This ANS-C01 practice question tests your understanding of network implementation. 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.
Refer to the exhibit. A subnet is created in VPC vpc-abcde but no explicit route table association is set. What is the default route for internet-bound traffic from this subnet?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Traffic goes through the NAT Gateway nat-67890.
When a subnet is created in a VPC without an explicit route table association, it is implicitly associated with the VPC's main route table. The main route table in this scenario includes a default route (0.0.0.0/0) pointing to NAT Gateway nat-67890, so internet-bound traffic from this subnet is directed through the NAT Gateway. This allows instances in private subnets to initiate outbound internet connections while preventing inbound traffic from the internet.
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.
✗
Traffic is dropped because no explicit association is set.
Common exam trap: answer the scenario, not the keyword
The ANS-C01 exam often tests the misconception that a subnet without an explicit route table association has no routing, when in fact it inherits the VPC's main route table, which may include a default route to a NAT Gateway or Internet Gateway.
Detailed technical explanation
How to think about this question
The main route table in a VPC is created by default and controls routing for subnets without explicit associations. The 0.0.0.0/0 route to a NATGateway enables outbound IPv4 traffic from private subnets, with the NAT Gateway translating private IPs to the Elastic IP of the NAT Gateway. This design is common in multi-tier architectures where web servers in public subnets use an Internet Gateway, while application or database servers in private subnets use a NAT Gateway for updates or API calls.

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.
