1Y0-204 Citrix Virtual Apps and Desktops 7 Administration exam Questions and Answers

According to the Citrix documentation, Citrix Director supports exporting reports in the following formats: PDF, XLS, and CSV. DOC and TXT are not supported. See Export reports and SCOM alerts for more details.

Citrix Studio is the management console that allows administrators to provide customized permissions, including adding applications to junior administrators1.

According to the Citrix Cloud documentation, when migrating existing VDAs to Citrix Cloud, the administrator must update the VDA software on the master image to communicate with the Cloud Connectors. This ensures that the VDAs can register with the Delivery Controllers in Citrix Cloud. If the VDA software is not updated, the VDAs will not be able to register with Citrix Cloud. Therefore, option A is the correct answer. The other options are not relevant to the registration issue.

The Cloud Connector requires outbound connectivity on port 443 for communication with the internet2

 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.

Option B is correct because spillover policies are applied on the GSLB virtual server level, not on the individual GSLB service level. Therefore, the user cannot have a backup for a subset of GSLB services1.

Option C is correct because the selection of a GSLB service is based on the load balancing method configured on the GSLB virtual server, which applies to all the GSLB services bound to it. The user cannot restrict the selection of a GSLB service from a subset of GSLB services for the given domain1.

Option A is incorrect because an administrator can define a backup for a backup Vserver in an active standby GSLB setup for a given GSLB domain by using the backup domain option2.

Option D is incorrect because a GSLB Vserver can load-balance multiple FQDNs by using the domain list option

According to Citrix documentation, to make a configuration change for a StoreFront server group, the change should be made on one StoreFront server in the group, and then the Propagate Changes feature should be used to synchronize the change across the group1

The absence of a power-manage option during the creation of a new machine catalog in Citrix Virtual Apps and Desktops is typically due to the lack of a defined resource connection in Citrix Studio2.

According to the Citrix Printing Quick Start Guide1, Citrix recommends that you disable Direct connections to print servers if your Worker VMs and print servers are not in the same LAN. This is because in this situation the print job sent direct to the print server is not compressed. When the print job is routed via ICA it is compressed. This setting can be configured via Citrix policy under Printing > Client Printers > Direct connections to print servers2. Disabling this setting will allow users to print to both print servers via the ICA protocol. The other options are not relevant to the issue or the scenario.

 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.

Citrix Director provides a feature under the Trends section where administrators can configure and review application faults. This allows them to monitor and analyze applications that have crashed, helping to identify patterns or recurring issues.

The expression B matches the required traffic because it uses the IN_SUBNET function to check if the source IP address belongs to the subnet 10.107.149.0/24, and it uses parentheses to group the logical OR condition for the destination port being either UDP or TCP 53. The other expressions are either syntactically incorrect or do not match the subnet correctly. See Policy Expressions and Classic Expressions for more information.

This expression matches the host name ‘www.example.com’ in all HTTP requests by using the EQ operator, which performs a case-sensitive string comparison. The other options are incorrect because they either use the wrong message type (HTTP.RES instead of HTTP.REQ), the wrong method (HOSTNAME instead of HOSTNAME.EQ), or the wrong operator (CONTAINS instead of EQ). For more information, see  HTTP expressions and Operators in the Citrix documentation.

 According to the Citrix documentation, automatic HA synchronization will fail if the primary and secondary Citrix ADCs have different build versions. The build versions must be the same for the configuration to be synchronized. A manual synchronization, a configuration change to the primary Citrix ADC, or a force failover will not affect the automatic HA synchronization1

The Group Policy Object administrative template, which includes the ADMX and ADML files, is recommended for configuring Citrix Workspace app settings at the domain level. This allows the settings to be applied across various user devices within the enterprise

To stop the automatic creation of all client printers and map printers based on location, the administrator should configure the Auto-create client printers policy to ‘Do not auto-create client printers’, and use the Session printers policy to map printers to users based on their session’s connection location2.

 The nsconmsg tool can be used to display the policy bound hits on a Citrix ADC appliance. This tool can show the number of times a policy was evaluated and the number of times it was hit. The nsconmsg tool can also display other statistics and information about the Citrix ADC configuration and performance1

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration guide, the expression CLIENT.SSL.CLIENT_CERT.VALID_NOT_AFTER.EQ(GMT2020) checks whether the client certificate is valid until the specified date (GMT2020). The other expressions are either incorrect or irrelevant for this requirement.

According to the Citrix documentation1, when user subscriptions are disabled for a store (Mandatory Store), the following behaviors occur:

Users cannot subscribe to applications from the store. All the applications in the store are automatically subscribed to each user and appear in Citrix Workspace app.

Users cannot remove applications from Citrix Workspace app on the Favorites screen.

Users can organize their applications into folders using the Citrix Workspace app desktop.

Applications are placed in the Start menu or the Applications folder on the user’s device, depending on the Citrix Workspace app version and operating system.

Therefore, the correct answer is B and D.

1: Configure user access

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.

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:

Application Lingering allows applications to stay open for a configurable amount of time after a user closes them, which can reduce application launch times in subsequent sessions.

 When creating a custom scope, the Full Administrator role is not available because custom scopes are designed to limit administrators’ permissions to specific objects or tasks within the Citrix environment.

