- A
Use AWS Transit Gateway to connect multiple VPCs to on-premises via a single VPN.
Why wrong: Transit Gateway is a hub for VPCs, not the primary connectivity solution.
- B
Use a single AWS Direct Connect connection with a backup VPN over the internet.
Why wrong: Backup VPN is lower bandwidth and may not meet throughput requirements.
- C
Set up multiple AWS Site-to-Site VPN connections from the data center to the VPC.
Why wrong: VPN throughput is limited and less consistent than Direct Connect.
- D
Order two AWS Direct Connect connections from different providers and configure them in a LAG.
Multiple Direct Connect connections provide high availability and 10 Gbps throughput.

SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 cloud architecture that requires low-latency connectivity between on-premises and AWS. The company has multiple branch offices connecting to a central data center. The data center must be connected to AWS with 10 Gbps throughput and high availability. Which solution should the company choose?
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
✓
Order two AWS Direct Connect connections from different providers and configure them in a LAG.
Option D is correct because the requirement for 10 Gbps throughput and high availability mandates using two AWS Direct Connect connections from different providers, configured as a Link Aggregation Group (LAG). LAG aggregates multiple connections into a single logical interface, providing both increased bandwidth and redundancy. A single Direct Connect connection with a backup VPN (Option B) would not meet the 10 Gbps throughput requirement, as VPNs are typically limited to lower bandwidth and introduce latency. Option A and C rely on VPNs, which cannot guarantee 10 Gbps throughput and may suffer from internet-based variability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume a single Direct Connect connection with a VPN backup is sufficient for high availability, but the VPN backup cannot match the 10 Gbps throughput and introduces latency, failing the throughput requirement.
Detailed technical explanation
How to think about this question
AWS Direct Connect LAG uses the Link Aggregation Control Protocol (LACP) to combine multiple physical connections into a single logical interface, allowing for load balancing and redundancy. Each connection in the LAG must terminate on the same AWS Direct Connect endpoint and have the same bandwidth (e.g., two 5 Gbps connections for 10 Gbps total). In a real-world scenario, using two different providers ensures that a single provider outage does not disrupt connectivity, meeting the high availability requirement.
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.
