The answer is that the endpoint has the default full-access policy. When you use the AWS CLI to describe a VPC endpoint and no policy document is displayed, it indicates that no custom policy was attached, so the endpoint defaults to allowing all actions from the principal. This is a key technical concept for Gateway endpoints, such as those for DynamoDB or S3, where omitting a policy automatically grants full access. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how VPC endpoint policies behave by default versus custom policies, and it’s a common trap to assume a missing policy means the endpoint is inactive or misconfigured. Remember the memory tip: “No policy shown? Full access is thrown.” This helps you recall that a blank policy field in the CLI output signals the default full-access policy, not an error or restriction.
ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Network Topology
A network engineer runs the above command to list VPC endpoints. The engineer notices that the second endpoint (vpce-0b2c3d4e5f6g7h8i9) does not have a policy document displayed. What does this indicate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The endpoint has the default full-access policy.
Option B is correct because by default, a Gateway endpoint for DynamoDB uses a full-access policy if no custom policy is specified. Option A is wrong because the endpoint is active. Option C is wrong because the missing policy field indicates no custom policy was set. Option D is wrong because DynamoDB endpoints do not require a policy; the default allows all actions.
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.
✗
The endpoint is configured to use an AWS managed policy that is not shown.
Why it's wrong here
AWS does not use managed policies for VPC endpoints; the policy is either custom or default.
✗
The endpoint is not active and needs to be recreated.
Why it's wrong here
The endpoint is listed, so it is active.
✗
The endpoint is for DynamoDB, which does not support endpoint policies.
Why it's wrong here
DynamoDB endpoints support policies; the default is full access.
✓
The endpoint has the default full-access policy.
Why this is correct
If no custom policy is specified, the default policy allows full access.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

TExam Day Tips
→Underline the problem statement mentally.
→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.

What is the correct answer to this question?
The correct answer is: The endpoint has the default full-access policy. — Option B is correct because by default, a Gateway endpoint for DynamoDB uses a full-access policy if no custom policy is specified. Option A is wrong because the endpoint is active. Option C is wrong because the missing policy field indicates no custom policy was set. Option D is wrong because DynamoDB endpoints do not require a policy; the default allows all actions.
