- A
Use AWS Direct Connect Gateway to aggregate multiple VPN connections to achieve higher bandwidth.
Why wrong: Direct Connect Gateway does not provide the physical connection; it is used to connect multiple VPCs to a Direct Connect.
- B
Provision a single AWS Direct Connect connection with a 10 Gbps port and connect both on-premises routers to it via a single interface.
Why wrong: Single Direct Connect connection is a single point of failure.
- C
Provision two AWS Direct Connect connections at two different Direct Connect locations, each with a 10 Gbps port, and connect each on-premises router to one of them.
Provides high availability and meets bandwidth/latency requirements.
- D
Set up two AWS Site-to-Site VPN tunnels from each on-premises router to two different AWS VPN endpoints in the same region.
Why wrong: VPN throughput is limited and may not meet 10 Gbps requirement.
Quick Answer
The answer is to provision two AWS Direct Connect connections at two different Direct Connect locations, each with a 10 Gbps port, and connect each on-premises router to one of them. This design meets the 10 Gbps low-latency hybrid connectivity requirement because AWS Direct Connect provides a dedicated, private network path that bypasses the public internet, ensuring consistent high bandwidth and low latency for real-time data replication. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this question tests your understanding of high-availability hybrid architectures, specifically the need for geographic and device-level redundancy to avoid a single point of failure. A common trap is choosing a single Direct Connect connection or relying on AWS VPN, which is capped at roughly 1.25 Gbps per tunnel and cannot achieve 10 Gbps. Remember the memory tip: “Two sites, two ports, two routers” — for any scenario demanding 10 Gbps and high availability, always think dual Direct Connect locations with redundant on-premises termination.
ANS-C01 Network Design Practice Question
This ANS-C01 practice question tests your understanding of network design. 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.
A company is migrating its on-premises data center to AWS. The network team needs to design a hybrid connectivity solution that provides high availability with a bandwidth of at least 10 Gbps and low latency for real-time data replication. The company has two redundant on-premises routers connected to two separate internet service providers (ISPs). Which combination of AWS services should the company use to meet these requirements?

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
Provision two AWS Direct Connect connections at two different Direct Connect locations, each with a 10 Gbps port, and connect each on-premises router to one of them.
Option C is correct because AWS Direct Connect provides dedicated, low-latency, high-bandwidth connections. Using two Direct Connect locations with redundant connections ensures high availability. Option A is wrong because AWS VPN is limited to ~1.25 Gbps per tunnel and may not meet the 10 Gbps requirement. Option B is wrong because a single Direct Connect connection is a single point of failure. Option D is wrong because Direct Connect Gateway does not provide the connection itself.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Direct Connect Gateway to aggregate multiple VPN connections to achieve higher bandwidth.
Why it's wrong here
Direct Connect Gateway does not provide the physical connection; it is used to connect multiple VPCs to a Direct Connect.
- ✗
Provision a single AWS Direct Connect connection with a 10 Gbps port and connect both on-premises routers to it via a single interface.
Why it's wrong here

Why this is correct
Provides high availability and meets bandwidth/latency requirements.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.

Why it's wrong here
VPN throughput is limited and may not meet 10 Gbps requirement.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
