3V0-21.21 Exam Dumps : Advanced Design VMware vSphere 7.x

An architect is tasked with designing a new VMware software-defined data center (SDDC) solution for an online retail customer who has a primary and secondary data center as well as 10 distribution hubs.

The customer has provided the following business requirements to help inform the design:

• The solution must support the running of up to 1,000 concurrent virtual machines across the primary and secondary data center.
• The solution must support the running of up to 20 concurrent virtual machines in each distribution hub.
• The solution must support the separation of management and lines-of-business application virtual machines.
• All management components (including directory services, backup, automation, operations and logging) must be deployed to the primary data center.
• All virtual infrastructure components must have redundancy of N+1.
• All sites are connected to each other using a wide area network that has multiple diversely routed links.
• The solution should support a monthly uptime target of 99.9%.
• The recovery time objective (RTO) for the solution must be four hours.
• The recovery point objective (RPO) for the solution must be 24 hours.

Given the information from the customer, which assumption should the architect include in the design?

An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.

The platform has recently commissioned new hosts to update the development cluster.

The development cluster host configuration is:

• 4 ESXi hosts with 2 sockets × 16 cores
• 512 GB RAM divided evenly between sockets
• There is no resource contention

The benchmarking cluster host configuration is:

• 8 ESXi hosts with 2 sockets × 8 cores
• 256 GB RAM divided evenly between sockets
• There is no resource contention

The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.

What is a possible reason for the difference in performance test results between the development and benchmarking clusters?

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.)
