Question 1

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 : Create a schedule group in Amazon EventBridge Scheduler to invoke the Lambda function.

B : Configure provisioned concurrency for the Lambda function to have the necessary number of execution environments.

C : Use the SLATEST version of the Lambda function.

D : Configure reserved concurrency for the Lambda function to have the necessary number of execution environments.

E : Deploy changes, and publish a new version of the Lambda function.

Answer: B,D

Question 2

A developer is preparing the resources for creating a multicontainer Docker environment on AWS Elastic Beanstalk. How can the developer define the Docker containers?

A : Create a buildspec.yml file and save it at the root of the source directory

B : Define the containers in the Dockerrun.aws.json file in YAML format and save at the root of the source directory

C : Define the containers in the Dockerrun.aws.json file in JSON format and save at the root of the source directory

D : Create a Docker.config file and save it in the .ebextensions folder at the root of the source directory

Answer: C

B : Install the CloudWatch agent on the on-premises servers and EC2 instances

C : Use CloudWatch for monitoring EC2 instances and custom AWS CLI scripts using the put-metric-data API

D : Install the CloudWatch agent on the EC2 instances and use a cron job on the on-premises servers

Answer: B

Question 5
