Full question →easymultiple choiceObjective-mapped
A company has multiple on-premises branch offices, each with a site-to-site VPN connection to a single VPC in AWS. The SysOps administrator needs to enable communication between the branch offices using the AWS cloud as a hub. Which configuration should be implemented to achieve this with the least operational overhead?
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
Distractor review
Configure static routes in the VPC route table pointing to each VPN connection.
Static routes require manual updates for each new branch and do not automatically propagate routes between VPN connections, making this approach less scalable and more operationally heavy.
B
Best answer
Use dynamic routing (BGP) on all VPN connections and enable route propagation on the virtual private gateway (VGW).
Dynamic routing with BGP and route propagation on the VGW allows the VPC to automatically exchange routes between VPN connections, enabling branch-to-branch communication without manual intervention.
C
Distractor review
Create a separate Transit VPC with EC2-based VPN appliances to route traffic between branch offices.
This approach adds unnecessary complexity and cost. The VPN CloudHub model using a single VPC with dynamic routing is simpler and achieves the same goal.
D
Distractor review
Place all branch offices in the same IPsec tunnel by configuring identical pre-shared keys.
IPsec tunnels are point-to-point connections; placing multiple branches in the same tunnel is not possible and would cause routing conflicts.
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: Use dynamic routing (BGP) on all VPN connections and enable route propagation on the virtual private gateway (VGW). — To enable communication between branch offices connected via site-to-site VPN to the same VPC, the VPC must be configured to act as a hub. By using dynamic routing (BGP) and enabling route propagation on the virtual private gateway, the VPC can exchange routes between the VPN connections. This allows each branch office to learn the routes of the other branch offices through the AWS cloud, effectively creating a VPN CloudHub. Static routing would require manual route management and does not scale easily.
