NEW QUESTION 132
If you're trying to configure an AWS Elastic Beanstalk worker tier for easy debugging if there are problems finishing queue jobs, what should you configure?
- A. Configure Enhanced Health Reporting
- B. Configure Rolling Deployments.
- C. Configure a Dead Letter Queue
- D. Configure Blue-Green Deployments.
Answer: C
Explanation:
Elastic Beanstalk worker environments support Amazon Simple Queue Service (SQS) dead letter queues. A dead letter queue is a queue where other (source) queues can send messages that for some reason could not be successfully processed. A primary benefit of using a dead letter queue is the ability to sideline and isolate the unsuccessfully processed messages. You can then analyze any messages sent to the dead letter queue to try to determine why they were not successfully processed.

NEW QUESTION 133
You want to build an application that coordinates work across distributed components, and you find Amazon Simple Workflow Service (Amazon SWF) does this easily. You have enabled logging in CloudTrail, but you are unsure about Amazon SWF actions supported. Which of the following actions is NOT supported?
- A. RegisterDomain
- B. RegisterWorkflowType
- C. RegisterActivityType
- D. RegisterWorkflowActivity
Answer: D
Explanation:
Amazon SWF is integrated with AWS CloudTrail, a service that captures API calls made by or on behalf of Amazon SWF and delivers the log files to an Amazon S3 bucket that you specify. The API calls can be made indirectly by using the Amazon SWF console or directly by using the Amazon SWF API.
When CloudTrail logging is enabled, calls made to Amazon SWF actions are tracked in log files.
Amazon SWF records are written together with any other AWS service records in a log file.
CloudTrail determines when to create and write to a new file based on a specified time period and file size.
The following actions are supported:
DeprecateActivityType
DeprecateDomain
DeprecateWorkflowType
RegisterActivityType
RegisterDomain
RegisterWorkflowType

A DevOps Engineer wants to prevent Developers from pushing updates directly to the company's master branch in AWS CodeCommit. These updates should be approved before they are merged.
Which solution will meet these requirements?
- A. Configure an IAM role for the Developers to use feature branches and create a pull request when a feature is complete. Allow CodeCommit to test all code in the feature branches, and issue a new AWS Security Token Service (STS) token allowing a one-time API call to merge the feature branches into the master. Allow an approver to use CodeCommit to view the changes and approve the pull requests.
- B. Configure an IAM role for the Developers with access to CodeCommit and attach an access policy to the CodeCommit repository that denies the Developers role access when the reference is master. Allow Developers to use feature branches and create a pull request when a feature is complete. Allow an approver to use CodeCommit to view the changes and approve the pull requests.
- C. Configure an IAM role for the Developers to use feature branches and create a pull request when a feature is complete. Allow CodeCommit to test all code in the feature branches, and dynamically modify the IAM role to allow merging the feature branches into the master. Allow an approver to use CodeCommit to view the changes and approve the pull requests.
- D. Configure an IAM role for the Developers with access to CodeCommit and an explicit deny for write actions when the reference is the master. Allow Developers to use feature branches and create a pull request when a feature is complete. Allow an approver to use CodeCommit to view the changes and approve the pull requests.

NEW QUESTION 136
Your firm has uploaded a large amount of aerial image data to S3. In the past, in your on-premises environment, you used a dedicated group of servers to process this data and used Rabbit MQ - An open source messaging system to get job information to the servers. Once processed the data would go to tape and be shipped offsite. Your manager told you to stay with the current design, and leverage AWS archival storage and messaging services to minimize cost. Which is correct?
- A. SetupAuto-Scaled workers triggered by queue depth that use spot instances to processmessages in SQS.
Once data is processed, change the storage class of the S3objects to Glacier C- Changethe storage class of the S3 objects to Reduced Redundancy Storage. SetupAuto-Scaled workers triggered by queue depth that use spot instances to processmessages in SQS. Once data is processed, change the storage class of the S3objects to Glacier. - B. UseSQS for passing job messages. Use Cloud Watch alarms to terminate EC2 workerinstances when they become idle. Once data is processed, change the storageclass of the S3 objects to Reduced Redundancy Storage.
- C. Use SNS topassjob messages use Cloud Watch alarms to terminate spot worker instanceswhen they become idle. Once data is processed, change the storage class of theS3 object to Glacier.
Answer: A
Explanation:
Explanation
The best option for reduces costs is Glacier, since anyway in the on-premise location everything was stored on tape. Hence option A is out.
Next SQS should be used, since RabbitMG was used internally. Hence option D is out.
The first step is to leave the objects in S3 and not tamper with that. Hence option B is more suited.
The following diagram shows how SQS is used in a worker span environment

