SAA-C03 Exam
The AWS SAA-C03 and DVA-C02 exams are both certification exams offered by Amazon Web Services, but they focus on different roles and skill sets. Here are the key differences:
A company has deployed a multi-tier web application to support a website. The architecture includes an Application Load Balancer (ALB) in public subnets, two Amazon Elastic Container Service (Amazon ECS) tasks in the public subnets, and a PostgreSQL cluster that runs on Amazon EC2 instances in private subnets.
The EC2 instances that host the PostgreSQL database run shell scripts that need to access an external API to retrieve product information. A solutions architect must design a solution to allow the EC2 instances to securely communicate with the external API without increasing operational overhead.
Which solution will meet these requirements?
A solutions architect needs to implement a solution that can handle up to 5,000 messages per second. The solution must publish messages as events to multiple consumers. The messages are upto 500 KB in size. The message consumers need to have the ability to use multiple programming languages to consume the messages with minimal latency. The solution must retain published messages for more than 3 months. The solution must enforce strict ordering of the messages.
Which solution will meet these requirements?
A company needs to accommodate traffic for a web application that the company hosts on AWS, especially during peak usage hours.
The application uses Amazon EC2 instances as web servers, an Amazon RDS DB instance for database operations, and an Amazon S3 bucket to store transaction documents. The application struggles to scale effectively and experiences performance issues.
The company wants to improve the scalability of the application and prevent future performance issues. The company also wants to improve global access speeds to the transaction documents for the company ' s global users.
