Tcp And Udp Port Numbers Quiz

Port 20 is commonly used for FTP (File Transfer Protocol) TCP data sending, allowing for the transfer of files between a client and a server.

Port 21 is commonly used for FTP (File Transfer Protocol) which is used for transferring files between a client and server. HTTP uses port 80, SSH uses port 22, and SMTP uses port 25.

The correct answer is SSH-Secure Shell-TCP, as it is commonly used for secure remote access to systems.

Port 23 is often used for Telnet, which is a text-based communication protocol. SSH (Secure Shell) typically uses port 22, HTTP (Hypertext Transfer Protocol) uses port 80, and FTP (File Transfer Protocol) uses ports 20/21.

Port 25 is commonly used for SMTP, which is responsible for sending email messages over a network. While other protocols like HTTP, FTP, and SSH use different ports and methods for data transfer, SMTP specifically handles email communication.

Port 80 is commonly used by web servers to send and receive HTTP messages over TCP. FTP uses Port 21, SMTP uses Port 25, and SSH uses Port 22 for their respective services.

Port 110 is commonly used for POP3, which is used for receiving emails from a mail server. SMTP is used for sending emails, HTTP for web browsing, and FTP for file transfers, making them incorrect choices.

Port 443 is commonly used for HTTPS communication which is secured by SSL (Secure Socket Layer) protocol over TCP (Transmission Control Protocol). HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol) are commonly associated with different port numbers and are not typically used on Port 443.

Port 67 is specifically designated for DHCP servers to listen for client requests. DHCP is used to assign IP addresses dynamically to devices in a network.

Port 68 is commonly used for DHCP (Dynamic Host Configuration Protocol) client communications, allowing devices to obtain IP addresses and other network configuration information automatically.

Port 69 is used by TFTP, which is a simple file transfer protocol that operates over UDP. HTTP, FTP, and SMTP each use different ports and protocols for their respective functionalities.

Port 161 is commonly used by SNMP (Simple Network Management Protocol) for network monitoring and management tasks.

Port 53 is typically used for DNS (Domain Name Service) over TCP. This service translates domain names to IP addresses, allowing users to access websites and other resources on the internet.

Port 24 is commonly used for private mail systems TCP, not for HTTP, FTP, or SSH services.

Port 24 is commonly associated with private mail systems using the UDP protocol. Ports 80, 53, and 123 are commonly used for HTTP, DNS, and NTP protocols respectively.

Port 119 is commonly associated with NNTP (Network News Transfer Protocol) TCP, which is used for transferring Usenet articles between servers. SMTP uses port 25, HTTP uses port 80, and FTP uses port 21.

Port 123 is commonly associated with NTP (Network Time Protocol) which is used for time synchronization on computer networks.
