- A
The private VIF can be used without a virtual interface termination device on the customer side
Why wrong: A router is required to terminate the VIF.
- B
The public VIF can be used to connect to a VPC via a Direct Connect Gateway
Why wrong: Public VIF does not connect to VPCs; that's private VIF.
- C
The private VIF can be used to access Amazon S3 over a private IP address
Why wrong: Private VIF is for VPC access, not public services.
- D
The Direct Connect Gateway allows the private VIF to connect to multiple VPCs in different AWS Regions
Direct Connect Gateway enables multi-region connectivity.
- E
The public VIF can be used to access AWS public services such as Amazon S3 over Direct Connect
Public VIF provides access to public endpoints.

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 network engineer is designing a Direct Connect solution with a public VIF and a private VIF. The private VIF will connect to a VPC via a Direct Connect Gateway. Which TWO of the following statements are correct regarding this setup? (Choose 2.)
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
✓
The Direct Connect Gateway allows the private VIF to connect to multiple VPCs in different AWS Regions
Option D is correct because a Direct Connect Gateway enables a private VIF to connect to multiple VPCs, even across different AWS Regions, by acting as a transit hub. The gateway uses a single private VIF to route traffic to up to 10 VPCs (by default) in any region, provided the VPCs are associated via virtual private gateways and the appropriate route tables are configured.
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
The ANS-C01 exam often tests the misconception that a public VIF can be used to connect to a VPC via a Direct Connect Gateway, but in reality, Direct Connect Gateway only supports private VIFs, and public VIFs are strictly for accessing AWS public services over public IP addresses.
Detailed technical explanation
How to think about this question
Under the hood, a Direct Connect Gateway uses a single BGP session over the private VIF to advertise a set of prefixes (from associated VPCs) to the customer router, and it performs inter-region routing by leveraging the AWS global backbone. A subtle behavior is that traffic between a Direct Connect Gateway and a VPC in a different region incurs data transfer charges, but it avoids traversing the public internet. In a real-world scenario, a company with VPCs in us-east-1 and eu-west-1 can use one Direct Connect Gateway and one private VIF to provide hybrid connectivity to both regions, simplifying network design.
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.
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 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.
