Citrix Xen Desktop Interview Questions
Question 19. How Does A Window Print Server Work?

Answer :

Normally, a server working machine is mounted at the print server pc and then the office’s various printers may be introduced to the device with the suitable drivers. The new printers are then set up to be shared from the print server, in order that personnel can get right of entry to them from their person workstations.

Question 20. What Is Print Spooling?

Answer :

In print spooling, files are loaded right into a buffer (typically an area on a disk), and then the printer pulls them off the buffer at its personal rate. Because the files are in a buffer in which they can be accessed by the printer, you could carry out other operations on the laptop even as the printing takes place within the historical past. Spooling additionally helps you to place some of print jobs on a queue in preference to anticipating every one to finish before specifying the following one.

Question 21. What Is Windows Universal Print Driver?

Answer :

(Universal Printer Driver or Unidriver) is a GDI-based Microsoft Windows everyday printer motive force and structure for non-PostScript printers. It is used to simplify motive force development of non-PostScript printers (additionally known as Winprinters) for printer manufacturers. Unidrv lets in the introduction of a printer-particular minidriver inside the form of a GPD (Generic Printer Description) record, much like a PPD file, that's a whole lot easier than kernel mode driving force development.

Question 22. What Is A Xps And Emf Print Drivers?

Answer :

Universal XPS Printer driving force:-

This driver is primarily based on the Windows XML Paper Specification (XPS) printing era delivered in Windows Server 2008. Windows XPS printing technology makes use of XML to create a platform-independent “electronic paper” similar to Adobe’s PDF layout. The XPS format is a tool-unbiased XML-based spool file format that offers a compressed XML description of a web page’s photograph factors. Printing gadgets can use XPS-formatted print jobs without delay with out translation.

The Citrix Universal XPS Printer driver creates the XPS print process the usage of the Microsoft XPS printer driver at the patron tool. The Citrix Universal XPS Printer driver obtains printing tool-specific statistics from the customer device. Provided your farm servers are jogging XenApp five.0 and your client devices have .NET three.Zero installed on them, which comes with Windows

Vista, you could use the Citrix Universal XPS Printer motive force.

Citrix Universal Printer driver:-

This driving force uses Windows’ Enhanced Metafile Format (EMF) generation.EMF is a device-unbiased format for capturing the graphical elements revealed on each page of a print process. A purchaser-side renderer makes use of EMF and presents a considerable reduction within the processing time of Citrix Universal print jobs at the customer.

Question 23. Rdp V/s Xenapp?

Answer :

Maine diffrence – RDP: transfer entire body and bandwidth depends on display screen resolution,

ICA: create digital channels(video,audio,print,keyboard& mouse updates) and transfers only screen updates and bandwidth will much less as keyboard and mouse click on might be 10-15% of frame

RDP works handiest beneath TCP/IP, whilst ICA works on many protocols.
RDP doesn’t permit packages to run in a browser, at the same time as works for ICA
Session Reliability might be there in ICA,it isn't always inside the RDP
Encryption is possible in ICA,it is not present in RDP
ICA additionally helps non home windows like DOS, UNIX, MACOS, mobiles
Question 24. What Is The Difference B/w Data Store And Dc?

Answer :

Datastore – Is the database which contain the static facts associated Xenapp farm which incorporates – published packages, users, printers, and servers, citrix GPO.

Datacollector – continues dynamic facts about the servers in the region, together with server masses, consultation popularity, published packages, customers connected, and license utilization. Data creditors receive incremental records updates and queries from servers inside the zone. Data collectors relay information to all different statistics collectors inside the farm. By default, the information collector is configured on the first server when you create the farm, and all different servers configured with the controller server mode have same rights to become the records collector if the facts collector fails. When the zone’s statistics collector fails, a statistics collector election occurs and another server takes over the statistics collector functionality. Farms decide the information collector primarily based on the election alternatives set for a server. Applications are usually no longer published at the facts collector.

Question 25. What Is Xml Broker?

Answer :

It features as an middleman among the farm and Web Interface.
XML Broker receives the credentials of consumer from the Web Interface.
XML Broker retrieves the applications which have person permissions to get right of entry to.
This is carried out by using Independent Management Architecture and returns to the Web Interface.
Once the user is authenticated, the XML broker locates the server within the farm.
XML Broker returns the cope with of the carrier rendering server to the Web Interface.
XMS Service features among Web Interface and IMA carrier.
Question 26. What Is Citrix Xenapp Farm?

