Networking Week 3

An IPv4 address can be broken down into two parts. These are:

• Network portion and transport portion

• Network portion and host portion

• Gateway portion and host portion

• Source portion and destination portion

How many bits make up an IPv4 address?

• 
  8

• 16

• 32

• 64

CHOOSE 3

• A,B,G

• A,E,G

• B,F,D

• I,H,F

Refer to the diagram. A packet header has destination IP address 192.168.5.4 and source IP address 192.168.7.60. Which workstation should receive the packet?

• A

• B

• C

• D

• E

Refer to the diagram. A packet header has destination IP address 192.168.5.4 and source IP address 192.168.7.60. Which workstation originated the packet?

• A

• B

• C

• D

• F

Refer to the diagram. Host A is sending a packet addressed to host F. What will the router do?

• 
  It will use the destination IP address to work out the network address
  192.168.7.0 and forward the packet to this network.

• 
  It will use the destination IP address to work out the network address
  192.168.5.0 and forward the packet to this network.

• It will use the source IP address to work out the network address 192.168.7.0
  and forward the packet to this network.

• 
  It will use the source IP address to work out the network address 192.168.5.0
  and forward the packet to this network.

Refer to the diagram . If the default gateway configured on host A is wrong, what is the likely effect?

• 
  Host A will not be able to communicate with any other host.

• Host A will be able to communicate with its local switch and router but not
  with any other workstation.

• Host A will be able to communicate with workstations B and C, but not D, E
  or F.

• 
  Host A will be able to communicate with workstations D, E and F but not B or
  C.

Refer to the diagram. The router receives a packet addressed to 192.168.6.24. What will the router do? (Choose 2 options.)

• 
  The router will drop the packet.

• 
  The router will send the packet on the default route if one exists.

• The router will forward the packet to all connected networks.

• The router will forward the packet to the 192.168.7.0 network.

• 
  The router will forward the packet to the 192.168.5.0 network.

Refer to the diagram. What is the address of the network that host D is on?

• 
  192.168.7.26

• 
  192.168.7.20

• 192.168.7.253

• 192.168.7.254

• 192.168.7.0

Refer to the diagram. What should be configured as the default gateway for host A?

• 192.168.5.3

• 
  192.168.5.253

• 192.168.5.254

• 192.168.7.254

• .

  192.168.7.253