NEW QUESTION 137
Your serverless architecture using AWS API Gateway, AWS Lambda, and AWS DynamoDB experienced a large increase in traffic to a sustained 400 requests per second, and dramatically increased in failure rates. Your requests, during normal operation, last 500 milliseconds on average. Your DynamoDB table did not exceed 50% of provisioned throughput, and Table primary keys are designed correctly. What is the most likely issue?
- A. Your AWS API Gateway Deployment is bottlenecking on request (de)serialization.
- B. You did not request a limit increase on concurrent Lambda function executions.
- C. You used Consistent Read requests on DynamoDB and are experiencing semaphore lock.
- D. Your API Gateway deployment is throttling your requests.
Answer: B
Explanation:
AWS API Gateway by default throttles at 500 requests per second steady-state, and 1000 requests per second at spike. Lambda, by default, throttles at 100 concurrent requests for safety.
At 500 milliseconds (half of a second) per request, you can expect to support 200 requests per second at 100 concurrency. This is less than the 400 requests per second your system now requires. Make a limit increase request via the AWS Support Console.
AWS Lambda: Concurrent requests safety throttle per account -> 100

NEW QUESTION 138
You are a Devops Engineer for your company. Your company is using Opswork stack to rollout a collection of web instances. When the instances are launched, a configuration file need to be setup prior to the launching of the web application hosted on these instances. Which of the following steps would you carry out to ensure this requirement gets fulfilled. Choose 2 answers from the options given below
- A. Ensurethat the Opswork stack is changed to use custom cookbooks
- B. Configurea recipe which sets the configuration file and add it to the Deploy LifeCycleEvent of the specific web layer.
- C. Ensurethat the Opswork stack is changed to use the AWS specific cookbooks
- D. Configurea recipe which sets the configuration file and add it to the ConfigureLifeCycle Event of the specific web layer.
Answer: A,D
Explanation:
Explanation
This is mentioned in the AWS documentation
Configure
This event occurs on all of the stack's instances when one of the following occurs:
* An instance enters or leaves the online state.
* You associate an Elastic IP address with an instance or disassociate one from an instance.
* You attach an Elastic Load Balancing load balancer to a layer, or detach one from a layer.
For example, suppose that your stack has instances A, B, and C, and you start a new instance, D.
After D has finished running its setup recipes, AWS OpsWorks Stacks triggers the Configure event on A, B, C, and D.
If you subsequently stop A, AWS Ops Works Stacks triggers the Configure event on B, C, and D.
AWS OpsWorks Stacks responds to the Configure event by running each layer's Configure recipes, which update the instances' configuration to reflect the current set of online instances. The Configure event is therefore a good time to regenerate configuration files. For example, the HAProxy Configure recipes reconfigure the load balancer to accommodate any changes in the set of online application server instances.
You can also manually trigger the Configure event by using the Configure stack command. For more information on Opswork lifecycle events, please refer to the below URL:

