Question #3
A company is using AWS Database Migration Service (AWS DMS) to replicate data from a source database in a data center to a target Amazon Aurora PostgreSQL database. The company has created a DMS replication task with change data capture (CDC). The replication instance sometimes gets interrupted and affects critical functionality. The company must improve the replication instance's resiliency and receive notifications about interruptions. Which solution will meet these requirements with the LEAST operational overhead?
A. opy data from the source database to Amazon S3 by using AWS DataSync
B. reate Amazon CloudWatch alarms to monitor DMS replication task metrics and host metrics
C. reate Amazon CloudWatch alarms to monitor DMS replication task metrics and host metrics
D. odify the DMS replication instance by turning on Multi-AZ support

Question #4
A company is using an Amazon API Gateway API and an AWS Lambda function to host a microservice. The microservice accesses pricing data in an Amazon DynamoDB table for the company's online store. Interest in the online store has increased. As a result, latency issues and throttling on the DynamoDB table are occurring when a specific query runs. Some internal services access the DynamoDB table directly. No caching is enabled for the current solution. A DevOps engineer notices that repeat requests to the API are taking the same amount of time as unique requests. The DevOps engineer must reduce the latency for the repeat requests to the API and must reduce the throttling on the DynamoDB table. Which solution will meet these requirements?
A. nable caching for API Gateway stages
B. nable caching for API Gateway stages
C. se provisioned concurrency for the Lambda function
D. se provisioned concurrency for the Lambda function

Correct Answer: B
Question #5
A company needs to identify AWS Lambda functions that are running end-of-life (EOL) language runtimes in an AWS account. The account is part of an organization in AWS Organizations and has only the AWS Basic Support plan. A DevOps engineer must create a monitoring solution that notifies the company about any Lambda functions that are running EOL runtimes. The company already has created an Amazon Simple Notification Service (Amazon SNS) topic. The company also has configured AWS Config for the account. What should the DevOps engineer do to meet the requirements?
A. reate an AWS Config custom rule that is associated with a Lambda function
B. reate an Amazon EventBridge rule that has an AWS Health event pattern
C. onfigure the LAMBDA FUNCTION SETTINGS CHECK managed rule in AWS Config
D. onfigure AWS Trusted Advisor for the AWS account

Correct Answer: C
Question #6
A company has an AWS account that contains an EC2 Image Builder pipeline that the company uses to create and test Amazon Linux golden images. In the same AWS account, the company has created a new AWS CodePipeline pipeline that packages the code for a custom Amazon EC2 agent. The final step in the CodePipeline pipeline publishes the packaged agent to an AWS CodeArtifact repository. A DevOps engineer needs to update the Image Builder pipeline to build a new Amazon Linux golden image whenever a new version of the custom EC2 agent is created. Which solution will meet this requirement in the MOST operationally efficient manner?
A. reate an Amazon EventBridge rule to start a new Image Builder pipeline when the agent package is published to the CodeArtifact repository
B. reate an Amazon EventBridge rule to start a new Image Builder pipeline when the agent package is published to the CodeArtifact repository
C. reate an AWS Lambda function that checks for new CodeArtifact package versions and starts the Image Builder pipeline if a new version exists
D. reate an AWS Lambda function that checks for new CodeArtifact package versions and starts the Image Builder pipeline if a new version exists

A. dd a health check to the Auto Scaling group to invoke an AWS Lambda function whenever an instance status is impaired
B. onfigure the Auto Scaling group to send a notification to an Amazon SNS topic whenever a failed instance launch occurs
C. reate an Amazon CloudWatch alarm that invokes an AWS Lambda function when a failed Attachinstances Auto Scaling API call is made
D. reate a status check alarm on Amazon EC2 to send a notification to an Amazon SNS topic whenever a status check fail occurs
