The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is a. Ports 25, 110, and 143<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

When configuring email client\/server applications, certain ports are used to facilitate the sending and receiving of email messages. Here’s a breakdown of each port in option a<\/strong>:<\/p>\n\n\n\n

    \n
  1. Port 25 (SMTP)<\/strong> \u2013 This port is primarily used for sending email from one server to another using the Simple Mail Transfer Protocol (SMTP)<\/strong>. SMTP is the protocol responsible for transferring outgoing emails between servers and for relaying messages. Despite being one of the oldest and most widely used ports for email, Port 25<\/strong> is often blocked by Internet Service Providers (ISPs) to prevent spam and unauthorized email use. SMTP over Port 587<\/strong> or Port 465<\/strong> (for SSL\/TLS encryption) is more common in modern configurations for security reasons.<\/li>\n\n\n\n
  2. Port 110 (POP3)<\/strong> \u2013 This port is used for Post Office Protocol version 3 (POP3)<\/strong>, which is one of the older protocols used by email clients to retrieve emails from the server. POP3<\/strong> allows users to download email messages to their local device, where they are typically stored and deleted from the server. POP3 operates over Port 110<\/strong> without encryption by default, but Port 995<\/strong> is used when encrypted with SSL.<\/li>\n\n\n\n
  3. Port 143 (IMAP)<\/strong> \u2013 The Internet Message Access Protocol (IMAP)<\/strong> is a more modern and flexible protocol used by email clients to access email messages stored on a mail server. IMAP<\/strong> allows users to read, organize, and delete messages directly on the server without needing to download them first, which makes it more useful for those who want to access their email from multiple devices. Port 143<\/strong> is the default port for IMAP, and Port 993<\/strong> is used for encrypted connections using SSL\/TLS.<\/li>\n<\/ol>\n\n\n\n

    Why other options are incorrect:<\/h3>\n\n\n\n
      \n
    • b. Ports 21, 22, and 23<\/strong>: These ports are for FTP (Port 21), SSH (Port 22), and Telnet (Port 23), which are not used for email.<\/li>\n\n\n\n
    • c. Ports 22, 110, and 143<\/strong>: Port 22 (SSH) is used for secure remote access to servers, not for email.<\/li>\n\n\n\n
    • d. Ports 110 and 300<\/strong>: There is no standard email-related service using Port 300.<\/li>\n<\/ul>\n\n\n\n

      Thus, Ports 25, 110, and 143<\/strong> are the correct ones for email-related applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
