1Y0-204 Practice Exam Questions with Answers Citrix Virtual Apps and Desktops 7 Administration exam Certification

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.

Machine Creation Services (MCS) is suitable for deploying a large number of virtual desktops with low impact on network infrastructure. MCS allows for user-installed applications and persistency by using differencing disks and personal vDisks.

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.

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.

 MAC-based forwarding (MBF) can be used to avoid multiple route/ARP lookups and to avoid asymmetrical packet flows. MBF caches the MAC address of the upstream router that forwarded the client request to the appliance. When a reply is received, it is passed through to the same router that sent the client request without going through any route lookup

 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

Gateway Insight provides information about user authentication failures, such as the failure reason, the time of failure, and the number of failures1. It also shows the list of users who faced authentication failures and the authentication type they used2.

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 documentation, the Citrix Cloud Connector is a Citrix component that serves as a channel for communication between Citrix Cloud and the resource locations, enabling cloud management without requiring any complex networking or infrastructure configuration. This removes all the hassle of managing delivery infrastructure. The Cloud Connector also provides services for the Citrix Cloud Delivery Controllers to configure the resource location where Citrix Provisioning runs. Therefore, the administrator needs to install Citrix Cloud Connectors on the Citrix Provisioning servers to migrate the Citrix Provisioning environment to Citrix Cloud1

 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.

 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.

 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 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, 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.

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.

The ns_allow expression always evaluates to true, which means it allows all users access through the vServer. The ns_disallow and ns_false expressions always evaluate to false, which means they deny all users access. The ns_true expression is not a valid policy expression1

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 Virtual Apps and Desktops 7 Deployment and Administration course, the Generate Support File option on the Citrix ADC appliance allows the administrator to collect logs and configuration information for troubleshooting purposes. The support file can be downloaded and sent to the Citrix Support Engineer for analysis. The other options are not relevant for this scenario.

 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 course, page 14 of Module 1: Architecture Overview, “Layer 3 mode is the default mode of operation for a Citrix ADC appliance. In this mode, the appliance acts as a router and routes packets based on the destination IP address.” Therefore, if the Citrix ADC receives packets that are destined for a MAC address owned by the Citrix ADC, but the destination IP address does not belong to the Citrix ADC, it will route the packets based on the destination IP address.

According to the Citrix documentation1, the weight option assigns a numerical weight to a service. The higher the weight, the more requests the service can handle. By default, the weight is 1, which means equal distribution of requests. To make the new servers receive twice the connections of the old servers, the administrator needs to assign a weight of 2 to the services attached to the new servers.

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.

 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.

When using an HDX Session printers policy, print jobs sent to a printer managed by the print server are routed directly to the network print server and then to the specified printer3.

A SSL profile is a collection of SSL settings that define the SSL behavior of a virtual server. A Citrix Administrator can use SSL profiles to apply the same SSL settings to multiple SSL virtual servers, which simplifies the configuration and management of SSL parameters1.

1: SSL Profiles

 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 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.

 To enable Azure AD authentication for the Workspace Experience, the administrator needs to enable Azure AD authentication under Workspace Configuration in Citrix Cloud and add Azure AD Account under Identity Providers in Citrix Cloud. This allows users to authenticate using their Azure AD credentials to access their applications and desktops through the Workspace Experience. The Cloud Connectors are not directly involved in the Azure AD authentication process for Workspace Experience12.

To get application enumeration working in a Citrix Cloud migration scenario with on-premises StoreFront and Citrix ADC, the administrator needs to add the Citrix Cloud Connectors as Secure Ticket Authority (STA) servers on both Citrix ADC and StoreFront12.

The Citrix Application Delivery Management appliance, when used with Citrix Director, allows administrators to monitor various aspects of the infrastructure. It provides detailed insights into latency and bandwidth effects for specific user sessions ©, average ICA round trip time for specific user sessions (D), and peak concurrent total sessions for specific applications and desktops (E), enhancing the ability to manage and optimize the Citrix environment.

The Citrix Gateway Universal License is an add-on license that allows VPN connections to the network from the Citrix Secure Access client, a SmartAccess log on point, or Secure Hub, Secure Web, or Secure Mail1. The other licenses are not suitable for this scenario, as they either do not support VPN access or have limited user capacity. For more information about Citrix Gateway licensing, see Licensing Models - Citrix and NetScaler Gateway licensing.

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 Secure Web Gateway 12.1 documentation1, Citrix Secure Web Gateway (SWG) is a cloud-delivered service that provides secure access to web and SaaS applications, globally. It provides a complete stack of security capabilities, such as Secure Web Gateway, Cloud Access Security Broker, Malware Protection with Sandboxing, Intrusion Prevention and Detection Systems, and Data Loss Prevention. Citrix SWG can intercept and inspect all the traffic, including SSL/TLS, coming in and going out of the enterprise network. It can also block access to URLs identified as serving harmful or insecure content, and identify users who are accessing malicious websites. Citrix SWG can be deployed as a proxy on a Citrix ADC appliance at the edge of the network. The other options are not relevant for this scenario, as they do not provide the same level of security and visibility as Citrix SWG.

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

 According to the screenshot, the CS policy CS1_Pol has a rule that matches the HTTP request http://xenapp.training.lab/url1, since it contains “/url1/” in the URI path. This policy is bound to the CS vServer CS_LB_HTTP with a priority of 100, which means it has a higher precedence than the CS policy CS2_Pol, which has a priority of 110.  Therefore, the request will be redirected to the target LB vServer specified by CS1_Pol, which is LB_vserver1

According to the Citrix Virtual Apps and Desktops service on Citrix Cloud documentation, the control layer is always managed by Citrix when hosting Citrix Virtual Apps and Desktops on the Citrix Cloud platform. The control layer consists of the Citrix Cloud Connector, Studio, Director, and other components that orchestrate the delivery of applications and desktops. The resource layer, which contains the VDAs, hypervisors, and storage, is managed by the customer or a service provider. The user layer, which contains the user profiles, policies, and data, is also managed by the customer or a service provider. The access layer, which contains the StoreFront and NetScaler Gateway components, can be either managed by Citrix or the customer, depending on the deployment scenario.

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 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 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.

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.

 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 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.

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

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 “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.

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.
