Top Tips Of Update 3V0-21.21 Practice Exam

NEW QUESTION 1
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.)

• A. The backup service will store data in a secure facility
• B. The backup service has sufficient capacity for the new requirements
• C. The customer will update their hardware standard to support rack mount servers
• D. All virtual machines will be deployed with the same resource profile for production and development
• E. The clusters will have a minimum redundancy of N+1
