1Y0-204 Exam Dumps - Citrix Virtual Apps and Desktops 7 Administration

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 documentation1, the No-Monitor option allows the administrator to remove health checks from specific bound services. This option is useful when the administrator wants to reduce the number of health checks sent to the backend resources, or when the administrator knows that a particular service is always up and does not need to be monitored.

 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.

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.

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

Citrix Profile Streaming is a feature that, when enabled, allows profile files and folders to be fetched from the user store to the local computer only when users access them after logon. Registry entries and files in the pending area are fetched immediately. By default, profile streaming is disabled23.

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

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.

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.

According to the Citrix documentation1, burst capacity allows an instance to use more bandwidth than its dedicated bandwidth when there is spare bandwidth available on the SDX appliance. The priority parameter determines which instance gets the spare bandwidth first. A higher priority value indicates a higher priority. Therefore, the administrator can configure burst capacity of 1GB with priority 10 on the instance that requires more bandwidth, to meet traffic requirements.

This command enables the Delivery Controllers to trust requests sent to the XML service port. This is required for securing communication between StoreFront and the Delivery Controllers

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 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 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 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.

According to the Citrix documentation, when configuring a high availability pair, the administrator can set the primary node to STAY PRIMARY and the secondary node to STAY SECONDARY to prevent the configuration from being overwritten by the other node. Additionally, the administrator should enable HA monitoring on all the interfaces of both nodes to ensure that the HA status is updated correctly. Therefore, the correct answer is C and D.

According to the Citrix documentation1, the correct syntax for a rewrite action to change the HTTP version in a request is:

add rewrite action replace http.req.version “”

The new version should be enclosed in double quotes. Therefore, the correct answer is D, which uses the following command:

add rewrite action RW_ACT replace http.req.version “"HTTP/1.0"”

The other options are incorrect because they either use the wrong target location (http.res.version), the wrong value format (without double quotes), or the wrong action type (respond).

 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.

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.

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.

According to the Citrix documentation, when you bind an interface to a VLAN, the native VLAN of the interface changes to the VLAN to which it is bound. In this scenario, the native VLAN of interface 1/1 was 40 before the command was executed, so it remains 40 after the command is executed. The command does not change the native VLAN of the interface, only the VLAN to which it is bound. Therefore, the correct answer is B.

 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 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.

 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.

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 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 Citrix documentation1, the correct syntax for adding a simple ACL rule is:

add simpleacl -srcIP [-destIP ] [-TTL ]

The correct syntax for adding an extended ACL rule is:

add ns acl -srcIP [-destIP ] [-TTL ]

Therefore, the correct answer is B, because it uses the extended ACL rule format and specifies the destination IP address of the load balancing virtual server (192.168.100.25) and the TTL value of 10 minutes (600 seconds).

 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

 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

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 Citrix Health Assistant is a tool designed to troubleshoot and resolve common issues with Virtual Delivery Agent (VDA) registration, including event ID 1022.

 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.

Workspace Control allows users to reconnect to their disconnected sessions automatically when they roam between devices or reconnect after a network disruption. It is designed to provide a seamless user experience by maintaining the user’s session state, allowing them to pick up where they left off without starting a new session. This feature can be managed within the Citrix Virtual Apps and Desktops management consoles and is essential for scenarios where users need to maintain continuity in their work, such as in the given scenario where users leave work and expect to reconnect to their sessions later.

According to the Citrix documentation, the command bind cs vserver MYVPN_http -lbvserver Vserver-CS-1 binds a load balancing virtual server to a content switching virtual server. This means that the content switching virtual server will forward the requests that match its policies to the load balancing virtual server. In this case, the content switching virtual server MYVPN_http has a policy that matches requests for http://server.citrix.lab, so it will forward those requests to the load balancing virtual server Vserver-CS-1. Therefore, the users trying to access http://server.citrix.lab will be connected to the Vserver MYVPN_http, which will then connect them to Vserver-CS-1.

 According to the IBM documentation1, the Corrupt qualifier is used to modify the HTTP header of an HTTP request. The Corrupt qualifier changes the current value to a different value for a request or response header. If a value exists for the header, then this value is changed equivalent to a regular expression search and replace.

According to the Citrix documentation1, an HTTP-ECV monitor can be used to check the availability of a web server by sending an HTTP request and expecting a specific keyword in the response. The keyword can be specified in the Special Parameters - Receive String field. This monitor can ensure that the web server is not only responding, but also delivering the expected content.

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.

Virtual MAC is a feature that allows the Citrix ADC to use the same MAC address for the primary and secondary nodes in an HA pair. This way, the upstream router does not need to update its ARP table when a failover occurs. This feature can be enabled or disabled using the command set ha node -hamac yes|no or the GUI1

1: Citrix ADC High Availability (HA) - Citrix Docs

 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 modeand 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.

https://docs.citrix.com/en-us/citrix-adc/current-release/ssl/how-to-articles/create-and-use-ssl-certificates-on-a-citrix-adc-appliance.html

According to the Default policy settings document for Citrix Virtual Apps and Desktops 7 2308, the default compression policies are stored in the site database and are applied to the VDAs when they register with the broker or when a user connects to them. To use the default compression policies, a Citrix administrator needs to bind them to the virtual server that handles the ICA traffic. This can be done using the Web Studio console or the Local Group Policy Editor. The other options are not related to the default compression policies.

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 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.

 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 service documentation1, the Citrix Virtual Apps and Desktops service allows administrators to manage on-premises resources from the cloud, while providing users with secure access to those resources from any device. The Citrix Gateway service2 provides secure remote access to the on-premises resources through the Citrix Cloud Connector. The Citrix Provisioning service3 enables administrators to stream a single desktop image to multiple virtual machines, reducing storage and maintenance costs.

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.

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 allfeatures 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.

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:
