According to the Citrix Virtual Apps and Desktops 7 Advanced Administration guide1, the administrator can use custom access in Citrix Cloud to grant the contractor access to specific services and features, such as the Citrix Virtual Apps and Desktops Service. The administrator can also use the Delivery Group Administrator role in the Citrix Virtual Apps and Desktops Service to allow the contractor to deliver applications, desktops, and machines, and manage the associated sessions. This role has the minimum permissions required to administer the inventory application. The other roles are either too broad or too restrictive for the scenario.

According to the Create store page from the Citrix Product Documentation, the administrator can create a store for unauthenticated users by ticking the option “Allow only unauthenticated users to access this store” when creating the store. This option is suitable for contractors who will not be Active Directory users and need access to specific resources. The other options (HTTP Basic, Smart card, and Pass-through) are authentication methods that require user credentials.

 According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration (CWS-215) course, the Citrix ADC can optimize the responses by using HTTP protocol for the services and SSL protocol for the virtual server. This configuration allows the Citrix ADC to terminate the SSL connection from the client and then communicate with the server using HTTP. This way, the data is encrypted between the client and the Citrix ADC, and the Citrix ADC can perform optimization tasks such as compression and caching1: Page 95, Module 5: Citrix Gateway and Citrix StoreFront Integration.

To secure XML traffic between StoreFront and Delivery Controllers, a Citrix Administrator must install a private server certificate on each Delivery Controller and bind the certificates to port 4431.

The Virtual Delivery Agent (VDA) is a software component that enables machines to deliver applications and desktops to users. The VDA registers with a Delivery Controller and communicates session information to the Controller, which brokers connections between users and their resources. Users access their resources through Citrix Workspace app or a compatible web browser1

Application Prelaunch is a feature that allows users to launch applications faster by creating a session when the user logs on to Citrix Workspace app, before the user requests an application. This feature is enabled by Delivery Group and can be configured for all users or a subset of users1.

Session Sharing is a feature that allows users to launch multiple applications using the same session, reducing the load on the server and improving the user experience. This feature is enabled by default and can be configured using Citrix policies2.

The issue is caused by the policy expression of the no_chunk_pol being ‘true’ and ‘NOT HTTP.REQ.IS_VALID’. This means that the policy will always be true and thus, always be invoked, preventing the other policy from being used. This is explained in the Citrix Virtual Apps and Desktops 7 Deployment and Administration (CWS-215) course, under the section “Load Balancing Virtual Server Rewrite Policy Binding”.

 According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course, one of the methods to configure the Citrix Workspace app is to use a Group Policy Template File. This file contains the settings that can be applied to the Citrix Workspace app through Active Directory Group Policy. This method allows the administrator to specify the server address and other settings for the users, so they do not have to remember or enter them manually1

1: 2 - Configuring Citrix Workspace app using Group Policy Template File.

After configuring TLS certificates on Cloud Connectors and disabling HTTP connections, the administrator needs to change the transport type to HTTPS in the StoreFront store’s Delivery Controller list to allow resource enumeration between on-premises StoreFront and Citrix Cloud4.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration guide1, the HDX Printer properties retention policy has four possible settings:

Held in profile only if NOT saved on client: This is the default setting. The printer properties are held in the user profile only if they have not been saved on the user device.

Do NOT retain printer properties: The printer properties are not retained at all. The user must configure them for each session.

Saved on the client device only: The printer properties are saved on the user device only. The user profile does not store them.

Retained in user profile only: The printer properties are retained in the user profile only. The user device does not store them.

In this scenario, the administrator wants the users to maintain the different printer property settings for their HDX sessions. Since the users are using mandatory profiles, which are read-only and do not save any changes, the administrator should use the Retained in user profile only setting. This way, the printer properties are stored in the user profile and applied to the HDX sessions. The user device does not need to save them. This setting is suitable for environments where mandatory profiles are being used.

In Citrix Virtual Apps and Desktops, administrators can use tag restrictions to specify which machines within a Delivery Group are affected by certain power management actions. By applying tags to a subset of machines, the administrator can ensure that only those tagged machines are restarted daily during non-peak hours, while the rest follow the weekly restart schedule.

