AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A company runs an application on an Amazon Elastic Container Service (Amazon ECS) service by using the AWS Fargate launch type. The application consumes messages from an Amazon Simple Queue Service (Amazon SQS) queue. The application can take several minutes to process each message from the queue. When the application processes a message, the application reads a file from an Amazon S3 bucket and processes the data in the file. The application writes the processed output to a second S3 bucket. The company uses Amazon CloudWatch Logs to monitor processing errors and to ensure that the application processes messages successfully.

The SQS queue typically receives a low volume of messages. However, occasionally the queue receives higher volumes of messages. A DevOps engineer needs to implement a solution to reduce the processing time of message bursts.

Which solution will meet this requirement in the MOST cost-effective way?

Options:

A.

Register the ECS service as a scalable target in AWS Application Auto Scaling. Configure a target tracking scaling policy to scale the service in response to the queue size.

B.

Increase the maximum number of messages that Amazon SQS requests to batch messages together. Use long polling to minimize the number of API calls to Amazon SQS during periods of low traffic.

C.

Send messages to an Amazon EventBridge event bus instead of the SQS queue. Replace the ECS service with an EventBridge rule that launches ECS tasks in response to matching events.

D.

Create an Auto Scaling group of EC2 instances. Create a capacity provider in the ECS cluster by using the Auto Scaling group. Change the ECS service to use the EC2 launch type.

Question 2

A company hired a penetration tester to simulate an internal security breach The tester performed port scans on the company ' s Amazon EC2 instances. The company ' s security measures did not detect the port scans.

The company needs a solution that automatically provides notification when port scans are performed on EC2 instances. The company creates and subscribes to an Amazon Simple Notification Service (Amazon SNS) topic.

What should the company do next to meet the requirement?

Options:

A.

Ensure that Amazon GuardDuty is enabled Create an Amazon CloudWatch alarm for detected EC2 and port scan findings. Connect the alarm to the SNS topic.

B.

Ensure that Amazon Inspector is enabled Create an Amazon EventBridge event for detected network reachability findings that indicate port scans Connect the event to the SNS topic.

C.

Ensure that Amazon Inspector is enabled. Create an Amazon EventBridge event for detected CVEs that cause open port vulnerabilities. Connect the event to the SNS topic

D.

Ensure that AWS CloudTrail is enabled Create an AWS Lambda function to analyze the CloudTrail logs for unusual amounts of traffic from an IP address range Connect the Lambda function to the SNS topic.

Question 3

A company has multiple accounts in an organization in AWS Organizations. The company ' s SecOps team needs to receive an Amazon Simple Notification Service (Amazon SNS) notification if any account in the organization turns off the Block Public Access feature on an Amazon S3 bucket. A DevOps engineer must implement this change without affecting the operation of any AWS accounts. The implementation must ensure that individual member accounts in the organization cannot turn off the notification.

Which solution will meet these requirements?

Options:

A.

Designate an account to be the delegated Amazon GuardDuty administrator account. Turn on GuardDuty for all accounts across the organization. In the GuardDuty administrator account, create an SNS topic. Subscribe the SecOps team ' s email address to the SNS topic. In the same account, create an Amazon EventBridge rule that uses an event pattern for GuardDuty findings and a target of the SNS topic.

B.

Create an AWS CloudFormation template that creates an SNS topic and subscribes the SecOps team’s email address to the SNS topic. In the template, include an Amazon EventBridge rule that uses an event pattern of CloudTrail activity for s3:PutBucketPublicAccessBlock and a target of the SNS topic. Deploy the stack to every account in the organization by using CloudFormation StackSets.

C.

Turn on AWS Config across the organization. In the delegated administrator account, create an SNS topic. Subscribe the SecOps team ' s email address to the SNS topic. Deploy a conformance pack that uses the s3-bucket-level-public-access-prohibited AWS Config managed rule in each account and uses an AWS Systems Manager document to publish an event to the SNS topic to notify the SecOps team.

D.

Turn on Amazon Inspector across the organization. In the Amazon Inspector delegated administrator account, create an SNS topic. Subscribe the SecOps team’s email address to the SNS topic. In the same account, create an Amazon EventBridge rule that uses an event pattern for public network exposure of the S3 bucket and publishes an event to the SNS topic to notify the SecOps team.
