  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
