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

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.

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.

The design became constrained when the customer required the use of the corporate Active Directory Domain Services (AD DS) solution. The security team's intervention and insistence on using the corporate Active Directory effectively limited the options available for the authentication solution, as OpenLDAP was no longer a valid choice. At this point, the solution's scope was restricted to ensure compatibility with the customer's existing Active Directory infrastructure, which imposed a specific requirement on the design.
