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

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 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 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.

 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.

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.

 Profile streaming ensures that only the files and folders that a user needs are downloaded to the VDA during logon and logoff. This reduces logon and logoff times and allows users to access their profiles in the event of network interruptions or VDA failures1

1: https://docs.citrix.com/en-us/profile-management/current-release/configure/profile-streaming.html

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 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.

To enable Citrix XML Service trust for user access within a Citrix Virtual Apps and Desktops infrastructure, the administrator must run the Set-BrokerSite -TrustRequestsSentToTheXMLServicePort $true PowerShell command from within a Controller. This configures the site to trust requests sent to the XML Service port1.

LACP allows multiple network interfaces to be bundled together to form a single logical channel. This can increase the bandwidth and availability of the Citrix ADC1

 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 documentation, the -denySSLReneg parameter specifies the type of SSL renegotiation that the Citrix ADC denies. The possible options are:

NONSECURE: Deny renegotiation requests from a client if the initial handshake between the Citrix ADC and the client is not secure. A secure handshake is one in which both parties prove their identities to each other by presenting valid certificates.

FRONTEND_CLIENT: Deny renegotiation requests from a client on a front-end SSL connection, regardless of whether the initial handshake is secure or not. A front-end SSL connection is one in which the Citrix ADC communicates with the client over SSL.

ALL: Deny all renegotiation requests from a client on a front-end SSL connection and from a server on a back-end SSL connection. A back-end SSL connection is one in which the Citrix ADC communicates with the server over SSL.

NO: Allow all renegotiation requests.

Therefore, the correct answer is A and C.

 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

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.

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

 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.

According to the Proxy modes | Citrix Secure Web Gateway 12.1 - NetScaler document, to configure a Content Switching virtual server for implementing the Citrix Secure Web Gateway in the transparent proxy mode, the command should be:

add cs vserver < name > PROXY < ipaddress > < port >

The document also provides an example of the command:

add cs vserver swgVS PROXY 192.168.10.1 80

Therefore, the correct answer is C, which matches the format and the example given in the document. The other options are incorrect because they either use asterisks (*) instead of an IP address, or they do not specify a port number.

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 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 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.

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 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

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.

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.

 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 Cloud documentation1, a Citrix Administrator needs to supply the following information when creating a silent installation of the Cloud Connector:

The customer ID of the Citrix Cloud account for which the administrator is installing the Cloud Connector.

The client ID and secret of the secure API client the administrator wants to use to install the Cloud Connector.

The resource location ID for the resource location that the administrator wants to associate with the Cloud Connector. If the administrator does not supply this value, Citrix Cloud uses the ID of the default resource location.

Therefore, the correct answer is C, Resource Location ID.

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

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.

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.

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:

 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 Get-BrokerSite PowerShell command retrieves information about the site, including the name of the deployment, the local host cache configuration, and the license level. This command is part of the Citrix Virtual Apps and Desktops 7 Administration toolkit and is used to manage various aspects of the site configuration.

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.

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

 If client drives are not mapped in a HDX session despite the ‘Auto connect client drives’ setting being configured, it could be due to the absence of loopback processing. Enabling loopback processing in the Group Policy Object (GPO) allows user-specific settings to be applied regardless of where the user object is located in Active Directory, ensuring that the policy is effectively applied to the published desktops.

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.

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 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.

Inline CSS is a FEO action that replaces external CSS files with inline CSS code in the HTML document. This reduces the number of HTTP requests and improves the page load time. The screenshots show that the HTML code in the second snippet has no external CSS file linked, unlike the first snippet. Therefore, the correct answer is B. Inline CSS12.

Some additional information:

FEO stands for Front-End Optimization, which is a feature of Citrix Application Delivery Management (ADM) that optimizes web pages for faster delivery and better user experience3.

FEO actions are rules that modify the HTML, CSS, JavaScript, and images of a web page to improve its performance. FEO actions can be applied globally or to specific web pages based on policies4.

Other FEO actions include Truncate CSS, which removes unused CSS selectors and properties; Move CSS to head, which moves the CSS code to the head section of the HTML document; and Rearrange CSS, which reorders the CSS code to avoid rendering delays4.

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 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 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.

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.

The Control layer contains the Site database in a Citrix Virtual Apps and Desktops Architecture model. The Site database stores the running site configuration, plus the current session state and connection information. The Access layer contains the components that users need to connect to their apps and desktops, such as StoreFront and Citrix Gateway. The User layer contains the user profiles, policies, and data. The Resource layer contains the machines that host the apps and desktops, such as VDAs and hypervisors

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.

 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
