A company operates a media streaming platform that delivers on-demand video content to users from around the world. User requests flow through an Amazon CloudFront distribution, an Amazon API Gateway REST API, AWS Lambda functions, and Amazon DynamoDB tables.
Some users have reported intermittent buffering issues and delays when users try to start a video stream. The company needs to investigate the issues to discover the underlying cause.
Which solution will meet this requirement?

• A.Use AWS Config to review details of any recent configuration changes to AWS resources in the application that could result in increased latency for users.
• B.Use AWS CloudTrail to track AWS resources in all AWS Regions. Stream CloudTrail data to an Amazon CloudWatch Logs log group. Enable CloudTrail Insights. Set up Amazon SN5 notifications if unusual API activity is detected.
• C.Enable logging in API Gateway. Ensure that each Lambda function is configured to send logs to Amazon CloudWatch. Use CloudWatch Logs Insights to query the log data.
• D.Enable AWS X-Ray tracing for the REST API, Lambda functions, and DynamoDB tables. Analyze the service map to identify any performance bottlenecks or errors.

A company caches session information for a web application in an Amazon DynamoDB table.
The company wants an automated way to delete old items from the table.
What is the simplest way to do this?

• A.Add an attribute with the expiration time; enable the Time To Live feature based on that attribute.
• B.Each day, create a new table to hold session data; delete the previous day's table.
• C.Add an attribute with the expiration time; name the attribute ItemExpiration.
• D.Write a script that deletes old records; schedule the script as a cron job on an Amazon EC2 instance.

A developer runs an application that displays scores for sports games on Amazon EC2 instances.
The application uses a Redis client to retrieve the scores from an Amazon ElastiCache (Redis OSS) cluster. The developer observes increased latency during operations on the cache because of connection failures to the cluster. The developer needs to resolve the latency issues.
Which solution will meet this requirement?

• A.Configure the Redis client to use an exponential backoff retry strategy to establish cache connections.
• B.Store the scores in the application's memory. Perform bulk set operations on the scores that are stored in memory.
• C.Configure the Redis client in the application to persist connections to the cluster by implementing a connection pool.
• D.Deploy more nodes in the ElastiCache cluster. Update the Redis client to discover the new nodes.

A company is building a content authoring application. The application has multiple user groups, such as content creator, reviewer, approver, and administrator. The company needs to assign users fine-grained permissions for specific parts of the application. The company needs a solution to configure, maintain, and analyze user permissions. The company wants a solution that can be easily adapted to work with newer applications in the future. The company must use a third-party OpenID Connect (OIDC) identity provider (IdP) to authenticate users.
Which solution will best meet these requirements?

• A.Configure an Amazon Cognito identity pool for the application. Use the identity pool identities within the application to manage user permissions.
• B.Configure the application to check user permissions upon request. Configure the application logic to manage user permissions.
• C.Use Amazon Verified Permissions to set up user permissions. Integrate Verified Permissions with a third-party IdP. Configure the application to request authorization decisions from Verified Permissions.
• D.Set up an IAM role for each user group. Assign users appropriate IAM roles. Configure the application to determine appropriate permissions for each user based on the user's IAM role.

A development team maintains a web application by using a single AWS CloudFormation template. The template defines web servers and an Amazon RDS database. The team uses the Cloud Formation template to deploy the Cloud Formation stack to different environments.
During a recent application deployment, a developer caused the primary development database to be dropped and recreated. The result of this incident was a loss of data. The team needs to avoid accidental database deletion in the future.
Which solutions will meet these requirements? (Choose two.)

• A.Add a CloudFormation Deletion Policy attribute with the Retain value to the database resource.
• B.Update the CloudFormation stack policy to prevent updates to the database.
• C.Modify the database to use a Multi-AZ deployment.
• D.Create a CloudFormation stack set for the web application and database deployments.
• E.Add a Cloud Formation DeletionPolicy attribute with the Retain value to the stack.
