Amazon Exam SOA-C02 Topic 1 Question 97 Discussion

Actual exam question for Amazon's SOA-C02 exam

Question #: 97
Topic #: 1

Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the DB cluster to a point in time and then delete the previous DB cluster. This is the most operationally efficient solution that meets the requirements, as it will allow the company to reset the database on a daily basis without having to manually take and restore snapshots. The other solutions (creating a manual snapshot of the DB cluster, enabling the Backtrack feature, or exporting a manual snapshot of the DB cluster to Amazon S3) will require additional steps and resources to reset the database on a daily basis.

A company hosts an application on an Amazon EC2 instance in a single AWS Region. The application requires support for non-HTTP TCP traffic and HTTP traffic.

The company wants to deliver content with low latency by leveraging the AWS network. The company also wants to implement an Auto Scaling group with an

Elastic Load Balancer.

How should a SysOps administrator meet these requirements?

ACreate an Auto Scaling group with an Application Load Balancer (ALB). Add an Amazon CloudFront distribution with the ALB as the origin.

BCreate an Auto Scaling group with an Application Load Balancer (ALB). Add an accelerator with AWS Global Accelerator with the ALB as an endpoint.

CCreate an Auto Scaling group with a Network Load Balancer (NLB). Add an Amazon CloudFront distribution with the NLB as the origin.

DCreate an Auto Scaling group with a Network Load Balancer (NLB). Add an accelerator with AWS Global Accelerator with the NLB as an endpoint.

Show Suggested Answer

Suggested Answer: D

AWS Global Accelerator and Amazon CloudFront are separate services that use the AWS global network and its edge locations around the world. CloudFront improves performance for both cacheable content (such as images and videos) and dynamic content (such as API acceleration and dynamic site delivery). Global Accelerator improves performance for a wide range of applications over TCP or UDP by proxying packets at the edge to applications running in one or more AWS Regions. Global Accelerator is a good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or Voice over IP, as well as for HTTP use cases that specifically require static IP addresses or deterministic, fast regional failover. Both services integrate with AWS Shield for DDoS protection.

Creating an EventBridge rule to automate the daily database reset is a clever solution. As long as the Lambda function is bulletproof, this could be a real time-saver. Although, I do wonder if the database will start to develop a mind of its own after all those daily resets...

D: Hopefully the daily database resets won't cause any unexpected issues in the long run.

I'm going with Option D. Mixing an NLB and AWS Global Accelerator should give you the best of both worlds - reliable TCP traffic handling and global content delivery. Just make sure the Lambda function doesn't accidentally delete the production database instead of the test one.

Agreed, that combination sounds like the best solution for meeting the company's requirements.

I think Option D is the way to go. NLB for TCP traffic and Global Accelerator for low latency content delivery.

Option B looks good. Combining the power of an ALB and AWS Global Accelerator is a smart move to deliver low-latency content. Just don't forget to set a reminder to check the logs every morning for any unexpected database mishaps.

I think Micaela's answer makes sense too, as using a Network Load Balancer with Global Accelerator can also help improve performance.

But using an ALB with CloudFront will help deliver content with low latency, which is a requirement in the question.

A daily database reset? Sounds like a party! I hope the Lambda function doesn't have any bugs, or we might end up with a database that's more like a cryptic treasure map.
