Quick Answer
The correct answer is two VPN tunnels in active/active mode with BGP. This configuration ensures both tunnels are always forwarding traffic, providing true high availability and meeting the requirement for always-on connectivity, whereas an active/passive setup leaves one tunnel idle. By using BGP for dynamic routing, the tunnels can automatically fail over and load-balance traffic, which is essential for a resilient hybrid network. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how active/active VPN tunnels differ from active/passive, and a common trap is assuming static routes suffice—BGP is required to advertise the same prefixes over both tunnels and enable simultaneous use. Remember the mnemonic “Two Tunnels, BGP Both” to recall that active/active demands dynamic routing for full utilization.
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 implementing a hybrid network using AWS Site-to-Site VPN. The on-premises firewall requires that the VPN tunnels use IKEv2 with pre-shared keys and that the tunnels are always active. Which VPN configuration should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
Two VPN tunnels in active/passive mode
Why wrong: Active/passive means one tunnel is not always active.
Two VPN tunnels with static routing
Why wrong: Static routing is less flexible than dynamic routing for failover.
One VPN tunnel with static routing
Why wrong: A single tunnel lacks redundancy.
Two VPN tunnels in active/active mode with BGP
Active/active tunnels with BGP provide high availability and always-on connectivity.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Two VPN tunnels in active/active mode with BGP
Option C is correct because two tunnels in active/active mode provide high availability and always-on connectivity. Option A is wrong because one tunnel is not redundant. Option B is wrong because active/passive means one tunnel is standby. Option D is wrong because dynamic routing with BGP is typically used, not static routes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Two VPN tunnels in active/passive mode
Why it's wrong here
Active/passive means one tunnel is not always active.
Two VPN tunnels with static routing
Why it's wrong here
Static routing is less flexible than dynamic routing for failover.
One VPN tunnel with static routing
Why it's wrong here
A single tunnel lacks redundancy.
Two VPN tunnels in active/active mode with BGP
Why this is correct
Active/active tunnels with BGP provide high availability and always-on connectivity.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
