Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 240 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 240
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A solutions architect needs to define a reference architecture for a solution for three-tier applications with web. application, and NoSQL data layers. The reference architecture must meet the following requirements:

• High availability within an AWS Region
• Able to fail over in 1 minute to another AWS Region for disaster recovery
• Provide the most efficient solution while minimizing the impact on the user experience

Which combination of steps will meet these requirements? (Choose three.)

  • A. Use an Amazon Route 53 weighted routing policy set to 100/0 across the two selected Regions. Set Time to Live (TTL) to 1 hour.
  • B. Use an Amazon Route 53 failover routing policy for failover from the primary Region to the disaster recovery Region. Set Time to Live (TTL) to 30 seconds.
  • C. Use a global table within Amazon DynamoDB so data can be accessed in the two selected Regions.
  • D. Back up data from an Amazon DynamoDB table in the primary Region every 60 minutes and then write the data to Amazon S3. Use S3 cross-Region replication to copy the data from the primary Region to the disaster recovery Region. Have a script import the data into DynamoDB in a disaster recovery scenario.
  • E. Implement a hot standby model using Auto Scaling groups for the web and application layers across multiple Availability Zones in the Regions. Use zonal Reserved Instances for the minimum number of servers and On-Demand Instances for any additional resources.
  • F. Use Auto Scaling groups for the web and application layers across multiple Availability Zones in the Regions. Use Spot Instances for the required resources.

To meet the requirements of high availability within an AWS Region, failover to another AWS Region for disaster recovery, and provide an efficient solution while minimizing user impact, the following three steps should be taken: Step B: Use an Amazon Route 53 failover routing policy for failover from the primary Region to the disaster recovery Region. Set Time to Live (TTL) to 30 seconds. By using the failover routing policy in Amazon Route 53, you can configure DNS failover between the primary and disaster recovery Regions. This allows traffic to be redirected to the disaster recovery Region in the event of a failure in the primary Region.

Step E: Implement a hot standby model using Auto Scaling groups for the web and application layers across multiple Availability Zones in the Regions. Use zonal Reserved Instances for the minimum number of servers and On-Demand Instances for any additional resources. By implementing a hot standby model with Auto Scaling groups across multiple Availability Zones in both the primary and disaster recovery Regions, you can ensure high availability within the Region. Using zonal Reserved Instances for the minimum number of servers helps optimize costs, while On-Demand Instances provide flexibility for additional resource provisioning.

Step C: Use a global table within Amazon DynamoDB so data can be accessed in the two selected Regions. Amazon DynamoDB global tables enable automatic multi-region replication, allowing the data to be accessed in both the primary and disaster recovery Regions. This ensures data availability and low-latency access to the data.
