This ANS-C01 practice question tests your understanding of network design. 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 architecture that requires a dedicated, private, and consistent connection between its on-premises data center and AWS. The connection must support multiple VLANs and provide a service-level agreement (SLA) of 99.99% availability. Which AWS service should be used to meet these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Direct Connect
AWS Direct Connect is the correct choice because it provides a dedicated, private, and consistent network connection from an on-premises data center to AWS, bypassing the public internet. It supports multiple VLANs via 802.1Q tagging over a single physical connection, and offers a 99.99% service-level agreement (SLA) when configured with redundant connections at separate Direct Connect locations.
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.
✓
AWS Direct Connect
Why this is correct
Correct; AWS Direct Connect provides a dedicated, private, high-bandwidth connection with support for multiple VLANs and an SLA.
Related concept
Read the scenario before looking for a memorised answer.
✗
AWS Transit Gateway
Why it's wrong here
Incorrect; Transit Gateway is a central hub to interconnect VPCs and on-premises networks, but it is not a connection service itself.
✗
AWS Client VPN
Why it's wrong here
Incorrect; AWS Client VPN is for remote client access, not for connecting data centers.
✗
AWS Site-to-Site VPN
Why it's wrong here
Incorrect; AWS Site-to-Site VPN is not dedicated and does not offer a 99.99% SLA.
Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that AWS Transit Gateway itself provides the dedicated connection, but it is only a logical aggregation point and requires Direct Connect or VPN as the underlying transport to meet the physical connectivity and SLA requirements.
Detailed technical explanation
How to think about this question
Direct Connect uses 802.1Q VLAN tagging to segregate traffic into multiple virtual interfaces (VIFs) over a single physical circuit, enabling separate public and private connectivity. The 99.99% SLA is achieved by requiring two separate connections to two different Direct Connect locations, ensuring redundancy against single points of failure. Under the hood, Direct Connect leverages MPLS-based circuits from AWS partners, providing deterministic performance that bypasses internet congestion.

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.
