NEW QUESTION # 105
A developer is creating an application that uses an AWS Lambda function to transform and load data from an Amazon S3 bucket. When the developer tests the application, the developer finds that some invocations of the Lambda function are slower than others.
The developer needs to update the Lambda function to have predictable invocation durations that run with low latency. Any initialization activities, such as loading libraries and instantiating clients, must run during allocation time rather than during actual function invocations.
Which combination of steps will meet these requirements? (Select TWO.)

A. Use the SLATEST version of the Lambda function.
B. Deploy changes, and publish a new version of the Lambda function.
C. Create a schedule group in Amazon EventBridge Scheduler to invoke the Lambda function.
D. Configure provisioned concurrency for the Lambda function to have the necessary number of execution environments.
E. Configure reserved concurrency for the Lambda function to have the necessary number of execution environments.

Answer: D,E

A company is using an Amazon API Gateway REST API endpoint as a webhook to publish events from an on-premises source control management (SCM) system to Amazon EventBridge. The company has configured an EventBridge rule to listen for the events and to control application deployment in a central AWS account. The company needs to receive the same events across multiple receiver AWS accounts.

B. Deploy the API Gateway REST API to all the receiver AWS accounts. Create as many SCM webhooks as the number of AWS accounts.
C. Grant permission to the central AWS account for EventBridge to access the receiver AWS accounts.

Explanation
Amazon Cognito user pools support Lambda triggers, which are custom functions that can be executed at various stages of the user pool workflow. A post authentication Lambda trigger can be used to perform custom actions after a user is authenticated, such as sending an email notification. Amazon SES is a cloud-based email sending service that can be used to send transactional or marketing emails. A Lambda function can use the Amazon SES API to send an email to the user's email address after the user logs in successfully.
