Trivia Quiz: Computer Tech Test For Entry Level!

The correct answer is "ipconfig" because it is a command used in Windows operating systems to display the IP configuration settings of a computer. By running this command in the command prompt, users can view information such as the IP address, subnet mask, default gateway, and DNS servers assigned to their computer's network interface. This command is useful for troubleshooting network connectivity issues or checking the current network settings.

A DHCP server is responsible for assigning automatic IP addresses to computers. This means that when a computer connects to a network, the DHCP server assigns it an IP address dynamically, eliminating the need for manual configuration. This allows the computer to communicate and access resources on the network without any manual intervention.

An IPv4 address is a 32-bit address used to identify devices on a network. Each section of the address consists of 8 bits, making a total of 32 bits. Therefore, the correct answer is 32.

To obtain an IP address from a DHCP server, the correct command to run is "ipconfig/renew." This command triggers the client to send a request to the DHCP server, asking for a new IP address lease. By running this command, the client can refresh its IP configuration and obtain a new IP address if available from the DHCP server.

The subnet mask of a slash notation /26 is 255.255.255.192. The slash notation represents the number of network bits in the subnet mask. In this case, /26 means that the first 26 bits of the subnet mask are set to 1, while the remaining 6 bits are set to 0. The subnet mask 255.255.255.192 has the first 26 bits set to 1, which matches the slash notation /26.

The subnet mask of a class B subnet is 255.255.0.0. This subnet mask allows for a larger number of hosts compared to a class C subnet mask (255.255.255.0) while still allocating a significant portion of the IP address for the network portion. With this subnet mask, the first two octets of the IP address represent the network portion, while the last two octets represent the host portion.

The default port of telnet is 23. Telnet is a network protocol used to establish a remote connection with a device over a network. It allows users to access and manage remote devices as if they were directly connected to them. The default port number for telnet is 23, which means that when establishing a telnet connection, the client and server will communicate through this port to exchange data and commands.

L2TP (Layer 2 Tunneling Protocol) is a VPN protocol that allows the creation of virtual private networks. It provides a secure and encrypted connection between two devices over the internet, allowing users to access private networks remotely. L2TP combines the best features of PPTP (Point-to-Point Tunneling Protocol) and L2F (Layer 2 Forwarding) to ensure confidentiality and data integrity. It is commonly used for remote access VPNs and is supported by a wide range of operating systems and devices.

HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that uses encryption to protect the data being transmitted. It is commonly used for secure online transactions, such as banking or online shopping. The correct answer is 443 because this is the port number that is typically used for HTTPS communication.

FTP (file transfer protocol) is a standard network protocol used for transferring files from one host to another over a TCP-based network. The correct answer is 21 because this is the well-known port number assigned to FTP. When a client initiates an FTP connection, it connects to port 21 on the server. This port is specifically reserved for FTP communication, allowing the client to establish a control connection with the server and exchange commands and data for file transfers.
