1. Which category of network components includes wires and cables used in a wired network?
- media
- peripherals
- devices
- hosts
Explanation: Network media describes the cables and wires used in wired networks and the radio frequency waves used in wireless networks.
2. Which statement describes the physical topology for a LAN?
- It defines how hosts and network devices connect to the LAN.
- It describes whether the LAN is a broadcast or token-passing network.
- It shows the order in which hosts access the network.
- It depicts the addressing scheme that is employed in the LAN.
Explanation: A physical topology defines the way in which computers and other network devices are connected to a network.
3. Which wireless technology is used on smart phones to transmit data to another device within very close proximity?
- Bluetooth
- 3G/4G
- NFC
- Wi-Fi
Explanation: Near Field Communications (NFC) is a wireless technology that enables data to be exchanged by devices that are in very close proximity to each other.
4. Which IP configuration parameter provides the IP address of a network device that a computer would use to access the internet?
- DNS server
- subnet mask
- host IP address
- default gateway
Explanation: The types of IP configuration on a host device include these:
- IP address – identifies the host on the network.
- Subnet mask – identifies the network on which the host is connected.
- Default gateway – identifies the networking device that the host uses to access the Internet or another remote network.
- DNS server – identifies the server that is used to translate a domain name into an IP address.
5. A traveling sales representative uses a cell phone to interact with the home office and customers, track samples, make sales calls, log mileage, and upload/download data while at a hotel. Which internet connectivity method would be a preferred method to use on the mobile device due to the low cost?
- DSL
- cellular
- cable
- Wi-Fi
Explanation: Mobile devices typically use either the cellular network or a Wi-Fi network to connect to the internet. The Wi-Fi connection is preferred because it uses less battery power and is free in many places.
6. Refer to the exhibit. Which type of topology drawing is shown?
- logical
- physical
Explanation: The two types of network drawings are the logical and the physical. A logical drawing has labeled icons that identify network devices. A physical drawing shows the location of each device.
7. When the growth of a small network is being planned, which design element will include the physical and logical topology of the network?
- network documentation
- budget
- traffic analysis
- device inventory
Explanation: Many types of information are required by network administrators when planning for network growth. One element that is needed is an accurate logical and physical topology of the current network. These topologies can be found in the network documentation.
8. What are two recommendations for an organization that is implementing network device naming standards? (Choose two.)
- A device name should be more than 8 characters.
- Device names should be in a consistent format.
- A device name, especially for PCs, should include an IP address.
- Each device should have a unique, meaningful name.
- Each device name should include upper/lower case letters, numbers, and symbols.
Explanation: The network device naming convention in an organization should include a standard and consistent format that conveys meaningful information that is useful when locating devices on a network. Because of the fact that the IP address may change, an IP address on a PC is not commonly part of the name. The length of the name varies. The format of the device name is company-dependent.
9. Which type of technology is used to provide digital data transmissions over cell phone networks?
- Bluetooth
- NFC
- 4G
- Wi-Fi
Explanation: 3G, 4G, and 4G-LTE are technologies that are used to provide enhanced cell phone networks that are capable of fast data transmission.
10. Which wireless technology can be used to connect wireless headphones to a computer?
- NFC
- 4G-LTE
- Bluetooth
- Wi-Fi
Explanation: Bluetooth is a low-power, short range wireless technology that provides connectivity for accessories such as speakers, headphones, and microphones.
11. A teenager has asked the grandparents for a specific type of mobile technology. The grandparents do not remember the specific name of the device, but remember that the teenager wants to receive a cell phone call on it. Which technology is likely to be the one the teenager wants?
- VR headset
- e-reader
- smart watch
- GPS
Explanation: A smart watch commonly has many of the same functions of a smart phone such as receiving/placing calls, playing online games, and using applications such as a calculator or geolocator.
12. What is a technology used in a cellular telephone network?
- fiber-optic
- Wi-Fi
- Bluetooth
- Global System for Mobile Communications (GSM)
Explanation: The most common type of cellular telephone network is called Global System for Mobile Communications or GSM network and it relays a voice signal from one tower to another tower, until it is delivered to a destination.