NEW QUESTION 139
A global company with distributed Development teams built a web application using a microservices architecture running on Amazon ECS. Each application service is independent and runs as a service in the ECS cluster. The container build files and source code reside in a private GitHub source code repository. Separate ECS clusters exist for development, testing, and production environments. Developers are required to push features to branches in the GitHub repository and then merge the changes into an environment-specific branch (development, test, or production). This merge needs to trigger an automated pipeline to run a build and a deployment to the appropriate ECS cluster. What should the DevOps Engineer recommend as an automated solution to these requirements?
- A. Create a separate pipeline in AWS CodePipeline for each environment. Trigger each pipeline based on commits to the corresponding environment branch in GitHub. Add a build stage to launch AWS CodeBuild to create the container image from the build file and push it to Amazon ECR. Then add another stage to update the Amazon ECS task and service definitions in the appropriate cluster for that environment.
- B. Create a pipeline in AWS CodePipeline. Configure it to be triggered by commits to the master branch in GitHub. Add a stage to use the Git commit message to determine which environment the commit should be applied to, then call the create-image Amazon ECR command to build the image, passing it to the container build file. Then add a stage to update the ECS task and service definitions in the appropriate cluster for that environment.
- C. Create an AWS CloudFormation stack for the ECS cluster and AWS CodePipeline services. Store the container build files in an Amazon S3 bucket. Use a post-commit hook to trigger a CloudFormation stack update that deploys the ECS cluster. Add a task in the ECS cluster to build and push images to Amazon ECR, based on the container build files in S3.
- D. Create a new repository in AWS CodeCommit. Configure a scheduled project in AWS CodeBuild to synchronize the GitHub repository to the new CodeCommit repository. Create a separate pipeline for each environment triggered by changes to the CodeCommit repository. Add a stage using AWS Lambda to build the container image and push to Amazon ECR. Then add another stage to update the ECS task and service definitions in the appropriate cluster for that environment.

NEW QUESTION 142
A company is using AWS for an application. The Development team must automate its deployments. The team has set up an AWS CodePipeline to deploy the application to Amazon EC2 instances by using AWS CodeDeploy after it has been built using the AWS CodeBuild service.
The team would like to add automated testing to the pipeline to confirm that the application is healthy before deploying it to the next stage of the pipeline using the same code. The team requires a manual approval action before the application is deployed, even if the test is successful. The testing and approval must be accomplished at the lowest costs, using the simplest management solution.
Which solution will meet these requirements?
- A. Create a new pipeline that uses a source action that gets the code from the same repository as the first pipeline. Add a deploy action to deploy the code to a test environment. Use a test action using AWS Lambda to test the deployment. Add a manual approval action by using Amazon SNS to notify the team, and add a deploy action to deploy the application to the next stage.
- B. Add a test action after the last deploy action of the pipeline. Configure the action to use CodeBuild to perform the required tests. If these tests are successful, mark the action as successful. Add a manual approval action that uses Amazon SNS to notify the team, and add a deploy action to deploy the application to the next stage.
- C. Add a manual approval action after the last deploy action of the pipeline. Use Amazon SNS to inform the team of the stage being triggered. Next, add a test action using CodeBuild to do the required tests.
At the end of the pipeline, add a deploy action to deploy the application to the next stage. - D. Add a test action after the last deployment action.

NEW QUESTION 144
Your company uses an application hosted in AWS which conists of EC2 Instances. The logs of the EC2
instances need to be processed and analyzed in real time, since this is a requirement from the IT Security
department. Which of the following can be used to process the logs in real time.
- A. UseAmazon Glacier to store the logs and then use Amazon Kinesis to process andanalyze the logs in
real time - B. Useanother EC2 Instance with a larger instance type to process the logs
- C. UseCloudwatch logs to process and analyze the logs in real time
- D. UseAmazon S3 to store the logs and then use Amazon Kinesis to process and analyzethe logs in real
time
Answer: D
Explanation:
Explanation
The AWS Documentation mentions the below
Real-time metrics and reporting
You can use data collected into Kinesis Streams for simple data analysis and reporting in real time. For
example, your data-processing application can work on metrics and reporting for system and application logs
as the data is streaming in, rather than wait to receive batches of data.
Real-time data analytics
This combines the power of parallel processing with the value of real-time data. For example, process website
clickstreams in real time, and then analyze site usability engagement using multiple different Kinesis Streams
applications running in parallel.
Amazon Glacier is meant for Archival purposes and should not be used for storing the logs for real time
processing.

to an email type delivery on this SNS Topic.
Answer: B
Explanation:
Explanation
AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk
auditing of your AWS account. Actions taken by a user, role, or an AWS service are recorded as events in
CloudTrail. Events include actions taken in the AWS Management Console, AWS Command Line Interface,
and AWS SDKs and APIs.
Visibility into your AWS account activity is a key aspect of security and operational best practices. You can
use CloudTrail to view, search, download, archive, analyze,
and respond to account activity across your AWS infrastructure. You can identify who or what took which
action, what resources were acted upon, when the event occurred, and other details to help you analyze and
respond to activity in your AWS account.
