An architect is designing a new vSphere environment to meet the following requirements:
- REQ01 The platform must provide a minimum of N+1 redundancy.
- REQ02 The recovery point objective (RPO) for all virtual machines within the environment is one hour.
- REQ03 The production environment must be deployed into the primary data center.
- REQ04 The design must adhere to the company security standards, which include Payment Card Industry (PCI) Data Security Standard compliance.
- REQ05 The platform must be capable of running 1,000 virtual machines across both data centers concurrently.
Which two of the listed requirements would be classified as functional requirements? (Choose two.)

An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.
During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:
- The solution must initially support the concurrent running of 300 production and 600 development virtual machines.
- The production environment should be delivered across two geographically dispersed data centers.
The development environment must be vSphere-based but does not have to be deployed on-premises.
- The two data centers are connected to each other through multiple diversely routed, high bandwidth and low latency links.
- The customer's server hardware standard document states that all virtual infrastructure hosts must be based on blade architecture only.
- The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities, such as the monthly software patching and ad-hoc hardware break/fix.
- All virtual machine backups must be completed using the existing backup service.
- The recovery time objective (RTO) for the service is four hours.
- The recovery point objective (RPO) of the service is 24 hours.
Given the information from the customer, which two would be classified as assumptions within the design? (Choose two.)

An architect is designing the expansion of an existing vSphere 7 environment. The customer is requesting a design for a new cluster to support the anticipated future business growth. The requirements specified for the existing environment design must be considered when designing the new cluster.
The existing design has the following requirements:
- REQ01 The environment has an availability target of 99.5% for all infrastructure.
- REQ02 The recovery time objective (RTO) for Tier 1 virtual machines is one hour.
- REQ03 Windows and Linux virtual machines must reside on separate clusters.
- REQ04 Access to the management cluster within the environment must be controlled.
Which of the listed requirements would be classified as a functional requirement?
