Question 5

An online retail company based in the United States plans to expand its operations to Europe and Asia in the next six months. Its product currently runs on

Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. All data is stored in an Amazon Aurora database instance.

When the product is deployed in multiple regions, the company wants a single product catalog across all regions, but for compliance purposes, its customer information and purchases must be kept in each region.

How should the company meet these requirements with the LEAST amount of application changes?

Options:

Use Amazon Redshift for the product catalog and Amazon DynamoDB tables for the customer information and purchases.

Use Amazon DynamoDB global tables for the product catalog and regional tables for the customer information and purchases

Use Aurora with read replicas for the product catalog and additional local Aurora instances in each region for the customer information and purchases.

Use Aurora for the product catalog and Amazon DynamoDB global tables for the customer information and purchases.

Question 6

A Development team is currently using AWS CodeDeploy to deploy an application revision to an Auto Scaling group. If the deployment process fails, it must be rolled back automatically and a notification must be sent.

What is the MOST effective configuration that can satisfy all of the requirements?

Options:

Create Amazon CloudWatch Events rules for CodeDeploy operations. Configure a CloudWatch Events rule to send out an Amazon SNS message when the deployment fails. Configure CodeDeploy to automatically roll back when the deployment fails.

Use available Amazon CloudWatch metrics for CodeDeploy to create CloudWatch alarms. Configure CloudWatch alarms to send out an Amazon SNS message when the deployment fails. Use AWS CLI to redeploy a previously deployed revision.

Configure a CodeDeploy agent to create a trigger that will send notification to Amazon SNS topics when the deployment fails. Configure CodeDeploy to automatically roll back when the deployment fails.

Use AWS CloudTrail to monitor API calls made by or on behalf of CodeDeploy in the AWS account. Send an Amazon SNS message when deployment fails. Use AWS CLI to redeploy a previously deployed revision.

Question 7

A company requires an RPO of 2 hours and an RTO of 10 minutes for its data and application at all times An application uses a MySQL database and Amazon EC2 web servers. The development learn needs a strategy for failover and disaster recovery

Which combination of deployment strategies will meet these requirements? {Select TWO)

Options:

Create an Amazon Aurora cluster in one Availability Zone across multiple Regions as the data store Use Aurora's automatic recovery capabilities in the event of a discluster.

Create an Amazon Aurora global database m two Regions as the data store In the event of a failure, promote the secondary Region as the master for the application

Create an Amazon Aurora multi-master cluster across multiple Regions as the data store Use an Network Load Balancer to balance the database traffic in different Regions.

Set up the application in two Regions and use Amazon Route 53 failover-based routing that points to the Application Load Balancers in both Regions Use health checks to determine the availability in a given Region. Use Auto Scaling groups in each Region to adjust capacity based on demand

Set up the application m two Regions and use a multi-Region Auto Scaling group behind Application Load Balancers to manage the capacity based on demand in the event of a disaster, adjust the Auto Scaling group's desired instance count to increase baseline capacity in the failover Region.

Question 8

A company is building a solution for storing files containing Personally Identifiable Information (PII) on AWS.

Requirements state:

*All data must be encrypted at rest and in transit.

*All data must be replicated in at least two locations that are at least 500 miles apart.

Which solution meets these requirements?

Options:

Create primary and secondary Amazon S3 buckets in two separate Availability Zones that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce Amazon S3 SSE-C on all objects uploaded to the bucket. Configure cross-region replication between the two buckets.

Create primary and secondary Amazon S3 buckets in two separate AWS Regions that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce S3-Managed Keys (SSE-S3) on all objects uploaded to the bucket. Configure cross-region replication between the two buckets.

Create primary and secondary Amazon S3 buckets in two separate AWS Regions that are at least 500 miles apart. Use an IAM role to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce Amazon S3-Managed Keys (SSE-S3) on all objects uploaded to the bucket. Configure cross- region replication between the two buckets.

Create primary and secondary Amazon S3 buckets in two separate Availability Zones that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce AWS KMS encryption on all objects uploaded to the bucket. Configure cross-region replication between the two buckets. Create a KMS Customer Master Key (CMK) in the primary region for encrypting objects.
