A developer is creating as AWS lambda function that generates a new file each time it runs. Each new file must be checked into an AWS CodeCommit repository hosted in the same AWS account.
How should the developer accomplish this?

• A.After the new file is created in Lambda, use cURL to invoke the CodeCommit API. Send the file to the repository.
• B.When the Lambda function starts, use the Git CLI to Clone the repository. Check the new file into the cloned repository and push the change.
• C.Upload the new file to an Amazon S3 bucket. Create an AWS step Function to accept S3 events. In the step Function, add the new file to the repository.
• D.Use an AWS SDK to instantiate a CodeCommit Client. Invoke the put _ file method to add the file to the repository.

A Developer is building a three-tier web application that should be able to handle a minimum of 5000 requests per minute. Requirements state that the web tier should be completely stateless while the application maintains session state for the users.
How can session data be externalized, keeping latency at the LOWEST possible value?

• A.Create an Amazon RDS instance, then implement session handling at the application level to leverage a database inside the RDS database instance for session data storage
• B.Implement a shared file system solution across the underlying Amazon EC2 instances, then implement session handling at the application level to leverage the shared file system for session data storage
• C.Create an Amazon ElastiCache Memcached cluster, then implement session handling at the application level to leverage the cluster for session data storage
• D.Create an Amazon DynamoDB table, then implement session handling at the application level to leverage the table for session data storage

A company maintains a REST service using Amazon API Gateway and the API Gateway native API key validation. The company recently launched a new registration page, which allows users to sign up for the service. The registration page creates a new API key using CreateApiKey and sends the new key to the user.
When the user attempts to call the API using this key, the user receives a 403 Forbidden error. Existing users are unaffected and can still call the API.
What code updates will grant these new users access to the API?

• A.The createDeployment method must be called so the API can be redeployed to include the newly created API key.
• B.The updateAuthorizer method must be called to update the API's authorizer to include the newly created API key.
• C.The importApiKeys method must be called to import all newly created API keys into the current stage of the API.
• D.The createUsagePlanKey method must be called to associate the newly created API key with the correct usage plan.

A Developer is investigating an issue whereby certain requests are passing through an Amazon API Gateway endpoint /MyAPI, but the requests do not reach the AWS Lambda function backing /MyAPI. The Developer found that a second Lambda function sometimes runs at maximum concurrency allowed for the given AWS account.
How can the Developer address this issue?

• A.Manually reduce the concurrent execution limit at the account level
• B.Add another API Gateway stage for /MyAPI, and shard the requests
• C.Configure the second Lambda function's concurrency execution limit
• D.Reduce the throttling limits in the API Gateway /MyAPI endpoint
