Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 93 discussion

Exam question from Amazon's AWS Certified DevOps Engineer - Professional DOP-C02
Question #: 93
Topic #: 1
[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

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 team needs a strategy for failover and disaster recovery.

Which combination of deployment strategies will meet these requirements? (Choose two.)

  • A. 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 disaster.
  • B. Create an Amazon Aurora global database in two Regions as the data store. In the event of a failure, promote the secondary Region as the primary for the application.
  • C. Create an Amazon Aurora multi-master cluster across multiple Regions as the data store. Use a Network Load Balancer to balance the database traffic in different Regions.
  • D. 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.
  • E. Set up the application in 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.

Amazon Aurora clusters are designed to be region-specific, meaning that an Aurora DB cluster is limited to a single AWS region. However, you can use Amazon Aurora Global Database to span multiple AWS regions. But Amazon Aurora clusters can span across multiple AZs. An AWS Auto Scaling group cannot span multiple regions. Each Auto Scaling group is limited to a single AWS region. However, within that region, an Auto Scaling group can span multiple Availability Zones to ensure high availability and fault tolerance.

B and D are correct: <needs a strategy for failover and disaster recovery> means global table or db cluster and route53 fail-over policy A and C: These options mention spanning an Amazon Aurora cluster across multiple region. This is not true. A cluster can span across multiple AZs, not regions. The only Aurora solution that can span multiple regions is global table, which includes multiple clusters. E: No mention of Route 53 failover-based routing

between ABC, choose B. A is wrong because “Amazon Aurora cluster in one Availability Zone across multiple Regions” is nonsense. C is incorrect too because Aurora multi-master cluster can't be across multiple regions between DE, choose D because using Route 53 failover-based routing makes sense. E is wrong Auto Scaling group can't be multi-region
