Final answer:
Matching the correct DHCP message types with their respective purposes involves identifying the action associated with each type, such as renewing a lease for DHCPREQUEST, releasing a lease for DHCPRELEASE, locating DHCP servers with DHCPDISCOVER, and confirming a lease with DHCPACK.
Step-by-step explanation:
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to dynamically assign IP addresses to devices on a network. Matching the purpose with its DHCP message type:
- a) DHCPREQUEST - Renewing lease: This message type is used by a client to request an IP address lease from the DHCP server. It's also used to renew an existing lease.
- b) DHCPRELEASE - Releasing lease: When a client is shutting down or no longer needs an IP address it has been assigned, it sends a DHCPRELEASE message to the DHCP server to terminate the lease.
- c) DHCPDISCOVER - Locating DHCP servers: This message is broadcast by a client when it is connected to a network to discover available DHCP servers.
- d) DHCPACK - Confirming lease: The DHCPACK message is sent by the server to the client to acknowledge a DHCPREQUEST and provide IP configuration parameters.
