Google Cloud Professional Cloud Network Engineer — Question 246

You want to configure a NAT to perform address translation between your on-premises network blocks and GCP.
Which NAT solution should you use?

Answer options

• A. Cloud NAT
• B. An instance with IP forwarding enabled
• C. An instance configured with iptables DNAT rules
• D. An instance configured with iptables SNAT rules

Correct answer: A

Explanation

Cloud NAT is the appropriate choice for performing address translation as it is a fully managed service that simplifies NAT configuration in GCP. The other options involve setting up NAT on instances, which requires more management, complexity, and is not as efficient as using Cloud NAT.
