Full question →easymultiple choiceObjective-mapped
A company runs a critical web application on a single Amazon EC2 instance with a 100 GiB gp2 EBS volume. The SysOps administrator needs to ensure data durability by taking automated snapshots of the root volume every hour. The snapshots should be retained for 7 days. Which AWS service can be used to automate this task with minimal configuration?
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
Amazon Data Lifecycle Manager (DLM)
DLM provides built-in automation for creating and retaining EBS snapshots according to a schedule, making it the ideal choice.
B
Distractor review
AWS Backup
AWS Backup can create EBS snapshots as part of a broader backup plan, but it is more complex than DLM for this specific single-volume scenario.
C
Distractor review
Amazon CloudWatch Events
CloudWatch Events can invoke a Lambda function to trigger snapshots, but requires custom code and does not natively manage retention.
D
Distractor review
AWS Systems Manager
Systems Manager automation can run scripts that create snapshots, but it is not a dedicated snapshot lifecycle management service.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Amazon Data Lifecycle Manager (DLM) — Amazon Data Lifecycle Manager (DLM) is the service specifically designed to automate the creation, retention, and deletion of EBS snapshots and EBS-backed AMIs. It allows you to create a policy to take snapshots at specified intervals and retain them for a defined period. AWS Backup is a broader backup service that can also handle EBS snapshots, but DLM is simpler and more targeted for this use case. CloudWatch Events and Systems Manager are not directly suited for snapshot lifecycle automation.
