Question 1

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?

Accepted Answer

A

Explanation: 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 2

An architect is discussing recoverability considerations for a new vSphere solution as part of a
requirements workshop. The customer has informed the architect that the company policy is to not
perform backups of ESXi hosts due to their selected backup software not supporting the ESXi
software. In the past, when hosts have experienced failures, the hosts have been reinstalled from the
VMware provided ESXi image and manually configured by an administrator. The customer asks the
architect to design a solution that will reduce the manual effort required by the administrator to
return a failed host to service.
What could the architect include in the design to meet the customer's request?

Accepted Answer

B

Explanation: A Host Profile in vSphere allows for standardized host configurations across a cluster. Once a profile is created and configured for a cluster, it can be applied to any host in that cluster, ensuring that the configuration is consistent and easily replicated. In case of a host failure, the failed host can be reinstalled from the VMware ESXi image, and the Host Profile can be applied automatically to bring the host back to the desired configuration. This reduces the manual steps required for host recovery, as the configuration will be automatically applied to the reinstalled host.

Question 3

The following is a list of requirements from a discovery workshop for a new VMware hosting platform
system design:
REQ001 - The architecture must support recoverability to the VMware Cloud Disaster Recovery
(VCDR) service.
REQ002 - The architecture must support high availability (HA) and fault tolerance (FT).
REQ003 - The architecture must support reducing existing energy consumption and carbon footprint.
REQ004 - The architecture must provide support for network virtualization using distributed virtual
switches.
Which requirement would be classified as a business (formerly functional) requirement?

Accepted Answer

B

Explanation: 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.

Question 4

An architect is tasked with designing a repeatable edge hosting solution using VMware technologies
that can be deployed to existing hotels across the world and operate independently of other
locations.
During interviews with stakeholders, the architect notes the following information:
There are 123 hotels in total.
All hotels have a minimum of two 1 Gbps connections for guest Internet access.
The company operates hotels in four countries: Canada, USA, Cuba and Mexico.
The company is rebranding the hotels located in Mexico.
Which of these is a business factor that will impact this design?

Accepted Answer

A

Explanation: This is a business factor that will impact the design because rebranding the hotels in Mexico could lead to changes in the company's requirements, such as the need for new branding, updated infrastructure, or integration of new services. These factors will influence the design decisions related to the edge hosting solution, potentially requiring special configurations or considerations for these locations.

Question 5

An architect is working on the cluster layout design for a new vSphere solution. The resource
requirements for the first cluster state that memory demand can experience spikes of up to 20% over
the documented average demand during peak business hours and the cluster must be able to handle
these spikes without contention.
Which design quality is being referenced?

Accepted Answer

B

Explanation: 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.

Question 6

What are two valid use cases for VMware Cloud Foundation remote clusters? (Choose two.)

Accepted Answer

B, C

Explanation: Enable vSphere with Tanzu on a cluster deployed at a remote location. VMware Cloud Foundation remote clusters can be deployed to extend the functionality of vSphere with Tanzu to remote locations. This allows for containerized workloads to be managed and orchestrated using the same tools as the primary environment, providing consistent management of Tanzu clusters across multiple sites. Provide resources for virtual machines at an edge location. Remote clusters can be deployed at edge locations to provide computing resources for workloads that need to run close to the data source. This use case is particularly useful for applications that require low latency or need to process data locally before sending it to the central cloud infrastructure.

Question 7

An architect is working with stakeholders to define requirements for architecting a new VMware
vSphere design.
What are two strategies for engaging with stakeholders to achieve this goal? (Choose two.)

Accepted Answer

C, D

Explanation: The architect conducts workshops with stakeholders to gather business and technical requirements. Workshops provide a collaborative environment where the architect can interact with key stakeholders to gather both business and technical requirements. This approach helps ensure that the final design aligns with the goals and needs of the business while considering the technical constraints and capabilities. The architect conducts multiple rounds of interviews with stakeholders, iteratively refining requirements. Multiple rounds of interviews allow the architect to gather input over time, refining the requirements and addressing any evolving needs. This iterative approach ensures that the solution meets the stakeholders' expectations and adapts as new information emerges.

Question 8

An architect is designing an upgrade to an existing vSphere environment. The project has been
created to provide options for enabling growth and scalability, without increasing the data center
footprint. The CIO has also tasked the architect with updating data protection operations, from the
current agent-based backup approach.
During a workshop with key stakeholders, the following information has been noted:
The existing vSphere environment uses an external fibre attached storage array for the vSphere
environment
The storage array is connected via 4 Gbps fibre cards host bus adaptors (HBAs)
The storage array does not support VMware Storage APIs—Data Protection (VADP)
The architecture must support scaling virtual machines CPU, memory, and storage
The environment will grow by an additional 20% virtual machines year over year
Only two additional racks of equipment can be provisioned
Which design choice will meet these requirements?

