but: How is a private address handled if it is placed on an ISP WAN interface. A: (although strictly not true) Private addresses can not be routed on the public internet backbone (or something to that effect).

    As an aside, I had a good handle on this material coming in. If you don’t know the material already, memorizing the test questions only hurts everyone.

    Q1 and Q4 was in exam. Praise The Lord and thnx 9tut passed on 24th june 986/1000.
    Some new questions to be observed:
    What will happen if a private IP address is assigned to a public interface connected to an ISP?
    A. Addresses in a private range will be not be routed on the Internet backbone.
    B. Only the ISP router will have the capability to access the public network.
    C. The NAT process will be used to translate this address to a valid IP address.
    D. A conflict of IP addresses happens, because other public routers can use the same range.
    Answer: A
    What are three values that must be the same within a sequence of packets for Netflow to consider
    them a network flow? (Choose three.)
    A. source IP address
    B. source MAC address
    C. egress interface
    D. ingress interface
    E. destination IP address
    F. IP next-hop
    Answer: A,D,E

    Q4..
    why answer B is not correct? can some one explain..??

  42. Anonymous
    May 5th, 2016

    Q4… why A is correct ? Router will just replace the source MAC address with some random MAC address in the same subnet ? IF someone can explain…

    Katomoto: Source and Dest IP addresses are not changing during the transmission of the frame, so B is not correct.

    i didn’t understand the line “+ Strip off the source MAC address and replace it with the MAC address 0000.0c36.6965 (because the IP address of this interface – 192.168.40.1 is in the same subnet with the Destination IP 192.138.40.5)” on question 4.

    Nowhere i have read router stripping the source mac address based on same subnet….
    Please explain…
