02 Communication Random Qs [2]

Which of the following best describes the client-server model of networked computers?

• Each computer acts as both a provider and consumer of resources, sharing them directly with other computers.

• There is no central authority, and each computer is responsible for its own security and resource management.

• A dedicated server provides resources and services, while client computers request and utilize these resources.

• Computers are connected in a linear sequence, and data is passed from one to the next until it reaches its destination.

What is a key implication of using a wired network, such as Ethernet, compared to a wireless network like Wi-Fi?

• Wired networks offer greater flexibility in device placement and mobility.

• Wired networks provide more reliable and faster data transfer speeds

• Wireless networks are inherently more secure as they do not rely on physical cables that can be tapped.

• Setting up a wired network is usually simpler and requires less specialised hardware than a wireless network.

Which piece of hardware connects multiple devices within a LAN and forwards data based on MAC addresses?

• Modem

• Router

• Switch

• Firewall

Which piece of hardware controls network traffic based on predefined rules within a LAN?

• Modem

• Router

• Switch

• Firewall

What is the primary benefit of using subnetting in a network?

• To increase the size of the broadcast domain, allowing more devices to communicate directly.

• To eliminate the need for routers within the local network.

• To divide a larger network into smaller, more manageable subnetworks, which can improve security, reduce network traffic, and simplify administration.

• To allow devices with private IP addresses to directly communicate with the internet without Network Address Translation (NAT).

What is a fundamental difference between a public IP address and a private IP address?

• Private IP addresses are used for communication within a LAN and are globally unique, while public IP addresses are used for direct internet access and are not unique.

• Public IP addresses are static and do not change, while private IP addresses are dynamic and can be reassigned by a DHCP server.

• A public IP address is assigned to a device for direct communication over the internet, whereas a private IP address is used for internal communication within a LAN.

• Public IP addresses offer more security features and are less susceptible to unauthorized access compared to private IP addresses.

Which of the following best describes the key characteristic of the client-server network model?

• a) All computers have equal capabilities and share resources directly with each other

• b) Network administration is distributed among all connected computers.

• c) A central server provides services and resources that are accessed by client computers

• Computers are connected in a ring topology, and data travels sequentially through each device.

Which of the following is generally considered an advantage of a wired network over a wireless network?

• Greater ease of adding new devices to the network

• Increased mobility and flexibility for users.

• Lower initial hardware and installation costs.

• More consistent and potentially higher data transfer speeds

Which piece of hardware in a Local Area Network (LAN) is primarily responsible for forwarding data packets between different networks?

• Router

• Modem

• Switch

• Network Interface Card

Why is subnetting considered beneficial for network security?

• It allows all devices to be on the same broadcast domain, simplifying security management.

• It automatically encrypts all network traffic

• It isolates network segments, limiting the impact of security breaches to a smaller portion of the network

• It allows direct communication between devices with private IP addresses and the internet.
