• Question 625:

  With Amazon Elastic MapReduce (Amazon EMR) you can analyze and process vast amounts of data. The cluster is managed using an open-source framework called Hadoop. You have set up an application to run Hadoop jobs. The

  application reads data from DynamoDB and generates a temporary file of 100 TBs.

  The whole process runs for 30 minutes and the output of the job is stored to S3.

  Which of the below mentioned options is the most cost effective solution in this case?

  A. Use Spot Instances to run Hadoop jobs and configure them with EBS volumes for persistent data storage.
  B. Use Spot Instances to run Hadoop jobs and configure them with ethereal storage for output file storage.
  C. Use an on demand instance to run Hadoop jobs and configure them with EBS volumes for persistent storage.
  D. Use an on demand instance to run Hadoop jobs and configure them with ephemeral storage for output file storage.
  B. Use Spot Instances to run Hadoop jobs and configure them with ethereal storage for output file storage.

• Question 626:

  Amazon EC2 provides a repository of public data sets that can be seamlessly integrated into AWS cloud-based applications. What is the monthly charge for using the public data sets?

  A. A 1-time charge of 10$ for all the datasets.
  B. 1$ per dataset per month
  C. 10$ per month for all the datasets
  D. There is no charge for using the public data sets
  D. There is no charge for using the public data sets

• Question 627:

  A company has a web application that uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. A recent marketing campaign has increased demand. Monitoring software reports that many requests have significantly longer response times than before the marketing campaign.

  A solutions architect enabled Amazon CloudWatch Logs for API Gateway and noticed that errors are occurring on 20% of the requests. In CloudWatch, the Lambda function Throttles metric represents 1% of the requests and the Errors metric represents 10% of the requests. Application logs indicate that, when errors occur, there is a call to DynamoDB.

  What change should the solutions architect make to improve the current response times as the web application becomes more popular?

  A. Increase the concurrency limit of the Lambda function
  B. Implement DynamoDB auto scaling on the table
  C. Increase the API Gateway throttle limit
  D. Re-create the DynamoDB table with a better-partitioned primary index
  B. Implement DynamoDB auto scaling on the table

• Question 628:

  A company is running a custom database in the AWS Cloud. The database uses Amazon EC2 for compute and uses Amazon Elastic Block Store (Amazon EBS) for storage. The database runs on the latest generation of EC2 instances and

  uses a General Purpose SSD (gp2) EBS volume for data.

  The current data volume has the following characteristics:

  The volume is 512 GB in size.

  The volume never goes above 256 GB utilization.

  The volume consistently uses around 1,500 IOPS.

  A solutions architect needs to conduct an analysis of the current database storage layer and make a recommendation about ways to reduce cost. Which solution will provide the MOST cost savings without impacting the performance of the database?

  A. Convert the data volume to the Cloud HDD (sc1) type. Leave the volume as 512 GB. Set the volume IOPS to 1,500.
  B. Convert the data volume to the Provisioned IOPS SSD (io2) type. Resize the volume to 256 GB. Set the volume IOPS to 1,500.
  C. Convert the data volume to the Provisioned IOPS SSD (io2) Block Express type. Leave the volume as 512 GB. Set the volume IOPS to 1,500.
  D. Convert the data volume to the General Purpose SSD (gp3) type. Resize the volume to 256 GB. Set the volume IOPS to 1,500.
  C. Convert the data volume to the Provisioned IOPS SSD (io2) Block Express type. Leave the volume as 512 GB. Set the volume IOPS to 1,500.

• Question 629:

  A company is using a single AWS Region (or its ecommerce website. The website includes a web application that runs on several Amazon EC2 instances behind an Application Load Balancer (ALB). The website also includes an Amazon DynamoDB table. A custom domain name in Amazon Route 53 is linked to the ALB. The company created an SSL/TLS certificate in AWS Certificate Manager (ACM) and attached the certificate to the ALB. The company is not using a content delivery network as part of its design.

  The company wants to replicate its entire application stack in a second Region to provide disaster recovery, plan for future growth, and provide improved access time to users. A solutions architect needs to implement a solution that achieves these goals and minimizes administrative overhead.

  Which combination of steps should the solutions architect take to meet these requirements? (Select THREE.)

  A. Create an AWS Cloud Formation template for the current infrastructure design. Use parameters for important system values, including Region. Use the CloudFormation template to create the new infrastructure in the second Region.
  B. Use the AWS Management Console to document the existing infrastructure design in the first Region and to create the new infrastructure in the second Region.
  C. Update the Route 53 hosted zone record for the application to use weighted routing.Send 50% of the traffic to the ALB in each Region.
  D. Update the Route 53 hosted zone record for the application to use latency-based routing. Send traffic to the ALB in each Region.
  E. Update the configuration of the existing DynamoDB table by enabling DynamoDB Streams Add the second Region to create a global table.
  F. Create a new DynamoDB table. Enable DynamoDB Streams for the new table. Add the second Region to create a global table. Copy the data from the existing DynamoDB table to the new table as a one-time operation.
