Full question →easymultiple choiceObjective-mapped
A SysOps administrator needs to deploy a set of AWS Lambda functions and an Amazon API Gateway API using infrastructure as code. The administrator wants to manage the deployment across multiple environments (dev, test, prod) with consistent resource configurations. Which AWS service should the administrator use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
AWS CloudFormation
AWS CloudFormation is the correct choice because it provides infrastructure as code capabilities, enabling you to define resources in a template and deploy them consistently across environments.
B
Distractor review
AWS CodeDeploy
AWS CodeDeploy is used for automating code deployments to running instances, not for provisioning infrastructure resources like Lambda and API Gateway.
C
Distractor review
AWS Elastic Beanstalk
AWS Elastic Beanstalk is a managed service for web applications and does not natively support managing Lambda functions and API Gateway directly without additional configuration.
D
Distractor review
AWS OpsWorks
AWS OpsWorks uses Chef/Puppet for configuration management, which is not designed for declarative infrastructure as code like CloudFormation.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A company uses Amazon CloudFront to deliver content to a global audience. The origin is an Application Load Balancer in us-east-1. The SysOps administrator wants to reduce costs by minimizing the number of requests that reach the origin server. Which action should the administrator take?
Question 2
A company runs a batch processing application on Amazon EC2 that runs for 2 hours every night. The workload can tolerate interruptions. Which EC2 purchasing option provides the lowest cost for this use case?
Question 3
A SysOps administrator needs to monitor the CPU utilization of an Amazon RDS DB instance and receive an alarm when CPU utilization exceeds 80% for 5 consecutive minutes. Which AWS service should be used to create this alarm?
Question 4
A company runs a critical web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application uses session stickiness (sticky sessions) to maintain user sessions. The SysOps administrator notices that when instances are replaced during a scale-in or failure event, users lose their session data. The administrator needs to preserve session data across instance failures without losing stickiness benefits. What should the administrator do?
Question 5
A company runs a production web application on a single Amazon EC2 instance. The application experiences a predictable and steady workload 24/7. The SysOps administrator wants to minimize compute costs for this instance while ensuring it remains available during the expected workload. Which EC2 purchasing option should the administrator use?
Question 6
A company has a VPC with public and private subnets. The private subnets host application servers that need to make outbound HTTPS connections to the internet. The SysOps administrator must implement a solution that provides outbound internet connectivity while preventing inbound connections from the internet. Additionally, the solution must allow the company to control which domains the application servers can access. Which solution should the administrator implement?
FAQ
Questions learners often ask
What does this SOA-C02 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: AWS CloudFormation — AWS CloudFormation is the correct service for managing infrastructure as code. It allows you to define resources such as Lambda functions and API Gateway APIs in a template and deploy them consistently across multiple environments using stacks and parameters. AWS CodeDeploy is for deploying applications to compute services, not for defining infrastructure. AWS Elastic Beanstalk is a platform as a service for web applications and does not directly manage Lambda and API Gateway natively. AWS OpsWorks is a configuration management service using Chef or Puppet, not suited for declarative infrastructure as code.
