3V0-21.21 Advanced Design VMware vSphere 7.x Questions and Answers

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 designing a series of new vSphere environments for an organization. The environments will be deployed in their US-East and US-West region data centers. Each data center may have one or more dedicated vSphere environments. Only the vSphere environments within a data center will be configured with Enhanced Linked Mode. The Chief Technology Officer (CTO) has authorized the use of VMware vRealize Automation Cloud for automation. The build team creates standardized virtual machine images for various operating systems in Open Virtualization Format (OVF) and publishes the latest version on an as-needed basis to an internal HTTPS-accessible repository.

The architect must design a content library topology that meets the following requirements:

• A localized content library must be available in each data center.
• Each content library must be updated when an image is updated and released by the build team.
• The cloud automation platform must be able to consume the latest approved content library images.
• It must leverage the existing build team processes.

What should the architect recommend to meet the requirements?

An architect is designing a VMware solution for a customer to meet the following requirements:

• The solution must use investments in existing storage array that supports both block and file storage.
• The solution must support the ability to migrate workloads between hosts within a cluster.
• The solution must support resource management priorities.
• The solution must support the ability to connect virtual machines directly to LUNs.
• The solution should use existing 32G fabric infrastructure.
• There is no budget for additional physical hardware.

Which design decision should the architect make to meet these requirements?

An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:

• REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.
• REQ02 The infrastructure must initially run 100 virtual machines.
• REQ03 Ten of the virtual machines must be compliant with internal security standard.
• REQ04 The internal security standard specifies logical network separation for in-scope applications.
• CON01 The customer has already purchased the licenses as part of another project.
• CON02 The customer has five physical servers that must be reused.

Additionally, based on resource requirements, four physical servers will be enough to run all workloads. Which recommendation should the architect make to meet requirements while minimizing project costs?

An architect is tasked with designing a new VMware software-defined data center (SDDC) using VMware vSAN. The architect uses a storage assessment tool to determine the storage requirements for the new vSAN cluster. The new SDDC is going to be deployed into the existing data center and must be connected to a shared core network switch.

The architect decides to use vSAN ReadyNodes with the following configuration:

• Two disk groups with:

• uk.co.certification.simulator.questionpool.PList@195eb530

• Four 10 GbE ports

Which element represents a risk that should be included in this design?

An architect is designing an environment for a retail customer. The design will use a single small vCenter Server Appliance and a cluster of eight ESXi hosts at a remote site.

Virtual machine backups at the site will be dependent on the vCenter Server being available.

Which design decision should the architect make to maximize availability for backups?

An architect is designing a VMware solution for a customer based on the following information:

The procurement team purchases licensing and there is no further budget allocated.

Which design decision should the architect make to meet this requirement?

A architect is designing a new VMware software-designed data center (SDDC) using vSphere 7 to meet the following requirements:

• The SDDC must be deployed at two locations: primary and secondary.
• vSphere Replication must be used to replicate virtual machines between the two locations.
• Site Recovery Manager must be used to orchestrate disaster recovery (DR) activities.
• One single-sign on (SSO) domain must be used to authenticate access at both locations.

Which design decision should the architect make to meet these requirements?

A customer requests a review of its current vSphere platform design.

The following information is noted:

• There are three different workload profiles for the virtual machines:

• uk.co.certification.simulator.questionpool.PList@195e8a10

• Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster.
