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

According to the Citrix documentation1, the triggerMonitor parameter specifies the conditions under which the service monitor is invoked. The possible values are:

ALWAYS: The service monitor is always invoked.

MEPDOWN: The service monitor is invoked only when Metric Exchange Protocol (MEP) has marked the service as DOWN for any reason.

MEPSUSPECT: The service monitor is invoked only when MEP has marked the service as SUSPECT.

NONE: The service monitor is never invoked.

Therefore, the command set gslb site SiteB –triggerMonitor MEPDOWN will set the triggerMonitor value to MEPDOWN for SiteB, which means the service monitor is invoked only when MEP has marked the service as DOWN for any reason.

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.

Pass-through from NetScaler Gateway is the authentication method that allows external users to access internal resources through StoreFront without having to enter their credentials again. This method requires that users authenticate on NetScaler Gateway, which then passes the user identity to StoreFront. This option is only available if it has been enabled for the store. See Pass-through from Citrix Gateway for more details.

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.

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.

According to the Citrix documentation1, when connection proxy is used as the site persistence method, the Subnet IP (SNIP) address of the appliance is used to source the traffic when the connection is proxied. This ensures that the response from the server goes back to the same appliance that proxied the request.

 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.

 The administrator should negate the expression of the Responder policy to avoid the HTTP callout recursion issue. According to the Citrix documentation, “If you configure an HTTP callout policy that is bound globally, you must ensure that the policy expression does not match the callout request. Otherwise, the callout request will trigger the policy, resulting in a callout recursion.” The expression in option B ensures that the policy does not match the callout request by adding the NOT operator at the end.

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

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

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.

 To allocate the Citrix Virtual Desktops license file from the Citrix.com account, a Citrix Administrator needs the hostname of the Citrix License Server. The hostname is case sensitive and must match the name entered in the Citrix Licensing Manager or the License Server Console

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

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.

Typically, the migration of existing profiles to a new profile management system occurs during the user’s first logon after the policy has been applied, as this is when the user’s profile is first accessed and can be migrated.

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 Policies page of Citrix Virtual Apps and Desktops 7 2308 documentation, Classic policies are a collection of settings that define how sessions, bandwidth, and security are managed for a group of users, devices, or connection types. You can apply policy settings to physical and virtual machines or to users. Classic policies can be filtered by various criteria, such as HTTP, IP, and TCP. These are the only options allowed when using Classic policies. Other options, such as CLIENT, SERVER, and DNS, are not valid filters for Classic policies.

The Applications and Trends features within Citrix Director can be used to view historical resource utilization for a machine running the VDA. The Applications feature shows the application usage and resource consumption of each application on a specific machine2. The Trends feature shows the historical trends of various metrics such as CPU, memory, disk, and network utilization for a specific machine3.

 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 (CWS-215) course, the LeastConnection method is used to redirect user requests to the data center with the fewest active connections. This can help balance the load across different data centers and improve the user experience. The other methods are not suitable for this scenario because they do not consider the number of active connections or the location of the user

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

The Help Desk Administrator role is suitable for managing user sessions and power-managing machines within the Delivery Group without the ability to create new objects23.

 According to the Citrix documentation1, “Cloud Connectors are the communication channel between your resource location and Citrix Cloud. They enable cloud management without requiring any complex networking or infrastructure configuration such as VPNs or IPsec tunnels. Resource locations contain the resources you want to make available to your subscribers, such as applications and desktops. Each resource location requires at least one Cloud Connector to communicate with Citrix Cloud.” Therefore, the VDA machines should communicate with a Cloud Connector that is located in the on-premises location in order to become registered with the Site.

1: Cloud Connector Technical Details

https://docs.citrix.com/en-us/citrix-virtual-apps-desktops-service.html

Citrix Cloud Connector requires the machine to be joined to a domain as part of its prerequisites for installation. If the machine is not domain-joined, it could prevent the Cloud Connector from installing properly. This is because Cloud Connector needs to communicate with Citrix Cloud services and typically relies on domain credentials for authentication and other functions within a domain environment.

