Question #1 Topic 1
A company has a mobile application that makes HTTP API calls to an Application Load Balancer (ALB). The ALB routes requests to an AWS
Lambda function. Many different versions of the application are in use at any given time, including versions that are in testing by a subset of
users. The version of the application is defined in the user-agent header that is sent with all requests to the API.
After a series of recent changes to the API, the company has observed issues with the application. The company needs to gather a metric for
each API operation by response code for each version of the application that is in use. A DevOps engineer has modified the Lambda function to
extract the API operation name, version information from the user-agent header and response code.
Which additional set of actions should the DevOps engineer take to gather the required metrics? Modify the Lambda function to write the API operation name, response code, and version number as a log line to an Amazon CloudWatch Logs log group. Configure a CloudWatch Logs metric filter that increments a metric for each API operation name. Specify response code and application version as dimensions for the metric. Modify the Lambda function to write the API operation name, response code, and version number as a log line to an Amazon CloudWatch Logs log group. Configure a CloudWatch Logs Insights query to populate CloudWatch metrics from the log lines. Specify response code and application version as dimensions for the metric. Configure the ALB access logs to write to an Amazon CloudWatch Logs log group. Modify the Lambda function to respond to the ALB with the API operation name, response code, and version number as response metadata. Configure a CloudWatch Logs metric filter that increments a metric for each API operation name. Specify response code and application version as dimensions for the metric. Configure AWS X-Ray integration on the Lambda function. Modify the Lambda function to create an X-Ray subsegment with the API operation name, response code, and version number. Configure X-Ray insights to extract an aggregated metric for each API operation name and to publish the metric to Amazon CloudWatch. Specify response code and application version as dimensions for the metric.
Question #2 Topic 1
A company provides an application to customers. The application has an Amazon API Gateway REST API that invokes an AWS Lambda function.
On initialization, the Lambda function loads a large amount of data from an Amazon DynamoDB table. The data load process results in long coldstart
times of 8-10 seconds. The DynamoDB table has DynamoDB Accelerator (DAX) configured.
Customers report that the application intermittently takes a long time to respond to requests. The application receives thousands of requests
throughout the day. In the middle of the day, the application experiences 10 times more requests than at any other time of the day. Near the end of
the day, the application's request volume decreases to 10% of its normal total.
A DevOps engineer needs to reduce the latency of the Lambda function at all times of the day.
Which solution will meet these requirements? Configure provisioned concurrency on the Lambda function with a concurrency value of 1. Delete the DAX cluster for the DynamoDB table. Configure reserved concurrency on the Lambda function with a concurrency value of 0. Configure provisioned concurrency on the Lambda function. Configure AWS Application Auto Scaling on the Lambda function with provisioned concurrency values set to a minimum of 1 and a maximum of 100. Configure reserved concurrency on the Lambda function. Configure AWS Application Auto Scaling on the API Gateway API with a reserved concurrency maximum value of 100.
Question #3 Topic 1
A company is adopting AWS CodeDeploy to automate its application deployments for a Java-Apache Tomcat application with an Apache
Webserver. The development team started with a proof of concept, created a deployment group for a developer environment, and performed
functional tests within the application. After completion, the team will create additional deployment groups for staging and production.
The current log level is configured within the Apache settings, but the team wants to change this configuration dynamically when the deployment
occurs, so that they can set different log level configurations depending on the deployment group without having a different application revision
for each group.
How can these requirements be met with the LEAST management overhead and without requiring different script versions for each deployment
group? Tag the Amazon EC2 instances depending on the deployment group. Then place a script into the application revision that calls the metadata service and the EC2 API to identify which deployment group the instance is part of. Use this information to configure the log level settings. Reference the script as part of the AfterInstall lifecycle hook in the appspec.yml file. Create a script that uses the CodeDeploy environment variable DEPLOYMENT_GROUP_ NAME to identify which deployment group the instance is part of. Use this information to configure the log level settings. Reference this script as part of the BeforeInstall lifecycle hook in the appspec.yml file. Create a CodeDeploy custom environment variable for each environment. Then place a script into the application revision that checks this environment variable to identify which deployment group the instance is part of. Use this information to configure the log level settings. Reference this script as part of the ValidateService lifecycle hook in the appspec.yml file. Create a script that uses the CodeDeploy environment variable DEPLOYMENT_GROUP_ID to identify which deployment group the instance is part of to configure the log level settings. Reference this script as part of the Install lifecycle hook in the appspec.yml file.

Question #13 Topic 1
A company has a single AWS account that runs hundreds of Amazon EC2 instances in a single AWS Region. New EC2 instances are launched and
terminated each hour in the account. The account also includes existing EC2 instances that have been running for longer than a week.
The company's security policy requires all running EC2 instances to use an EC2 instance profile. If an EC2 instance does not have an instance
profile attached, the EC2 instance must use a default instance profile that has no IAM permissions assigned.
A DevOps engineer reviews the account and discovers EC2 instances that are running without an instance profile. During the review, the DevOps
engineer also observes that new EC2 instances are being launched without an instance profile.
Which solution will ensure that an instance profile is attached to all existing and future EC2 instances in the Region? Configure an Amazon EventBridge rule that reacts to EC2 RunInstances API calls.

