3V0-21.23 Exam Dumps - VMware Certification Questions and Answers

The design became constrained when the customer required the use of the corporate Active Directory Domain Services (AD DS) solution. The security team's intervention and insistence on using the corporate Active Directory effectively limited the options available for the authentication solution, as OpenLDAP was no longer a valid choice. At this point, the solution's scope was restricted to ensure compatibility with the customer's existing Active Directory infrastructure, which imposed a specific requirement on the design.

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.

Performance refers to the system’s ability to meet the required service levels under various conditions, including handling spikes in memory demand. In this case, the architect is ensuring that the cluster can handle memory spikes of up to 20% without contention, which is a key performance requirement to ensure that the workloads run optimally during peak business hours.

The ability to accommodate these memory demands without impacting performance directly aligns with ensuring that the system performs as expected under peak load conditions.

This solution aligns with the requirements of having a primary and secondary isolated environment, orchestration of application dependencies, the ability to scale on demand in a disaster recovery (DR) scenario, and a single interface for management. VMware Cloud on AWS integrates with VMware's vSphere environment and offers orchestration for DR, as well as the flexibility to scale resources on demand in the event of a DR scenario. It also provides a unified management interface through vCenter.

This is a business requirement because it aligns with corporate sustainability goals, focusing on reducing environmental impact. It is a high-level goal that can drive design decisions but is not directly related to the technical function or features of the system.

This is a technical (formerly non-functional) requirement because it specifies a particular feature (EVC mode for specific processor generations) that the infrastructure must support to ensure compatibility across the vSphere environment. This requirement addresses a technical aspect of how the environment will function but does not directly relate to business functionality.

The database must be backed up every day during the maintenance window of 1:00AM and 3:00AM.

This is a logical design requirement because it specifies the timing for the backup operations. It's important to define backup schedules to align with the maintenance window, ensuring minimal disruption to production workloads.

The database will be backed up using an API-based backup solution.

This is a logical design decision that specifies the method of backup. Using an API-based backup solution is a modern, efficient way to ensure consistent and application-aware backups of databases.

This strategy meets the requirements because:

Keeps data locally: By selecting a partner with a global data center presence, data can remain local to each specific location, meeting the geographical data residency requirement.

Quick scalability: The partner already has data centers in place, enabling the company to scale quickly and be functional within one month, which meets the timeline requirement.

Utilizes current processes: The existing processes around vSphere can still be leveraged since the partner can deploy compatible company architecture that aligns with the company's current infrastructure and processes.

VMware licensing costs: VMware licenses would be managed as part of the partnership arrangement, ensuring costs are aligned with the company's existing VMware infrastructure.

The storage hardware may not have capacity for future workload scale:

While the assumption is that the storage hardware has sufficient capacity for future workload scale, it’s important to acknowledge that there may be scenarios where the current storage capacity might not be sufficient. The architect must document this potential limitation as a risk to the design, ensuring that it is clear that the capacity assumption is not guaranteed.

Additional storage capacity can be procured to expand the solution in the future as needed:

This statement provides a mitigation strategy to address the assumption regarding storage capacity. If future scale requires more storage than initially provided, the design should include a strategy for procuring and integrating additional storage resources to meet demand as needed. This helps ensure scalability and adaptability in the future.
