VMware 3V0-21.23 Exam Dumps

In this scenario, the requirement is to ensure that only Production workloads are recovered in the event of a host failure during maintenance, while Development workloads are not restarted. This can be achieved using vSphere HA settings.

By configuring the vSphere HA Host Failure Response to Restart VMs, the system will attempt to restart VMs when a host failure occurs.

Setting the Restart Priority for Development VMs to Disabled ensures that these VMs will not be restarted during a failure event, even though the cluster is set to restart VMs in the event of a host failure. This way, only the Production workloads will be restarted, meeting the customer's requirement.

The customer's requirements include the following:

Carry over existing VLANs for workloads: This can be easily achieved with a vSphere distributed switch (VDS), as it supports the configuration of VLANs and ensures that they can be applied to multiple ESXi hosts across the data center.

Networking for storage must not share the data path with workload traffic: By using aggregated uplinks in the VDS configuration, the architect can easily separate workload traffic and storage traffic by using different uplinks or VLANs. Aggregated uplinks ensure that there is sufficient bandwidth for both workloads and storage, while keeping them logically separated in terms of traffic management.

Add additional VLANs: A VDS supports the dynamic addition of VLANs. New VLANs can be added and managed centrally, reducing the complexity and management overhead when scaling the network.

Reduce management overhead: The use of a single VDS significantly reduces management complexity compared to managing multiple vSphere standard switches (VSS). With VDS, network configuration and management are centralized and simplified across all ESXi hosts.

Given that the new replacement servers have two 100 GB network cards, the aggregated uplinks in a VDS configuration will provide the required network capacity while ensuring that traffic is properly segmented and scalable.

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.

Network I/O Control (NIOC) is a key feature available with distributed virtual switches (vDS) that allows administrators to prioritize and allocate bandwidth to specific network traffic types. It ensures that business-critical applications receive the necessary bandwidth and maintain a consistent quality of service (QoS). This solution meets the requirement to ensure optimal network bandwidth allocation and service consistency.

Deploy all DPU-enabled VMware ESXi hosts into a dedicated VMware vSphere cluster:

Since the customer has a mission-critical, latency-sensitive stock trading application, it is essential to dedicate resources to these workloads to avoid contention with other less critical workloads. By placing DPU-enabled ESXi hosts in a dedicated cluster, the architect ensures that the hardware acceleration provided by the DPUs can be fully utilized by the latency-sensitive application without interference from other workloads.

Configure network offloads compatibility to support DPUs:

DPUs can offload network-related tasks from the CPU, such as network packet processing, and ensure better performance and lower latency. By configuring network offload compatibility in VMware ESXi, the system will leverage the DPU's capabilities to offload network traffic processing, reducing the CPU burden and improving network performance for latency-sensitive applications.

Deploy new vSphere distributed switches (8.0.0) and connect the new DPU-enabled hosts:

For optimal support and performance with DPU-enabled hosts, the architect should deploy vSphere distributed switches (VDS) version 8.0.0. The newer version will be optimized for the hardware and provide better integration with DPUs, ensuring the latest features, improvements, and support for DPUs, thus maximizing the performance and minimizing latency for mission-critical applications.
