Question 1

An architect is documenting the design for a new vSphere cluster. The customer provides the following information:

All ESXi hosts will use hardware from the same vendor

All ESXi hosts will be monitored for hardware related issues using the vendor's monitoring tooling

The vendor's monitoring tooling provides a plugin for vCenter to allow the hardware status to be visible

The customer also informs the architect of the following requirements:

Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded.

Workloads must be automatically restarted on other hosts in the event of a host failure.

What should the architect include in the design to meet these requirements?



Answer : D

To meet the customer requirements, we need to address the two specific scenarios:

Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded:

This requirement can be fulfilled by Proactive HA. Proactive HA is a feature of vSphere HA that works in conjunction with hardware health monitoring tools, such as the vendor's plugin for vCenter. When the vendor's monitoring tool marks a host as degraded (due to hardware issues), Proactive HA can automatically trigger the migration of workloads to other hosts, based on the Automation Level configuration.

Workloads must be automatically restarted on other hosts in the event of a host failure:

This can be managed using vSphere HA with the setting to restart VMs when a host fails. This ensures that in the event of a host failure, workloads are automatically restarted on available hosts in the cluster.

By enabling Proactive HA with an Automation Level of Automated, the architect ensures that degraded hosts are automatically handled (through workload migration) without manual intervention.


Question 2

An architect is designing a solution for a customer to meet the following business objectives:

Pass compliance audits

Reuse compute hardware

Grow by 10% per year

Move to a subscription-based consumption model

Which business objective translates as a conceptual model constraint?



Answer : A

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.


Question 3

An architect is working on a new VMware vSphere design and notes the following information during interviews with stakeholders:

The company has previously worked with multiple VMware partners

The company has an internal security policy that is referenced in long running contracts

The company has an Enterprise License Agreement (ELA) with VMware

The company has a multi-year cloud subscription agreement

Which of these is a business factor that will impact this design?



Answer : B

The Enterprise License Agreement (ELA) is a business factor that will impact the design because it defines the licensing structure, which directly influences the solution's cost, scalability, and use of VMware products. The ELA could provide benefits such as discounted licensing costs, a predefined set of VMware products, or specific terms and conditions that must be adhered to in the design.


Question 4

An architect is designing the datastore configuration of a new vSphere-based solution.

The following information was obtained during the initial meeting with the customer:

There is currently 500 production and DMZ virtual machine workloads spread evenly across the primary and secondary site.

The profile of the workloads (per site) is as follows:

- DMZ:

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

- Production:

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

-- 100 x Medium: 2 vCPU, 4 GB RAM, 200GB disk

-- 25 x Large: 4 vCPU, 8 GB RAM, 500GB disk

The average IO Profile per workload is 70/30 read/write.

The solution should cater to 10% storage growth in the first year.

The solution should cater to 15% virtual machine snapshot overhead.

The storage team has confirmed:

- A scalable external storage array has been deployed per site to support the storage requirements.

- The storage array will connect to all hosts using a dedicated Fibre Channel storage area network fabric.

- Usable storage capacity is available in 10TB LUNs.

- As many LUNs as required can be provided.

- Every effort should be made to ensure the number of required LUNs is minimized.

The security team has stated that all DMZ and production workloads must remain logically isolated from each other.

Given the information provided, which three design decisions should the architect make to meet the requirements? (Choose three.)



Answer : A, C, D

Six 10TB VMFS datastores will be configured on each site for all production workloads.

This choice is based on the need to distribute production workloads across multiple datastores while ensuring that each datastore is large enough to accommodate the space required by the workloads. Given the average sizes of the virtual machines and the growth and snapshot overhead, six 10TB VMFS datastores would be appropriate for production workloads, ensuring scalability while minimizing the number of LUNs.

Each 10TB LUN will be configured as a VMFS datastore.

VMFS (Virtual Machine File System) is the standard choice for vSphere environments when using Fibre Channel LUNs. It provides the necessary features, such as concurrency and high-performance access, for production workloads. This option is appropriate given that the storage array uses Fibre Channel for connection and VMFS is the standard file system for such configurations.

Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.

The DMZ workloads are smaller in number and storage requirements compared to the production workloads, so configuring two 10TB VMFS datastores for DMZ workloads will provide enough capacity while maintaining logical isolation. This approach also minimizes the number of LUNs required to meet the storage growth needs.


Question 5

As part of designing a greenfield vSphere-based hosting solution, an architect is responsible for defining a patch management solution for the virtual infrastructure.

During initial meetings with the customer, the following information is provided:

There are two geographically dispersed physical sites (primary and secondary) in scope for the solution.

The inter-site connectivity has been classified as low bandwidth and high latency.

The customer has the following requirements:

REQ001 - Only IT Security Team-approved versions of VMware Tools should be installed across all workloads within the infrastructure.

REQ002 - The solution should minimize traffic across the inter-site link.

REQ003 - Upgrades to the virtual infrastructure should continue in the event of a failure with either site.

A combination of which three design decisions could the architect make to ensure the requirements are met? (Choose three.)



Answer : B, D, E

The solution will ensure that all VMware ESXi hosts within a site have access to the local VMFS datastore containing the shared VMware Tools repository.

This decision ensures that each site has local access to the VMware Tools repository, which minimizes traffic across the low-bandwidth, high-latency inter-site link. By keeping the repository within each site, the local ESXi hosts can access the repository without needing to traverse the inter-site link frequently.

The solution will set the UserVars.ProductLockerLocation advanced system setting on each VMware ESXi host to point to the local site shared repository.

This ensures that each ESXi host points to the local site repository for VMware Tools. This approach minimizes inter-site traffic by ensuring that all updates and patches are performed using local resources, avoiding the need to transfer VMware Tools files over the low-bandwidth, high-latency connection.

The solution will create a shared repository on a VMFS datastore within each site that contains all approved versions of VMware Tools.

This decision ensures that both sites have a local copy of the approved VMware Tools versions, in line with REQ001, which mandates that only IT Security Team-approved versions of VMware Tools should be installed. Additionally, it minimizes inter-site traffic, as both sites will use their local repositories.


Question 6

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?



Answer : A

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.


Question 7

A company is expanding and will be deploying new vSphere environments in multiple new locations. All environments use datastores backed by multiple storage technologies and vendors.

How can the architect create a design to efficiently and repeatedly distribute existing company virtual machine (VM) templates to multiple new locations?



Answer : C

This option allows for a centralized repository of VM templates that can be efficiently and repeatedly distributed to multiple locations. By creating a published content library, you enable the new locations to subscribe to this library, ensuring that the templates are synchronized and easily accessible. This approach minimizes manual effort and ensures consistency across all sites.
