Q:

You are the network administrator and are given the tasks to plan for the future expansion of the network. You decide to subnet the current network of 172.15.0.0. What will be the subnet mask be if every subnet has to allocate 500 hosts.

A) 255.255.0.0 B) 255.0.0.0
C) 255.255.240.0 D) 255.255.254.0
 
Answer & Explanation Answer: D) 255.255.254.0

Explanation:

Explanation: The requirement of having to allocate 500 hosts on each subnet can be achieved by the following: 2^9 = 512. So deducting the broadcast and network address we have 510 possible hosts on each subnet. We used 9 bits to allocate the hosts, this leaves us 7 bits for possible subnets. Those 7 bits in binary is 1111 1110 or 254 in decimal.

Q:

We want to assign port 3 of our Catalyst 2950 switch to VLAN 3. What command will achieve this?

A) switch(config-if)#switchport vlan 3 B) switch#switchport access vlan 3
C) switch(config)#switchport access vlan 3 D) switch(config-if)#switchport access vlan 3
 
Answer & Explanation Answer: D) switch(config-if)#switchport access vlan 3

Explanation:

Explanation: The switchport access vlan [number] command will configure a switch port to that VLAN. You can also use the switchport access vlan dynamic command to configure the switch port automatically in a certain VLAN depending on the VLAN membership of the incoming packets. For both commands to work properly the switch port needs to be in access mode

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.
