Question 269 of 1,660
SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that will process sensitive financial transactions. The application must be deployed in a VPC with no public internet access. The application needs to send logs to Amazon CloudWatch Logs and store files in Amazon S3. Which set of actions should be taken to meet these requirements without allowing internet access?
⚠ Common exam trap
Test-takers frequently assume AWS PrivateLink can be used for both S3 and CloudWatch Logs uniformly, but S3 primarily uses Gateway VPC endpoints (not Interface endpoints) for private access, and PrivateLink is the mechanism for Interface endpoints only.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Gateway VPC endpoint for S3 and an Interface VPC endpoint for CloudWatch Logs
A Gateway VPC endpoint for S3 allows private connectivity to S3 without traversing the internet, using route table entries. An Interface VPC endpoint for CloudWatch Logs, powered by AWS PrivateLink, enables private HTTPS connections to the CloudWatch Logs API without requiring a NAT gateway or internet gateway. Together, these endpoints satisfy the requirement for a VPC with no public internet access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a Gateway VPC endpoint for S3 and an Interface VPC endpoint for CloudWatch Logs
Why this is correct
Gateway endpoints for S3 and Interface endpoints for CloudWatch Logs provide private connectivity within the VPC, no internet required.
- ✗
Place the application behind a public Application Load Balancer
Why it's wrong here
A public ALB would expose the application to the internet, violating the no-internet requirement.
- ✗
Set up a NAT gateway in a public subnet and route traffic through it
Why it's wrong here
A NAT gateway enables outbound internet access, which is not allowed because the requirement prohibits public internet access.
- ✗
Use AWS PrivateLink to connect to CloudWatch Logs and S3
Why it's wrong here
AWS PrivateLink is used for services in other AWS accounts. For CloudWatch Logs, you need an Interface endpoint; for S3, a Gateway endpoint. PrivateLink is not needed for these services.
