* If a packet is sent to a network device other than and, an ARP request must be used.
* If the computer with the IP address of sends a packet to the device with the IP address, no ARP request is required.

internet layer
transport layer
application layer

11 Which subnet mask would be assigned to the network address of to provide 254 useable host addresses per subnetwork?

12 Refer to the exhibit. Host A pings host B. When R4 accepts the ping into the Ethernet interface, what two pieces of header information are included? (Choose two.)
source IP address:
source IP address: BBBB.3333.5677
source MAC address: 5555.AAAA.6666
destination IP address:
* destination IP address:
* destination MAC address: 9999.DADC.1234

13 What header address information does a router change in the information it receives from an attached Ethernet interface before information is transmitted out another interface?
only the Layer 2 source address
only the Layer 2 destination address
only the Layer 3 source address
only the Layer 3 destination address
* the Layer 2 source and destination address
the Layer 3 source and destination address

14 Host A is connected to the LAN, but it cannot connect to the Internet. The host configuration is shown in the exhibit. What are the two problems with this configuration? (Choose two.)
* The host subnet mask is incorrect.
The host is not configured for subnetting.
The default gateway is a network address.
* The default gateway is on a different network than the host.
The host IP address is on a different network from the Serial interface of the router.

15 An IP network address has been subnetted so that every subnetwork has 14 usable host IP addresses. What is the appropriate subnet mask for the newly created subnetworks?

16 A company is using a Class B IP addressing scheme and expects to need as many as 100 networks. What is the correct subnet mask to use with the network configuration?

17 Refer to the exhibit. The network administrator has assigned the internetwork of LBMISS an address range of This address range has been subnetted using a /29 mask. In order to accommodate a new building, the technician has decided to use the fifth subnet for configuring the new network. By company policies, the router interface is always assigned the first usable host address and the workgroup server is given the last usable host address. Which configuration should be entered into the IP server properties to get connectivity to the network through the router?
IP address: Subnet mask: Default gateway:
IP address: Subnet mask: Default gateway:
* IP address: Subnet mask: Default gateway:
IP address: Subnet mask: Default gateway:
IP address: Subnet mask: Default gateway:

18 Refer to the exhibit. A technician is planning an addressing scheme for a branch office as shown in the exhibit. What is the status of the intended network?
The configuration will work as planned.
The subnetwork mask of host A is incorrect.
The default gateway of host A is a network address.
* The addresses on the router LAN interfaces are on the same subnetwork.
The IP address of host A is on a different subnetwork than the subnetwork that the Ethernet router interface is on.

19 Refer to the exhibit. After host 2 is connected to the switch on the LAN, host 2 is unable to communicate with host 1. What is the cause of this problem?
The subnet mask of host 2 is incorrect.
* Host 1 and host 2 are on different networks.
The switch needs an IP address that is not configured.
The router LAN interface and host 1 are on different networks.
The IP address of host 1 is on a different network than is the LAN interface of the router.

20 Refer to the exhibit. A network administrator is planning the addressing scheme for the LAN using The hosts are to be assigned addresses – The LAN interface of the router is to be configured using as the IP address. What would describe this addressing scheme?
The LAN is being addressed properly.
The subnet that is being assigned is not a usable subnet address.
* The router LAN interface is being assigned a broadcast address.
The subnet mask does not allow enough host addresses in a single subnet.

21 Which type of routing allows routers to adapt to network changes?
static routes
* dynamic routing
only default routes
No routing is necessary.

22 How does a router decide where the contents of a received frame should be forwarded?
* by matching destination IP addresses with networks in the routing table
by matching the destination IP address with IP addresses listed in the ARP table
by matching the destination MAC address with MAC addresses listed in the CAM table
by forwarding the frame to all interfaces except the interface on which the frame was received

23 What do switches and routers use to make forwarding decisions?
Switches and routers both use IP addresses.
Switches and routers use both MAC and IP addresses.
Switches use IP addresses. Routers use MAC addresses.
* Switches use MAC addresses. Routers use IP addresses.
Switches use MAC and IP addresses. Routers use IP addresses.

24 Refer to the exhibit. A newly hired technician is testing the connectivity of all hosts by issuing a ping command. The technician notices that a default gateway is not configured on all the hosts, but all hosts have connectivity between hosts, a fact which seems to confuse the technician. How would you explain the connectivity to the technician?
The hosts are detecting the default gateway configured on the hub.
* The hosts are all in one LAN, so default gateway information is not needed.
The hosts in the network only require that one host has a gateway configured.
The hosts in the network would only need a gateway if a switch replaces the hub.
The hosts are using broadcast to reach each other since no gateway is configured.

25 Given a host with the IP address and a default subnet mask, to which network does the host belong?
