Amazon (SAP-C01) Exam Questions And Answers page 36
A media company is hosting a high-traffic news website on AWS. The website s front end is based solely on HTML and JavaScript. The company loads all dynamic content by using dynamic asynchronous JavaScript requests to a dedicated backend infrastructure.
The front end runs on four Amazon EC2 instances as web servers. The dynamic backend runs in containers on an Amazon Elastic Container Service (Amazon ECS) cluster that uses an Auto Scaling group of EC2 instances. The ECS tasks are behind an Application Load Balancer (ALB).
Which solutions should a solutions architect recommend to optimize costs? (Choose two.)

Implementing cost control strategies
A media company is serving video files stored in Amazon S3 using Amazon CloudFront. The development team needs access to the logs to diagnose faults and perform service monitoring. The log files from CloudFront may contain sensitive information about users.
The company uses a log processing service to remove sensitive information before making the logs available to the development team. The company has the following requirements for the unprocessed logs:
• The logs must be encrypted at rest and must be accessible by the log processing service only.
• Only the data protection team can control access to the unprocessed log files.
• AWS CloudFormation templates must be stored in AWS CodeCommit.
• AWS CodePipeline must be triggered on commit to perform updates made to CloudFormation templates.
• CloudFront is already writing the unprocessed logs to an Amazon S3 bucket, and the log processing service is operating against this S3 bucket.
Which combination of steps should a solutions architect take to meet the company s requirements? (Choose two.)

How Can We Improve Lambda Performance and DynamoDB Reliability?
Multiple Choice
A media storage application uploads user photos to Amazon S3 for processing. End users are reporting that some uploaded photos are not being processed properly. The Application Developers trace the logs and find that AWS Lambda is experiencing execution issues when thousands of users are on the system simultaneously. Issues are caused by:
• Limits around concurrent executions.
• The performance of Amazon DynamoDB when saving data.
Which actions can be taken to increase the performance and reliability of the application? (Choose two.)

A medical company is running an application in the AWS Cloud. The application simulates the effect of medical drugs in development.
The application consists of two parts: configuration and simulation. The configuration part runs in AWS Fargate containers in an Amazon Elastic Container Service (Amazon ECS) cluster. The simulation part runs on large, compute optimized Amazon EC2 instances. Simulations can restart if they are interrupted.
The configuration part runs 24 hours a day with a steady load. The simulation part runs only for a few hours each night with a variable load. The company stores simulation results in Amazon S3, and researchers use the results for 30 days. The company must store simulations for 10 years and must be able to retrieve the simulations within 5 hours.
Which solution meets these requirements MOST cost-effectively?

A mobile app has become very popular, and usage has gone from a few hundred to millions of users. Users capture and upload images of activities within a city, and provide ratings and recommendations. Data access patterns are unpredictable. The current application is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB). The application is experiencing slowdowns and costs are growing rapidly.

A mobile gaming application publishes data continuously to Amazon Kinesis Data Streams. An AWS Lambda function processes records from the data stream and writes to an Amazon DynamoDB table. The DynamoDB table has an auto scaling policy enabled with the target utilization set to 70%.
For several minutes at the start and end of each day, there is a spike in traffic that often exceeds five times the normal load. The company notices the GetRecords.IteratorAgeMilliseconds metric of the Kinesis data stream temporarily spikes to over a minute for several minutes. The AWS Lambda function writes ProvisionedThroughputExceededException messages to Amazon CloudWatch Logs during these times, and some records are redirected to the dead letter queue. No exceptions are thrown by the Kinesis producer on the gaming application.
What change should the company make to resolve this issue?

A multimedia company needs to deliver its video-on-demand (VOD) content to its subscribers in a cost-effective way. The video files range in size from 1-15 GB and are typically viewed frequently for the first 6 months after creation, and then access decreases considerably. The company requires all video files to remain immediately available for subscribers. There are now roughly 30,000 files, and the company anticipates doubling that number over time.
