3V0-21.21 Practice Exam Questions and Answers

An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC).

During the discovery phase, the following information is documented:

Cluster One

• Six ESXi hosts
• vSphere HA with host failures cluster tolerates = 1
• Proactive HA is enabled and set to automated
• Fully Automated vSphere DRS
• Transparent Page Sharing (TPS) is enabled

Cluster Two

• Eight ESXi hosts
• vSphere HA with host failures cluster tolerates = 1
• Proactive HA is disabled
• Partially Automated vSphere DRS
• Transparent Page Sharing (TPS) is disabled

Cluster Three

• Three ESXi hosts
• vSphere HA with admission control is disabled
• Proactive HA is not supported
• Transparent Page Sharing (TPS) is disabled

Virtual Machine Resource Profile 1

• Memory sharing techniques should not be used
• Virtual machines should be automatically restarted in the event of host failure if resources are available
• Automated initial virtual machine placement

Virtual Machine Resource Profile 2

• Memory sharing techniques should not be used
• Virtual machines should be automatically restarted in the event of host failure regardless of available resources
• Automated initial virtual machine placement

Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)

An architect is reviewing a physical storage design. The customer has specified that storage DRS will be used for ease of operational management for capacity and performance.

Which recommendation should the architect include in the design?

An architect is finalizing the design for a new vCenter Server High Availability deployment.

What is one thing the architect must document in the design?

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?

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

There is a request for approved virtual machine applications through a new vSphere platform’s integrated automation portal. The platform was built following all provided company security guidelines and has been assessed against Sarbanes-Oxley Act of 2002 (SOX) regulations.

The platform has the following characteristics:

• vRealize Operations is being used to monitor all clusters.
• There is a dedicated ESXi cluster, supporting all management services.

There is a dedicated ESXi cluster for all line-of-business applications.

• Network traffic is serviced by NSX-T.

There is a dedicated ESXi cluster for virtual desktop infrastructure (VDI).

• Network traffic is serviced by NSX-T.

The application owner is requesting approval to install a new service that must be protected as per the Payment Card Industry (PCI) Data Security Standard.

Which additional non-functional requirement should the architect include in the design to support the new service?

An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.

An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.

In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)

A customer has a database cluster with 40/60 read/write ratio and a high IOPs 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 creating a network design for a new vSphere environment.

Based on customer requirements, the environment must support the following types of traffic:

• Management
• vMotion
• vSAN
• Fault Tolerance
• Virtual machine traffic, which cannot be impacted by other types of traffic

Which design recommendation can the architect make for a resilient infrastructure with vSphere network service tiering?

A customer provides the following list of requirements for their vSphere platform:

• REQ01 The solution should utilize dual network connections to eliminate single points of failure.
• REQ02 The solution should allow logs to be retained for a period of 30 days.
• REQ03 All user access to the platform should be recorded for audit purposes.
• REQ04 The solution should allow the management of multiple ESXi hosts.
• REQ05 The solution should allow users to view the remote console of virtual machines.

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