According to the Create machine catalogs document from Citrix Virtual Apps and Desktops 7 2308, MCS adds the machines to Active Directory, which creates unique identities. MCS creates the number of VMs specified in the wizard, with two disks defined for each VM. In addition to the two disks per VM, a master is also stored in the same storage location. The identity disk is one of the two disks per VM, and it is used to store the Active Directory identity and other unique information for each VM. The identity disk is 16 MB in size and is created for each VM regardless of the disk type selected for the catalog.

According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course, team members who have access to their own admin partitions do NOT have Shell access by design. Shell access is only available for the default partition. Therefore, the team member cannot use aaad.debug or any other Shell commands from the CLI1

 According to the Reference Architecture: Image Management, Machine Creation Services (MCS) is a disk-based provisioning approach that works with major hypervisors and leading cloud platforms. The clones include a differencing disk and an identity disk linked from a base disk. MCS configures, starts, stops, and deletes virtual machines using the hypervisor APIs. When a Random/Non-Persistent desktop machine is restarted, the differencing disk will be updated from the base image, discarding any changes made by the user. This ensures that the desktop machine is always in a clean state and consistent with the master image.

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 architecture Layer is the following:

User: represent the endpoints

Access: represent the storefront and Citrix Gateway

Control: represent the delivery controller, database, studio, license, director

Resources: represent the VDAs

Host: represent the hardware, fiscal server, storage, network, etc.

 The New-BrokerRebootScheduleV2 cmdlet creates a new reboot schedule for a machine catalog or a delivery group. The -StartTime parameter specifies the start time of the reboot schedule in 24-hour format. The -RebootDuration parameter specifies the time interval in minutes between each machine reboot. The -Frequency parameter specifies how often the reboot schedule occurs. The -DesktopGroupName parameter specifies the name of the delivery group to apply the reboot schedule to. The -Enabled parameter specifies whether the reboot schedule is enabled or not12

 CDF Control is a tool that can be used to collect information to investigate issues with session performance. CDF Control allows the administrator to enable and disable tracing, collect trace logs, and analyze them using Citrix Scout or Citrix Insight Services

 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

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 Manage | Citrix Virtual Apps and Desktops 7 2308 document, the order of evaluation of rewrite policies is determined by the following factors:

The priority of the policy. A lower number indicates a higher priority.

The bind point of the policy. A global policy has a lower priority than a policy bound to a specific virtual server.

The type of the policy. A request policy has a higher priority than a response policy.

In this scenario, the policies are all bound to the same virtual server and have the same type (response). Therefore, the order of evaluation is based on the priority of the policy. The policy with the lowest priority number (POL_2) is evaluated first, followed by the policy with the next lowest priority number (POL_3), and so on. The policy with the highest priority number (POL_1) is evaluated last. Therefore, the correct answer is C.

 In general, to improve HDX session performance for high-latency, low bandwidth connections, administrators can configure settings that reduce the amount of data transferred and the resources required. This includes optimizing the visual experience (B, D, E) by adjusting the frame rate, color depth, and video quality.

 To ensure the line-of-business application is added to Favorites and users cannot remove it, the Citrix Administrator should add the phrase “KEYWORDS: Mandatory” to the application properties3.

According to the Citrix documentation, the Operator command policy grants full access to all features except shell access, user configuration, and partition configuration. The Sysadmin command policy grants full access to all features except shell access. The Network command policy grants full access to all features except shell access and user configuration. The Superuser command policy grants full access to all features, including shell access. Therefore, the Operator command policy is the best option for the scenario.

 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 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.

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.

HA Fail-safe mode is a feature that allows the Citrix ADCs to continue processing traffic even if both nodes become unavailable or fail a health check. This feature can be configured on each Citrix ADC independently, and it is recommended to enable it on both nodes for maximum availability. If HA Fail-safe mode is disabled on one node, that node will not process any traffic if it becomes unavailable or fails a health check, and it will not fail over to the other node. This could result in a loss of service for the business websites. Therefore, the correct answer is B.

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

Citrix Gateway can be hosted in Citrix Cloud or in a customer-controlled resource location. It provides secure remote access to Citrix Virtual Apps and Desktops service deployments.

 According to the Plan your StoreFront deployment document, for single server deployments you can install StoreFront on a non-domain-joined server but certain functionality will be unavailable; otherwise, StoreFront servers must reside either within the Active Directory domain containing your users’ accounts or within a domain that has a trust relationship with the user accounts domain unless you enable delegation of authentication to the Citrix Virtual Apps and Desktops sites or farms. All the StoreFront servers in a group must reside within the same domain. Therefore, server groups are not supported for non-domain-joined StoreFront servers (option D). Also, according to the User authentication document, when you configure a store, you specify the type of authentication service to use. By default, users are authenticated on StoreFront. Alternatively, you can delegate authentication to Citrix ADC or to the Delivery Controllers (option E). Authentication does not occur at the Domain Controller (option A) or at the Citrix ADC (option C) by default. Two-factor authentication is supported for non-domain-joined StoreFront servers (option B) as long as the authentication is delegated to Citrix ADC or Delivery Controllers.

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.

According to the Citrix Virtual Apps and Desktops 7 Administration On-Premises and in Citrix Cloud course, the Responder policy expression determines which requests are redirected by the Responder action. The expression http.REQ.URL.EQ(“/”) matches only the requests for the root page, and not any other pages. This prevents the redirection loop that occurs when the Responder action expression is also the root page. The other options are incorrect because they either match all requests or none.
