- A
A NAT gateway in each Availability Zone.
Why wrong: NAT gateways are for outbound internet, not Direct Connect.
- B
Two separate Direct Connect connections from different providers or locations.
Redundant physical connections prevent a single point of failure.
- C
BGP with multiple sessions and AS-path prepending for route preference.
BGP allows traffic to fail over and control routing preferences.
- D
A VPN connection as a backup to the Direct Connect.
A VPN can serve as a failover path if Direct Connect goes down.
- E
A single Direct Connect connection with multiple VLANs.
Why wrong: VLANs do not provide physical redundancy.

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.
An organization is designing a hybrid network using AWS Direct Connect with a private VIF. They want to ensure high availability and failover. Which THREE components should be part of the design?
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
✓
Two separate Direct Connect connections from different providers or locations.
Option B is correct because using two separate Direct Connect connections from different providers or locations ensures physical diversity, eliminating single points of failure. This design meets the high availability requirement by providing redundant paths for traffic, even if one connection or provider experiences an outage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

- ✗
A single Direct Connect connection with multiple VLANs.
Why it's wrong here
VLANs do not provide physical redundancy.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think a single Direct Connect connection with multiple VLANs provides redundancy, but VLANs only separate traffic logically and do not protect against physical link failure, so multiple physical connections are required for true high availability.
Detailed technical explanation
How to think about this question
For a resilient hybrid network, AWS recommends at least two Direct Connect connections terminating at different locations or through different providers to achieve fault tolerance. BGP with multiple sessions and AS-path prepending allows you to influence route selection and failover behavior, while a VPN backup provides an encrypted, internet-based failover path for when Direct Connect is unavailable, ensuring continuous connectivity.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