According to the HDX Insight documentation, HDX Insight is the integration of NetScaler Network Inspector and Performance Manager with Director. It captures data about ICA traffic and provides a dashboard view of real time and historical details. To monitor NetScaler appliances deployed in this mode, first add the NetScaler appliance to the NetScaler Application Delivery Management (ADM) inventory, enable AppFlow, and then view the reports on the dashboard. External users who access Citrix Virtual App and Desktop applications must authenticate themselves on the NetScaler Gateway. Therefore, the three components that the administrator will need to review are:

Citrix Application Delivery Management: This is the platform that collects and analyzes the AppFlow records generated by the NetScaler appliance.

Citrix Gateway: This is the component that provides secure access to the Citrix Virtual App and Desktop applications and generates the AppFlow records for HDX Insight.

Citrix Director: This is the web-based tool that displays the HDX Insight reports and allows the administrator to troubleshoot performance issues.

 The Citrix Universal Print Server provides universal printing support for network printers. The Universal Print Server uses the Universal print driver, a single driver on the Multi-session OS machine that allows local or network printing from any device, including thin clients and tablets. This feature can help reduce the number of Windows drivers on the VDA machines by using a single driver for all network printers

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course, a license upgrade is a cost effective solution that allows an administrator to increase the performance of an existing Citrix ADC appliance without replacing the hardware. A license upgrade can provide more throughput, SSL transactions per second, and compression capability. In this scenario, a license upgrade from MPX 5550 to MPX 5650 can double the throughput and SSL transactions per second, which can handle the forecasted growth of the retail company1

 According to the Citrix documentation1, persistence time-out is the parameter that determines how long the service continues to serve requests from the client after it is disabled manually. The service accepts new requests or connections only to honor persistence. After the persistence time-out expires, no new requests or connections are directed to the service and all of the existing connections are closed. This parameter is available only when the service is disabled gracefully. The default value is 2 minutes. The other options are not related to the scenario described in the question.

 Folder redirection is a feature of Microsoft Windows and can be used with Profile Management. It allows folders, such as Application Data or Documents, to be saved (redirected) to a network location. The contents of the folders are stored in the redirected location and not included within the user profile, which therefore reduces in size. This can improve the logon times for users with large Documents folders1

1: Plan folder redirection with Profile Management

According to the policy priority and filtering, the Accounting users will match the policy “Accounting”, which has ‘Client Network Drives’ enabled and ‘Client Fixed Drives’ not configured. The policy “Baseline” will not apply because it has a lower priority. Therefore, the Accounting users will be able to access only the client network drives, and not the client fixed drives. This is confirmed by the Citrix documentation on policy filtering and precedence.

 According to the Citrix documentation1, HA monitoring should be enabled only on interfaces that are UP on both nodes. If HA monitoring is enabled on a disabled interface of the primary node, the secondary node will not be able to receive heartbeats from the primary node and will not initiate a failover.

VDA registration can be configured using:

Group Policy Object (GPO): Policy-based configuration using LGPO or GPO.

Organizational Unit (OU) based Controller discovery: Legacy OU discovery method.

MCS-based PERSONALITY.INI: Using the personality.ini file for MCS-based deployments.

These methods ensure that the VDA has accurate and current Controller or Cloud Connector information as Controllers are added, moved, and removed in the site1.

According to the Citrix documentation1, the Citrix ADC SDX appliance allows administrators to upgrade the Citrix ADC instances on an individual basis, without affecting the other instances or the SDX appliance. This allows the instances to run different firmware versions and provides flexibility and convenience for the administrator.

The dig +trace command can be used to resolve DNS requests by tracing the path from the root name servers to the authoritative name servers. This can help identify any issues with DNS resolution or delegation. The nslookup command can also be used to query DNS records, but it does not provide the trace option. The curl command can be used to transfer data from or to a server, but it does not resolve DNS requests. The ping command can be used to test the connectivity and latency between two hosts, but it does not resolve DNS requests.

