Oracle Cloud Infrastructure Foundations 2020 Associate — Question 23

Which gateway can be used to provide internet access to an Oracle Cloud infrastructure compute instance in a private subnet?

Answer options

• A. Internet Gateway
• B. NAT Gateway
• C. Service Gateway
• D. Dynamic Routing Gateway

Correct answer: B

Explanation

The correct answer is B, as a NAT Gateway allows outbound internet access for instances in a private subnet while keeping them secure from inbound traffic. The Internet Gateway is not suitable for private subnets, a Service Gateway is used for accessing Oracle services, and a Dynamic Routing Gateway is for connecting to on-premises networks, not for internet access.
