Question 44

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.)

    Correct Answer: B, E

    It is assumed that the existing backup service has sufficient capacity for the new requirements, as it must handle all virtual machine backups. This is critical for meeting the RTO and RPO objectives. Additionally, the clusters having a minimum redundancy of N+1 is assumed to ensure that the availability target of 99.5% is met without affecting resource capacity during maintenance activities.

nemisis95Options: BE

B. The backup service has sufficient capacity for the new requirements "All virtual machine backups must be completed using the existing backup service." The existing backup service may not have capacity or compatabiltiy for the new SDDC E. The clusters will have a minimum redundancy of N+1 "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" We assume N+1 is sufficient. They may require a higher level of redundancy. A. The backup service will store data in a secure facility We assume this, no where is this documented C. The customer will update their hardware standard to support rack mount servers "standard document states that all virtual infrastructure hosts must be based on blade architecture only." D. All virtual machines will be deployed with the same resource profile for production and development "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."

B could not be a risk, either than assumption ??

estornudoOptions: BE

I'd say it is B and E

migonemati1414Options: BE

B and E as well

haditOptions: BE

Agree with B & E

rajeshrubOptions: BE

Yes. it shall be B & E. A is ruled out. No assumption can be made. C is ruled out since assumption is blade.

JailBreak

No, C is wrong. Because it says, "hosts must be based on blade architecture only." The customer doesn't say it is, it says it must be. So we need to assume that "The customer will update their hardware standard to support rack mount servers"

FR_WolfmanOptions: BD

I would say B & D A >> Making assumption that the backup service is securely stored will not impact or help the design. It can be excluded B >> We have to use the existing backup service, we have to assume it will have sufficient capacity C >> The hardware used is a constraint D >> As we don’t have details on the VMs configurations, we will have to make assumptions to help in sizing the infra E >> You cannot make such an assumption. It could be a constraint, if it was listed in the requirements.

I'd say it is B and C

VCIX_ChrisOptions: BE

B and E B - The topic "backup" is mentioned with RPO and RTO, so we can assume that there ist enough capacity to fulfill the requirements. E Availability should be 99,5%, so we can assume that at some point redundancy is needed.
