Which NAT method translates the source IP address in a packet to another IP address?
A . DNAT
B . SNAT
C . VIP
D . IPPOOL

Answer: B

Explanation:

The correct answer is: B. SNAT

SNAT (Source Network Address Translation), also known as MASQUERADE in iptables, translates the source IP address in a packet to another IP address. It is commonly used in scenarios where internal private IP addresses need to be translated to a single public IP address when accessing the Internet, for example. DNAT (Destination Network Address Translation) translates the destination IP address in a packet to another IP address. VIP (Virtual IP) is used to designate a single IP address that represents multiple servers for load balancing or high availability purposes. IPPOOL typically refers to a range of IP addresses that can be dynamically assigned to clients, such as in DHCP.
