JNCIA-SEC: Juniper Networks Certified Associate – Security — Question 1

Your company has been assigned one public IP address. You want to enable Internet traffic to reach multiple servers in your DMZ that are configured with private
IP addresses.
In this scenario, which type of NAT would be used to accomplish this task?

Answer options

• A. source NAT
• B. destination NAT
• C. NAT without PAT
• D. static NAT

Correct answer: A

Explanation

Source NAT is the correct choice because it allows multiple servers with private IP addresses to share a single public IP address for outgoing traffic. The other options do not address the requirement of allowing multiple internal servers to communicate externally using one public IP, as destination NAT typically modifies the destination address for incoming traffic and static NAT maps a single private IP to a single public IP.
