Full question →mediummultiple choiceObjective-mapped
A company stores critical data in an Amazon S3 bucket in the us-west-2 Region. The SysOps administrator needs to ensure that all objects are automatically replicated to another AWS Region for disaster recovery. The Recovery Point Objective (RPO) must be less than 15 minutes, and existing objects must also be replicated. Which S3 feature 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
S3 Cross-Region Replication (CRR) with Replication Time Control (RTC)
CRR replicates objects to a different region. With RTC, it meets the 15-minute RPO and can replicate existing objects when configured.
B
Distractor review
S3 Same-Region Replication (SRR)
SRR replicates within the same region, not across regions, so it does not meet the disaster recovery requirement.
C
Distractor review
S3 Event Notifications with an AWS Lambda function to copy objects to another region
This is custom and does not handle existing objects automatically; also adds operational overhead.
D
Distractor review
S3 Transfer Acceleration
Transfer Acceleration speeds up uploads over long distances but does not provide replication.
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: S3 Cross-Region Replication (CRR) with Replication Time Control (RTC) — S3 Cross-Region Replication (CRR) is designed to automatically replicate objects across AWS Regions. It can be configured to replicate existing objects using the Replication Time Control (RTC) feature or by using S3 Batch Operations. CRR provides near real-time replication, typically within minutes, meeting the RPO of less than 15 minutes. Same-Region Replication (SRR) does not cross regions. Event notifications with Lambda add complexity and do not handle existing objects automatically. Transfer Acceleration is for speeding up uploads, not replication.
