What is the minimum number of computers needed for a computer network?
- A.
1
- B.
2
- C.
5
- D.
10
Correct Answer
B. 2Explanation
A minimum of two computers is needed for a computer network because a network requires at least two devices to establish a connection and communicate with each other. With only one computer, there would be no other device to connect to, resulting in no network. Therefore, two computers are necessary for a basic computer network.Rate this question:

What is a privately-owned network whose access is restricted to authorized peronnel called?
- A.
Homogeneous Network
- B.
Internetwork
- C.
Intranetwork
- D.
Local Area Network (LAN)
Correct Answer
C. IntranetworkExplanation
An intranetwork is a privately-owned network that restricts access to authorized personnel only. It is a network that is specifically designed for internal use within an organization, allowing employees to securely share information and resources. Unlike an internetwork, which connects multiple networks together, an intranetwork is confined to a single organization. It is also different from a local area network (LAN), as a LAN refers to a network that covers a small geographical area, whereas an intranetwork can span multiple locations. Therefore, the correct answer is intranetwork.Rate this question:

How many users are nomally in a peer to peer network?
- A.
2-10
- B.
10-50
- C.
50-250
- D.
250-1000
Correct Answer
A. 2-10Explanation
In a peer-to-peer network, the number of users typically ranges from 2 to 10. This means that there are usually only a small number of users connected to the network at any given time. This range is common for peer-to-peer networks because they are often used for small-scale file sharing or collaboration among a small group of individuals. Having a limited number of users helps to ensure efficient and effective communication and sharing of resources within the network.Rate this question:

- D.
250-1000
Correct Answer
B. 10-50Explanation
A single server network typically refers to a network setup where there is only one server responsible for managing and providing resources to a group of users. The range of 10-50 users suggests that this type of network is designed to support a relatively small number of users. This range allows for a sufficient number of users to connect to the server and utilize its resources without overwhelming it. It strikes a balance between having enough users to make the network efficient and cost-effective, while also ensuring that the server can handle the workload effectively.Rate this question:

- C.
131.10.230.0
- D.
255.255.255.0
Correct Answer
C. 131.10.230.0Explanation
The network ID of an IP address is obtained by setting all the host bits to zero. In this case, the given IP address is 131.10.230.120/24, where the subnet mask is /24. This means that the first 24 bits of the IP address are the network bits, and the remaining 8 bits are the host bits. Therefore, to find the network ID, we set the host bits to zero, resulting in the network ID of 131.10.230.0.Rate this question:

Correct Answer
A. GetExplanation
The operational SNMP message that asks for a specific instance of management information is the "Get" message. This message is used to retrieve the value of a specific variable or object from a managed device. It allows the SNMP manager to request specific information from the SNMP agent by specifying the Object Identifier (OID) of the desired variable. The SNMP agent then responds with the current value of that variable.Rate this question:

Correct Answer
D. GetNextExplanation
The correct answer is GetNext. GetNext is an operational SNMP message that is used to retrieve multiple pieces of information with minimal overhead. It allows the SNMP manager to retrieve the next variable in the MIB (Management Information Base) table, which makes it efficient for retrieving sequential data. By using GetNext, the manager can retrieve multiple variables in a single request without having to send separate Get requests for each variable. This reduces the overhead and improves the efficiency of the SNMP communication.Rate this question:
