A small business needs to set up a network to connect office computers, a server, and a printer.
Which computer network should be used?
A. Local area network (LAN)
B. Metropolitan area network (MAN)
C. Wide area network (WAN)
D. Campus area network (CAN)
Correct Answer: A. Local area network (LAN)
Explanation:
A LAN connects devices within a small area, such as an office or building, enabling efficient sharing of resources like printers and servers. It is cost-effective and ideal for small businesses.
Which scenario demonstrates the need for a campus area network (CAN)?
A. A small business needs to set up a network to connect office computers, a server, and a printer.
B. A business is expanding to have locations in 10 states and needs a network to span these locations.
C. A business has four locations throughout a city and needs to set up a network to share information among these locations.
D. A university needs to set up a network to connect systems among its many offices, classroom buildings, and dorm buildings.
Correct Answer: D. A university needs to set up a network to connect systems among its many offices, classroom buildings, and dorm buildings.
Explanation:
A CAN is designed to connect multiple buildings within a campus-like area, such as a university. It allows for centralized resource sharing across the campus.
A company needs to create a network to connect its main office, two office branches, and a factory, all located in various places throughout a city.
Which type of computer network is appropriate for this need?
A. Metropolitan area network (MAN)
B. Campus area network (CAN)
C. Local area network (LAN)
D. Wide area network (WAN)
Correct Answer: A. Metropolitan area network (MAN)
Explanation:
A MAN connects locations across a city or metropolitan area, making it ideal for organizations with facilities spread across a city.
A business is expanding to have locations in 10 states and needs a network to span these locations.
Which computer network should be used?
A. Metropolitan area network (MAN)
B. Local area network (LAN)
C. Wide area network (WAN)
D. Campus area network (CAN)
Correct Answer: C. Wide area network (WAN)
Explanation:
A WAN spans large geographical areas, such as states or countries, and is suitable for businesses with operations across multiple locations.
An organization is setting up a local area network to connect devices and share information within a manufacturing facility.
What is a benefit of using this type of network?
A. Supports a data transfer rate of 10 gigabits per second
B. Routes all traffic through a single server
C. Is well-suited for managing printers
D. Uses data redundancy to prevent data loss
Correct Answer: C. Is well-suited for managing printers
Explanation:
A LAN allows easy sharing and management of shared resources like printers within a localized environment.
A company is setting up a relatively small network and wants information on each device to be directly shareable with other devices.
What is the appropriate network architecture?
A. Peer-to-peer
B. Wide area
C. Client/server
D. File transfer
Correct Answer: A. Peer-to-peer
Explanation:
In a peer-to-peer network, each device can share resources directly with others without relying on a central server, making it suitable for small networks.
A business is designing a network for a new office location and wants information to be stored on central servers.
What is the network architecture that should be used in this situation?
A. Virtual private
B. Client/server
C. Peer-to-peer
D. File transfer
Correct Answer: B. Client/server
Explanation:
The client/server architecture centralizes data storage and management on servers, allowing client devices to access and retrieve data efficiently.
In order to best meet its needs for a new facility network, a business decided to implement a client/server architecture.
Which disadvantage is associated with this type of architecture?
A. The maximum number of devices supported is 50.
B. Central machine issues directly affect all linked devices.
C. Data transfer speeds are limited to 100 megabits per second.
D. All client computers share a single IP address.
Correct Answer: B. Central machine issues directly affect all linked devices.
Explanation:
In a client/server setup, if the central server experiences downtime or issues, all connected devices relying on it are affected, potentially halting operations.
As part of the design process for a new office computer network, a company needs a component that sends any received information to all other connected devices.
What is the component that the company needs?
A. Switch
B. Hub
C. Router
D. Server
Correct Answer: B. Hub
Explanation:
A hub is a basic networking device that broadcasts incoming data to all connected devices. This is simpler but less efficient compared to a switch.
A company is experiencing a latency issue with its website.
What does this type of issue refer to?
A. Incorrect web page element colors
B. Failure to convert analog signals to digital signals
C. An inability to transfer data
D. A lack of website availability
Correct Answer: C. An inability to transfer data
Explanation:
Latency refers to delays in data transmission, causing slow performance in tasks like website loading or file transfers. Addressing this issue involves optimizing the network.
A company is considering investing more resources in network performance monitoring tools.
What can the company expect these tools to do?
A. Throttle bandwidth for low-priority tasks
B. Configure network architecture
C. Monitor bandwidth issues
D. Predict network latency problems
Correct Answer: C. Monitor bandwidth issues
Explanation:
Network performance monitoring tools help track and diagnose bandwidth usage and related issues, ensuring the network operates efficiently.