Answer :

XenApp server farm is a logical series or institution of XenApp servers that can be controlled as a single entity and they talk to unmarried datastore server.

Question 27. What Is Zone?

Answer :

A sector is a grouping of XenApp servers that communicate with a common statistics collector. In large farms with a couple of zones, each region has a server certain as its data collector. Data creditors in farms with more than one region function as communique gateways with the alternative sector facts creditors. The information collector keeps all load and session records for the servers in its sector. All farms have at the least one quarter, even small ones. The fewest wide variety of zones have to be implemented, with one being highest quality. Multiple zones are necessary handiest in big farms that span WANs.

Session reliability – 2598/2599.

License – 27000.

Vendor daemon – 7279.

License management console – 8082.

Database port – 1433.

IMA – 2512 & 2513

Question 29. What Is Application Enumeration Process?

Answer :

The application listing and displaying process is as follows:

A user launches the Web Interface URL, it returns the logon web page.
Users types their credentials, it is forwarded from XML then to IMA service in HTTP (or HTTPS) form.
The IMA then forwards thecredential statistics to local Lsass.Exe (lsass.Exe” is the Local Security Authentication Server. It verifies the validity of user logons for your PC or server).
The Lsass.Exe encrypts the credentials then passes them to the domain controller.
The DC returns the SIDs (consumer’s SID and the listing of organization SIDs) to Lsass.Exe and to IMA.
IMA used the SIDs to search the Local Host Cache (LHC) for a listing of programs and the Worker Group Preference policy for that authenticated user.
The list of the programs collectively with the consumer’s worker organization desire coverage are returned to the Web Interface.
The Web Interface returns the internet page to the web browser with the list of programs
Web Interface passes the application facts together with the user’s Worker Group Preference coverage again to IMA on the XML dealer server.
It then forwards to the IMA carrier on the Zone Data Collector.
The Zone Data Collector attempts to find out a least loaded server consistent with the Worker Group desire list.
When it unearths the least loaded server, it sends a query to the Citrix Service Manager of that server to verify whether or not the server has the required utility established, if the solution is sure, it then gives this server’s host ID to the XML broker.
The XML broking interprets this host ID into it’s IP deal with by using looking the LHC
The IP cope with is then provided to Web Interface and it creates the ICA file.
The ICA record is then lower back to Web browser on the customer device.
Citrix on-line Web plug-in uses the ICA document to launch an ICA connection to the least loaded XenApp server.
The XenApp server launches the application for the person.
Question 30. What If Datastore Goes Down?

Answer :

Data save Server is going down (And you've got a backup from the Data keep available, If you don’t you would should recreate all the farm settings) dsmaint backup takes a backup of the facts keep.
Run a dsmaint migrate emigrate the settings to a new statistics save. Even if a Data keep is unavailable the LHC consists of sufficient data about the farm to allow ordinary operations for an indefinite time period. However, no new facts can be posted, or introduced to the farm, until the farm facts shop is on-line. If you need to start from scratch with a new records store, prepare a brand new statistics store the way you probably did earlier than configuring XenApp and run the Server Configuration Tool from any farm server. After jogging the Server Configuration Tool, manually reenter the misplaced settings. If you operate the equal call as he preceding records shop, you do no longer want to reconfigure the farm servers.
Question 31. What If License Server Goes Down?

Answer :

The Citrix servers can function with out contacting the license server and it's far 30-days fault tolerant, and in Enterprise model an alert may be set with Resource Manager to ship an email in case of License Server Connection Failure. If the license server reconnects at any time inside the thirty days the problem resolves itself. If the server is not going to come back lower back up, then the license record, digitally signed with the case-sensitive hostname of the old license server, is the vital component. The license record, a *.Lic document, can be backed as much as a thumb force one at a time, and restored to a brand new server with the same call of the vintage license server, and the Citrix License server software program hooked up.

Question 32. What If Data Collector Goes Down?

