ANS-C01 Network Design Practice Question

This ANS-C01 practice question tests your understanding of network design. 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 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?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "least"

    Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.

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

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 provisioning two AWS Direct Connect connections at two different Direct Connect locations, each with a 10 Gbps port, and connecting each on-premises router to one of them provides both high availability (via geographic and path redundancy) and the required 10 Gbps bandwidth with low latency for real-time data replication. This design eliminates single points of failure and meets the bandwidth requirement without relying on VPNs, which cannot guarantee consistent low latency or 10 Gbps throughput.

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.

  • 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

    Single Direct Connect connection is a single point of failure.

  • 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.

    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

    Read the scenario before looking for a memorised answer.

  • 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 it's wrong here

    VPN throughput is limited and may not meet 10 Gbps requirement.

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 redundant routers on-premises is sufficient for high availability, but they overlook that the Direct Connect connection itself (including the physical fiber and the AWS Direct Connect location) is a single point of failure, requiring two separate connections at different locations to meet true high availability.

Detailed technical explanation

How to think about this question

AWS Direct Connect provides dedicated, private network connections from on-premises to AWS, bypassing the internet to deliver consistent low latency and high bandwidth (up to 100 Gbps per connection). By using two separate Direct Connect locations (e.g., different AWS Direct Connect Points of Presence), the design achieves fault isolation and can leverage BGP multipath or ECMP for load balancing across the two 10 Gbps links, effectively providing up to 20 Gbps aggregate bandwidth while maintaining sub-millisecond latency for real-time replication traffic.

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.
