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

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 organization's existing vSphere environments are configured for Enhanced Linked Mode. The DevOps team automates the creation of hardened virtual machine images for various operating systems. Their continuous integration/continuous delivery (CI/CD) pipeline runs a task at the end of a successful build, which uploads the Open Virtualization Format (OV) image to a sandbox content library, deploys a virtual machine from the image, and then destroys these objects after quality checks are complete.

The following requirements have been noted:

• All content libraries and images must be centrally created and managed.
• All images must be capable of being updated.
• All images must be refreshed and available to subscribed libraries within 24 hours.
• All images must provide details of the image contents and versions.
• All images must be capable of being reverted to a previous version.
• All images must be capable of having the hardware and guest operating system customized during deployment.

Which three recommendations should the architect make to design a content library solution that will meet these requirements? (Choose three.)

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:

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