Answer :

Data collector server goes down.
The servers in the region apprehend that the records collector has long past down and start the election manner. In this example the again up information collector is elected as the new facts collector for the quarter.
The member servers inside the area then ship all in their data to the brand new information collector for the sector. This is a feature of the range each server has of sessions, disconnected consultation, and packages.
In flip, the brand new facts collector replicates this records to all other statistics collectors inside the farm. Even if a Data collector is unavailable the servers will hold to characteristic. The users which are already logged in will no longer be affected.
Question 33. What Happens In Zdc Election Process?

Answer :

Incase ZDC is not be available, some other server within the zone can take over that role. The method of taking the position is known as ZDC election. Server Administrators ought to pick the Zone Data Collector approach carefully during the farm design itself. When an election wishes to occur in a zone, the winner of the election is decided by way of

Highest model of Presentation Server first
Highest rank (as configured inside the Management Console)
Highest Host ID number (Every server has a completely unique ID known as Host ID).
When the present statistics collector for Zone failed abruptly or the communication among a member server and the Zone Data Collector for its zone failed or the communique among records creditors failed, then the election manner starts offevolved in the Zone. If the server is shutdown nicely, it triggers the election manner before it goes down. The servers in the region recognize the facts collector has long past down and starts offevolved the election technique. Then the ZDC is elected and the member servers ship all of their records to the new ZDC for the sector. In turn the brand new statistics collector replicates this records to all different records creditors within the farm.

Note: The facts collector election system is not depending on the information keep. If the facts collector goes down, sessions related to other servers inside the farm are unaffected .The facts collector election technique is induced robotically without administrative interference. Existing in addition to incoming customers are not stricken by the election procedure, as a brand new records collector is elected nearly immediately.

C: QueryHR.Exe

—— Showing Hosts for “10.22.44.Zero” ——

Host 1:

—————————–

———————————

—— Show Host Records Completed ——-

To see the Host ID range and its version, run queryhr.Exe utility (with no parameters).

Each server within the area has a rank assigned to it. The administrator can configure such that the servers in a region can be ranked to make the server as the maximum preferred to serve as the quarter grasp or ZDC. The ties among servers with the equal administrative ranking are damaged via using the HOST IDs assigned to the servers. When a Presentation Server starts offevolved or whilst the IMA provider starts, the IMA service starts offevolved seeking to contact other servers thru the IMA protocol on port 2512 till it unearths one which’s online. When it unearths, it queries it to discover which server is performing because the information collector. The winner of this Zone Data Collector election is determined by the most recent model of the IMA service. We can manipulate which server will act as facts collector with the aid of keeping that server the most up to date.

Data Collection Election Priority

Whichever server has the maximum current model of the IMA Service running. (This can also include hotfixes) and the server with the best desire set inside the information shop.

Basically facts collectors and information store aren't virtually associated. The facts shop holds permanent farm configuration statistics in a database, and the records collector tracks dynamic consultation statistics in its RAM.

In addition to their number one function to provide dynamic farm information for admin consoles or for incoming connection requests, facts collectors additionally participate in the distribution of configuration adjustments to Presentation Servers inside the farm. When we make a changes in a presentation server that exchange is written to the local host cache of whichever server we connected to, after which immediately replicated to the records store. Presentation Server simplest looks for changes within the primary statistics shop each half-hour. Whenever a alternate is made to the records keep, that change is despatched to the information collector for the sector.

The records collector then distributes that change (thru IMA port 2512) to all the servers in its quarter, allowing each server to replace its own neighborhood host cache for that reason. Furthermore, if we've got more than one area, the initial records collector contacts the statistics creditors inside the other zones. It sends its trade to them, and in turn those information collectors ahead the exchange to all of the servers of their zones.

Coolest element is if the exchange is greater than 64k, the statistics collectors don’t send the real change out to its zone. Instead they send out a notification which reasons the servers inside the quarter to carry out an “on demand” sync with the primary statistics save. However it’s rare for a unmarried exchange to be extra than 64k in length.  The facts collector election priority settings in the control console

Presentation Server Java Management Console > Right-click on on farm

call >Properties > Zones > spotlight server > “Set Election Preference”

We can absolutely control which server is our records collector by using manually putting the preferences inside the Java console. We can manually configure four tiers of Zone’s Data Collector election preferenceoptions

Most Preferred

Preferred

Default Preferred

Not Preferred

The crucial component to consider is that these choices will beignored if a more moderen server is up for election.

Question 38. What Is Session Reliability?

