- A
Provision two Direct Connect connections to two different Direct Connect locations, each with a private VIF to the same VPC. Use BGP over the VIFs.
This provides physical and logical diversity, achieving high availability with minimal operational overhead.
- B
Provision one Direct Connect connection with a private VIF and a site-to-site VPN connection as a backup.
Why wrong: While this provides backup, it adds operational overhead with VPN, and the primary connection is still a single point of failure.
- C
Provision one Direct Connect connection with two virtual interfaces (VIFs) to the same AWS device.
Why wrong: A single connection and device is a single point of failure.
- D
Provision two Direct Connect connections to the same Direct Connect location, both with private VIFs to the same VPC.
Why wrong: Although two connections, they share the same location which could be a single point of failure (e.g., power outage).
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 network engineer is designing a hybrid network architecture that connects an on-premises data center to AWS using AWS Direct Connect. The company requires high availability and wants to minimize operational overhead. The on-premises network uses BGP to advertise routes to AWS. Which design meets these requirements?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 Direct Connect connections to two different Direct Connect locations, each with a private VIF to the same VPC. Use BGP over the VIFs.
Option A is correct because provisioning two Direct Connect connections to two different Direct Connect locations ensures physical and path diversity, eliminating single points of failure. Using BGP over the private VIFs allows dynamic route advertisement and automatic failover, meeting high availability requirements while minimizing operational overhead through managed BGP sessions.
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.
- ✓
Provision two Direct Connect connections to two different Direct Connect locations, each with a private VIF to the same VPC. Use BGP over the VIFs.
Why this is correct
This provides physical and logical diversity, achieving high availability with minimal operational overhead.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Provision one Direct Connect connection with a private VIF and a site-to-site VPN connection as a backup.
Why it's wrong here
While this provides backup, it adds operational overhead with VPN, and the primary connection is still a single point of failure.
- ✗
Provision one Direct Connect connection with two virtual interfaces (VIFs) to the same AWS device.
Why it's wrong here
A single connection and device is a single point of failure.
- ✗
Provision two Direct Connect connections to the same Direct Connect location, both with private VIFs to the same VPC.
Why it's wrong here
Although two connections, they share the same location which could be a single point of failure (e.g., power outage).
Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that multiple VIFs on a single connection or connections to the same location provide sufficient redundancy, but true high availability requires physical and geographic diversity at the connection level.
Detailed technical explanation
How to think about this question
Under the hood, BGP multipath and AS_PATH prepending can be used to influence traffic flow across the two Direct Connect connections, while AWS Direct Connect Gateway supports transitive routing between VIFs and VPCs. In a real-world scenario, using two different Direct Connect locations (e.g., Equinix NY1 and CoreSite NY2) ensures that a fiber cut or power outage at one facility does not impact the other, achieving an SLA of 99.99% uptime.
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.
