AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A DevOps engineer is researching the least expensive way to implement an image batch processing cluster on AWS. The application cannot run in Docker containers and must run on Amazon EC2. The batch job stores checkpoint data on an NFS volume and can tolerate interruptions. Configuring the cluster software from a generic EC2 Linux image takes 30 minutes.

What is the MOST cost-effective solution?

Options:

A.

Use Amazon EFS (or checkpoint data. To complete the job, use an EC2 Auto Scaling group and an On-Demand pricing model to provision EC2 instances temporally.

B.

Use GlusterFS on EC2 instances for checkpoint data. To run the batch job configure EC2 instances manually When the job completes shut down the instances manually.

C.

Use Amazon EFS for checkpoint data Use EC2 Fleet to launch EC2 Spot Instances and utilize user data to configure the EC2 Linux instance on startup.

D.

Use Amazon EFS for checkpoint data Use EC2 Fleet to launch EC2 Spot Instances Create a custom AMI for the cluster and use the latest AMI when creating instances.

Question 2

A video-sharing company stores its videos in Amazon S3. The company has observed a sudden increase in video access requests, but the company does not know which videos are most popular. The company needs to identify the general access pattern for the video files. This pattern includes the number of users who access a certain file on a given day, as well as the numb A DevOps engineer manages a large commercial website that runs on Amazon EC2 The website uses Amazon Kinesis Data Streams to collect and process web togs The DevOps engineer manages the Kinesis consumer application, which also runs on Amazon EC2

Sudden increases of data cause the Kinesis consumer application to (all behind and the Kinesis data streams drop records before the records can be processed The DevOps engineer must implement a solution to improve stream handling

Which solution meets these requirements with the MOST operational efficiency ' '

er of pull requests for certain files.

How can the company meet these requirements with the LEAST amount of effort?

Options:

A.

Activate S3 server access logging. Import the access logs into an Amazon Aurora database. Use an Aurora SQL query to analyze the access patterns.

B.

Activate S3 server access logging. Use Amazon Athena to create an external table with the log files. Use Athena to create a SQL query to analyze the access patterns.

C.

Invoke an AWS Lambda function for every S3 object access event. Configure the Lambda function to write the file access information, such as user. S3 bucket, and file key, to an Amazon Aurora database. Use an Aurora SQL query to analyze the access patterns.

D.

Record an Amazon CloudWatch Logs log message for every S3 object access event. Configure a CloudWatch Logs log stream to write the file access information, such as user, S3 bucket, and file key, to an Amazon Kinesis Data Analytics for SQL application. Perform a sliding window analysis.

Question 3

A company deploys an application to two AWS Regions. The application creates and stores objects in an Amazon S3 bucket that is in the same Region as the application. Both deployments of the application need to have access to all the objects and their metadata from both Regions. The company has configured two-way replication between the S3 buckets and has enabled S3 Replication metrics on each S3 bucket.

A DevOps engineer needs to implement a solution that retries the replication process if an object fails to replicate.

Which solution will meet these requirements?

Options:

A.

Create an Amazon EventBridge rule that listens to S3 event notifications for failed replication events. Create an AWS Lambda function that downloads the failed replication object and then runs a PutObject command for the object to the destination bucket. Configure the EventBridge rule to invoke the Lambda function to handle the object that failed to replicate.

B.

Create an Amazon Simple Queue Service (Amazon SQS) queue. Configure S3 event notifications to send failed replication notifications to the SQS queue. Create an AWS Lambda function that downloads the failed replication object and then runs a PutObject command for the object to the destination bucket. Configure the Lambda function to poll the queue for notifications to process.

C.

Create an Amazon EventBridge rule that listens to S3 event notifications for failed replications. Create an AWS Lambda function that downloads the failed replication object and then runs a PutObject command for the object to the destination bucket.

D.

Create an AWS Lambda function that will use S3 Batch Operations to retry the replication on the existing object for a failed replication. Configure S3 event notifications to send failed replication notifications to the Lambda function.