Answer :

This placing allows or prevents classes to remain open throughout a loss of network connectivity. By default, session reliability is permitted.

Session Reliability continues classes active when network connectivity is interrupted. Users retain to see the software they are using until community connectivity resumes. When connectivity is momentarily misplaced, the consultation stays lively on the server. The person’s display freezes and the cursor adjustments to a spinning hourglass until connectivity resumes. The user keeps to get entry to the display throughout the interruption and may resume interacting with the software whilst the community connection is restored. Session Reliability reconnects customers without reauthentication activates.

Question 39. What Is Meant By Keep Alive?

Answer :

Keep Alive Policy Settings The Keep Alive segment incorporates policy settings for coping with ICA preserve-alive messages.  ICA maintain alive timeout This placing specifies the variety of seconds among successive ICAkeep-alive messages. By default, the c programming language between preserve-alive messages is 60 seconds.  Specify an interval between 1-3600 seconds wherein to ship ICA keep-alive messages. Do now not configure this placing if your network tracking software is answerable for closing inactive connections. If using Citrix Access Gateway, set preserve-alive periods on the Access Gateway to healthy the maintain-alive intervals on XenApp.

ICA maintain alives

This setting allows or disables sending ICA keep-alive messages periodically. By default, keep-alive messages aren't sent.

Enabling this putting prevents damaged connections from being disconnected. If XenApp detects no pastime, this placing prevents Remote Desktop Services from disconnecting the session. XenApp sends keep-alive messages each few seconds to locate if the consultation is active. If the session is now not lively, XenApp marks the session as disconnected.

ICA Keep-Alive does now not work in case you are the usage of Session Reliability.Configure ICA Keep-Alive best for connections that are not the usage of Session Reliability.

Question forty six. What Are Troubleshooting Steps If Ima Service Is Not Gettingstarted?

Answer :

The following could be some motives, similarly to others, for the

IMA Service to fail to begin:

IMA Service load time
IMA Service subsystem
Missing Temp listing
Print spooler service
ODBC configuration
Roaming Profile
Another server with an identical NetBIOS call on the identical community
IMA Service Load Time

If the Service Control Manager reviews that the IMA Service could not be began, but the provider in the end begins, forget about the error message. The Service Control Manager has a timeout of six mins. The IMA Service can take longer than six mins to begin if the weight on the database exceeds the competencies of the database hardware or if the community has excessive-latency. If you experience that the provider is simply hung(stuck in a “starting” kingdom) you can terminate the ImaSrv.Exe procedure in Task Manager and restart the Citrix Independent Management Architecture provider as a check.

IMA Service Subsystem

Examine the following Windows Registry setting:

x32-bit: HKEY_LOCAL_MACHINESOFTWARECitrixIMARuntimeCurrentlyLoadingPlugin
x64-bit: HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCitrixIMARuntimeCurrentlyLoadingPlugin
If there may be no value exact within the CurrentlyLoadingPlugin portion of the previous Windows Registry entry, then either the IMA Service couldn't connect with the facts keep or the nearby host cache is lacking or corrupt.

If a CurrentlyLoadingPlugin value is particular, the IMA Service made a connection to the records save and the value displayed is the call of the IMA Service subsystem that did not load.

Missing Temp Directory

If administrators see an “IMA Service Failed” error message with an errors code of 2147483649 when starting the server, the local system account is probably missing a Temp directory that's required for the IMA Service to run.

To benefit similarly insight into the scenario, change the IMA Service startup account to the neighborhood administrator and restart the server. If the IMA Service is a hit in beginning below the neighborhood administrator’s account, then it's far likely that a lacking Temp listing for the nearby system account is causing the scenario.

If the Temp listing isn't present, then manually create one as

Temp. For instance:

C:WindowsTemp

Also, verify that the TMP and TEMP machine environment variables factor to the transient listing. Restart the server to restart the IMA Service.

 Print Spooler Service

When the server tries to start the IMA Service, the “Setup Could Not Start the IMA Service” mistakes message seems. This mistakes shows that the IMA Service isn't beginning, probable due to the fact the print spooler service is not running or become configured incorrectly. In addition, the following mistakes messages appear in the Event Viewer:

Failed to load plugin MfPrintSs.Dll with blunders 80000001h
Failed to load initial plugins with mistakes 80000001h
The Independent Management Architecture service terminated with carrier-precise error
The mistakes takes place because the print spooler service:

Has stopped
Is disabled
Is now not configured to run under the Local System Account
To remedy this issue, confirm that the print spooler carrier became started inside the context of device as opposed to in the context of a consumer. A print spooler provider that is not strolling or has been configured incorrectly would possibly reason the printing subsystem to fail to load.