Update the production alias to point to the new version. Configure rollbacks to occur when an alarm is in the ALARM state.
Question #15 Topic 1
To run an application, a DevOps engineer launches an Amazon EC2 instance with public IP addresses in a public subnet. A user data script
obtains the application artifacts and installs them on the instances upon launch. A change to the security classification of the application now
requires the instances to run with no access to the internet. While the instances launch successfully and show as healthy, the application does not
seem to be installed.
Which of the following should successfully install the application while complying with the new rule? Launch the instances in a public subnet with Elastic IP addresses attached. Once the application is installed and running, run a script to disassociate the Elastic IP addresses afterwards. Set up a NAT gateway. Deploy the EC2 instances to a private subnet. Update the private subnet's route table to use the NAT gateway as the default route. Publish the application artifacts to an Amazon S3 bucket and create a VPC endpoint for S3. Assign an IAM instance profile to the EC2 instances so they can read the application artifacts from the S3 bucket. Create a security group for the application instances and allow only outbound traffic to the artifact repository. Remove the security group rule once the install is complete.
Question #16 Topic 1
A development team is using AWS CodeCommit to version control application code and AWS CodePipeline to orchestrate software deployments.
The team has decided to use a remote main branch as the trigger for the pipeline to integrate code changes. A developer has pushed code
changes to the CodeCommit repository, but noticed that the pipeline had no reaction, even after 10 minutes.
Which of the following actions should be taken to troubleshoot this issue? Check that an Amazon EventBridge rule has been created for the main branch to trigger the pipeline. Check that the CodePipeline service role has permission to access the CodeCommit repository. Check that the developer’s IAM role has permission to push to the CodeCommit repository. Check to see if the pipeline failed to start because of CodeCommit errors in Amazon CloudWatch Logs.
Question #17 Topic 1
A company's developers use Amazon EC2 instances as remote workstations. The company is concerned that users can create or modify EC2
security groups to allow unrestricted inbound access.
A DevOps engineer needs to develop a solution to detect when users create unrestricted security group rules. The solution must detect changes to
security group rules in near real time, remove unrestricted rules, and send email notifications to the security team. The DevOps engineer has
created an AWS Lambda function that checks for security group ID from input, removes rules that grant unrestricted access, and sends
notifications through Amazon Simple Notification Service (Amazon SNS).
What should the DevOps engineer do next to meet the requirements? Configure the Lambda function to be invoked by the SNS topic. Create an AWS CloudTrail subscription for the SNS topic. Configure a subscription filter for security group modification events. Create an Amazon EventBridge scheduled rule to invoke the Lambda function.

Question #21 Topic 1
A company has containerized all of its in-house quality control applications. The company is running Jenkins on Amazon EC2 instances, which
require patching and upgrading. The compliance officer has requested a DevOps engineer begin encrypting build artifacts since they contain
company intellectual property.
What should the DevOps engineer do to accomplish this in the MOST maintainable manner? Automate patching and upgrading using AWS Systems Manager on EC2 instances and encrypt Amazon EBS volumes by default. Deploy Jenkins to an Amazon ECS cluster and copy build artifacts to an Amazon S3 bucket with default encryption enabled. Leverage AWS CodePipeline with a build action and encrypt the artifacts using AWS Secrets Manager. Use AWS CodeBuild with artifact encryption to replace the Jenkins instance running on EC2 instances.
Question #22 Topic 1
An IT team has built an AWS CloudFormation template so others in the company can quickly and reliably deploy and terminate an application. The
template creates an Amazon EC2 instance with a user data script to install the application and an Amazon S3 bucket that the application uses to
serve static webpages while it is running.
All resources should be removed when the CloudFormation stack is deleted. However, the team observes that CloudFormation reports an error
during stack deletion, and the S3 bucket created by the stack is not deleted.
How can the team resolve the error in the MOST efficient manner to ensure that all resources are deleted without errors? Add a DelelionPolicy attribute to the S3 bucket resource, with the value Delete forcing the bucket to be removed when the stack is deleted. Add a custom resource with an AWS Lambda function with the DependsOn attribute specifying the S3 bucket, and an IAM role. Write the Lambda function to delete all objects from the bucket when RequestType is Delete. Identify the resource that was not deleted. Manually empty the S3 bucket and then delete it. Replace the EC2 and S3 bucket resources with a single AWS OpsWorks Stacks resource. Define a custom recipe for the stack to create and delete the EC2 instance and the S3 bucket.
Question #23 Topic 1

Question #38 Topic 1
A space exploration company receives telemetry data from multiple satellites. Small packets of data are received through Amazon API Gateway
and are placed directly into an Amazon Simple Queue Service (Amazon SQS) standard queue. A custom application is subscribed to the queue
and transforms the data into a standard format.
Because of inconsistencies in the data that the satellites produce, the application is occasionally unable to transform the data. In these cases, the
messages remain in the SQS queue. A DevOps engineer must develop a solution that retains the failed messages and makes them available to
scientists for review and future processing.
Which solution will meet these requirements? Configure AWS Lambda to poll the SQS queue and invoke a Lambda function to check whether the queue messages are valid. If validation fails, send a copy of the data that is not valid to an Amazon S3 bucket so that the scientists can review and correct the data. When the data is corrected, amend the message in the SQS queue by using a replay Lambda function with the corrected data. Convert the SQS standard queue to an SQS FIFO queue. Configure AWS Lambda to poll the SQS queue every 10 minutes by using an Amazon EventBridge schedule. Invoke the Lambda function to identify any messages with a SentTimestamp value that is older than 5 minutes, push the data to the same location as the application's output location, and remove the messages from the queue. Create an SQS dead-letter queue. Modify the existing queue by including a redrive policy that sets the Maximum Receives setting to 1 and sets the dead-letter queue ARN to the ARN of the newly created queue. Instruct the scientists to use the dead-letter queue to review the data that is not valid. Reprocess this data at a later time. Configure API Gateway to send messages to different SQS virtual queues that are named for each of the satellites. Update the application to use a new virtual queue for any data that it cannot transform, and send the message to the new virtual queue. Instruct the scientists to use the virtual queue to review the data that is not valid. Reprocess this data at a later time.
