Question1: A financial company is building a system to generate monthly, immutable bank account statements for its users Statements are stored in Amazon S3 Users should have immediate access to their monthly statements for up to 2 years Some users access then statements frequently whereas others rarely access their statements. The company's security and compliance policy requires that the statements be retained for at least 7 years What is the MOST cost-effective solution to meet the company's needs?

Question2: A company has a website that enables users to upload videos Company policy states the uploaded videos must be analyzed for restricted content An uploaded video is placed in Amazon S3, and a message is pushed to an Amazon SQS queue with the video's location A backend application pulls this location from Amazon SQS and analyzes the video The video analysis is compute-intensive and occurs sporadically during the day The website scales with demand The video analysis application runs on a fixed number of instances Peak demand occurs during the holidays, so the company must add instances to the application during this time All instances used are currently on-demand Amazon EC2 T2 instances The company wants to reduce the cost of the current solution.
Which of the following solutions is MOST cost-effective?

Question3: A company is using AWS Organizations to manage multiple accounts Due to regulatory requirements the company wants to restrict specific member accounts to certain AWS Regions where they are permitted to deploy resources. The resources in the accounts must be tagged enforced based on a group standard and centrally managed with minimal configuration.
What should a solutions architect do to meet these requirements?

Question4: A Solutions Architect is designing the storage layer for a data warehousing application. The data files are large, but they have statically placed metadata at the beginning of each file that describes the size and placement of the file's index. The data files are read in by a fleet of Amazon EC2 instances that store the index size, index location, and other category information about the data file in a database. That database is used by Amazon EMR to group files together for deeper analysis.
What would be the MOST cost-effective, high availability storage solution for this workflow?

Question5: A company's main intranet page has experienced degraded response times as its user base has increased although there are no reports of users seeing error pages. The application uses Amazon DynamoDB in read-only mode.
Amazon DynamoDB latency metrics for successful requests have been in a steady state even during times when users have reported degradation The Development team has correlated the issue to ProvisionedThrough put Exceeded exceptions in the application logs when doing Scan and read operations The team also identified an access pattern of steady spikes of read activity on a distributed set of individual data items The Chief Technology Officer wants to improve the user experience Which solutions will meet these requirements with the LEAST amount of changes to the application? (Select TWO )

Question6: A company has a serverless application comprised of Amazon CloudFront, Amazon API Gateway, and AWS Lambda functions. The current deployment process of the application code is to create a new version number of the Lambda function and run an AWS CLI script to update. If the new function version has errors, another CLI script reverts by deploying the previous working version of the function. The company would like to decrease the time to deploy new versions of the application logic provided by the Lambda functions, and also reduce the time to detect and revert when errors are identified.
How can this be accomplished?

Question7: A company is migrating a subset of its application APIs from Amazon EC2 instances to run on a serverless infrastructure. The company has set up Amazon API Gateway, AWS Lambda, and Amazon DynamoDB for the new application. The primary responsibility of the Lambda function is to obtain data from a third-party Software as a Service (SaaS) provider. For consistency, the Lambda function is attached to the same virtual private cloud (VPC) as the original EC2 instances.
Test users report an inability to use this newly moved functionality, and the company is receiving 5xx errors from API Gateway. Monitoring reports from the SaaS provider shows that the requests never made it to its systems. The company notices that Amazon CloudWatch Logs are being generated by the Lambda functions. When the same functionality is tested against the EC2 systems, it works as expected.
What is causing the issue?

Question8: 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.IteratorAge Milliseconds metric of the Kinesis data stream temporarily spikes to over a minute for several minutes. The AWS Lambda function writes Provisioned Throughput Exceeded Exception 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?

Question9: The Security team needs to provide a team of interns with an AWS environment so they can build the serverless video transcoding application. The project will use Amazon S3, AWS Lambda, Amazon API Gateway, Amazon Cognito, Amazon DynamoDB, and Amazon Elastic Transcoder.
The interns should be able to create and configure the necessary resources, but they may not have access to create or modify AWS IAM roles. The Solutions Architect creates a policy and attaches it to the interns' group.
How should the Security team configure the environment to ensure that the interns are self-sufficient?

Question10: A photo-sharing and publishing company receives 10,000 to 150,000 images daily. The company receives the images from multiple suppliers and users registered with the service. The company is moving to AWS and wants to enrich the existing metadata by adding data using Amazon Rekognition.

The company uses a NAT gateway to allow these systems to communicate with external vendors over IPv4. Company policy requires systems that communicate with external vendors use a security group that limits access to only approved external vendors. The virtual private cloud (VPC) uses the default network ACL.
The Systems Operator successfully assigns IPv6 addresses to each of the backend systems.

Question65: A company has a standard three-tier architecture using two Availability Zones. During the company's off season, users report that the website is not working. The Solutions Architect finds that no changes have been made to the environment recently, the website is reachable, and it is possible to log in. However, when the Solutions Architect selects the "find a store near you" function, the maps provided on the site by a third-party RESTful API call do not work about 50% of the time after refreshing the page.
