ICND1 – Router Questions

Question 1

Explanation

When packets travel through many routers, the source and destination IP addresses do not change but the source and destination MAC do change.

Question 2

Explanation

The output above is unclear. Normally when we use this command we can see the type of serial connection on this interface, for example “V.35 DCE cable. Below is an example of the same command as above:

RouterA#show controllers serial 0
HD unit 0, idb = 0xECA4C, driver structure at 0xF1EC8
buffer size 1524 HD unit 0, V.35 DTE cable
cpb = 0x62, eda = 0x403C, cda = 0x4050
RX ring with 16 entries at 0x624000
00 bd_ptr=0x4000 pak=0x0F5704 ds=0x62FFB8 status=80 pak_size=22

Or

RouterB#show controllers serial 0
buffer size 1524 HD unit 0, V.35 DCE cable, clockrate 64000
cpb = 0x62, eda = 0x408C, cda = 0x40A0
RX ring with 16 entries at 0x624000
00 bd_ptr=0x4000 pak=0x0F2F04 ds=0x627908 status=80 pak_size=22

but in this case we only get “V.35 cable”. So in fact we are not sure about the answer C. But the output above also does not have any information to confirm other answers are correct or not.

Just for your information, the V.35 male and V.35 female cable are shown below:

Question 3

Question 4

Question 5

Explanation

The outputs of “show protocols” and “show ip interface” are shown below:

Global values:

Internet address is 10.1.1.1/30
Serial0/1 is up, line protocol is down
Internet address is 209.65.200.225/30
Serial0/2 is up, line protocol is down
Serial0/3 is up, line protocol is down
NVI0 is up, line protocol is up
Interface is unnumbered. Using address of NVI0 (0.0.0.0)
Loopback0 is up, line protocol is up
Internet address is 10.1.10.1/32
Loopback1 is up, line protocol is up
Internet address is 10.1.2.1/27
Loopback6 is up, line protocol is up
Serial0/0 is up, line protocol is down
Internet address is 10.1.1.1/30
Broadcast address is 255.255.255.255
Address determined by non-volatile memory
MTU is 1500 bytes
Helper address is not set

IP Feature Fast switching turbo vector
IP multicast fast switching is enabled
IP multicast distributed fast switching is disabled
IP route-cache flags are Fast
Router Discovery is disabled
IP output packet accounting is disabled
IP access violation accounting is disabled
TCP/IP header compression is disabled
RTP/IP header compression is disabled
Policy routing is disabled
Network address translation is enabled, interface in domain inside
BGP Policy Mapping is disabled
WCCP Redirect outbound is disabled
WCCP Redirect inbound is disabled
WCCP Redirect exclude is disabled

Question 6

Explanation

The “Ctrl-Shift-6” and “x” is used to suspend the telnet session. In this case, the telnet session from Router1 to Router2 will be suspended.

If we enter the keyword “resume”, Router1 will try to resume the telnet session to Router2 (you will see the line [Resuming connection 1 to 192.168.9.2 … ]) and we will get back the Router2> prompt.

Question 7

Explanation

The Layer 2 information (source and destination MAC) would be changed when passing through each router. The Layer 3 information (source and destination IP addresses) remains unchanged.

Question 8

Explanation

When packets travel through many routers, the source and destination IP addresses do not change but the source and destination MAC do change.

Question 9

Explanation

Change the configuration register to 0x2142. With this setting when that router reboots, it bypasses the startup-config and no password is required.

    What really is the answer for Q5??

    I also think that “show IP interface” is the answer. I’m not sure why; But I tried C&D on Q5 on the exam and got 100% in all categories except “Network device security”. And I’m Pretty sure that this question doesn’t fall on that category. So for everyone arguing with the answer, just check it out yourself. Cheers!

    Passed with the 285q dumps from IT-Libraries. Only a few new questions around 3, it’s passable with dumps only

    Good luck!

    PS: there is a link to the dumps here http://www.9tut.net/icnd1-100-105/new-icnd1-basic-questions-2 Comment by Irina
