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

What is a benefit of using a scale-out method for handling vSphere cluster growth?

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 designing a new backup solution for a vSphere platform that has been recently upgraded to vSphere 7.

The architect wants the backup solution to perform the following:

• Full virtual machine image backup and restore
• Incremental virtual machine image backup and restore
• File level backup and restore within both Windows and Linux virtual machines
• LAN-free backup

Which functional requirement should the architect include in the design of the new backup solution?