To clear up the scenario, stop and start the print spooler service, make sure that it's miles configured to run under the Local System Account.

Then, attempt to start the IMA Service.

ODBC Configuration

Verify that the Microsoft SQL Server or Oracle server is on-line.
Verify the name of the DSN report that the IMA Service is the use of the
following key inside the Windows Registry:

x32-bit: HKEY_LOCAL_MACHINESOFTWARECitrixIMADataSourceName
x64-bit: HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCitrixIMADataSourceNameRoaming Profile
three. Attempt to connect with the database using the DSN file with an ODBC test software inclusive of Oracle ODBC Test or SQL Server ODBC Test.
4. Verify that the best person call and password are being used for database connectivity.
5. Change the user name and password the use of the DSMAINT CONFIG command, if wished using dsmaint config /user:username /pwd:password/dsn:dsnfilename.
6. Enable ODBC Tracing for similarly troubleshooting.
 When the server attempts to begin the IMA Service, the “Setup Could Not Start the IMA Service” mistakes message appears. In the occasion viewer the error IMA_RESULT_INVALID_MESSAGE is displayed or other events related to the IMA Service no longer being able to start. Verify the dimensions of the roaming profile, in particular if it's far crossing a WAN. Also look ahead to error messages associated with no longer being capable of load the profile. Test with a local user profile or one this is smaller in size.

Another server with an same NetBIOS call on the equal community Verify that there isn't always another server at the community with the equal NetBIOS name at the network. If the CurrentlyLoadingPlugin has the ImaLicSs.Dll listed, this might be an illustration of this circumstance.Another symptom of ImaLicSs.Dll “106. The IMA Service did not begin because of license organization corruption in the records save. “CTX124406 – DSCHECK – XenApp Data Store Checker Tool Commands.

Question 47. What Is Proximity Printing?

Answer :

Proximity printing essentially detects a consumer’s present day IP address after which maps the user to a printer inside the user’s subnet. Granted, one might hope that perhaps every floor has its personal scope or some form of an identifier that could make it precise so that you can map a printer thus. Assuming that is the case, you can configure Citrix print guidelines to map network printers for customers based totally on the IP address of their tool.

To configure proximity printing, observe those steps:

Create a separate Citrix Policy for every subnet or each geographic region
Enable proximity printing via the consultation printing coverage rule in Citrix Policies
Add the printers for that subnet or geographic region within the coverage
Set the Default printer policy to use the Do not alter the user’s default printer placing
Filter the coverage bt Client IP address
Now there is every other technique that you need to be aware, called Workspace Control. This characteristic is beneficial while users disconnect from their existing session, pass to a one-of-a-kind area and a one of a kind device and join lower back to that identical session. Typically, without Workspace Control, if they resume the identical session the printers will now not trade. With Workspace Control, when they connect again, it mechanically detects that they may be connecting from a exceptional vicinity and a one-of-a-kind tool and maps their printers. Cool, no.

Answer :

CTX KEYTOOL – Use ctx keytool to enable and disable the IMA encryption function and generate, load, update, permit, disable, or back up farm key files.

Question fifty one. How To Upgrade/migrate Your Xenapp?

Answer :

We can't upgrade to xenapp 6.5 due to architure defrence so, if we want to transport to top version there is a option of migration.

Steps:1. Create a brand new farm with the xenapp 6.5 and use the migration device and specify the source farm to new farm and then migration software will take a look at for the compatibility of apps with new farm and after that it's going to migrate the old farm to new farm.

Question 52. What Is Workspace Control?

Answer :

Use workspace control to permit customers to disconnect fast from all sources (applications, content material, and computer systems), reconnect to disconnected assets, and log off from all sources. This permits customers to transport between devices and benefit get right of entry to to all of their sources (disconnected most effective or disconnected and lively) either after they go browsing or manually at any time. For example, clinicians in hospitals might also want to move among workstations and get right of entry to the equal set of sources each time they go online.
