Question 4:
Which of the following is true about a CSMA/CD network?

B. One node's transmission goes to the nearest router that sends it directly to the destination.
C. Signals are sent directly to the destination if both the MAC and IP addresses are known by the source.
D. One node's transmission traverses the entire network and is seen and checked by every node.

Question 5:
Which best describes the function of the Physical Layer?
A. Provides network services to user applications.
B. Establishes, maintains, and manages sessions between applications.

Why has a layered network model been developed?
A. Stabilizes development times and reduces number of proprietary hardware schemes.
B. Takes a holistic approach to networking and encourages comprehensive engineering solutions.

D. It is located on the DHCP server

Question 13:
What best describes the functions of the Application Layer?
A. Establishes, manages, and terminates applications?
B. Supports communicating components of applications such as e-mail
C. Defines end-to-end delivery of packets
D. Translates between different data formats such as ASCII and EBCDIC

Question 14:
Host A and host Z are on different subnets. If an ARP request is sent from host A in search of host Z's MAC address, what will happen?
A. There will be no response.
B. The router will respond with the MAC address of host Z.
C. The router will respond with it's own MAC address.
D. The router will forward the request to the correct subnet so host Z can respond.

Question 15:
What happens if host A broadcasts an ARP request looking for the MAC address of host B which is located on the same network as host A?
A. The name server looks at the request and replies with the MAC address of host B.
B. All devices look at the request and any device will reply with the IP address of host B.
C. All devices look at the request and ONLY host B will reply with the MAC address.
D. The nearest router looks at the request and replies with the MAC address of host B or forwards the request to another router.

Question 16:
Which network device offers full-duplex, dedicated bandwidth to segments or desktops?
A. Hub
B. Bridge
C. Ethernet switch
D. Router

Question 17:

A. 2
B. 6
C. 14
D. 30

Question 18:
Which OSI Layer determines best path selection?
A. Transport Layer
B. Network Layer
C. Data Link Layer
D. Physical Layer

What is the data-link destination address of a broadcast message?
A. 111.111.111.111
B. 255.255.255.255
C. AAAA.AAAA.AAAA

Question 21:
What happens after a collision has occurred on a network after the jam signal is sent?
A. The router clears the route and notifies the source to resend
B. All stations stop sending frames for a randomly selected time period
C. A keepalive signal is generated to hold the message until the route clears
D. The source station waits for the collision to dissipate and then broadcasts an all clear

lol.. now you get to learn router commands. that's FUN FUN stuff..

just remember banner motd .. that's all that's important
