SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company runs a containerized application on Amazon ECS with Fargate launch type. The application experiences intermittent timeouts when calling an external API. The ECS tasks are in a private subnet with a NAT gateway. How can the company improve the reliability of outbound traffic?
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
✓
Deploy a NAT gateway in each Availability Zone and update the route tables.
A NAT Gateway in each AZ provides high availability; without it, a single NAT Gateway failure causes timeouts. Option A is wrong because it reduces security. Option C is wrong because it does not address NAT redundancy. Option D is wrong because it adds complexity without directly fixing NAT issues.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place the tasks in a public subnet with auto-assign public IP.
Why it's wrong here
Reduces security and is not recommended for production.
- ✓
Deploy a NAT gateway in each Availability Zone and update the route tables.
Why this is correct
Eliminates single point of failure for outbound traffic.
- ✗
Increase the NAT gateway's bandwidth by using a larger instance type.
Why it's wrong here
NAT Gateway is managed; no instance type selection.
