3V0-21.23 Exam Dumps - VMware vSphere 8.x Advanced Design

Separate clusters in DC1 and DC2 provide logical isolation between the two data centers. This means that an accidental change or misconfiguration in one cluster (e.g., DC1) will not affect the other cluster (e.g., DC2). This isolation meets the customer's requirement to limit the impact radius of accidental changes by administrators. By having separate clusters, the risk of cross-site or cross-cluster disruptions is minimized, ensuring better fault tolerance and administrative control.

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.

The storage may not have capacity to accommodate 20% year-over-year virtual machine growth.

This is a risk because, while the assumption is that the storage hardware has sufficient capacity, there is a possibility that the hardware may not be able to support future growth, especially if the customer's workload grows faster than expected. Documenting this risk ensures that the design considers potential capacity constraints.

The customer may not have an existing licensing subscription that covers features the architect intends to use.

This is a risk because although the assumption is that the customer will provide licensing, there may be discrepancies between the features required for the design and the customer’s existing licensing. This risk ensures that the architect verifies that the customer’s licensing aligns with the solution requirements.

Fibre Channel is the Recommended Storage Technology for the Brownfield vSphere Deployment

Given the constraints of the brownfield site, the existing infrastructure, and the approved budget, the architect should recommend leveraging the existing Fibre Channel storage technology.

Here's the reasoning based on the provided requirements:

Utilize Existing Storage Array:The crucial constraint is that the budget is only for new server and network hardware, explicitly excluding the purchase of a new storage array. The solutionmustutilize the existing storage array.

Existing Fibre Channel Connectivity:The current storage array is already connected via Fibre Channel with a dedicated SAN fabric (2 x 8 Gbps interfaces). This existing infrastructure can be directly leveraged with new servers equipped with Fibre Channel HBAs.

Budget Alignment:Reusing the existing Fibre Channel SAN aligns with the budget approval for only new server and network hardware (to connect the servers to the existing SAN). Introducing a different storage technology like iSCSI or NFS as the primary method would likely require significant network infrastructure changes or additions beyond standard server networking, which may not be covered by the approved budget for "new server and network hardware only." While the arraycansupport NFS, the existing high-speed, dedicated storage connectivity is Fibre Channel.

Incompatibility with vVols:The existing storage array does not support vSphere API for Storage Awareness (VASA), which is a mandatory requirement for implementing vSphere Virtual Volumes (vVols). Therefore, vVols is not a viable option with the current storage hardware.

vSAN Not Applicable to Existing Array:VMware vSAN is a software-defined storage solution that pools local storage from ESXi hosts. It does not directly utilize external Fibre Channel SAN arrays as its primary storage pool in the standard configuration. Implementing vSAN would require a significant investment in server local storage, which falls outside the scope of using theexisting storage array.

Manageability:The existing vSphere administration team is responsible for operational management. Fibre Channel storage is a mature and commonly used storage technology in vSphere environments, meaning the existing team is likely to have the necessary skills to manage it.

While the existing arraycanbe configured for NFS, leveraging the existing Fibre Channel connectivity is the most direct and budget-aligned approach given that the SAN fabric and FC interfaces are already in place and the budget is restricted to server and network hardware for connectivity.

Based on VMware vSphere 8.x Advanced documentation and standard IT architecture practices, the architect is designing a new VMware vSphere solution and must identify a business factor that will impact the design. A business factor is a high-level organizational or strategic consideration that influences the design, typically related to goals, policies, financial constraints, or contractual obligations, as opposed to technical or operational details.

Requirements Analysis:

Business factor: This refers to a non-technical, strategic element that shapes the vSphere design, such as corporate policies, financial agreements, or business objectives. It impacts decisions like security, compliance, licensing, or integration with existing strategies.

Provided information:

The company has worked with multiple VMware partners (historical vendor relationships).

The company has an internal security policy referenced in long-running contracts (compliance and security obligations).

The company has an Enterprise License Agreement (ELA) with VMware (licensing and cost structure).

The company has a multi-year cloud subscription agreement (cloud strategy alignment).

Evaluation of Options:

A. The company has previously worked with multiple VMware partners:

Why incorrect: While prior partnerships with VMware partners may influence vendor selection or implementation expertise, this is a historical operational detail, not a strategic business factor. It does not directly impact the design’s architecture, such as security, licensing, or workload placement, unless explicitly tied to ongoing obligations (not indicated here).

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.

The solution will deploy VMware vSphere Enterprise Plus on all hosts within the cluster.

VMware vSphere Enterprise Plus offers advanced networking and storage features that will support the required high availability, performance, and management capabilities. Features such as Distributed Switches and Network I/O Control (NIOC) are critical to meeting the business-critical application and performance requirements for the latency-sensitive stock trading application.

The solution will deploy a single vSphere Distributed Switch with each host connected to it.

A vSphere Distributed Switch (VDS) is ideal for managing network configurations centrally across multiple hosts, which meets the requirement for centralized vSphere operational management. It also ensures consistent network configurations and simplifies network management at scale.

The solution will configure Network I/O control to ensure that system-level bandwidth does not impact workload network traffic.

Network I/O Control (NIOC) is essential for prioritizing network traffic, ensuring that latency-sensitive workloads are not impacted by other system-level or less critical traffic. This is crucial for the performance requirements of the stock trading application.

Design phase: The purpose of the Design phase is to define how the solution will meet the specific requirements. During this phase, the architect works closely with stakeholders to understand their needs and translate those needs into a technical design. A key activity in this phase often involves refining the solution details through interviews and discussions with key stakeholders to ensure that the design aligns with the business and technical requirements.
