3V0-21.21 Exam Dumps : Advanced Design VMware vSphere 7.x

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?

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 support the concurrent running of 1,000 virtual machines
• The production environment must be delivered across two geographically dispersed data centers All virtual machines must be capable of running in either data center.
• The two data centers are currently connected to each other through a single but diversely routed, high bandwidth and low latency link.
• The link between the two data centers is capable of supporting a round-trip time (RTT) of 150 ms The existing server hardware standard document states that all virtual infrastructure hosts must be deployed using vSAN ReadyNodes
• The service owner has stated that it is critical to ensure the availability target of 99.9% All virtual machine backups must be completed using the existing backup service
• The recovery time objective (RTO) for the service is five minutes
• The recovery point objective (RPO) of the service is four hours

Which two elements represent risks to the successful delivery of this solution? (Choose two.)

An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.

The platform has recently commissioned new hosts to update the development cluster.

The development cluster host configuration is:

• 4 ESXi hosts with 2 sockets × 16 cores
• 512 GB RAM divided evenly between sockets
• There is no resource contention

The benchmarking cluster host configuration is:

• 8 ESXi hosts with 2 sockets × 8 cores
• 256 GB RAM divided evenly between sockets
• There is no resource contention

The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.

What is a possible reason for the difference in performance test results between the development and benchmarking clusters?
