[All 3V0-21.23 Questions]

An architect is designing a new vSphere-based solution for a customer.

During a requirement gathering workshop, the following information is provided:

The solution must have a primary and secondary site.

The solution must support a maximum of 1,000 concurrent workloads.

The profile of the workloads are as follows:

- Production Workloads

-- 300 x Small: 1 vCPU, 2GB RAM

-- 400 x Medium: 2 vCPU, 6GB RAM

-- 100 x Large: 4 vCPU, 8GB RAM

- Development Workloads

-- 200 x Small: 1 vCPU, 2GB RAM

The corporate security policy states that, during normal operations, production workloads must be physically segregated from development workloads.

All production workloads are split evenly across the primary and secondary site.

All development workloads run only within the secondary site.

In the event of a disaster affecting workloads in the primary site, the secondary site must be capable of running all production and development workloads.

The vCPU to physical core ratio should be a maximum of 10:1 for production workloads and 20:1 for development workloads.

The solution should provide a minimum of N + 1 resiliency at each component level.

The target physical host hardware platform has already been defined by the company's hardware standards and therefore each host has the following configuration:

-- 2 x 24 physical cores

-- 768GB RAM

-- 2 x 100GB SSD drives

-- 6 x 10GbE network cards

What is the minimum number of hosts required to meet the requirements?

A12

B14

D10

Show Suggested Answer

Suggested Answer: A

1. Production Workloads:

Total vCPUs required for production:

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

2. Development Workloads:

Total vCPUs required for development:

3. Workload Distribution:

4. vCPU to Physical Core Ratio:

5. Hosts Configuration:

6. Host Calculation:

Production Workloads (750 vCPUs per site):

Development Workloads (200 vCPUs):

7. Resiliency:

8. Total Hosts:

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

12 hosts sounds reasonable considering the workload distribution.

Wait, all production workloads split evenly? That's a lot to manage!

Looks like we need to calculate the total vCPUs and RAM first.

I feel like we might need to do some calculations for the total RAM and vCPUs required first before deciding on the number of hosts.

The requirement for N + 1 resiliency is crucial, but I’m a bit confused about how that impacts the total number of hosts we need.

I think we need to consider the vCPU to physical core ratio for production workloads, which is 10:1. That might help narrow down the options.

I remember we practiced a similar question about workload distribution, but I’m not sure how to calculate the exact number of hosts needed here.

This is a tricky one. I'll need to be really careful in my calculations to ensure I don't miss any of the requirements or make any mistakes. I'll start by mapping out the workload details and then work through the host configuration to find the optimal solution.

Okay, I think I've got a handle on this. The key is to first calculate the total resource requirements for the production and development workloads, then determine the minimum number of hosts needed to meet those requirements while adhering to the stated policies and constraints. I'm confident I can work this out.

Hmm, I'm a bit unsure about how to approach this. There are a lot of specific details and constraints to consider, like the physical host hardware, vCPU to core ratios, and resiliency requirements. I'll need to take my time and work through it step-by-step.

This looks like a complex question that requires careful planning and calculations. I'll need to review the requirements closely and break down the workload details to determine the optimal host configuration.

I'm with Elvera on this one. The math seems to add up for 14 hosts, and the requirements are pretty clear. Definitely B) 14.

C) 8 hosts? That seems way too low, even for a vSphere solution. These requirements are pretty complex, so I'd be surprised if that's the correct answer.

I agree with Lindsay, the rationale is that we need to calculate the total number of vCPUs required for production and development workloads and then divide by the vCPU to physical core ratio.
