Refer to the exhibit.

Your company is currently using a traditional SAN storage network. The server infrastructure is partially virtualized. There is a public cloud in place that is used to test development and application migration to cloud.
Business requirements:

- Simplify network management and storage provisioning
- Maintain application performance
- A disaster recovery plan to meet RTO / RPO targets
Other considerations:
- All data must be secured at rest and in-flight
- Include an app development platform
Refer to Case 6.
