If a user on the PC pings the website, www.tcpipguru.com, what would be the destination IP address of the IP packet carrying the icmp (ping) data send from the PC.
- A.
192.168.1.1
- B.
Www.tcpipguru.com

- 7.A PC is configured with an IP address 192.168.1.2 and subnet mask 255.255.255.0. The default gateway on the TCP/IP adapter settings of the PC is not configured. The default gateway, which is the router, is configured with an IP address of 192.168.1.1 and subnet mask 255.255.255.0. What would happen if a user on the PC issues the command ping 192.168.1.1.
- A.
A response would be received from the router on the PC.
- B.
The packet would be dropped on the PC
- C.
The packet would be dropped on the router
- D.
The router would receive the packet , but a response would not be received by the PC.
- 8.
Refer the exhibit - E0 and E1 interface of the router is configured with IP address 192.168.1.1/24 and 192.168.2.1/24. The IP address of PC1 is 192.168.1.2/24 and the default gateway is 192.168.1.1. The IP address of PC2 is 192.168.2.2/24. If a user on PC1 issues the command ping 192.168.2.2, what would be the source IP address of the IP packet carrying the icmp (ping) packet when it exits the E1 interface of the router.- A.
192.168.1.2
- B.
192.168.2.1
- C.
192.168.1.1
- D.
192.168.2.2
- 9.The IP address of a PC is 192.168.1.2/24 and the default gateway is 192.168.1.1. Which of the following actions would result in the request to be send to the default gateway.
- A.
Ping www.tcpipguru.com
- B.
Http://www.tcpipguru.com (On the browser)
- C.
Ping 192.168.2.3
- D.
All of the above
- 10.How do routers derive network address for directly connected interfaces.
- A.
The network address has to be manually configured.
- B.
The network address is derived from the IP address and subnet mask configured on the interface
- C.
The network address is derived from the IP address configured on the interface.
- D.
A network address is not required for directly connected interfaces.
- 11.Two routers are directly connected. What should be used so that the routing table on the routers are exchanged with each other.
- A.
This is not possible
- B.
Dynamic routing protocols should be configured on both the routers
- C.
The routing table information should be manually configured on both the routers
- D.
Routing tables would be exchanged since the routers are directly connected.
- 12.A PC is connected to a switch, which is connected to a router. The router is connected to the internet and has the default gateway configured on it. The PC does not have a default gateway configured on it's TCP/IP adapter settings. Will the PC be able to access the internet.
- A.
Yes
- B.
No
- 13.A router has three interfaces, E0, E1 and E2. If the router receives an ethernet frame with destination mac-address FF-FF-FF-FF-FF-FF on E0 , which among the following is true
- A.
The router would forward the frame to E1 and E2 interface
- B.
The router will not forward the frame to E1 and E2 interface
- C.
The router would forward the frame on E0, E1 and E2 interface
- D.
None of the above
- 14.What would a router do if it receives an IP packet with TTL value as 1
- A.
The router would forward the packet to the appropriate destination.
- B.
The router would decrement the TTL value and then forward the packet.
- C.
The router would drop the packet.
- D.
The next hop for the router would drop the packet.
- 15.A router has two directly connected networks - 192.168.1.0/24 and 192/168.2.0/24. What should be configured on the router for enabling communication between the networks.
- A.
