An architect is finalizing the design for a new vSphere platform based on the following information:

All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes.

All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes.

During a requirements gathering workshop, the customer's Chief Information Security Office (CISO)

provides the following requirements that are pertinent to the design of a new vSphere environment:

Which requirement classification is being gathered for the design documentation?

A. Security

B. Manageability

C. Recoverability

D. Availability

Following a recent acquisition, an architect needs to merge IT assets into its current data center. The

combined vSphere environment will need to run the newly acquired company's virtual machines.

Network integration work has already been completed and the current environment has capacity to host all

virtual machines. The Operations team needs to identify which virtual machines belong to the acquired

company and report on their usage.

How should the architect merge the company's assets and virtual machines?

A. Leave the newly acquired company's assets in its current place

B. Lift and shift the acquired assets into the data center

C. Migrate the acquired company's virtual machines into the existing vSphere environment

D. Migrate and apply vSphere tags to the acquired company's virtual machines

In a meeting to discuss the minimum viable product (MVP) deployment of a new customer-facing application, the key stakeholder shares details of the application components and the application administrators share details of performance and integrity tests for the application.

The application will be made up of the following components: A web server

-

Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online. An application server

-

Steps to confirm application server integrity will take 15 minutes after the database is online. A database server

-The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to restore and validate database services within one hour.

The existing VMware infrastructure offers a recovery point objective (RPO) of 5 minutes and recovery time objective (RTO) of 15 minutes through a combination of backups and replication.

C. 105 minutes

D. 90 minutes

C. The solution must use a vRealize Orchestrator workflow for VM placement

D. The solution must use VM-Host affinity rules

E. The solution must use vSphere VM and host DRS groups

Refer to the exhibit.
