3V0-21.21 Sample Questions & Answers

Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?

A customer has a database cluster with 40/60 read/write ratio and a high lOPs requirement with no contention on an all-flash vSAN cluster.

Which two storage settings should be configured for best performance? (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 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 designing a new vSphere environment to meet the following requirements:

• The environment must support 5,000 virtual machines.
• The environment will be built initially using 350 hosts.

Which vCenter Server appliance deployment size should the architect specify for the design?

An architect is designing a new vSphere platform for a customer to meet the following requirements:

• The platform must be deployed into five physically separate sites.
• The sites are spread across multiple regions.
• Some sites require more than one vCenter Server.
• The platform must provide an administrator with the ability to access virtual infrastructure components across all sites from a single management tool instance.

Which single sign-on (SSO) design recommendation will meet these requirements?

An architect is designing a vSphere environment for a customer based on the following information:

• The vSphere cluster will have three hosts only due to budget considerations.
• A database cluster (node majority) consisting of three virtual machines will be running on the vSphere cluster.

Which two recommendations can the architect make so that the customer achieves the highest level of application availability while taking into consideration operational resiliency? (Choose two.)
