Question 1

One of the drawbacks to Ethernet is that many of the versions use _____.
A) broadband
B) NICs
C) tokens
D) CSMA/CD

Accepted Answer

The CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol used in Ethernet can lead to collisions and slowdowns in network performance.

Question 2

Each is a dominant network standard except _____.
A) Ethernet
B) Titan
C) token ring
D) wireless

Accepted Answer

Titan is not a dominant network standard. Ethernet, token ring, and wireless are all recognized standards for networking, with Ethernet and wireless being particularly widespread in both personal and professional use. Token ring was more common in the past. Titan does not fit into the category of a networking standard.

Question 3

10Base-T is a star-wired bus topology.

Accepted Answer

10Base-T is a type of Ethernet networking technology that uses twisted-pair cables and a hub or switch to connect devices in a star topology.

Question 4

Segments on a 10Base2 network are connected together through a device known as a _____.
A) router
B) repeater
C) hub
D) switch

Accepted Answer

10Base2 networks, also known as Thinnet, primarily use repeaters to connect segments. Repeaters regenerate the signal to extend the network's reach.

Question 5

100Base-T has many of the same basic characteristics as 10Base-T.

Accepted Answer

100Base-T and 10Base-T both use twisted pair cables, have a maximum cable length of 100 meters, and use a similar signaling technique. However, 100Base-T is 10 times faster than 10Base-T, with a maximum data rate of 100 Mbps compared to 10 Mbps.

Question 6

A patch cable has a(n) _____ connector on each end.
A) RJ-11
B) CR-NIC
C) CAT5E
D) RJ-45

Accepted Answer

RJ-45 connectors are typically used for Ethernet networking and are the most common connector type found on patch cables. RJ-11 connectors are typically used for telephone lines and are not commonly used for patch cables. CR-NIC and CAT5E are not connector types, but rather terms used to describe different aspects of network connectivity (CR-NIC stands for Cardbus/RJ-45 Network Interface Card, and CAT5E refers to a specific category of Ethernet cable).

Question 7

The "10" in 10Base-T indicates the network's _____.
A) maximum speed of 10 Mbps
B) maximum number of devices
C) minimum number of segments
D) total number of NICs

Accepted Answer

The "10" in 10Base-T refers to the maximum speed of the network, which is 10 Mbps. The other options are not related to the naming convention of 10Base-T.

Question 8

A computer on a 10Base-T network must be within _____ meters of the hub.
A) 1
B) 10
C) 100
D) 10000

Accepted Answer

100 meters is the maximum length for a cable segment in a 10Base-T Ethernet network.

Question 9

IEEE Project 802.3 set specifications for a type of local area network known as _____.
A) 15Base-5
B) WLAN
C) token ring
D) Ethernet

Accepted Answer

IEEE Project 802.3 set specifications for Ethernet, which is a type of local area network. Choice A is incorrect as 15Base-5 refers to an old version of Ethernet. Choice B is incorrect as WLAN refers to wireless local area networks. Choice C is incorrect as token ring is a different type of local area network.

Question 10

That portion of the packet that does not include the header is called the _____.
A) frame
B) CRC
C) MAC
D) preamble

Accepted Answer

The frame refers to the portion of the packet that follows the header and includes both the actual data being transmitted and any additional information such as error correction codes. The CRC (Cyclic Redundancy Check) is a type of error detection code that is included in the frame. The MAC (Media Access Control) address is a unique identifier assigned to network devices, and is included in the header of the packet. The preamble is a series of bits added to the beginning of the packet to help synchronize the receiver's clock with the sender's clock.

Question 11

Known as the 5-4-3 rule, 10Base2 can connect up to five 200-meter segments using four repeaters, but only _____ segments can have devices connected to them.
A) two
B) three
C) four
D) five

Accepted Answer

The 5-4-3 rule states that a maximum of 5 segments can be connected using 4 repeaters, with a maximum of 3 populated segments (segments with devices connected) between any two repeaters. Therefore, only three segments can have devices connected to them, making choice B the correct answer.

Question 12

The most popular LAN architecture today is _____.
A) 10VG-AnyLAN
B) Ethernet
C) token bus
D) token ring

Accepted Answer

Ethernet is currently the most widely used LAN architecture, due to its high speed and low cost. 10VG-AnyLAN and token ring have become largely obsolete, while token bus is not widely used.

Question 13

A repeater knows which segment goes to which network device.

Accepted Answer

A repeater simply regenerates and amplifies the signal, it does not have any knowledge of which segment goes to which network device. That is the job of switches and routers.

Question 14

10Base-T is a _____ topology
A) star-wired bus
B) hub ring
C) star-wired ring
D) mesh token

Accepted Answer

10Base-T uses a star-wired bus topology where all devices are connected to a central hub in a star configuration.

Question 15

The Institute of Electrical and Electronic Engineers (IEEE) project to develop computer network architecture standards was called _____.
A) Xerox Extended
B) Cap One
C) Project 805
D) Project 802

Accepted Answer

Project 802 was the IEEE project to develop computer network architecture standards. It resulted in the development of several standards, including Ethernet (802.3), Wi-Fi (802.11), and Bluetooth (802.15.1). A, B, and C are not related to this project.

Question 16

A version of Ethernet called "Cheapernet" and "Thinnet" that uses a bus topology with CSMA/CD and requires thin coax cable is _____.
A) 10Base2
B) 100Base-T
C) TR-16
D) 5Base-55

Accepted Answer

The description matches 10Base2, which is also known as Cheapernet or Thinnet.

Question 17

The name of the first version of Ethernet, sometimes called Standard Ethernet, was more formally known as _____.
A) 10Base-T
B) XBase2
C) 100Base5
D) 10Base5

Accepted Answer

The first version of Ethernet was called 10Base5 or Thick Ethernet, which used thick coaxial cable as a transmission medium. Choice A, 10Base-T, is a later version of Ethernet that uses twisted pair cabling. Choice B, XBase2, is not a valid Ethernet standard. Choice C, 100Base5, is also not a valid Ethernet standard.

Question 18

An advantage of a 10Base-2 network is that it is difficult to find network errors.

Accepted Answer

This statement is false. It is actually easier to find network errors in a 10Base-2 network compared to other types of networks because it uses a bus topology where all computers are connected to the same cable. If there is a problem with the cable or a computer's network card, the entire network can be affected, making it easier to locate and diagnose the issue.

Question 19

_____ runs at 10 Mbps, uses CSMA/CD, and can support a total of 1,024 devices on the network.
A) 5Base-2
B) Token ring
C) 100Base-T
D) 10Base2

Accepted Answer

10Base2, also known as thin Ethernet or cheapernet, operates at 10 Mbps, uses Carrier Sense Multiple Access with Collision Detection (CSMA/CD) for data transmission, and can support up to 1,024 devices on a network segment.

Question 20

100VG-AnyLAN uses the demand priority channel access method instead of CSMA/CD.

Accepted Answer

100VG-AnyLAN uses the demand priority channel access method, where the station with the highest priority is given access to the network first. This is different from CSMA/CD, which uses a carrier sensing approach to avoid data collisions.
