3V0-21.23 Exam Questions and Answers

QUESTION: 6

The following is a list of requirements from a discovery workshop for a new VMware hosting platform system design:

REQ01 - The architecture must support recoverability to the VMware Cloud Disaster Recovery (VCDR) service.

REQ02 - The architecture must support high availability (HA) and fault tolerance (FT).

REQ03 - The architecture must support reducing existing energy consumption and carbon footprint.

REQ04 - The architecture must provide support for network virtualization using distributed virtual switches.

Which requirement would be classified as a business (formerly functional) requirement?

The architecture must support high availability (HA) and fault tolerance (FT).
The architecture must support reducing existing energy consumption and carbon footprint.
The architecture must support recoverability to the VMware Cloud Disaster Recovery (VCDR) service.
The architecture must provide support for network virtualization using distributed virtual switches.

Answer(s): 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: 7

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?

The company has previously worked with multiple VMware partners.
The company has an Enterprise License Agreement (ELA) with VMware.
The company has an internal security policy that is referenced in long running contracts.
The company has a multi-year cloud subscription agreement.

Answer(s): 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.

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?

The architecture will extend the Fibre Channel external storage array, scaling out storage and compute by buying additional storage or server capacity as required.
The architecture will replace the Fibre Channel storage array with an updated model, scaling out storage capacity as required.
The architecture will be based on vSAN Ready Nodes, scaling out storage and compute by buying additional hyper-converged servers as required.
The architecture will be based on stretched vSAN Ready Nodes, scaling out storage and compute by buying additional hyper-converged servers as required.

Answer(s): 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 responsible for extending the hosting design for a customer. The customer has a mission-critical 3-node application which is load balanced in an active/active/passive configuration. The application administrator requests that the virtual infrastructure team be responsible for maintaining platform level availability. An organizational policy exists to mandate the highest possible availability for mission-critical applications.

Based on the resource requirements, the architect has made the following design decision:

The target vSphere cluster contains three VMware ESXi host servers

A combination of which additional four physical design decisions should the architect make to maximize availability of the application? (Choose four.)

The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.
The solution will enable vSphere High Availability (HA) with restart priority set to "Highest" for the application virtual machines.
The solution will create a VM-VM Affinity rule to keep virtual machines separate.
The solution will create a host DRS group containing all hosts within the cluster.
The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.
The solution will create a virtual machine DRS group that contains all of the critical application workloads.
The solution will create a VM-VM Affinity rule to keep virtual machines together.

Answer(s): A,B,E,F

Explanation:

The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.

Creating a VM-Host Affinity rule ensures that specific workloads are restricted to certain hosts, which can be useful to avoid placing critical applications on hosts that may not meet their availability requirements.

The solution will enable vSphere High Availability (HA) with restart priority set to "Highest" for the application virtual machines.

Enabling vSphere HA ensures that virtual machines are automatically restarted on other hosts in the event of a host failure. Setting the restart priority to "Highest" for mission-critical VMs ensures that these VMs will have the highest priority for restart if any issues arise.

The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.

Enabling vSphere Fault Tolerance (FT) ensures that the application VMs are fully protected by creating a live shadow VM that runs in lockstep with the primary VM. In the event of a host failure, the shadow VM will take over instantly, providing continuous availability for the application.

The solution will create a virtual machine DRS group that contains all of the critical application workloads.

Creating a virtual machine DRS (Distributed Resource Scheduler) group for critical workloads ensures that these VMs are placed and migrated to the optimal hosts based on the cluster's resource requirements, improving availability and performance.

QUESTION: 10

An architect is reviewing the information provided by a customer for a new vSphere solution design. The customer has stated that some of the virtual machines (VMs) that will be hosted on the new solution handle credit card information from their users as part of an online payment application, and that some of the information will need to be stored temporarily to allow transactions to be completed. Therefore, the solution must be designed to be able to mask or hash the stored information as they will need to show compliance against common industry standards that contain references to the requirements for handling sensitive information.

Which design quality is being requested by the customer?

Manageability
Performance
Security
Recoverability

Answer(s): C

Explanation:

The customer is requesting that the solution meet security requirements, specifically around handling sensitive information (such as credit card data). The need to mask or hash stored information for compliance with industry standards (e.g., PCI-DSS) is a security-focused design requirement. This ensures that sensitive data is protected and compliant with regulations, making security the primary design quality being requested.
