Question 107

Scenario: A Citrix Architect is designing a new, 2,000-user XenApp and XenDesktop environment. The environment will use Windows Server 2016 for all Site infrastructure components (Delivery Controllers, StoreFront servers, Citrix Director). Machine Creation Services (MCS) will be used to provision Virtual Delivery

Agent (VDA) machines.

The environment will include two primary use cases:

✑ Windows Server 2016 VDA machines providing hosted apps

✑ Windows 10 VDA machines providing random, non-persistent VDI

The IT team has NOT yet purchased the hardware that will be used for the environment and will build the Hardware Layer components for the environment based on the architect's recommendations.

How should the architect design the hypervisor resource pools based on Citrix leading practice?

    Correct Answer: C

    According to Citrix leading practices for designing XenApp and XenDesktop environments, workloads with different requirements should be placed in separate resource pools. The infrastructure servers (such as Delivery Controllers, StoreFront servers, and Citrix Director) generally have different resource usage patterns and requirements compared to the Virtual Delivery Agent (VDA) machines. Within the VDA machines, Windows Server 2016 VDA machines providing hosted apps and Windows 10 VDA machines providing random, non-persistent VDI also have different characteristics and should be separated for optimal performance and management. Therefore, Windows Server 2016 VDA machines should be placed in one resource pool, Windows 10 VDA machines in a second, and infrastructure servers in a third resource pool.

Discussion
ijhoojhisdojihoijOption: C

C. When implementing a XenApp and XenDesktop deployment, the workloads for the infrastructure, XenDesktop, and XenApp workloads can be separated into dedicated resource clusters or mixed on the same physical hosts. Citrix recommends using resource clusters to separate the workloads, especially in an enterprise deployment. This allows better host sizing as each workload has unique requirements such as overcommit ratios and memory usage. https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/citrix-vdi-best-practices/design/design-userlayer5.html

This is not very clear, as XenApp-XenDesktop is considered as one workload type (aka VDA workload). I was informed in training class that to separate VDAs from Infra servers. D could also be right.

neogeo_604erOption: C

I Choose C. This is taken directly from the Citrix training material "Citrix leading practice is to dedicate a resource pool: • 1 for the Infrastructure • 1 for each VDA workload type. • For example, have a separate cluster for Multi-Session OS and another for Single-Session OS."
