Pass the Citrix Citrix Virtual Apps 1Y0-204 Questions and answers with CertsForce

Citrix power management requires:

A hypervisor connection (Citrix Hypervisor, Hyper-V, VMware, Nutanix AHV)

Machines created or managed by Citrix Studio

The ability for Delivery Controllers to send power commands through the hypervisor API

Citrix documentation clearly states:

✔ Only virtual machines registered in a hosting connection support power actions such as:

Power on

Power off

Restart

Suspend / resume (depending on hypervisor)

✔ Virtual Desktop OS VDAs (typically Windows 10/11 or Windows 365-style desktops) support full power management because they run as virtual machines on the hypervisor.

Why the other options are incorrect:

Remote PC Access machines (A):Are physical desktops; power actions cannot be controlled via hypervisor APIs.

Virtual Server OS machines (B):Although virtual, they are normally used as multi-session hosts; Citrix power management is not intended for them in standard deployments.

Physical Server OS machines (D):Physical hardware is not managed through hosting connections, so no power control is possible.

Thus, Virtual Desktop OS machines are the correct answer.

Citrix Director can capture utilization statistics for CPU, IOPS, and memory for each machine in a selected delivery group1. The resource utilization tab in the trends page displays the historical data for these metrics, along with the peak concurrent sessions graph2. The machine statistics page also shows the CPU and memory usage of the selected machine over time, as well as the processes contributing to high resource consumption3. Citrix Director does not capture utilization statistics for disk space or network, but it does provide other information related to these components, such as disk latency4 and network analysis5.

When deploying a Citrix Virtual Apps and Desktops Site with SQL database mirroring, Citrix requires that the collation setting used by the Site database must be explicitly set and must match the required Citrix standard. Citrix documentation states that the database collation must be case-insensitive and consistent between the principal and mirror SQL servers.

This collation is not automatically assigned by SQL Server when you create an empty database for mirroring. Therefore, administrators must manually configure the correct collation during initial creation. If the collation does not match Citrix requirements, the Site creation or Controller functionality may fail.

Other listed options (SQL version, database type, mirroring version) do not require manual configuration at database-creation time for Citrix Sites.

According to the Citrix documentation1, Citrix Workspace app for Windows supports both pass-through authentication and session pre-launch features, which are required by the management in this scenario. Pass-through authentication allows users to log on to the Citrix Workspace app without entering their credentials, and session pre-launch enables sessions to be started in the background before users request them. The other options do not support both of these features.

 Process Explorer is a tool that can be used to get further details on orphaned processes in the session. According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course, Process Explorer can be used to “identify processes that are preventing a session from logging off” (Module 6: Troubleshooting User Connection Issues, Lesson: Troubleshooting Session Logon and Logoff Issues, Slide 8). Additionally, according to the Citrix Virtual Apps and Desktops 7 Administration Exam Guide, one of the objectives is to “use Process Explorer to identify orphaned processes” (Objective 6.3: Troubleshoot Session Logon and Logoff Issues). Therefore, Process Explorer is the correct answer.

 The Secure Ticket Authority (STA) server locations must be configured on the Citrix Gateway and StoreFront to facilitate secure external access. The Citrix Gateway uses STA to validate session requests and the StoreFront communicates with the STA to manage user sessions securely.

The commands in the screenshot create a responder action and policy that modify the DNS response from the Citrix ADC to the client. The responder action uses the DNS.NEW_RESPONSE function, which creates a new DNS response with the specified parameters. The first parameter is true, which means the response will have the TC (truncated) bit set. The second parameter is true, which means the response will have the AA (authoritative answer) bit set. The third parameter is NOERROR, which means the response will have the rcode (response code) set to NOERROR. The responder policy matches the DNS requests that use UDP as the transport protocol and applies the responder action to them. Therefore, the effect of this configuration is to create a DNS response with TC bit set and rcode as NOERROR for UDP requests. This can be used to prevent DNS amplification attacks by limiting the size of the DNS response.
