VMware 3V0-21.23 Practice Test Questions Answers

This is the business objective that translates to a conceptual model constraint, as it is an external requirement that must be met by the system design, influencing how the architecture should be shaped. Compliance audits often dictate specific standards, security, and operational procedures that must be adhered to, which restricts the design choices in terms of governance and best practices.

1. Production Workloads:

300 x Small: 1 vCPU, 2 GB RAM

400 x Medium: 2 vCPU, 6 GB RAM

100 x Large: 4 vCPU, 8 GB RAM

TotalvCPUsrequired for production:

Small: 300 x 1 = 300 vCPUs

Medium: 400 x 2 = 800 vCPUs

Large: 100 x 4 = 400 vCPUs

Total production vCPUs= 300 + 800 + 400 =1,500 vCPUs

2. Development Workloads:

200 x Small: 1 vCPU, 2 GB RAM

Total vCPUsrequired for development:

Small: 200 x 1 =200 vCPUs

3. Workload Distribution:

Production workloads are split evenly across the primary and secondary site:750 vCPUs per site(1,500/2).

All development workloads run in the secondary site:200 vCPUs.

4. vCPU to Physical Core Ratio:

Production workloads:10:1 ratio(vCPU to core ratio).

Development workloads:20:1 ratio(vCPU to core ratio).

5. Hosts Configuration:

Each host has24 physical coresand768 GB of RAM.

Since the maximum vCPU-to-core ratio for production is 10:1, each host can support240 vCPUs(24 cores x 10).

For development, with a ratio of 20:1, each host can support480 vCPUs(24 cores x 20).

6. Host Calculation:

Production Workloads(750 vCPUs per site):

750 vCPUs for production divided by 240 vCPUs per host =3.125 hosts(rounding up =4 hostsper site for production).

Development Workloads(200 vCPUs):

200 vCPUs divided by 480 vCPUs per host =0.416 hosts(rounding up =1 hostfor development).

7. Resiliency:

N + 1 resiliencymeans we need one extra host per site to provide redundancy.

8. Total Hosts:

4 hostsfor production in the primary site.

4 hostsfor production in the secondary site.

1 hostfor development in the secondary site.

1 additional hostfor N + 1 resiliency in both sites.

Total hosts required= 4 (primary production) + 4 (secondary production) + 1 (secondary development) + 2 (N + 1) =12 hosts.

The customer has outlined the following requirements:

Automated deployment and lifecycle management of the vSphere platform: This requires a solution that provides automated provisioning, management, and updates. VMware Cloud Foundation (VCF) is an integrated platform that provides automation for the lifecycle of the vSphere platform, including updates and patch management.

Self-Service deployment of virtual machines and other objects from a central catalog: VMware Cloud Foundation includes tools like vRealize Automation (part of VCF) that enable self-service provisioning of virtual machines and other resources. Additionally, VCF provides centralized management for provisioning and orchestration.

Monitoring, logging, and analytic tooling for visibility and troubleshooting: VMware Cloud Foundation integrates with vRealize Operations and vRealize Log Insight, which provides visibility, monitoring, and logging capabilities for the entire solution. These tools help in analytics and troubleshooting across the entire infrastructure.

Support deployment via infrastructure-as-code methods for additional management components: VMware Validated Solutions (such as vRealize Automation or vRealize Orchestrator) provide infrastructure-as-code capabilities, ensuring that the solution can be deployed in a consistent, repeatable manner, automating deployments of not just vSphere but also additional management components.

Cost-effectiveness with a fast time to value: VMware Cloud Foundation offers an integrated solution that is pre-configured and validated, which speeds up deployment and reduces operational complexity. By using VMware Validated Solutions for additional management components, the customer can leverage existing, tested solutions that are optimized for use with VCF, ensuring cost-effectiveness while meeting requirements.

Performance design quality refers to ensuring that the system can handle the expected load and operate efficiently under varying conditions. This includes the ability to handle spikes in demand, such as CPU usage, without degradation in service. The statement "The solution must scale to meet spikes in CPU demand" addresses how the system will handle sudden increases in workload, ensuring that the solution meets performance expectations even under peak conditions.

VMware vCenter instance in each management domain for the virtual infrastructure management of management workloads:

The customer requiresisolation between management and compute workloads. By deployingvCenter instances in dedicated management domains, the management workloads can be handled separately from production and development compute workloads, ensuring isolation.

VMware vCenter instance in the secondary site management domain for the virtual infrastructure management of production compute workloads:

Thesecondary siteshould also have avCenter instancefor the management ofproduction compute workloads. This ensures thatoperational managementof production workloads is still possible even in the event of adisaster affecting the primary site, which aligns with the requirement to ensure themanagement of compute workloads in the secondary site.

VMware vCenter instance in the primary site management domain for the virtual infrastructure management of production compute workloads:

AvCenter instancein theprimary site management domainshould handle themanagement of production compute workloads. The primary site is typically where most production workloads reside, and having the vCenter instance here ensures that management operations can be performed efficiently.

Separate management domain within each site for hosting local management workloads:

To ensure thatmanagement operations are isolatedand that themanagement workloads do not affect compute workloads, aseparate management domainshould be deployed in each site. This ensures that the management functions do not consume compute resources that are intended for production or development workloads.
