1.Which of the following are the address ranges of the private IP addresses? (Choose three.) 10.0.0.0 to 10.255.255.255 
200.100.50.0 to 200.100.25.255
150.150.0.0 to 150.150.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255 
127.16.0.0 to 127.31.255.255
2.Which two functions of the OSI model occur at layer two? (Choose two.) physical addressing 
encoding
routing
cabling
media access control
3.

Refer to the exhibit. What function does router RT_A need to provide to allow Internet access for hosts in this network? address translation
DHCP services
ftpd
web server
4.What is true regarding network layer addressing? (Choose three.) uses a flat structure
prevent broadcasts
heirarchical
uniquely identifies each host
48 bits in length
contains a network portion

5.

Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A

leaving ATL
leaving Dallas 
leaving NYC

6.

Refer to the exhibit. Assume all devices are using default configurations. How many subnets are required to address the topology that is shown? 1
3
4
5
7
7.A technician is asked to secure the privileged EXEC mode of a switch by requiring a password. Which type of password would require this login and be considered the most secure? console
enable
enable secret 
VTY

8.

Refer to the exhibit. A technician is working on a network problem that requires verification of the router LAN interface. What address should be pinged from this host to confirm that the router interface is operational? 127.0.0.1

192.168.64.196
192.168.254.1 
192.168.254.9
192.168.254.254
9.Which OSI layer does IP rely on to determine whether packets have been lost and to request retransmission? application
presentation
session
transport
10.When connectionless protocols are implemented at the lower layers of the OSI model, what is usually used to acknowledge that the data was received and to request the retransmission of missing data? IP

UDP
Ethernet
a connectionless acknowledgement
an upper-layer, connection-oriented protocol or service

Refer to the exhibit. Host C is able to ping 127.0.0.1 successfully, but is unable to communicate with hosts A and B in the organization. What is the likely cause of the problem? Hosts A and B are not on the same subnet as host C.

The IP addresses on the router serial interfaces are wrong.
The subnet mask on host C is improperly configured. 
The FastEthernet interface fa0/0 of router 1 is wrongly configured.

Refer to the exhibit. Which list refers only to end devices? D,E,F,G
A,H,B,C
A,D,E,F
A,D,E,G

Refer to the exhibit. Host A sends a frame with the destination MAC address as FFFF.FFFF.FFFF. What action will the switch take for this frame? It will drop the frame.
It will send the frame back to host A.
It will send the frame to all hosts except host A. 
It will forward the frame to the default gateway.
Which subnet mask will allow 2040 hosts per subnet on the IP network 10.0.0.0? 255.255.0.0
255.255.254.0
255.255.252.0
255.255.248.0 
255.255.240.0
255.255.255.128

Refer to the exhibit. RouterB is configured properly. The Ethernet interface Fa0/0 of RouterA is configured with the use of the commands that are shown. However, a ping from the Fa0/0 interface of RouterA to the Fa0/0 interface of RouterB is unsuccessful. What action should be taken on RouterA to solve this problem? Use the description command on the FastEthernet interface Fa0/0. Configure the clock rate of the FastEthernet interface Fa0/0. Use the no shutdown command on the FastEthernet interface Fa0/0.  Reboot the router.
