Master AWS Certifications with Confidence

Which cloud concept is demonstrated by using AWS Compute Optimizer?

Which AWS Cloud characteristic allows automatic adjustment of compute resources to match varying application traffic?

A global sports streaming platform uses Real Time Messaging Protocol (RTMP) to receive live feeds from commentators located worldwide. The platform requires a solution that ensures commentators can transmit high-quality streams with minimal latency. The architecture must prioritize accelerated and reliable TCP connections to the central streaming system. Which AWS service should be used to fulfill these requirements?

A company is deploying a high-performance database on multiple Amazon EC2 Nitro-based instances within the same Availability Zone. The database requires block storage that can be attached to multiple instances simultaneously for failover support. The solution must ensure the highest durability and consistent low-latency performance for mission-critical workloads. Which option meets these requirements?

A solutions architect needs to migrate an on-premises video rendering application to AWS. Users upload video files through a web interface, which are stored on a shared file system. The rendering process, which can take up to 2 hours per file, is triggered via a message queue. The workload fluctuates significantly, with high demand during business hours and low demand otherwise. What is the MOST cost-effective migration strategy?

A company hosts its web application using Amazon ECS tasks on AWS Fargate, which are fronted by an Application Load Balancer (ALB). The service uses ECS Service Auto Scaling based on CPU utilization to handle traffic fluctuations.

Recently, the application became unresponsive due to a surge in traffic. Investigation revealed that the traffic spike was caused by numerous SQL injection attacks, which also triggered the service to scale out to its maximum limit.

The solutions architect must design a solution to prevent SQL injection attacks from reaching the ECS tasks. The solution must ensure legitimate traffic is unaffected and maintain operational efficiency.

Which solution meets these requirements?

A developer needs to design a serverless application that processes data every week at a specific time. The company has no existing AWS infrastructure but wants to implement this solution with minimal operational overhead. Which approach provides the MOST operationally efficient implementation?

A development team uses AWS CloudFormation to manage a web application that includes an Amazon S3 bucket for critical data storage. During a recent stack update, a developer accidentally caused the S3 bucket to be deleted and recreated, resulting in data loss. The team needs to prevent such accidental deletions in the future. Which solutions will meet these requirements? (Choose two.)
