Answers to Questions 36-40

36. A brouter operates on the _______ layer of the OSI model.

A. Data Link

B. Physical

C. Presentation

D. Transport

E. Session

Explanation: A brouter is a hybrid device that is part router and part bridge. They are considered legacy devices.

A brouter operates on the DataLink layer of the OSI model.

& Domain 2.4: Identify the OSI layers to which the following network components operate: Hubs, Switches, Bridges, Routers, Network Interface Cards.


 

37. What multi-port device connects network segments and allows full bandwidth on all ports?

A. Repeater

B. Hub

C. Switch

D. MAU

E. Router

Explanation: The key words here are "full bandwidth". That means data can be sent in both directions between nodes, and drastically improved data transfer rates on a LAN can be achieved. In contrast to a hub, a switch sends data only to the intended recipient(s) whereas a hub broadcasts it to all nodes.

& Domain 2.4: Identify the OSI layers to which the following network components operate: Hubs, Switches, Bridges, Routers, Network Interface Cards.


 

38. Which of the following devices translates dissimilar network protocols?

A. Router

B. Repeater

C. Switch

D. Gateway

E. Hub

Explanation: A gateway is a device that operates on the Data link layer of the OSI model and translates protocols for transmission over networks.

& Domain 2.2: Identify the 7 layers of the OSI model and their functions.


 

39. IP numbers are assigned to _______ devices.

A. Cables Numbers

B. Hub

C. Host

D. Patch Panel

E. UPS

Explanation: A NIC is actually a "host device". We use this generic term because IP addresses can be assigned to more than just NICs. Printers and copiers, for instance, can have their own IP addresses. In the context of computer networking, the NIC is what allows your PC to interface with the rest of the network, thus it is a "Network Interface Card".

& Domain 2.2: Identify the 7 layers of the OSI model and their functions.


 

40. You use NetBEUI exclusively on your network. Traffic is heavy. What can be done to increase performance?

A. Segment the network with a bridge

B. Use a gateway

C. Use a repeater

D. Use a router

E. Use a proxy server to isolate IP addresses

Explanation: Segmenting the network with a bridge would divide traffic between the two segments, sharply reducing congestion. NetBEUI is non-routable (can not go outside a LAN), so a router would have no effect on reducing traffic. A proxy server is for filtering and caching web content, and serves as a firewall.

& Domain 2.3: Differentiate between following protocols in terms of routing, address schemes, interoperability, and naming conventions: TCP/IP, IPX/SPX, NetBEUI, AppleTalk
