Correct Answer: DHCP

DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses and other network configuration settings to devices on a network.

Correct Answer: DNS

DNS (Domain Name System) is responsible for resolving domain names to their corresponding IP addresses in a network, allowing users to access websites and services.

Correct Answer: traceroute

The traceroute command on a Linux machine is used to trace the route taken by packets to reach a destination, showing the intermediate hops along the path.

Correct Answer: To distribute traffic across multiple servers

A load balancer distributes network traffic across multiple servers to improve performance and ensure that no single server becomes overwhelmed.

Correct Answer: ipconfig /all

The ipconfig /all command displays detailed network information, including the MAC address of network interfaces on a Windows machine.

Correct Answer: 802.11a

The 802.11a wireless networking standard operates exclusively in the 5 GHz frequency band, providing faster speeds but shorter range compared to 2.4 GHz networks.

Correct Answer: Transport layer

The Transport layer (Layer 4) is responsible for managing end-to-end connections, error checking, and ensuring reliable data transmission between devices.

Correct Answer: ifconfig

The ifconfig command on a Linux system is used to configure and view network interface settings, such as the IP address, netmask, and gateway.

Correct Answer: To ensure that packets do not circulate indefinitely in the network

The TTL (Time to Live) field in an IP packet specifies the maximum number of hops the packet can take before being discarded, preventing it from circulating indefinitely.

Correct Answer: SSH

SSH (Secure Shell) is used for secure remote management and login to network devices, encrypting the data transmitted during the session.
