Common Network Ports Quiz

Network Protocols

• FTP (File Transfer Protocol) is used for transferring files between hosts over a network.
• SMTP (Simple Mail Transfer Protocol) is commonly configured on mobile devices and email clients for sending mail.
• SSH (Secure Shell) provides console access to devices remotely.
• SMTP is used for transferring email between mail servers.
• SMB (Server Message Block) is commonly used for file transfers and printer sharing in Windows.
• DHCP (Dynamic Host Configuration Protocol) is used for automated configuration of IP address, subnet mask, and other options.
• SNMP (Simple Network Management Protocol) is used for gathering statistics from network devices.
• DNS (Domain Name System) is used for converting domain names to IP addresses.
• SSH is used for encrypted console access.
• HTTPS (Hypertext Transfer Protocol Secure) is used for web server communication with encryption.
• POP3 (Post Office Protocol version 3) is used for receiving emails from an email server.
• LDAP (Lightweight Directory Access Protocol) is used for storing and retrieving information in a network directory.
• SMTP is used for transferring email between mail clients and the email server.
• Bonjour is used for finding Mac OS services by name.
• RDP (Remote Desktop Protocol) is used for graphical display of remote devices.
• FTP is associated with tcp/20 and tcp/21 for file transfer.
• SSH is associated with tcp/22 for encrypted console access.
• SMTP is associated with tcp/25 for transferring email between mail servers.
• DNS is associated with udp/53 and tcp/53 for converting domain names to IP addresses.
• DHCP is associated with udp/67 and udp/68 for automated configuration of IP address, subnet mask, and other options.
• SMB is associated with tcp/445 for file transfers and printer sharing in Windows.
• POP3 is associated with tcp/110 for receiving emails from an email server.
• HTTPS is associated with tcp/443 for web server communication with encryption.
• FTP uses tcp/20 for active mode data transfer and tcp/21 for control.
• RDP is associated with tcp/3389 for graphical display of remote devices.
• SSH provides encrypted communication link over tcp/22.
• LDAP is associated with tcp/389 for storing and retrieving information in a network directory.
• SMTP is commonly configured on mobile devices and email clients for sending mail over tcp/25.
• SNMP is used for gathering metrics and managing network devices and is associated with udp/161.
• DNS converts names to IP addresses over udp/53.
• AFP (Apple Filing Protocol) is used for Mac OS file transfers and is associated with tcp/548.
• FTP is not the best choice for production systems due to in-the-clear communication.
• SSH provides console access to devices remotely.
• SMTP is used for transferring email between mail servers.
• SNMP is used for gathering statistics from network devices.
• LDAP is used for storing and retrieving information in a network directory.
• RDP is used for graphical display of remote devices.
• SMTP is used for transferring email between mail clients and the email server.
• DHCP is used for automated configuration of IP address, subnet mask, and other options.
