Exam 9: Lan Architecture and Protocols

One of the advantages of having a bottom up approach to building a LAN is that individual managers are very close to the group and therefore understand the needs of the department and can respond quickly .

Coaxial cable is less susceptible to electromagnetic interference,but more expensive,when compared with twisted pair cables.

Problems with using a single Local Area Network (LAN)to interconnect devices on a premise include

The fact that signal strength falls off with distance is called

Back-end Networks are used in situations where a few large computers must be connected for low-volume data transfers.

Which of the following is NOT one of the distinguishing characteristics for optical fiber cables compared with twisted pair or coaxial cables?

The capacity of optical fiber cable is more than 1000 times greater than coaxial cables.

Which of the following is NOT one of the characteristics of a building wiring scheme using a structured cabling system?

When examining a MAC frame of data starting with the first bit,which of the following describes the order of the various headers found in the frame?

Twisted pair wires are immune from all interference due to electromagnetic coupling because of the twisting of the wires.

One rationale for not employing Local Area Network (LAN)technology for an entire premise is because there are differing levels of equipment,such as PCs,servers,and mainframes.

A Storage Area Network (SAN)is a network specifically designed to allow specific servers the ability to share local storage devices with each other.

Which of the following is NOT on of the typical characteristics of back-end networks?

Which of following is NOT one of the design that determines data rate and distance?

Even for large companies,isolated personal computers are often more than sufficient for current computer based tasks.

The major difference between Category 3 UTP and Category 5 UTP is that the latter uses a larger sized wire for the conductors.

One of the challenges when adopting a top down design approach to networks is that the company must understand the individual needs of each department and be responsive.
