Question 7

A company is migrating its public-facing software to AWS. The company plans to use Amazon EC2 to run application code and Amazon RDS to store all application data. The company wants to primarily use one Region with failover capabilities to a secondary Region and Amazon Route 53 to route traffic. The RPO is 2 hours and the RTO is 4 hours.

Which combination of steps should be used to meet these requirements while MINIMIZING cost? (Choose three.)

  • ○

    Create an AWS CloudFormation template to provision the application server and database instance in a single Region.
  • ○

    Create an AWS CloudFormation template to provision the application tier of the application and a multi-Region database instance.
  • ○

    Configure Amazon CloudWatch Events rules to run every hour. Trigger AWS Lambda functions to create an RDS snapshot and copy it to the secondary Region.
  • ○

    Configure Amazon CloudWatch Events rules to run every 3 hours. Trigger AWS Lambda functions to create an RDS snapshot and copy it to the secondary Region.
  • ○

    In the event of a failure, deploy a new AWS CloudFormation stack in a secondary region to provision the application resources and a new RDS instance using the copied snapshot and a Route 53 failover routing policy.
  • ○

    In the event of a failure, deploy a new AWS CloudFormation stack in a secondary region to provision the application resources and a replica of the RDS database using the copied snapshot and a Route 53 latency-based routing policy.
Question 8

A company is implementing an Amazon ECS cluster to run its workload. The company architecture will run multiple ECS services on the cluster, with an Application Load Balancer on the front end, using multiple target groups to route traffic. The Application Development team has been struggling to collect logs that must be collected and sent to an Amazon S3 bucket for near-real time analysis What must the DevOps Engineer configure in the deployment to meet these requirements? (Choose three.)

Select all that apply, then click Submit answer.

  • ○

    Install the Amazon CloudWatch Logs logging agent on the ECS instances. Change the logging driver in the ECS task definition to 'awslogs'.
  • ○

    Download the Amazon CloudWatch Logs container instance from AWS and configure it as a task. Update the application service definitions to include the logging task.
  • ○

    Use Amazon CloudWatch Events to schedule an AWS Lambda function that will run every 60 seconds running the create-export -task CloudWatch Logs command, then point the output to the logging S3 bucket.
  • ○

    Enable access logging on the Application Load Balancer, then point it directly to the S3 logging bucket.
  • ○

    Enable access logging on the target groups that are used by the ECS services, then point it directly to the S3 logging bucket.
  • ○

    Create an Amazon Kinesis Data Firehose with a destination of the S3 logging bucket, then create an Amazon CloudWatch Logs subscription filter for Kinesis.
Question 9

You work for an insurance company and are responsible for the day-to-day operations of your company's online quote system used to provide insurance quotes to members of the public. Your company wants to use the application logs generated by the system to better understand customer behavior. Industry, regulations also require that you retain all application logs for the system indefinitely in order to investigate fraudulent claims in the future. You have been tasked with designing a log management system with the following requirements:

- All log entries must be retained by the system, even during unplanned instance failure.

- The customer insight team requires immediate access to the logs from the past seven days.

- The fraud investigation team requires access to all historic logs, but will wait up to 24 hours before these logs are available.

How would you meet these requirements in a cost-effective manner? (Choose three.)

Select all that apply, then click Submit answer.

  • ○

    Configure your application to write logs to the instance's ephemeral disk, because this storage is free and has good write performance. Create a script that moves the logs from the instance to Amazon 53 once an hour.
  • ○

    Write a script that is configured to be executed when the instance is stopped or terminated and that will upload any remaining logs on the instance to Amazon S3.
  • ○

    Create an Amazon S3 lifecycle configuration to move log files from Amazon S3 to Amazon Glacier after seven days.
  • ○

    Configure your application to write logs to the instance's default Amazon EBS boot volume, because this storage already exists. Create a script that moves the logs from the instance to Amazon 53 once an hour.
  • ○

    Configure your application to write logs to a separate Amazon EBS volume with the "delete on termination" field set to false. Create a script that moves the logs from the instance to Amazon S3 once an hour.
  • ○

    Create a housekeeping script that runs on a T2 micro instance managed by an Auto Scaling group for high availability. The script uses the AWS API to identify any unattached Amazon EBS volumes containing log files. Your housekeeping script will mount the Amazon EBS volume, upload all logs to Amazon S3, and then delete the volume.
