• Question 322:

  A SysOps administrator is evaluating Amazon Route 53 DNS options to address concerns about high availability for an on-premises website. The website consists of two servers: a primary active server and a secondary passive server. Route

  53 should route traffic to the primary server if the associated health check returns 2xx or 3xx HTTP codes. All other traffic should be directed to the secondary passive server. The failover record type, set ID. and routing policy have been set

  appropriately for both primary and secondary servers.

  Which next step should be taken to configure Route 53?

  A. Create an A record for each server. Associate the records with the Route 53 HTTP health check.
  B. Create an A record for each server. Associate the records with the Route 53 TCP health check.
  C. Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 HTTP health check.
  D. Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 TCP health check.
  A. Create an A record for each server. Associate the records with the Route 53 HTTP health check.

• Question 323:

  A global gaming company is preparing to launch a new game on AWS. The game runs in multiple AWS Regions on a fleet of Amazon EC2 instances. The instances are in an Auto Scaling group behind an Application Load Balancer (ALB) in each Region. The company plans to use Amazon Route 53 tor DNS services. The DNS configuration must direct users to the Region that is closest to mem and must provide automated failover.

  Which combination of steps should a SysOps administrator take to configure Route 53 to meet these requirements9 {Select TWO.)

  A. Create Amazon CloudWatch alarms that monitor the health of the ALB m each Region Configure Route 53 DNS failover by using a health check that monitors the alarms.
  B. Create Amazon CloudWatch alarms that monitor the hearth of the EC2 instances in each Region. Configure Route 53 DNS failover by using a health check that monitors the alarms.
  C. Configure Route 53 DNS failover by using a health check that monitors the private address of an EC2 instance in each Region.
  D. Configure Route 53 geoproximity routing Specify the Regions that are used for the infrastructure
  E. Configure Route 53 simple routing Specify the continent, country, and state or province that are used for the infrastructure.
  A. Create Amazon CloudWatch alarms that monitor the health of the ALB m each Region Configure Route 53 DNS failover by using a health check that monitors the alarms.
  D. Configure Route 53 geoproximity routing Specify the Regions that are used for the infrastructure

  Explanation Explanation/Reference:Option B is not correct because monitoring the health of the EC2 instances is not sufficient to provide failover as the EC2 instances are in an Auto Scaling group and instances can be added or removed dynamically. Option C is not correct because monitoring the private IP address of an EC2 instance is not sufficient to determine the health of the infrastructure, as the instance may still be running but the application or service on the instance may be unhealthy. Option E is not correct because simple routing does not take into account geographic proximity, which is a requirement in this scenario.

• Question 324:

  A company has many accounts in an organization in AWS Organizations. The company must automate resource provisioning from the organization's management account to the member accounts. Which solution will meet this requirement?

  A. Create an AWS CloudFormation change set. Deploy the change set to all member accounts.
  B. Create an AWS CloudFormation nested stack. Deploy the nested stack to all member accounts.
  C. Create an AWS CloudFormation stack set. Deploy the stack set to all member accounts.
  D. Create an AWS Serverless Application Model (AWS SAM) template. Deploy the template to all member accounts.
  C. Create an AWS CloudFormation stack set. Deploy the stack set to all member accounts.

• Question 325:

  A company's application on EC2 instances relies on a Single-AZ RDS for MySQL DB instance. The SysOps administrator needs to ensure failover to minimize downtime.

  A. Modify the DB instance to be a Multi-AZ DB instance deployment.
  B. Add a read replica in the same Availability Zone where the DB instance is deployed.
  C. Add the DB instance to an Auto Scaling group that has a minimum capacity of 2 and a desired capacity of 2.
  D. Use RDS Proxy to configure a proxy in front of the DB instance.
  A. Modify the DB instance to be a Multi-AZ DB instance deployment.

• Question 326:

  A company runs an application that uses a MySQL database on an Amazon EC2 instance. The EC2 instance has a General Purpose SSD Amazon Elastic Block Store (Amazon EBS) volume. The company made changes to the application

  code and now wants to perform load testing to evaluate the impact of the code changes. A SysOps administrator must create a new MySQL instance from a snapshot of the existing production instance. This new instance needs to perform as

  similarly as possible to the production instance.

  Which restore option meets these requirements?

  A. Use EBS fast snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot.
  B. Use EBS fast snapshot restore to create a new Provisioned IOPS SSD EBS volume from the production snapshot.
  C. Use EBS snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot.
  D. Use EBS snapshot restore to create a new Provisioned IOPS SSD EBS volume from the production snapshot.
  A. Use EBS fast snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot.

• Question 327:

  The company wants to use three On-Demand Instances at all times and additional three Spot Instances when prices drop to a specific threshold, ensuring high availability with minimal management overhead.

  A. Configure a launch template for the Spot Instances. Set the maximum price for the Spot Instances. Configure another launch template for the On-Demand Instances.
  B. Configure a launch template that uses the InstanceMarketOptions property for the Spot Instances and the On-Demand Instances. Set the maximum price for the Spot Instances.
  C. Configure a launch template that uses the MixedInstancesPolicy property for the Spot Instances and the On-Demand Instances. Set the maximum price for the Spot Instances.
  D. Configure a launch template that uses the InstanceMarketOptions property and the MixedInstancesPolicy property for the Spot Instances and the On-Demand Instances. Set the maximum price for the Spot Instances.
  C. Configure a launch template that uses the MixedInstancesPolicy property for the Spot Instances and the On-Demand Instances. Set the maximum price for the Spot Instances.

• Question 328:

  A SysOps administrator needs to give users the ability to upload objects to an Amazon S3 bucket. The SysOps administrator creates a presigned URL and provides the URL to a user, but the user cannot upload an object to the S3 bucket. The presigned URL has not expired, and no bucket policy is applied to the S3 bucket.

  Which of the following could be the cause of this problem?

  A. The user has not properly configured the AWS CLI with their access key and secret access key.
  B. The SysOps administrator does not have the necessary permissions to upload the object to the S3 bucket.
  C. The SysOps administrator must apply a bucket policy to the S3 bucket to allow the user to upload the object.
  D. The object already has been uploaded through the use of the presigned URL, so the presigned URL is no longer valid.
  B. The SysOps administrator does not have the necessary permissions to upload the object to the S3 bucket.

• Question 329:

  A. S3 bucket ACL
  B. AWS Firewall Manager
  C. Amazon Route 53 private hosted zone
  D. Origin access identity (OAI)

• Question 330:

  A SysOps administrator manages the security of accounts in an organization in AWS Organizations. The administrator must implement a solution that applies a base configuration to all accounts when they join the organization.