Accepted Answer

C

Explanation: This option aligns with the requirements for growth, scalability, and updating data protection operations. Using vSAN (Virtual SAN) Ready Nodes provides a hyper-converged infrastructure that combines storage and compute resources into a single platform, making it easy to scale both compute and storage without increasing the data center footprint. It also eliminates the need for traditional external storage arrays and allows for better data protection capabilities compared to the agent-based approach.

Question 9

An architect is designing a backup solution. Which two statements should be included in the logical design for this solution? (Choose two.)

Accepted Answer

A, E

Explanation: 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.

Question 10

An architect is documenting the design for a new multi-site vSphere solution. The customer has
informed the architect that the workloads hosted on the solution are managed by application teams
who must perform a number of steps to return the application to service following a failover of the
workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The
customer has provided the architect with the following information about the workloads, including
the recovery time objective (RTO) and recovery point objective (RPO):
Critical workloads have a WRT of 12 hours
Production workloads have a WRT of 24 hours
Development workloads have a WRT of 24 hours
All workloads have an RPO of 4 hours
Critical workloads have an RTO of 1 hour
Production workloads have an RTO of 12 hours
Development workloads have an RTO of 24 hours
The customer has also confirmed that production and development workloads are managed by the
same team and the disaster recovery solution will not begin the recovery of the development
workloads until all critical and production workloads have been recovered at the secondary site.
Which three statements would the architect document as the maximum tolerable downtime (MTD)
for workloads within the design? (Choose three.)

Accepted Answer

A, B, F

Explanation: Critical Workloads: 12 hours For critical workloads, the recovery time objective (RTO) is 1 hour, and the work recovery time (WRT) is 12 hours. Since the customer can tolerate a maximum of 12 hours to restore these workloads after a disaster, the MTD for critical workloads is 12 hours. Development Workloads: 24 hours For development workloads, the RTO is 24 hours and the WRT is also 24 hours. Therefore, the MTD for development workloads is 24 hours because it is the maximum time that the customer can tolerate for these workloads to be unavailable. Production Workloads: 24 hours Production workloads have an RTO of 12 hours and a WRT of 24 hours. Since the disaster recovery solution waits for the recovery of critical and production workloads before recovering development workloads, the MTD for production workloads can be up to 24 hours, including the time to fully recover both critical and production workloads.

Question 11

An architect is holding a requirements workshop with a customer for a new vSphere solution design.
The customer states that the solution should make it easy to identify and apply patches or updates to
ESXi hosts, including the ability to pre-stage the files on the ESXi hosts.
Which design quality is being referenced by the customer?

Accepted Answer

B

Explanation: The customer's requirement for making it easy to identify and apply patches or updates to ESXi hosts, including pre-staging the files, is focused on simplifying the management of the vSphere environment. This is a key aspect of manageability, which refers to the ease with which IT administrators can handle tasks like patching, updates, and configuration management in a consistent and efficient manner.

Question 12

An architect is designing a new vSphere-based solution for a customer.
During a requirements gathering workshop, the following information is provided:
0The solution must have a primary and secondary (isolated) environment
The solution must support orchestration to address application dependencies
The isolated environment must be able to scale on demand in case of a DR scenario
The solution is managed through a single interface
Which solution should the architect include in this design?

Accepted Answer

B

Explanation: 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.

Question 13

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, 200 GB disk
- Production:
-- 50 x Small: 1 vCPU, 2 GB RAM, 200 GB disk
-- 100 x Medium: 2 vCPU, 4 GB RAM, 200 GB disk
-- 25 x Large: 4 vCPU, 8 GB RAM, 500 GB 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 10 TB 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.)

Accepted Answer

A, C, D

Explanation: 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 14

A company has the business goal of automated, centralized, and efficient management of the data center. Which statement would be included in the conceptual design to support this business goal?

Accepted Answer

D

Explanation: To support the business goal of automated, centralized, and efficient management of the data center, joining all vCenter instances to a single vCenter Single Sign-On (SSO) domain helps in streamlining management and improving security. By centralizing authentication and enabling single sign-on, the organization can achieve a more efficient and consistent management experience across the entire data center. This eliminates the need to manage multiple authentication systems, allowing for better integration, automation, and centralized control over all vCenter instances.

Question 15

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?

Accepted Answer

B

Explanation: 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.
