- A
Set a higher local preference on the VPN route to make it preferred over Direct Connect.
Why wrong: The VPN should be a backup, so it should have lower local preference.
- B
Configure the VPN connection with static routes instead of BGP.
Why wrong: Static routes do not provide dynamic failover based on BGP attributes.
- C
Disable route propagation on the VPN connection's route table.
Why wrong: Disabling propagation would remove the VPN routes, preventing failover.
- D
Adjust BGP attributes on the Direct Connect routes to be preferred over the VPN routes.
By making Direct Connect routes more preferred (e.g., higher local preference), the VPN will only be used when Direct Connect is down.
- E
Use a VPN connection that supports dynamic BGP routing.
BGP allows dynamic route advertisement and automatic failover.
Quick Answer
The answer is to use a VPN connection that supports dynamic BGP routing and to adjust BGP attributes so that the Direct Connect routes are preferred over the VPN routes. This works because BGP’s path selection process, specifically local preference, allows you to assign a higher value to Direct Connect routes, making them the primary path, while the VPN routes with a lower local preference serve as the backup. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of BGP failover design for hybrid networks, often appearing as a trap where candidates mistakenly choose static routes or disable route propagation. A common memory tip is to think of local preference as a “tiebreaker” that you set high for your primary link—Direct Connect—so that if both Direct Connect connections fail, BGP automatically falls back to the VPN without manual intervention. Remember: higher local preference wins, so keep your backup VPN’s preference lower.
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 is designing a hybrid network using AWS Direct Connect and a Site-to-Site VPN as a backup. The company has two Direct Connect connections from different providers for redundancy. The company wants to use BGP to automatically fail over to the VPN if both Direct Connect connections fail. Which TWO configurations are required to achieve this?
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
Adjust BGP attributes on the Direct Connect routes to be preferred over the VPN routes.
Option B and Option E are correct. A VPN connection uses BGP to exchange routes, and adjusting BGP attributes (like local preference) can make the VPN route less preferred than Direct Connect routes. Option A is wrong because static routes do not provide dynamic failover. Option C is wrong because the VPN should be a backup, so it should have lower local preference. Option D is wrong because disabling route propagation on the VPN would remove its routes.
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
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.
