Correct Answer:<\/strong><\/h3>\n\n\n\n

A. To enable the switch to be managed remotely<\/strong><\/p>\n\n\n\n

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

A Layer 2 switch primarily operates at the Data Link Layer (Layer 2)<\/strong> of the OSI model<\/strong>, meaning it does not require an IP address to perform its main function: forwarding Ethernet frames based on MAC addresses<\/strong>. However, an IP address is necessary for remote management and administrative tasks.<\/p>\n\n\n\n

Why Does a Layer 2 Switch Need an IP Address?<\/strong><\/h4>\n\n\n\n
    \n
  1. Remote Management:<\/strong>\n
      \n
    • Without an IP address, an administrator would have to physically access the switch for configuration and troubleshooting.<\/li>\n\n\n\n
    • Assigning an IP address allows administrators to manage the switch remotely using protocols like Telnet, SSH, HTTP\/HTTPS, or SNMP<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Virtual LAN (VLAN) Management:<\/strong>\n
        \n
      • Managed switches often support VLANs<\/strong>, and each VLAN may require an interface (called an SVI – Switched Virtual Interface<\/strong>) to facilitate communication.<\/li>\n\n\n\n
      • An IP address can be assigned to the management VLAN (usually VLAN 1) to enable remote configuration.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Network Monitoring & Troubleshooting:<\/strong>\n
          \n
        • Administrators use ping, traceroute, and SNMP monitoring tools<\/strong> to check the status of the switch, which requires an IP address.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Integration with Higher Layers:<\/strong>\n
            \n
          • Some Layer 2 switches may support Layer 3 features<\/strong> (like inter-VLAN routing), requiring an IP for enhanced functionalities.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

            Why the Other Answers Are Incorrect?<\/strong><\/h3>\n\n\n\n
              \n
            • B. To enable the switch to function as a default gateway<\/strong> \u2192 Incorrect because a Layer 2 switch does not perform routing; this is a Layer 3 function.<\/li>\n\n\n\n
            • C. To enable the switch to receive frames from attached PCs<\/strong> \u2192 Incorrect because a switch forwards frames based on MAC addresses, not IP addresses.<\/li>\n\n\n\n
            • D. To enable the switch to send broadcast frames to attached PCs<\/strong> \u2192 Incorrect because switches send broadcast frames by default using MAC addresses.<\/li>\n<\/ul>\n\n\n\n

              Thus, the correct answer is A: “to enable the switch to be managed remotely.”<\/strong><\/p>\n\n\n\n
