3. Question 903 · 1017 in bank

   A company is designing its production application's disaster recovery (DR) strategy. The application is backed by a MySQL database on an Amazon Aurora cluster in the us-east-1 Region. The company has chosen the us-west-1 Region as its DR Region. The company's target recovery point objective (RPO) is 5 minutes and the target recovery time objective (RTO) is 20 minutes. The company wants to minimize configuration changes. Which solution will meet these requirements with the MOST operational efficiency?

   • ACreate an Aurora read replica in us-west-1 similar in size to the production application's Aurora MySQL cluster writer instance.
   • BConvert the Aurora cluster to an Aurora global database. Configure managed failover.
   • CCreate a new Aurora cluster in us-west-1 that has Cross-Region Replication.
   • DCreate a new Aurora cluster in us-west-1. Use AWS Database Migration Service (AWS DMS) to sync both clusters.

   Show answer

   Answer: B

   Explanation

   Answer:B https://aws.amazon.com/rds/aurora/global-database/ Cross-Region disaster recovery If your primary Region suffers a performance degradation or outage, you can promote one of the secondary Regions to take read/write responsibilities. An Aurora cluster can recover in less than 1 minute, even in the event of a complete Regional outage. This provides your application with an effective recovery point objective (RPO) of 1 second and a recovery time objective (RTO) of less than 1 minute, providing a strong foundation for a global business continuity plan.

6. Question 906 · 1017 in bank

   A company is migrating five on-premises applications to VPCs in the AWS Cloud. Each application is currently deployed in isolated virtual networks on premises and should be deployed similarly in the AWS Cloud. The applications need to reach a shared services VPC. All the applications must be able to communicate with each other. If the migration is successful, the company will repeat the migration process for more than 100 applications. Which solution will meet these requirements with the LEAST administrative overhead?

   • ADeploy software VPN tunnels between the application VPCs and the shared services VPC. Add routes between the application VPCs in their subnets to the shared services VPC.
   • BDeploy VPC peering connections between the application VPCs and the shared services VPC. Add routes between the application VPCs in their subnets to the shared services VPC through the peering connection.
   • CDeploy an AWS Direct Connect connection between the application VPCs and the shared services VPAdd routes from the application VPCs in their subnets to the shared services VPC and the applications VPCs. Add routes from the shared services VPC subnets to the applications VPCs.
   • DDeploy a transit gateway with associations between the transit gateway and the application VPCs and the shared services VPC. Add routes between the application VPCs in their subnets and the application VPCs to the shared services VPC through the transit gateway.

7. Question 907 · 1017 in bank

   A company is running an SMB file server in its data center. The file server stores large files that are accessed frequently for the first few days after the files are created. After 7 days the files are rarely accessed. The total data size is increasing and is close to the company's total storage capacity. A solutions architect must increase the company's available storage space without losing low-latency access to the most recently accessed files. The solutions architect must also provide file lifecycle management to avoid future storage issues. Which solution will meet these requirements?

   • AUse AWS DataSync to copy data that is older than 7 days from the SMB file server to AWS.
   • BCreate an Amazon S3 File Gateway to extend the company's storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days.
   • CCreate an Amazon FSx for Windows File Server file system to extend the company's storage space.
   • DInstall a utility on each user's computer to access Amazon S3. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.

   Show answer

   Answer: B

   Explanation

   Answer directly points towards file gateway with lifecycles, D is wrong because utility function is vague and there is no need for flexible storage.
