Gaaffii 1

Which connector is most commonly used to terminate unshielded twisted-pair (UTP) network cables?

  1. A.BNC connector
  2. B.RJ45 connector
  3. C.ST connector
  4. D.SC connector
Deebii fi sababa agarsiisi

Deebii: B RJ45 connector

Sababa

RJ45 (Registered Jack 45) is the standard keyed connector used with UTP cabling to connect computers, switches, and routers.

Gaaffii 2

In a school computer lab in Hawassa, a student uses a keyboard to type data into a desktop computer. What type of data transmission mode does this represent?

  1. A.Simplex
  2. B.Half-duplex
  3. C.Full-duplex
  4. D.Duplex
Deebii fi sababa agarsiisi

Deebii: A Simplex

Sababa

In simplex mode, communication is unidirectional (one-way). Keyboards can only send input and traditional monitors can only receive output.

Gaaffii 3

Bluetooth radio frequency transceivers operate in the unlicensed Industrial, Scientific, and Medical (ISM) band centered at which frequency?

  1. A.900 MHz
  2. B.100 MHz
  3. C.2.4 GHz
  4. D.5.8 GHz
Deebii fi sababa agarsiisi

Deebii: C 2.4 GHz

Sababa

Bluetooth uses the unlicensed ISM frequency band centered at 2.4 gigahertz (GHz) to connect devices over short distances.

Gaaffii 4

What is the default network mask for a Class B IPv4 address?

  1. A.255.0.0.0
  2. B.255.255.0.0
  3. C.255.255.255.0
  4. D.255.255.255.255
Deebii fi sababa agarsiisi

Deebii: B 255.255.0.0

Sababa

The default subnet mask for Class B is 255.255.0.0 because the first two octets represent the network portion.

Gaaffii 5

A student in Addis Ababa wants to connect two computers directly together without using a switch or hub. Which cable wiring should the student use?

  1. A.Ethernet straight-through cable
  2. B.Thick coaxial cable
  3. C.Single-mode fiber cable
  4. D.Ethernet crossover cable
Deebii fi sababa agarsiisi

Deebii: D Ethernet crossover cable

Sababa

An Ethernet crossover cable is used to connect two similar devices directly together, such as computer to computer.

Gaaffii 6

In wireless transmission, what type of wave propagation occurs when high-frequency radio waves radiate upward into the ionosphere and are reflected back to Earth?

  1. A.Ground propagation
  2. B.Sky propagation
  3. C.Line-of-sight propagation
  4. D.Surface propagation
Deebii fi sababa agarsiisi

Deebii: B Sky propagation

Sababa

In sky propagation, radio waves radiate up into the ionosphere where they are reflected back to Earth, allowing long-distance transmission with lower power.

Gaaffii 7

In a cellular network, which switching office coordinates communication between all base stations, telephone central offices, and handles billing?

  1. A.Mobile Switching Center (MSC)
  2. B.Access Point (AP)
  3. C.Base Station (BS)
  4. D.Satellite Transponder
Deebii fi sababa agarsiisi

Deebii: A Mobile Switching Center (MSC)

Sababa

The Mobile Switching Center (MSC) is the computerized center that controls base stations, connects calls, records call information, and manages billing.

Gaaffii 8

Which fiber-optic cable connector uses a bayonet locking system and is commonly used for connecting cables to networking devices?

  1. A.Subscriber channel (SC)
  2. B.Mechanical Transfer Registered Jack (MT-RJ)
  3. C.Straight-tip (ST)
  4. D.Bayonet Neill-Concelman (BNC)
Deebii fi sababa agarsiisi

Deebii: C Straight-tip (ST)

Sababa

The straight-tip (ST) connector uses a bayonet locking system to attach fiber-optic cables to networking devices reliably.

Gaaffii 9

How does thin coaxial cable differ from thick coaxial cable in physical size and signal transmission?

  1. A.Thin coaxial cable is approximately 4 mm in diameter and typically carries baseband signals.
  2. B.Thin coaxial cable has a diameter between 6 and 18 mm and carries broadband signals.
  3. C.Thin coaxial cable provides superior noise isolation compared to thick coaxial cable.
  4. D.Thin coaxial cable carries signals entirely as light pulses.
Deebii fi sababa agarsiisi

Deebii: A Thin coaxial cable is approximately 4 mm in diameter and typically carries baseband signals.

Sababa

Thin coaxial cable is about 4 mm in diameter and typically carries baseband signals, whereas thick coaxial cable is 6 to 18 mm in diameter and carries broadband signals with better noise immunity.

Gaaffii 10

What is the exact orbital altitude above the surface of the Earth for a geostationary Earth orbit (GEO) satellite?

  1. A.Below 2,000 km
  2. B.Between 5,000 and 15,000 km
  3. C.35,786 km
  4. D.45,000 km
Deebii fi sababa agarsiisi

Deebii: C 35,786 km

Sababa

A GEO satellite has only one orbit at an altitude of exactly 35,786 km above the surface of the Earth.
