- A
Establish a VPN connection over the Direct Connect private VIF and route S3 traffic through the VPN.
Why wrong: This adds unnecessary overhead and does not leverage the public VIF for direct access.
- B
Use the public virtual interface and configure a route filter to only accept routes for the S3 service.
A public VIF provides access to AWS public services, and route filters can restrict which prefixes are advertised.
- C
Create a private virtual interface and attach it to the VPC.
Why wrong: A private VIF provides connectivity to VPC private IP addresses, not AWS public services like S3.
- D
Create a Direct Connect gateway and associate the public VIF with it.
Why wrong: Direct Connect gateway is for private VIFs to connect to multiple VPCs, not for public VIFs.
Quick Answer
The correct choice is to use the public virtual interface and configure a route filter to only accept routes for the S3 service. This works because a public VIF provides direct IP connectivity to AWS public services like S3, and by applying a route filter that accepts only S3-specific prefixes, you ensure on-premises traffic destined for S3 is forced over the Direct Connect link rather than traversing the public internet. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how public VIFs interact with route propagation and prefix filtering—a common trap is confusing public VIFs with private VIFs or Direct Connect gateways, which are designed for VPC connectivity, not public service access. Remember that public VIFs require explicit route filtering to isolate specific services; without it, the VIF would accept all AWS public prefixes. A helpful memory tip: “Public VIF + S3 filter = direct path, no internet detour.”
ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. 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 company has a Direct Connect connection with a public virtual interface (VIF) to access AWS public services. They want to ensure that all traffic to Amazon S3 from on-premises uses the Direct Connect connection instead of the internet. Which configuration is required?
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
Use the public virtual interface and configure a route filter to only accept routes for the S3 service.
Option B is correct because using a public VIF with a route filter that only allows S3 prefixes ensures traffic to S3 uses Direct Connect. Option A is wrong because a private VIF is for private IP connectivity to VPCs, not public services. Option C is wrong because a VPN over Direct Connect is unnecessary and adds complexity. Option D is wrong because a Direct Connect gateway is used for private VIFs to multiple VPCs, not public VIFs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
