9. The OSI layer is responsible for using electric (or sometimes other types of) signaling to get bits from one computer to another. This layer’s components don’t care what the bits mean; their job is to get the bits from point A to point B, using whatever kind of optical, electrical, or wire- less connection that connects the points. What layer in the OSI model are we referring to?

A. Application layer
B. Data-Link layer
C. Network layer
D. Transport layer
E. Physical layer

Answer: E. The Physical layer is concerned with signaling, specifically through ccna exam
electrical, optical, or radio signals. This layer’s components don’t care what the bits mean; their job is to get the bits from point A to point B via the optical, electrical, or wireless connection between the points.

10. You have been hired by a small travel agency to set up a Microsoft Windows network. Currently the travel agency has six travel agents who use Windows XP Professional and Vista. The computers are stand-alone machines with no network connection. ...
... The owner of the travel agency wants all the agents to be able to share resources (files and printers), but they are very concerned with minimizing costs. What type of network should you install?

A. Stand-alone network
B. Active Directory domain-based network
C. Peer-to-peer network
D. Client/server-based network

Answer: C. A peer-to-peer network works well with a company mcse 2008
that has 12 or fewer users. The advantage of a peer-to-peer network is that users can share resources across a network without spending money on powerful equipment and server software.

11. This OSI layer provides for the flow of data over a single physical link from one device to another. It accepts packets from the Network layer and packages the information into data units called frames; these frames are presented to the Physical layer for transmission. This OSI layer adds control information, such as the frame type, to the data being sent. This layer also provides for the error-free transfer of frames from one computer to another. Which OSI layer does these tasks?

A. Application layer
B. Data-Link layer
C. Network layer
D. Transport layer
E. Physical layer

Answer: B. The Data-Link layer provides for the flow of data over a single physical link from one device to another. It accepts packets from the Network layer and packages the information into data units called frames ; these frames are presented to the Physical layer for transmission. The Data- Link layer adds control information, such as frame type, to the data being sent.
