NEW QUESTION # 530
A company is implementing a well-architected design for its globally accessible API stack. The design needs to ensure both high reliability and fast response times for users located in North America and Europe.
The API stack contains the following three tiers:
* Amazon API Gateway
* AWS Lambda
* Amazon DynamoDB
Which solution will meet the requirements?

  • A. Configure Amazon Route 53 to point to API Gateway APIs in North America and Europe using latency-based routing and health checks. Configure the APIs to forward requests to a Lambda function in that Region. Configure the Lambda functions to retrieve and update the data in a DynamoDB global table.
  • B. Configure Amazon Route 53 to point to API Gateway API in North America using latency-based routing. Configure the API to forward requests to the Lambda function in the Region nearest to the user.
    Configure the Lambda function to retrieve and update the data in a DynamoDB table.
  • C. Configure Amazon Route 53 to point to API Gateway in North America, create a disaster recovery API in Europe, and configure both APIs to forward requests to the Lambda functions in that Region.
    Retrieve the data from a DynamoDB global table. Deploy a Lambda function to check the North America API health every 5 minutes. In the event of a failure, update Route 53 to point to the disaster recovery API.
  • D. Configure Amazon Route 53 to point to API Gateway APIs in North America and Europe using health checks. Configure the APIs to forward requests to a Lambda function in that Region. Configure the Lambda functions to retrieve and update the data in a DynamoDB table in the same Region as the Lambda function.

Answer: D

NEW QUESTION # 532
A DevOps Engineer is building a multi-stage pipeline with AWS CodePipeline to build, verify, stage, test, and deploy an application. There is a manual approval stage required between the test and deploy stages. The development team uses a team chat tool with webhook support.
How can the Engineer configure status updates for pipeline activity and approval requests to post to the chat tool?

  • A. Create an AWS CloudWatch Logs subscription that filters on "detail-type": "CodePipeline Pipeline Execution State Change." Forward that to an Amazon SNS topic. Add the chat webhook URL to the SNS topic as a subscriber and complete the subscription validation.
  • B. Create an AWS CloudWatch Events rule that filters on "CodePipeline Pipeline Execution State Change." Forward that to an Amazon SNS topic. Subscribe an AWS Lambda function to the Amazon SNS topic and have it forward the event to the chat webhook URL.
  • C. Modify the pipeline code to send event details to the chat webhook URL at the end of each stage.
    Parametrize the URL so each pipeline can send to a different URL based on the pipeline environment.
  • D. Create an AWS Lambda function that is triggered by the updating of AWS CloudTrail events. When a
    "CodePipeline Pipeline Execution State Change" event is detected in the updated events, send the event details to the chat webhook URL.

Answer: B


NEW QUESTION # 533
An Application team has three environments for their application: development, pre-production, and production. The team recently adopted AWS CodePipeline. However, the team has had several deployments of misconfigured or nonfunctional development code into the production environment, resulting in user disruption and downtime. The DevOps Engineer must review the pipeline and add steps to identify problems with the application before it is deployed.
What should the Engineer do to identify functional issues during the deployment process? (Choose two.)

  • A. Use Amazon Inspector to add a test action to the pipeline. Use the Amazon Inspector Runtime Behavior Analysis Inspector rules package to check that the deployed code complies with company security standards before deploying it to production.
  • B. Create an AWS CodeDeploy action in the pipeline with a deployment configuration that automatically deploys the application code to a limited number of instances. The action then pauses the deployment so that the QA team can review the application functionality. When the review is complete, CodeDeploy resumes and deploys the application to the remaining production Amazon EC2 instances.
  • C. Add an AWS CodeDeploy action in the pipeline to deploy the latest version of the development code to pre-production. Add a manual approval action in the pipeline so that the QA team can test and confirm the expected functionality. After the manual approval action, add a second CodeDeploy action that deploys the approved code to the production environment.
  • D. Using AWS CodeBuild to add a test action to the pipeline to replicate common user activities and ensure that the results are as expected before progressing to production deployment.
  • E. After the deployment process is complete, run a testing activity on an Amazon EC2 instance in a different region that accesses the application to simulate user behavior if unexpected results occur, the testing activity sends a warning to an Amazon SNS topic. Subscribe to the topic to get updates.

Answer: A,B


NEW QUESTION # 534
You are designing a system which needs, at minumum, 8 m4.large instances operating to service traffic. When designing a system for high availability in the us-east-1 region, which has 6 Availability Zones, you company needs to be able to handle death of a full availability zone. How should you distribute the servers, to save as much cost as possible, assuming all of the EC2 nodes are properly linked to an ELB?
Your VPC account can utilize us-east-1's AZ's a through f, inclusive.

  • A. 2 servers in each of AZ's a through e, inclusive.
  • B. 8 servers in each of AZ's a and b.
  • C. 3 servers in each of AZ's a through d, inclusive.
  • D. 4 servers in each of AZ's a through c, inclusive.

Answer: A

Explanation:
You need to design for N+1 redundancy on Availability Zones. ZONE_COUNT = (REQUIRED_INSTANCES / INSTANCE_COUNT_PER_ZONE) + 1. To minimize cost, spread the instances across as many possible zones as you can. By using a though e, you are allocating
5 zones. Using 2 instances, you have 10 total instances. If a single zone fails, you have 4 zones left, with 2 instances each, for a total of 8 instances. By spreading out as much as possible, you have increased cost by only 25% and significantly de-risked an availability zone failure.
