At ValidExamDumps, we consistently monitor updates to the VMware 3V0-21.21 exam questions by VMware. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the VMware Advanced Design VMware vSphere 7.x exam on their first attempt without needing additional materials or study guides.

Other certification materials providers often include outdated or removed questions by VMware in their VMware 3V0-21.21 exam. These outdated questions lead to customers failing their VMware Advanced Design VMware vSphere 7.x exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the VMware 3V0-21.21 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.

 

Question No. 1

During a requirements gathering workshop, the customer provides the following requirement:

A new vSphere platform must be designed securely and all interfaces must be protected against potential snooping.

How should this non-functional security requirement be documented?

Question No. 2

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.)

Show Answer Hide Answer
Correct Answer: B, E

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.


Question No. 3

A architect is designing a new VMware software-designed data center (SDDC) using vSphere 7 to meet the following requirements:

The SDDC must be deployed at two locations: primary and secondary.

vSphere Replication must be used to replicate virtual machines between the two locations.

Site Recovery Manager must be used to orchestrate disaster recovery (DR) activities.

One single-sign on (SSO) domain must be used to authenticate access at both locations.

Which design decision should the architect make to meet these requirements?

Correct Answer: C

'One single-sign on (SSO) domain must be used to authenticate access at both locations.' Install vCenter at Primary site, create SSO Domain. Install vCenter at Secondary site, join to SSO Domain.


Question No. 4

A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.

What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?

Show Answer Hide Answer
Correct Answer: A

cluster must be able to maintain N+1

current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.

So, we need 3 hosts to support N+1.

Customer wants to be able to patch and update two hosts in parallel.

So that means 5 hosts are required.


Question No. 5

Which two of the listed requirements would be classified as manageability non-functional requirements? (Choose two.)
