AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A company has developed an AWS Lambda function that handles orders received through an API. The company is using AWS CodeDeploy to deploy the Lambda function as the final stage of a CI/CD pipeline.

A DevOps engineer has noticed there are intermittent failures of the ordering API for a few seconds after deployment. After some investigation the DevOps engineer believes the failures are due to database changes not having fully propagated before the Lambda function is invoked

How should the DevOps engineer overcome this?

Options:

A.

Add a BeforeAllowTraffic hook to the AppSpec file that tests and waits for any necessary database changes before traffic can flow to the new version of the Lambda function.

B.

Add an AfterAlIowTraffic hook to the AppSpec file that forces traffic to wait for any pending database changes before allowing the new version of the Lambda function to respond.

C.

Add a BeforeAllowTraffic hook to the AppSpec file that tests and waits for any necessary database changes before deploying the new version of the Lambda function.

D.

Add a validateService hook to the AppSpec file that inspects incoming traffic and rejects the payload if dependent services such as the database are not yet ready.

Question 2

A DevOps engineer needs to back up sensitive Amazon S3 objects that are stored within an S3 bucket with a private bucket policy using S3 cross-Region replication functionality. The objects need to be copied to a target bucket in a different AWS Region and account.

Which combination of actions should be performed to enable this replication? (Choose three.)

Options:

A.

Create a replication IAM role in the source account

B.

Create a replication I AM role in the target account.

C.

Add statements to the source bucket policy allowing the replication IAM role to replicate objects.

D.

Add statements to the target bucket policy allowing the replication IAM role to replicate objects.

E.

Create a replication rule in the source bucket to enable the replication.

F.

Create a replication rule in the target bucket to enable the replication.

Question 3

A company sends its AWS Network Firewall flow logs to an Amazon S3 bucket. The company then analyzes the flow logs by using Amazon Athena. The company needs to transform the flow logs and add additional data before the flow logs are delivered to the existing S3 bucket. Which solution will meet these requirements?

Options:

A.

Create an AWS Lambda function to transform the data and to write a new object to the existing S3 bucket. Configure the Lambda function with an S3 trigger for the existing S3 bucket. Specify all object create events for the event type. Acknowledge the recursive invocation.

B.

Enable Amazon EventBridge notifications on the existing S3 bucket. Create a custom EventBridge event bus. Create an EventBridge rule that is associated with the custom event bus. Configure the rule to react to all object create events for the existing S3 bucket and to invoke an AWS Step Functions workflow. Configure a Step Functions task to transform the data and to write the data into a new S3 bucket.

C.

Create an Amazon EventBridge rule that is associated with the default EventBridge event bus. Configure the rule to react to all object create events for the existing S3 bucket. Define a new S3 bucket as the target for the rule. Create an EventBridge input transformation to customize the event before passing the event to the rule target.

D.

Create an Amazon Data Firehose delivery stream that is configured with an AWS Lambda transformer. Specify the existing S3 bucket as the destination. Change the Network Firewall logging destination from Amazon S3 to Firehose.
