All virtual machines operate supported versions of Microsoft Windows All virtual machines have VMware Tools 11 or higher installed vCenter Enhanced Linked Mode is configured VMware PowerCLI is available in the environment No budget is available for discovery tooling

The architect must capture and review active services from inside running virtual machines to inform the migration design.

Considering the information available, which method can the architect use to acquire the information required?

25. An architect is designing a new vSphere solution. The following information has been gathered during the design workshops with the customer:

The solution will be deployed into two availability zones (AZs)

The solution will be configured as a single stretched cluster with shared storage across the two AZs Production and Development workloads will run across both AZs The cluster is configured as N + 1

The architect needs to ensure that, in the event of a host failure during maintenance of another host in the cluster, only the Production workloads are recovered.

- 10 servers that contain 2 x 24-Core Intel Xeon processors and 768 GB RAM from Vendor A

- 20 servers that contain 2 x 16-Core AMD EPYC processors and 512 GB RAM from Vendor B

- 10 servers that contain 1 x 24-Core AMD EPYC processors and 256 GB RAM from Vendor B All of the hardware is currently listed on the VMware Hardware Compatibility List (HCL).

All existing server hardware has 36 months vendor support remaining.

The customer has provided the architect with the following information about the workloads:

Critical workloads have a WRT of 12 hours

Production workloads have a WRT of 24 hours

Development workloads have a WRT of 24 hours

All workloads have an RPO of 4 hours

Critical workloads have an RTO of 1 hour

Production workloads have an RTO of 12 hours

Development workloads have an RTO of 24 hours

The customer has also confirmed that the Disaster Recovery solution will not begin the recovery of the development workloads until all critical and production workloads have been recovered at the secondary site.

What would the architect document as the maximum tolerable downtime (MTD) for each type of workload in the design?