According to the Prepare to install article, the First-Time wizard automatically pops up when the appliance is configured with the default IP address (192.168.100.1) or when licenses are not present on the appliance. Therefore, options C and D are correct. Options A and B are not related to the First-Time wizard.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course description12, the course covers how to deploy and manage machines running the VDA in both on-premises datacenters and public clouds, such as AWS1. The Citrix Virtual Apps and Desktops service also supports Azure and Google Cloud Platform as resource locations for VDAs3. Citrix Cloud is not a resource location, but a platform that hosts the Citrix Virtual Apps and Desktops service3. VMware Workspace One is not a supported resource location for VDAs, but a competing product from VMware.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course description12, one of the objectives is to “Configure Citrix ADC to monitor and report on the health of your environment”. The course also covers how to use Citrix Application Delivery Management to monitor and manage multiple Citrix ADC instances. According to the Citrix documentation3, Network Reporting on Citrix Application Delivery Management allows you to generate reports based on various metrics and events collected from the Citrix ADC instances. You can also configure thresholds and alerts for the reports, and specify the email addresses to receive the notifications. Therefore, the correct answer is D.

B. Citrix Print Manager Service: Monitors session events like logon, logoffs, and session termination to manage printing tasks within the session.

C. Security Descriptor: Sets the default security descriptor for auto-created printers, enhancing the security of client printers in a session.

E. Impersonation: The Citrix Print Manager Service processes print requests by impersonating the session user, ensuring that the user’s permissions are applied to the printing process.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration guide1, to connect to an SSL offload virtual server without any SSL errors, the client must trust the certificate that is bound to the virtual server. This means that the root certificate of the certificate authority (CA) that issued the server certificate must be installed on the client’s device. Additionally, the server certificate must be bound to the load-balancing virtual server that is configured for SSL offload, not to the back-end servers. This way, the Citrix ADC can terminate the SSL connection and communicate with the back-end servers using HTTP or TCP.

Option A is correct because if the VDA machine is not registered with the Site where the Citrix policy was configured, it will not receive the policy settings from the Site database. The VDA machine must register with a Delivery Controller in the Site to apply the Citrix policies1

Option B is correct because the Unfiltered policy is applied to all objects in the Site by default, and it has the lowest priority. If the Unfiltered policy contains settings that conflict with the Citrix policy configured by the administrator, the Unfiltered policy settings will override the administrator’s policy settings. The administrator can either disable the Unfiltered policy or change its priority to avoid this issue2

Option D is correct because if the VDA machine is not able to communicate with the Site database, it will not be able to retrieve the latest Citrix policy settings from the database. The VDA machine relies on the Delivery Controller to communicate with the Site database and apply the Citrix policies3

The Delivery Controller runs the Secure Ticket Authority (STA) and the Citrix XML Service, which are responsible for issuing session tickets in response to connection requests for published applications and desktops on Citrix Virtual Apps and Desktops12. The Citrix Gateway can be configured to use the STA to validate the tickets and allow secure access to the resources3.

Option B is the correct answer because it uses the DROP action to block access to the URLs that match the BAD_URL pattern set. The other options use the RESET action, which only resets the connection but does not prevent access. Also, option C has a typo in the bind responder global command, which would cause an error. Option D has an invalid type argument for the bind responder global command, which should be DNS_REQ_OVERRIDE instead of DNS_REQ. For more information, see the following resources:

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.

In the scenario described, when network connectivity to Citrix Cloud is lost, the Local Host Cache (LHC) feature allows one of the Citrix Cloud Connectors at the resource location to become the primary broker. This enables it to broker new sessions and manage existing HDX connections using the LHC, ensuring continuity of service during outages

The Citrix Workspace Control settings can be modified in the StoreFront console to enable or disable the automatic reconnection of applications and desktops as users move between devices1. This feature is not available in Citrix Studio, Group Policy, or Citrix Workspace app.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration documentation1, the collation sequence for the site database should be _100_CI_AS_KS. This collation sequence is case-insensitive, accent-sensitive, kana-sensitive, and width-insensitive. It is also compatible with the SQL Server mirroring feature. Other collation sequences might cause errors or unexpected behavior when using SQL Server mirroring2.

The Machine Utilization report in the Machine Details page shows the CPU, memory, disk, and network usage of the selected machine over time1. This can help the Citrix Administrator identify any resource bottlenecks or spikes that may affect the performance of the applications launched from the published desktop session. The other reports do not provide information about the machine’s resource utilization, but rather about the user’s connection, session, and application launch failures2.

