NCP-EUC Exam Dumps : Nutanix Certified Professional - End User Computing (NCP-EUC) 6.10 Exam

A gold image is a master image that contains the operating system, drivers, patches, and configurations for a virtual desktop. A non-persistent Citrix MCS environment is one where virtual desktops are created from a gold image and discarded after each user session.

Citrix Machine Creation Services (MCS) is a tool that uses a gold image to create and manage virtual machines for Citrix Virtual Apps and Desktops environments. MCS can create different types of machines, such as pooled random, static assigned, or dedicated2.

One of the challenges of using MCS is managing multiple gold images for different user groups or application needs. Updating multiple gold images can be time-consuming and error-prone. Therefore, it is recommended to use a single base image without any applications and leverage another tool such as Microsoft System Center Configuration Manager (SCCM) to deliver applications dynamically to the cloned virtual desktops3.

This approach can simplify image management, reduce storage consumption, improve performance, and enhance user experience. SCCM can also provide additional features such as patch management, compliance enforcement, inventory reporting, etc.3

Comprehensive and Detailed Explanation From Exact Extract of Nutanix End User Computing documents:

According to Citrix Virtual Apps and Desktops architecture documentation utilized in Nutanix EUC designs:

VDA Functionality: The Virtual Delivery Agent (VDA) is the essential software component that must be installed on every machine (virtual or physical) that delivers applications or desktops.

FMA Role: The VDA registers with the Delivery Controller (Broker) and manages the FMA (FlexCast Management Architecture) connection between the machine and the user device. It establishes and manages the HDX connection, allowing the Citrix Workspace app (on the client side) to connect directly to the desktop session.

Distinction:

Citrix Workspace app is installed on the client device (endpoint), not the virtual desktop.

VirtIO drivers are lower-level drivers for disk/network I/O virtualization on AHV, not FMA connection brokers.

NGT provides Nutanix-specific fabric features (SSR, FLR), not Citrix session connectivity.

According to the Nutanix AHV Administration Guide and Cluster Expansion prerequisites for environments with non-default virtual switches:

Manual Bridge Configuration: When a cluster has multiple virtual switches (e.g., vs1, vs2) configured, these correspond to specific OVS bridges (e.g., br1, br2) on the AHV hosts. Before adding new nodes to such a cluster, the administrator must manually configure these additional bridges on the new nodes to match the existing cluster configuration.

Consistency Requirement: The documentation states that virtual bridges used for a virtual switch (VS) on all nodes must have the same specification (name, MTU, uplink bond type). If vs1 is mapped to br1 on existing nodes, it must be mapped to br1 on the new nodes before they are added to the cluster.

Expansion Failure/Warning: Failure to configure these bridges prior to expansion can result in the new nodes being unable to join the configured networks properly or the expansion process failing checks related to network uniformity.
