Which two functions of the OSI model occur at layer two? (Choose two.)
physical addressing
encoding
routing
cabling
media access control

Refer to the exhibit. What function does router RT_A need to provide to allow Internet access for hosts in this network?

1. Which options are properties of contention-based media access for a shared media? (Choose three.)
non-deterministic
less overhead
one station transmits at a time
collisions exist
devices must wait their turn
token passing
2. What is a primary purpose of encapsulating packets into frames?
provide routes across the internetwork
format the data for presentation to the user
facilitate the entry and exit of data on media
identify the services to which transported data is associated

1.

Refer to the exhibit. What command will place the router into the correct mode to configure an appropriate interface to connect to a LAN?

UBAMA# configure terminal
UBAMA(config)# line vty 0 4
UBAMA(config)# line console 0
UBAMA(config)# interface Serial 0/0/0
UBAMA(config)# interface FastEthernet 0/1


2. In a Cisco router, when do changes made to the running-configuration take effect?

after a system restart
**as the commands are entered
when logging off the system
when the configuration is saved to the startup-configuration

1.

Refer to the exhibit. A student working in the lab selects a cable that is wired as shown. Which connection types can successfully be made with this cable? (Choose two.)

connecting a PC to a router’s console port
connecting two routers together via their fast ethernet ports
connecting two switches together at gigabit speeds
connecting a PC to a switch at Gigabit Ethernet speeds
connecting two devices with the same interface type at Fast Ethernet speeds


2. Which three statements are true about the role of routers in the network? (Choose three.)
They propagate broadcasts.
They enlarge collision domains.
They segment broadcast domains.
They interconnect different network technologies.
Each router interface requires a separate network or subnet.
They maintain a common frame format between LAN and WAN interfaces.

3.

Refer to the exhibit. A network administrator has decided to use packet capture software to evaluate all traffic from the student subnet on the way to the Internet. To ensure that all packets are captured, what network device should be used to connect the monitoring station to the network between R1 and R2?

1. Ethernet operates at which layers of the OSI model? (Choose two.)

• Network layer
• Transport layer
• Physical layer
• Application layer
• Session layer
• Data-link layer

2. In the graphic, Host A has reached 50% completion in sending a 1 KB Ethernet frame to Host D when Host B wishes to transmit its own frame to Host C. What must Host B do?

• Host B can transmit immediately since it is connected on its own cable segment.
• Host B must wait to receive a CSMA transmission from the hub, to signal its turn.
• Host B must send a request signal to Host A by transmitting an interframe gap.
• Host B must wait until it is certain that Host A has completed sending its frame.

3. Which of the following describe interframe spacing? (Choose two.)

An installed fiber run can be checked for faults, integrity, and the performance of the media by using what device?

When is a rollover cable used in a network?
	for connecting a host to a Fast Ethernet port on a switch
	for connecting a router to another router
	for connecting two routers through their AUX ports
	for connecting to a switch through its console port
