VMware 3V0-21.23 Exam Dumps - Actual Questions Answers

Based on VMware vSphere 8.x Advanced documentation and standard IT architecture practices, the architect is designing a new VMware vSphere solution and must identify a business factor that will impact the design. A business factor is a high-level organizational or strategic consideration that influences the design, typically related to goals, policies, financial constraints, or contractual obligations, as opposed to technical or operational details.

Requirements Analysis:

Business factor: This refers to a non-technical, strategic element that shapes the vSphere design, such as corporate policies, financial agreements, or business objectives. It impacts decisions like security, compliance, licensing, or integration with existing strategies.

Provided information:

The company has worked with multiple VMware partners (historical vendor relationships).

The company has an internal security policy referenced in long-running contracts (compliance and security obligations).

The company has an Enterprise License Agreement (ELA) with VMware (licensing and cost structure).

The company has a multi-year cloud subscription agreement (cloud strategy alignment).

Evaluation of Options:

A. The company has previously worked with multiple VMware partners:

Why incorrect: While prior partnerships with VMware partners may influence vendor selection or implementation expertise, this is a historical operational detail, not a strategic business factor. It does not directly impact the design’s architecture, such as security, licensing, or workload placement, unless explicitly tied to ongoing obligations (not indicated here).

The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.

Creating a VM-Host Affinity rule ensures that specific workloads are restricted to certain hosts, which can be useful to avoid placing critical applications on hosts that may not meet their availability requirements.

The solution will enable vSphere High Availability (HA) with restart priority set to "Highest" for the application virtual machines.

Enabling vSphere HA ensures that virtual machines are automatically restarted on other hosts in the event of a host failure. Setting the restart priority to "Highest" for mission-critical VMs ensures that these VMs will have the highest priority for restart if any issues arise.

The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.

Enabling vSphere Fault Tolerance (FT) ensures that the application VMs are fully protected by creating a live shadow VM that runs in lockstep with the primary VM. In the event of a host failure, the shadow VM will take over instantly, providing continuous availability for the application.

The solution will create a virtual machine DRS group that contains all of the critical application workloads.

Creating a virtual machine DRS (Distributed Resource Scheduler) group for critical workloads ensures that these VMs are placed and migrated to the optimal hosts based on the cluster's resource requirements, improving availability and performance.

To meet the requirements outlined, the architect will need to design a solution with three VMware vCenter instances. Here's why:

Isolation of Virtual Infrastructure Management Operations: The management workloads (such as vCenter itself, along with other virtual infrastructure management tools) should be isolated from compute workloads. This suggests the need for a separate vCenter instance to manage the infrastructure without impacting compute workloads.

Physical Isolation of Production and Development Workloads: Production workloads and development workloads need to be physically isolated, which suggests the need for different vCenter instances to maintain separation.

Support for Operational Management in the Event of a Disaster: In the event of a disaster affecting the primary site, the secondary site should still be able to manage compute workloads. This could be achieved by having a vCenter instance in each site (primary and secondary) to ensure continued management in the event of a failure.

Breakdown of the three vCenter instances:

vCenter 1: Manages production workloads across both primary and secondary sites.

vCenter 2: Manages development workloads in the secondary site, ensuring isolation from production.

vCenter 3: Manages the virtual infrastructure management workloads, ensuring isolation from compute workloads.
