Q

In which type of network is there no dedicated server, with each node on the network being an equal resource for sharing and receiving information?

Client-server

Peer-to-peer

Windows Server 2016

A

Peer-to-peer

A peer-to-peer network has no dedicated servers. There are no hierarchical differences between the workstations in the network; each workstation can decide which resources are shared on the network. In a peer-to-peer network, all workstations are clients and servers at the same time

Q

What is the Microsoft term for a peer-to-peer network?

Client-server

Domain

Workgroup

A

Workgroup

The Microsoft term for a peer-to-peer network is a workgroup environment. If you have not installed your Windows clients in a domain (client-server), then they are in a workgroup environment

Q

The physical layout of computers, cables, and other components on a network is known as what?

Segment

Backbone

Topology

A

Topology

The topology is the physical layout of computers, cables, and other components on a network. Many networks are a combination of the various topologies

Q

Which topology has a centralized location in which all of the cables come together to a central point such that a failure at this point brings down the entire network?

Bus

Star

Mesh

A

Star

In a star topology, all computers are connected through one central hub or switch. A star topology actually comes from the days of the mainframe system. The mainframe system had a centralized point at which the terminals connected

Q

Which topology has a layout in which every workstation or peripheral has a direct connection to every other workstation or peripheral on the network?

Bus

Star

Mesh

A

Mesh

A mesh topology is not very common in computer networking, but you have to know it for the exam. The mesh topology is seen more often with something like the nationwide telephone network. With a mesh topology, every workstation has a connection to every other component of the network

Q

You have four switches connected together with twisted-pair cabling. Systems connected to switch two cannot seem to communicate with the rest of the network. What could be the problem?

It is using an LC connector to connect to the other switches.

It is using an ST connector to connect to the other switches.

It is not using a crossover to connect to the other switches.

A

It is not using a crossover to connect to the other switches.

When connecting similar devices, you should use a crossover cable, which switches the placement of the transmit and receive wires on one end of the cable to allow similar devices such as two switches to communicate

Q

You want to create a crossover cable to connect two systems directly together. Which wires would you have to switch at one end of the cable?

Wires 1 and 2 with wires 3 and 6

Wires 2 and 3 with wires 6 and 8

Wires 1 and 2 with wires 3 and 4

A

Wires 1 and 2 with wires 3 and 6

To create a crossover cable, you would switch wires 1 and 2 with wires 3 and 6 on one end of the cable

Q

Which access method does 100BaseT use?

Baseband

CSMA/CD

CSMA/CA

A

CSMA/CD

Carrier sense multiple access with collision detection (CSMA/CD) is the access method that 100BaseT uses. With CSMA/CD, a host will sense the wire to see if it is free; only if the wire is free of data will the host send data

Q

Which network architecture uses single-mode fiber-optic cabling?

1000BaseLX

1000BaseSX

1000BaseCX

A

1000BaseLX

1000BaseLX uses single-mode fiber-optic cabling

18
Q

Which type of cabling is used in a 10BaseFL network?

Thinnet

Thicknet

Fiber-optic

A

Fiber-optic

10BaseFL uses fiber-optic cabling. Remember to watch the characters at the end of the architecture name to determine what the cable type is—”FL” is for fiber link

19
Q

Which Gigabit architecture uses multimode fiber cabling?

1000BaseLX

1000BaseSX

1000BaseCX

A

1000BaseSX

1000BaseSX uses multimode fiber cabling. Remember that multimode cannot go as far as single mode, and also the “SX” in the architecture is for “short range”—multimode for short range; single mode for long range
