Question

Scenario: CGE decided to virtualize its infrastructure workloads and provide a virtual solution to all end users. The infrastructure workloads include Delivery Controllers, StoreFront servers, License Servers, and Microsoft SQL Servers for databases. Why is using a maximum of 32 XenServer hosts, using a shared virtual disk storage repository for XenMotion, high availability, and the replication and backup of meta information the best design for the resource pools?

Options

  • AIt addresses all customer requirements by ensuring appropriate design of resource pools, high
  • BIt ensures simple setup with redundancy.
  • CIt bases resource pools on roles, and facilitates the movement of workloads from one resource pool to
  • DIt ensures the separation of infrastructure and virtual desktop workloads, which optimizes performance

Why each option

The design using a maximum of 32 XenServer hosts with shared storage aims to separate critical infrastructure workloads from user virtual desktop workloads. This separation is a best practice to optimize performance and prevent resource contention between different workload types.

AIt addresses all customer requirements by ensuring appropriate design of resource pools, high

'Addresses all customer requirements' is a general statement and does not provide the specific technical justification for why a maximum of 32 XenServer hosts and workload separation is the best design.

BIt ensures simple setup with redundancy.

While the design incorporates redundancy (shared storage for HA), 'simple setup' is subjective and not the primary technical reason for this specific design choice regarding resource pool size and workload separation.

CIt bases resource pools on roles, and facilitates the movement of workloads from one resource pool to

The scenario describes separating infrastructure and virtual desktop workloads, not necessarily basing resource pools on roles or facilitating workload movement between different resource pools as the primary benefit of this specific design choice.

DIt ensures the separation of infrastructure and virtual desktop workloads, which optimizes performanceCorrect

Separating infrastructure workloads (Delivery Controllers, StoreFront, License Servers, SQL) from virtual desktop workloads is a critical best practice in virtualization environments. This isolation ensures that the performance of vital backend services is not negatively impacted by the variable and potentially high resource demands of user desktops, and vice-versa, thereby optimizing overall system performance and stability.
