Nutanix NCP-EUC Practice Test Questions Answers

According to Nutanix and Microsoft best practices for Windows 11 on AHV, the operating system has significantly higher CPU overhead compared to previous versions due to mandatory security features like Virtualization-Based Security (VBS) and Hypervisor-Protected Code Integrity (HVCI).

While the minimum requirement for Windows 11 is 2 vCPUs, this configuration is often insufficient for an acceptable user experience in a VDI environment where users are running concurrent applications. Performance analysis indicates that 2 vCPUs results in high CPU Ready time and sluggishness. The recommended configuration to resolve these performance bottlenecks is to increase the CPU allocation to at least 3 vCPUs (typically 4 vCPUs is the standard "sweet spot" for Windows 11 VDI), ensuring enough compute cycles are available for both the OS overhead and user workloads.3

Nutanix Files VDI Sync is a feature originally designed for active-active use cases where users might access data from either site, requiring bidirectional metadata scanning and locking. This process is resource-intensive.

For a Disaster Recovery (DR) purpose where the secondary site is passive (users only access it if the primary fails), full active-active bidirectional synchronization is unnecessary and wasteful. To reduce the high CPU and RAM utilization caused by the constant metadata comparison between sites, the administrator should configure one-way synchronization (or leverage standard Async DR protection). This ensures data replicates to the DR site without the overhead of checking the DR site for changes to replicate back to the source.

To resolve issues with persistence (retaining settings) and login performance in a non-persistent VDI environment, the industry standard and Nutanix-recommended solution is to Enable a Virtual Disk-based profile solution (such as FSLogix Profile Containers or Citrix Profile Management containers).

Retaining Settings: Unlike local profiles (wiped on reboot) or mandatory profiles (read-only), containerized profiles capture all user writes and persist them to a VHD/VHDX file on a file share (e.g., Nutanix Files).

Speed: Microsoft Roaming Profiles (Option A) require copying files over the network at login, causing slowness. Virtual Disk-based solutions mount the profile disk instantly over the network, making the login process nearly as fast as a local profile while ensuring data persistence.

one of the possible Nutanix storage efficiency features that the administrator can use for this solution is Deduplication. Deduplication is a technology that eliminates duplicate blocks of data and reduces storage consumption. Deduplication can be enabled on a per-container basis and can provide significant savings for Citrix virtual desktop deployments that use cloning technologies such as Machine Creation Services (MCS) or Provisioning Services (PVS)1.

To support non-disruptive operations for sensitive workloads such as VDI user profiles (e.g., FSLogix or Citrix Profile Management), Nutanix Files supports Continuous Availability (CA) for SMB shares.

Standard SMB shares may experience a brief pause or disconnect during an FSVM failover or upgrade (rolling reboot), which causes VDI profile containers to detach, leading to application crashes or session hangs. Continuous Availability enables persistent file handles, allowing the client session to transparently failover to another FSVM node without disconnecting the application or user session. This is the specific feature designed to address connectivity issues during maintenance windows for VDI workloads.
