This DVA-C02 practice question tests your understanding of security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A Lambda function in a VPC must retrieve secrets from Secrets Manager without traversing the public internet. Which configuration should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
An interface VPC endpoint for Secrets Manager with appropriate security groups
An interface VPC endpoint (AWS PrivateLink) for Secrets Manager allows Lambda functions within a VPC to securely retrieve secrets using private IP addresses, without traversing the public internet. This is achieved by creating an elastic network interface in the VPC subnet with a security group that controls access, ensuring traffic stays within the AWS network.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
A public NAT gateway only
Why it's wrong here
This does not meet the stated requirement as directly as the correct option.
✗
An internet gateway attached to the Lambda subnet
Why it's wrong here
This does not meet the stated requirement as directly as the correct option.
✗
A VPC peering connection to every AWS region
Why it's wrong here
This does not meet the stated requirement as directly as the correct option.
✓
An interface VPC endpoint for Secrets Manager with appropriate security groups
Why this is correct
Correct for the stated requirement.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse NAT gateways or internet gateways as solutions for private service access, not realizing that AWS PrivateLink endpoints are the correct mechanism to keep traffic within the AWS backbone.
Detailed technical explanation
How to think about this question
Interface VPC endpoints use AWS PrivateLink to privately connect a VPC to supported AWS services via elastic network interfaces (ENIs) with private IPs. DNS resolution for the service endpoint (e.g., secretsmanager.us-east-1.amazonaws.com) is automatically updated to resolve to these private IPs when the 'Enable Private DNS Name' option is enabled. This ensures that Lambda functions using the default SDK endpoint remain within the AWS network, avoiding NATgateway costs and internet egress.

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