Citrix Cloud is the hosting platform that minimizes management and maintenance for administrators while maintaining control of the VDA machines1.

Without a bound SSL certificate, the SSL virtual server cannot establish secure connections and will be in a DOWN state.

According to the Citrix documentation, “To enable SSL offloading for a virtual server, you must bind an SSL certificate to the virtual server.”

The image you sent shows the configuration commands for setting up an SSL virtual server and services. However, there is no command to bind an SSL certificate to the virtual server.

Therefore, the correct answer is D. The SSL Certificate is NOT bound to the virtual server.

 A resource location is a collection of resources that you use to deliver applications and desktops to users. It can include Citrix ADC, VDA, Active Directory Domain, and Hypervisor. These resources are required for hosting and managing the machines that deliver apps and desktops to users1. StoreFront, Citrix Director, Citrix Provisioning, and Database are not part of a resource location, but are components of the Citrix Cloud service2.

 According to the Access Control Lists documentation, the add ns acl command is used to create an extended ACL that can filter packets based on various parameters, such as source IP address, source port, action, and protocol. An extended ACL can define the conditions that a packet must satisfy for the Citrix ADC to process the packet, bridge the packet, or drop the packet. Therefore, to bridge traffic originating from 192.168.10.200, a Citrix Administrator can use the following command:

add ns acl bridge_192.168.10.200 BRIDGE -srcIP 192.168.10.200

This command creates an extended ACL named bridge_192.168.10.200 with the action BRIDGE and the source IP address 192.168.10.200. Any packet that matches these conditions will be bridged to the destination without processing by the Citrix ADC.

The Citrix Diagnostic Toolkit is a rapid deployment platform that delivers a suite of tools and automation options in an easy to use structured format that closely resembles the look and feel of any standard Windows application, even though each tool is an independent standalone application. The easy to use built in menus and shortcuts allow you to quickly and effectively configure multi-vector data collection and integrate third party tools for more robust and comprehensive debugging sessions1.

The PowerShell command Get-Service -DisplayName *citrix* is used to display all the Citrix services installed on the Delivery Controller. This command filters services by their display name to only show those related to Citrix, which typically include various components of the Citrix Virtual Apps and Desktops 7 Deployment and Administration.

According to the Delivery Controllers document, Citrix recommends having at least two Controllers on different physical servers for redundancy and scalability in a production site. The document also states that “additional Controllers enable you to handle more users and more applications and desktop requests, and can improve overall responsiveness.” Therefore, the minimum number of Delivery Controllers required to deploy Citrix Virtual Apps and Desktops for 500 users is 2.

The Citrix Universal Generic Printer is a special type of auto-created printer that uses the Citrix Universal Print Driver and does not require any printer drivers to be installed on the server. It can reduce the number of native drivers being used within the Site infrastructure. To use this feature, the administrator must enable the Auto-create generic universal printer policy setting

 Application Prelaunch is a feature that can be enabled to reduce the perceived start time of applications. It prelaunches an application session when the user logs on, so the application is ready when the user needs it, thus reducing the wait time during the initial access

 Citrix Director is the tool designed for monitoring the overall daily performance of a Citrix Virtual Apps and Desktops Site. It provides administrators with insights into the environment’s operations, allowing for proactive management and troubleshooting

 The command set dns parameter -setAABit YES sets the authoritative answer (AA) bit in the DNS response header. This indicates that the Citrix ADC is the authoritative server for the domain name in the query. This can be useful when the Citrix ADC is configured as a DNS proxy server1

According to the Citrix documentation1, the Least Response Time method uses the response time of the monitor probes to determine the best service. However, this method requires that a monitor is bound to each service and that the monitor response times are recorded. Therefore, the virtual server uses the Round Robin method until each bound service has been probed by the monitor at least once. This mode is called startup round robin mode2.

 The minimum built-in delegated administration role required to create an Application Group is the Delivery Group Administrator. This role has the necessary permissions to manage application groups within a delivery group1.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course, the Citrix ADC maintains a revision history of the configuration files, which can be used to restore a previous configuration in case of accidental changes or deletions. Restarting the Citrix ADC, running HA file synchronization, or running Save v/s Running configuration will not undo the changes made by the administrator. Therefore, the correct answer is A. Restore from revision history1
