• A.Use the Scan API and a filter expression to match on the key.
• B.Use the GetItem API and a PartiQL statement to match on the key.
• C.Use the ExecuteStatement API and a filter expression to match on the key.

A developer is building an application on AWS. The application has an Amazon API Gateway API that sends requests to an AWS Lambda function. The API is experiencing increased latency because the Lambda function has limited available CPU to fulfill the requests.
Before the developer deploys the API into production, the developer must configure the Lambda function to have more CPU.
Which solution will meet this requirement?

• A.Increase the virtual CPU (vCPU) cores quota of the Lambda function.
• B.Increase the ephemeral storage size of the Lambda function.
• C.Increase the amount of memory that is allocated to the Lambda function.
• D.Increase the timeout value of the Lambda function.

A company is using an AWS Lambda function to process records from an Amazon Kinesis data stream. The company recently observed slow processing of the records. A developer notices that the iterator age metric for the function is increasing and that the Lambda run duration is constantly above normal.
Which actions should the developer take to increase the processing speed? (Choose two.)

• A.Increase the number of shards of the Kinesis data stream.
• B.Decrease the timeout of the Lambda function.
• C.Increase the memory that is allocated to the Lambda function.
• D.Decrease the number of shards of the Kinesis data stream.
• E.Increase the timeout of the Lambda function.

A company is building a serverless application that uses AWS Lambda functions. The company needs to create a set of test events to test Lambda functions in a development environment. The test events will be created once and then will be used by all the developers in an 1AM developer group. The test events must be editable by any of the 1AM users in the 1AM developer group.
Which solution will meet these requirements?

• A.Create and store the test events in Amazon DynamoDB. Allow access to DynamoDB by using 1AM roles.
• B.Create the test events. Configure the event sharing settings to make the test events private.
• C.Create the test events. Configure the event sharing settings to make the test events shareable.
• D.Create and store the test events in Amazon S3 as JSON objects. Allow S3 bucket access to all 1AM users.

A developer is building an application that uses AWS API Gateway APIs. AWS Lambda function, and AWS Dynamic DB tables. The developer uses the AWS Serverless Application Model (AWS SAM) to build and run serverless applications on AWS. Each time the developer pushes of changes for only to the Lambda functions, all the artifacts in the application are rebuilt.
The developer wants to implement AWS SAM Accelerate by running a command to only redeploy the Lambda functions that have changed.
Which command will meet these requirements?

• A.sam deploy -force-upload
• B.sam deploy -no-execute-changeset
• C.sam package
• D.sam sync -watch
