An IP Address (or IPV4 number) is a set of four numbers each within what range?
- A.
0 To 1000
- B.
0 To 255
- C.
20 To 235
- D.
10 To 999
Correct Answer
B. 0 To 255Explanation
An IP address (or IPV4 number) is a set of four numbers, each ranging from 0 to 255. This is because an IP address is a 32-bit number, divided into four octets, and each octet can have a value from 0 to 255. This range allows for a total of 4,294,967,296 unique IP addresses to be assigned.Rate this question:

What kind of technology do wireless networks use in order to send information?
- A.
Radio Waves
- B.
Infra-Red
- C.
Microwave
- D.
X Rays
Correct Answer
A. Radio WavesExplanation
Wireless networks use radio waves to send information. Radio waves are electromagnetic waves that have long wavelengths and low frequencies. They are able to carry signals over long distances and can easily penetrate through walls and other obstacles. This makes radio waves the ideal technology for wireless communication, allowing devices to connect to the internet and transmit data without the need for physical cables.Rate this question:

Which are the basic protocol intranets use?
- A.
HTTP
- B.
Telnet
- C.
DHCP
- D.
TCP/IP
Correct Answer
D. TCP/IPExplanation
Intranets use the TCP/IP protocol as a basic protocol. TCP/IP is a suite of communication protocols that enables the transfer of data over networks. It is widely used in both local area networks (LANs) and wide area networks (WANs). TCP/IP provides reliable and efficient data transmission by breaking data into packets and ensuring their delivery to the intended destination. It also includes protocols like IP (Internet Protocol) for addressing and routing, and TCP (Transmission Control Protocol) for establishing and maintaining connections between devices. Overall, TCP/IP is the fundamental protocol used in intranets for seamless communication and data transfer.Rate this question:

What mail protocol allows a computer to work with mail directly on the server?
- A.
SMTP
- B.
IMAP
- C.
POP3
- D.
HTTP
Correct Answer
B. IMAPExplanation
IMAP (Internet Message Access Protocol) is a mail protocol that allows a computer to work with mail directly on the server. Unlike POP3 (Post Office Protocol version 3), which downloads emails to the device and removes them from the server, IMAP keeps the emails on the server and allows users to access and manage them from multiple devices. This makes it convenient for users who access their emails from different devices as they can synchronize their mailbox and have consistent access to their emails. SMTP (Simple Mail Transfer Protocol) is used for sending emails, while HTTP (Hypertext Transfer Protocol) is used for web browsing.Rate this question:

What address do manufacturers of network adapters burn into their products, in order to uniquely identify them?
- A.
Memory Address
- B.
Base Address
- C.
IP Address
- D.
MAC address
Correct Answer
D. MAC addressExplanation
Manufacturers of network adapters burn the MAC address into their products in order to uniquely identify them. The MAC address, also known as the Media Access Control address, is a unique identifier assigned to network interfaces. It is a hardware address that is permanently assigned to the network adapter during manufacturing. This address is used by the network devices to communicate with each other on a local network. Unlike IP addresses, which can change, the MAC address remains constant and helps in ensuring the proper delivery of data packets within a network.Rate this question:

What servers provide network firewall, connection sharing, and caching technology for networks?
- A.
FTP Servers
- B.
Proxy Servers
- C.
DNS Servers
- D.
Web Servers
Correct Answer
B. Proxy ServersExplanation
Proxy servers provide network firewall, connection sharing, and caching technology for networks. A proxy server acts as an intermediary between clients and other servers. It can filter and block certain types of network traffic, providing a firewall to protect the network. It can also share internet connections among multiple devices, allowing them to access the internet through a single connection. Additionally, proxy servers can cache frequently accessed web content, reducing bandwidth usage and improving network performance. Therefore, proxy servers are the correct answer for this question.Rate this question:

What value could be expressed in bits per second?
- A.
Time To Live
- B.
File Size
- C.
Last Update Time
- D.
Bandwidth
Correct Answer
D. BandwidthExplanation
Bandwidth is the measure of the amount of data that can be transmitted over a network connection in a given amount of time. It is commonly expressed in bits per second (bps). Therefore, bandwidth is the value that can be expressed in bits per second. Time To Live, File Size, and Last Update Time are not typically measured in bits per second.Rate this question:

How many times faster is Fast Ethernet than standard Ethernet?
- A.
100 Times
- B.
10 Times
- C.
5 Times
- D.
2 Times
Correct Answer
B. 10 TimesExplanation
Fast Ethernet is 10 times faster than standard Ethernet. This means that the data transfer rate of Fast Ethernet is 10 times higher than that of standard Ethernet. This increase in speed allows for faster and more efficient communication and data transmission between devices on a network.Rate this question:

What is the term defining a malicious attempt to render a networked system unusable?
- A.
Ping
- B.
DoS
- C.
Telnet
- D.
Traceroute
Correct Answer
B. DoSExplanation
A Denial of Service (DoS) attack is a malicious attempt to render a networked system unusable. This is typically achieved by overwhelming the targeted system with a flood of illegitimate requests or by exploiting vulnerabilities to exhaust its resources. The goal of a DoS attack is to disrupt the normal functioning of the system, making it unable to respond to legitimate users or perform its intended functions.Rate this question:

- A.
Network Office Solution
- B.
Network Optical Support
- C.
Network Octet Storage
- D.
Network Operating System
Correct Answer
D. Network Operating SystemExplanation

What does the acronym ARP stand for?
- A.
Address Resolution Protocol
- B.
Address Remap Protocol
- C.
Address Resolve Protocol
- D.
Address Range Protocol
Correct Answer
A. Address Resolution ProtocolExplanation
The correct answer is Address Resolution Protocol. ARP is a protocol used to map an IP address to a physical or MAC address on a local network. It allows devices to communicate with each other by resolving the IP address of a destination device to its corresponding MAC address. This is necessary because devices on a network communicate at the MAC address level, and ARP helps in identifying the MAC address of a device based on its IP address.Rate this question:

What does PPP stand for?
- A.
Peer-to-Point Protocol
- B.
Point-to-Point Protocol
- C.
Peer-to-Peer Protocol
- D.
Point-to-Peer Protocol
Correct Answer
B. Point-to-Point ProtocolExplanation
PPP stands for Point-to-Point Protocol. This protocol is used to establish a direct connection between two network nodes, typically over a serial interface. It is commonly used in dial-up connections and is responsible for establishing and maintaining the link between the sender and receiver. The other options, Peer-to-Point Protocol and Peer-to-Peer Protocol, do not accurately represent the correct acronym for PPP.Rate this question:
