New CCNA – Operation 2

September 27th, 2013 Go to comments

Question 1

Refer to the exhibit. A network technician is asked to design a small network with redundancy. The exhibit represents this design, with all hosts configured in the same VLAN. What conclusions can be made about this design?

IP_Address_wrong_assignment.jpg

A. The design will function as intended
B. Spanning-tree will need to be used.
C. The router will not accept the addressing scheme.
D. The connection between switches should be a trunk.
E. The router interfaces must be encapsulated with the 802.1Q protocol.

 

Answer: C

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

Refer to the exhibit. What can be determined about the router from the console output?

1 FastEthernet/IEEE 802.3 interface(s)
125K bytes of non-volatile configuration memory.
65536K bytes of ATA PCMCIA card at slot 0 (Sector size 512 bytes) .
8192K bytes of Flash internal SIMM (Sector size 256K).

———-System Configuration Dialog ———-

Would you like to enter the initial configuration dialog? [yes/no]:

A. No configuration file was found in NVRAM.
B. No configuration file was found in flash.
C. No configuration file was found in the PCMCIA card.
D. Configuration file is normal and will load in 15 seconds.

 

Answer: A

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

Which command displays CPU utilization?

A. show protocols
B. show process
C. show system
D. show version

 

Answer: B

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

Refer to the exhibit:

show_ip_arp.jpg

What will Router1 do when it receives the data frame shown? (Choose three)

A. Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.
B. Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1.
C. Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.
D. Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1.
E. Router1 will forward the data packet out interface FastEthernet0/1.
F. Router1 will forward the data packet out interface FastEthernet0/2.

 

Answer: A C F

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)

    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
