You are a cloud architect responsible for designing a multiple availability zone configuration for the organization’s geographically dispersed clouds. You must provide the ability for services to survive a failure at the data center or site level. The primary requirement is to provide for automated site recovery.
What is a key consideration when satisfying this requirement?
A . The DR site should have a large number of small volumes to decrease the mount time.
B . The DR solution should support heterogeneous hardware across both sites.
C . Automated site recovery should orchestrate the site failover processes only.
D . The storage volumes in the DR site should match the number and size in the primary site.
Answer: B

Key Considerations for Automated Site Recovery
• When implementing automated site recovery, it is important to have automated orchestration of site failover and failback process to reduce recovery time
• Evaluate the replication options (VM-based replication or array-based replication) that best suit for the organization’s requirements for DR.
• The automated site recovery solution should support heterogeneous hardware across the sites.
• One of the key design factors of this approach is that a recovery site must have sufficient available capacity to host workloads after a disaster at the primary site.
• In the DR, it is recommended to have fewer storage volumes with larger sizes rather than having a large number of storage volumes with small sizes. During recover, the time taken to mount these a few volumes decreases the time to recovery.
