- A
A route in the on-premises router for the VPC CIDR (10.0.0.0/16) pointing to the AWS Direct Connect router.
Why wrong: This is needed but the question asks for configurations in AWS side, not on-premises.
- B
A route in the VPC route table for 0.0.0.0/0 pointing to the internet gateway.
Required for VPC internet access.
- C
A route in the VPC route table for 0.0.0.0/0 pointing to the virtual private gateway.
Why wrong: That would route internet traffic through Direct Connect, not desired.
- D
A route in the VPC route table for the on-premises CIDR (192.168.0.0/16) pointing to the internet gateway.
Why wrong: Wrong, should point to VGW.
- E
A route in the VPC route table for the on-premises CIDR (192.168.0.0/16) pointing to the virtual private gateway.
Required to route traffic from VPC to on-premises.
Configuring Internet Access for a VPC Connected via Direct Connect
This ANS-C01 practice question tests your understanding of network implementation. 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 using AWS Direct Connect with a private VIF to connect its on-premises network to a VPC. The VPC has a CIDR 10.0.0.0/16. The on-premises network uses 192.168.0.0/16. The company wants to enable communication between on-premises and the VPC, and also allow the VPC to access the internet via an internet gateway. Which TWO of the following configurations are necessary?
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
A route in the VPC route table for 0.0.0.0/0 pointing to the internet gateway.
Option B is correct because an internet gateway (IGW) provides internet access for a VPC, and the VPC's main route table must include a default route (0.0.0.0/0) pointing to the IGW for outbound internet traffic. This allows instances in the VPC to reach the internet, which is a stated requirement. Without this route, traffic destined for the internet would have no path.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The ANS-C01 exam often tests the misconception that a default route (0.0.0.0/0) should point to the virtual private gateway when using Direct Connect, but the correct configuration for internet access is to point it to the internet gateway, while the on-premises CIDR route points to the VGW.
Detailed technical explanation
How to think about this question
A private VIF on Direct Connect uses a virtual private gateway (VGW) attached to the VPC to enable private IP communication between on-premises and the VPC. The VPC route table must have a route for the on-premises CIDR (192.168.0.0/16) pointing to the VGW so that traffic from the VPC to on-premises is forwarded over the Direct Connect link. Additionally, the VPC must have a route for 0.0.0.0/0 pointing to the internet gateway for outbound internet access; note that the VPC's main route table can have both routes, and the most specific route (the on-premises CIDR) will take precedence for that 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
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
