Q:

What is the difference between the types of routes allowed by default into IS-IS and OSPF areas?

Answer

By default, all routes are advertised into all OSPF areas. This includes interarea OSPF routes and external routes that have been injected into OSPF. By default, IS-IS does not advertise interarea or external routes into an area, but injects a default route.

Q:

Explain the difference between a classful and a classless routing protocol.

Answer

Classless routing protocols advertise subnet mask information along with the network prefixes. Classful routing protocols do not. Therefore, for a classful protocol, all subnets for the major network number being used must be the same length. Also, classful protocol cannot support discontiguous networks prefixes.

Q:

Describe the difference between routing and switching.

Answer

Routing moves a letter or telephone call to the access layer (as in a street or telephone exchange). Switching makes the final delivery. A switching decision is made on the part of the address that is not used in routing (as in the street number or last four digits of a phone number).

Q:

Which three IP addresses can be assigned to hosts if the subnet mask is /27 and subnet zero is usable?

A. 10.15.32.17
B. 17.15.66.128
C. 66.55.128.1
D. 135.1.64.34
E. 129.33.192.192
F. 192.168.5.63

Answer

Answer : A C D


 


 


 


Explanation: If you follow the cram table,  /27 is mask 255.255.255.224. 3 bits were borrowed with value of 32. Follow the fourth octets of the addresses:
A is a usable host address.
B is classified as a network address
C is a usable host address form the subnet 0
D is a usable host address
E is a network address
F is a broadcast address

Q:

If one of the host connected to Sw-AC3 wants to send message to ip 190.0.2.5 (or any ip on a different subnet) what will be the destination MAC address ?

Answer

Answer and Explanation:


Because the destination address is on a different subnet from the switch, the packet will be forwarded to its default gateway. To verify the default gateway of this switch, use the show running-config command



From the output above, we can see that its default-gateway is 192.168.1.254. Which can be said to be a layer 3 device (router); in this case, the VLAN-R1 router. You can use the show cdp neighbor detail command verify further.



From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 192.168.1.254).The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3. To verify the MAC address associated this interface is interface, you use the show mac-address-table command:



Looking closely at the table above, you will discorver that the corresponding MAC address is 000a.b7e9.8360. Although there are some entries on port Fa0/3 with different Vlans ,but they have the same MAC address.


From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 192.168.1.254).The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3. To verify the MAC address associated this interface is interface, you use the show mac-address-table command

Q:

Solve the below puzzle

Complete the five words below in such a way that the two letters that end the first word also start the second word, and the two letters that end the second word also start the third word etc. The same two letters that end the fifth word also start the first word, to complete the cycle

** IV **
** OT **
** IC **
** NG **
** RA **

Answer

Given that the next word should start with the ending two letters of the previous word. From this,


 


The first word is


SHIVER


Now, the next word should start with ER and must contain OT in the middle.


EROTIC


Now, the next word should start with IC and must contain IC in the middle.


ICICLE


Now, the next word should start with LE and must contain NG in the middle.


LENGTH


Now, the next word should start with TH and must contain RA in the middle.


THRASH


 


 


Hence, the required five words are SHIVER, EROTIC, ICICLE, LENGTH, THRASH.
