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?
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.
An architect is designing a new vSphere 8 environment and needs to plan the migration of virtual machines from the source vSphere 7 infrastructure.
The following has been captured about the source infrastructure and project:
All virtual machines operate supported versions of Microsoft Windows
All virtual machines have VMware Tools 11 or higher installed
vCenter Enhanced Linked Mode is configured
VMware PowerCLI is available in the environment
No budget is available for discovery tooling
The architect must capture and review active services from inside running virtual machines to inform the migration design.
Considering the information available, which method can the architect use to acquire the information required?
Given that VMware Tools 11 or higher is installed on all virtual machines and VMware PowerCLI is available in the environment, the architect can leverage PowerCLI to interact with VMware Tools and collect information about active services running inside the virtual machines.
VMware PowerCLI allows you to query virtual machines for information about their services by accessing the guest operating system, provided VMware Tools is installed and running. You can use PowerCLI cmdlets to retrieve service data, such as which services are running on the VM, their statuses, and other details necessary for planning the migration.
This option is cost-effective since there is no budget available for additional discovery tooling, and it aligns well with the existing tools and infrastructure already in place.
What is an example of an availability design quality?
Availability design quality refers to the capacity of a system or infrastructure to remain operational, minimizing downtime, and ensuring continuous service delivery, especially in the event of a failure. The concept of N + 1 redundancy ensures that if one component fails (such as a host or a power supply), there is always an additional, spare component available to take over the workload, maintaining the system's availability.
N + 1 redundancy in a vSphere cluster means that the cluster has enough resources to tolerate the failure of one host without affecting the availability of the workloads. This setup provides high availability and resilience in the event of a host failure.
During a workshop for a design project, the following information is shared:
Develop and maintain strong relationships with key stakeholders and partners to promote collaboration.
Maintain high standards of quality and professionalism in all aspects of the project.
Build a strong foundation for future projects, including cloud infrastructures.
Ensure project timelines and milestones are met by effectively managing resources and priorities.
Which of these would be classified as a business outcome of the project?
A business outcome refers to a result or impact that directly contributes to the strategic goals of the organization, typically focusing on long-term objectives or future benefits. In this case, building a strong foundation for future projects, including cloud infrastructures, aligns with the business goal of positioning the organization for future success and scalability. This outcome is about preparing the organization for the future, which is a key business-driven result.
An architect is tasked with creating a design for a vSphere-based solution.
Reviewing requirements with the security team, the architect makes the following design decision:
ESXi hosts in the environment will enable shell sandbox for SSH connections and the local ESXi shell
What is an implication of the design decision to enable shell sandboxing?
When the shell sandbox is enabled on ESXi hosts, it restricts the execution of commands within the shell to ensure that only authorized or safe commands are allowed. This provides a level of isolation that limits the potential for accidental or malicious commands to be run in the shell, enhancing security while still providing necessary administrative access.