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.

Site-level GPOs are processed first for a Citrix Virtual Apps and Desktops Site, followed by domain-level GPOs, Citrix local-Site policies, and OU level GPOs. This is the policy processing order and precedence for Citrix policies, as described in the Work with policies article from the Citrix Virtual Apps and Desktops 7 2308 documentation.

The Logon Performance report in Citrix Director provides insights into the various stages of the logon process and can help identify which stage is causing the delay. It includes details such as Brokering, VM Start, HDX Connection, Authentication, and Interactive Session times, allowing administrators to pinpoint the bottleneck in the logon process.

 According to the Citrix documentation1, nslog is a log that records detailed information such as statistics, metrics and debug information on the Citrix ADC in a proprietary binary format. Nstrace is a log that captures network traffic on the Citrix ADC in a standard pcap format. Syslog is a log that records system events and messages on the Citrix ADC in a standard text format. Nsconfig is a file that contains the configuration settings of the Citrix ADC.

 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

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.

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.

The redirectURL parameter of the set cs vserver command specifies the URL where the user requests are redirected if the status of the content switching virtual server is DOWN1. This parameter is used for configuring backup servers or displaying maintenance messages1.

Citrix Virtual Apps and Desktops support several high availability solutions for on-premises deployments, including Always On Availability Groups, SQL Server database mirroring, and SQL clustering. These features ensure automatic failover and continuous operation1

The NSIP address is the NetScaler-owned IP address that uniquely identifies the NetScaler on your network, and it provides access to the appliance. By default, the NSIP is the source IP address for packets originating from the NetScaler appliance, such as packets destined for NTP servers1.

The “Limit Visibility” option allows a Citrix Administrator to hide a published application on Citrix Workspace app for specified users or groups within a delivery group. This option can be configured in the application properties in Citrix Studio123 or using PowerShell commands4. This option does not affect the other choices.

The Citrix Virtual Apps and Desktops documentation specifies that the Local Host Cache feature allows connection brokering operations in a site to continue when the connection between a Delivery Controller and the site database fails1. This implies that the Delivery Controller, which is part of the FlexCast Management Architecture (FMA) services, uses the Local System account to access the Citrix Virtual Apps and Desktops SQL databases in scenarios where the primary database connection is unavailable.

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.

https://docs.citrix.com/en-us/citrix-adc/13/ssl/ssl-offload-howto.html

 According to the Local Host Cache documentation, when the Site database is inaccessible for 90 seconds, the principal broker (Citrix Broker Service) on a Delivery Controller switches to the Local Host Cache mode and uses its local database to broker new sessions. The other Delivery Controllers in the Site do not broker any sessions during the outage. Therefore, option A is the correct answer.

The administrator needs to change the product edition in Citrix Studio to match the newly installed advanced licenses. This action ensures that the Citrix Virtual Desktops Site utilizes the correct licenses and resolves the issue with the evaluation license expiration error message.

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 identity disk is a small disk attached to each virtual machine that stores the unique information for that machine, such as computer name, IP address, and Active Directory account. This disk is created when using Machine Creation Services with the Desktop Experience set to ‘Random’.1

 To view license information in Studio, an administrator must have at least the Read Licensing delegated administration permission. The built-in Full Administrator and Read-Only Administrator roles have that permission1.

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.

Citrix Director is a web-based monitoring and troubleshooting console for Citrix Virtual Apps and Desktops that allows administrators to control and monitor virtual applications and desktops1. Director can access real-time data from the Broker Agent and historical data stored in the Monitor database to provide information on the state of the Citrix infrastructure1. Director can also display failures in real time, providing a better idea of what the end users are experiencing1. Therefore, Director is the best tool to review the state of the Citrix infrastructure from a single location.

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

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

 According to the Citrix documentation, the cacheForSecs parameter of the set httpcallout command specifies the time, in seconds, for which the response from the HTTP callout server is cached. Therefore, the effect of the command is to set the cache duration of the HTTP callout response to 120 seconds.

 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.
