B. DHCP
C. IPSec
D. SMB
Answer
B. DHCP
Explanation
B. DHCP (Dynamic Host Configuration Protocol) is the correct option that provides client devices with an IP address.
DHCP is a network protocol used to automatically assign IP addresses, subnet masks, default gateways, and other network configuration parameters to client devices on a network. It eliminates the need for manual configuration and ensures efficient IP address management.
Here’s how DHCP works:
- When a client device (e.g., a computer or a smartphone) connects to a network, it broadcasts a DHCP Discovery message, requesting an IP address.
- A DHCP server on the network receives this request and responds with a DHCP Offer message, offering an available IP address from its pool of IP addresses.
- The client accepts the offered IP address by sending a DHCP Request message back to the server.
- Finally, the DHCP server confirms the IP address assignment by sending a DHCP Acknowledgment message to the client.
By providing IP addresses dynamically, DHCP ensures efficient use of IP addresses, especially in large networks where manual configuration would be impractical. It also simplifies network administration and reduces the chances of IP address conflicts.
