Exam Name: Citrix XenApp 6.5 Administration

Exam A

QUESTION 1Scenario: A XenApp administrator must recommend a database option for the new XenApp 6.5 data store. Thenew farm will have more than 100 XenApp servers and 500 published resources, support more than 5,000concurrent users and have two zones separated by a WAN connection.

Which two database options should be administrator recommend? (Choose two.)

A. IBM DB2 9.7B. Oracle Enterprise 1.1C. Microsoft SQL Server 2008D. Microsoft SQL Server Express 2008

Correct Answer: BCSection: (none)Explanation

Explanation/Reference:http://support.citrix.com/proddocs/topic/xenapp65-planning/ps-planning-datastore-intro-v2.html

Microsoft SQL Server and Oracle are suitable for any size environment and are recommended for all large andenterprise environments. When deploying large farms across a WAN, you can obtain a performance advantageby replicating the data store and distributing the load over multiple database servers. SQL Server and Oracleare suitable for large farms and support replication.

SQL Server Express is suitable for all small and many medium environments located in one physical location,which do not have branch offices across a WAN

QUESTION 2Scenario: The administrator of a small XenApp server farm has configured end-to-end encryption between theXenApp servers and user devices by setting up Access Gateway VPX. Session Reliability is enabled in the farmwith default settings.

Over which port will published applications be delivered?

A. 80B. 443C. 1494D. 2598

Correct Answer: BSection: (none)Explanation

Explanation/Reference:Explaination:

End to end encryption between means the communication run over port 443 (SSL CAG)

QUESTION 3Scenario: The administrator of a XenApp Enterprise Edition server farm is configuration Single Sign-on for theusers of the farm. The Citrix license server was installed with the default vendor daemon and console Web portnumbers, but NOT the default license server port number.

Of the port numbers that are in use in the XenApp server farm, which one should the administrator specify forthe license server during Single Sign-on configuration?

A. 443B. 7279C. 8082D. 27009

Correct Answer: DSection: (none)Explanation

Explanation/Reference:Reference: http://xenapps.blogspot.com/2011/02/network-communication-ports-used-by.html (licensingservice)

the license server port is configurable between 27000-27009 so only answer can be 27009

QUESTION 4An administrator needs to install a XenApp 6.5 server to act as an additional dedicated data collector. Afterinstalling XenApp on the new server, the next step is to configure it by enabling the __________.

A. Session-host mode onlyB. Controller and Session-host modesC. data collector and XML Broker host modeD. data collector and XTE Service host mode


Explanation/Reference:Explanation:

All XenApp servers can host sessions. The XenApp server mode specifies whether the server can only hostsessions (session-host only mode, also called session-only) or if it can also perform the controller functions ofbeing elected a data collector and hosting the XML broker (controller and session-host mode, also calledcontroller).

QUESTION 5Scenario: An administrator manages a XenApp farm that uses Citrix Provisioning Services to automate theaddition of XenApp servers to the farm.

QUESTION 13Scenario: An administrator has published Microsoft Excel on two identical servers and has placed those serversin a worker group. There are 150 users in the environment, and each server must be allowed to accept all 150-user sessions for failover purposes. All users start work at 09:00 in the morning. The administrator also wantsto prevent the servers from failing due to excessive connection attempts during this logon time.

What can the administrator do to ensure that the server farm can meet these requirements?

A. Assign the default load evaluator to the worker group.B. Assign the advanced load evaluator to the worker group.C. Create a load balancing policy and assign it to the worker group.D. Create a custom load evaluator and assign it to the worker group.


Explanation/Reference:Reference:

default & advanced load evaluators cannot be changed:

- the default Load evaluator never accepts more than 100 connections (100x100=10.000 = full load) = wrong- the advanced Load evaluator has load throttling on HIGH enabled by default meaning a during logontime afew people can login at once + no connection limit so it should be correct

QUESTION 14Scenario: A server farm consists of dual and single processor servers. The administrator wants to ensure thatthe dual-processor servers receive more sessions than the single-processor servers. In addition theadministrator wants to ensure that no server receives more than 100 user sessions.

In order to meet these requirements, the administrator must assign the__________. (Choose the correct optionto complete the sentence.)

A. custom load evaluator rule to all servers.B. advanced load evaluator rule to an serversC. custom load evaluator role to all dual processor serversD. advanced load evaluator rule to an dual-processor servers


Explanation/Reference:Reference

advanced to dual cpu servers doesn't stop wih 100 users = wrongadvanced to all servers doesn't stop wih 100 users = wrongso must be answer A or C,

make a custom load evaluator with cpu % and user load = max 100 to all servers so that:

- when a single cpu server ( with <100 users) reaches its max cpu percentage it will report full load and doesn'taccept more users so therefore multicpu can host more sessions when the cpu isn't at its max- when a multi cpu server reache max users (100) or max cpu% it won't accept anymore users either

Exam C

QUESTION 1Scenario: An administrator has a server farm with five servers. The administrator wants to limit the number ofMicrosoft Excel published application sessions that can be run in the server farm.

Which two steps could the administrator take to meet this requirement? (Choose two.)

A. Configure the Load Throttling rule.B. Configure the Server User Load ruleC. Configure the Application User Load ruleD. Assign a load evaluator to the five servers.E. Assign a load evaluator to the published application

Correct Answer: CESection: (none)Explanation

Explanation/Reference:Reference: - make a custom load evaluator rule, set the application user load rule to report full load at 5, select excel asapp

QUESTION 2Scenario: A server farm has five servers which are members of the FARM worker group. Multiple applicationsare published on the servers for use by over 100 employees. One of the applicationshas only 10 licenses.

What could the administrator do to allow only 10 employees to use that specific application at any given time?

A. Set the concurrent logon limit to 10.B. Apply the limit user sessions policy using a filter.C. Assign a load evaluator to the published application.D. Apply the connection access control policy using a filter.


Explanation/Reference:Reference:- concurrent logon limit is max connection per user = wrong- limit user sessions policy = The maximum number of concurrent connections a user can establish = wrong- access control filter = filter on connection (ag) = wrong

QUESTION 3Scenario: A server farm has 12 servers in the FARM worker group with more than 1,000 users and 20published applications. Two of the published applications perform excessive CPU context switches.

What can the administrator do to ensure that the resource-intensive applications will run optimally in the serverfarm?

A. Assign a load evaluator to the FARM worker group.B. Assign a load evaluator to both resource-intensive applications.

C. Apply the multi-Stream policy to both resource-intensive applications.D. Apply the session importance policy to both resource-intensive applications



- multi stream policy has nothing todo with this = wrong- session importance policy only is not enough to give an app more cpu cycles, you also need to enable thepreferential load balancing and change the app's priority to high = 3 steps = wrong

assign a (custom) load evaluator to the apps with CPU % enabled assures the app won't start another time onthat server -> B

QUESTION 4Scenario: An administrator plans to add printer drivers to the auto-replication list in a XenApp 6.5 environment.The administrator needs to ensure that a specific vendor printer driver is available on all servers in the farmincluding any new servers that are added at a later date.

(Choose two.)

A. Disable the client printer redirection policy.B. Enable the policy for the generic universal printer.C. Enable the policy for the printing preview preference.D. Configure the auto-create client printers policy so that client printers are NOT auto-created.E. Configure the printer driver mapping and compatibility policy to map all drivers to the Citrix Universal Printer

Driver.

Correct Answer: BESection: (none)Explanation


a won't give a client printer at allc printing preview won't give you a printerd not created = no client printer

so B,E

QUESTION 6An administrator performs an installation of XenApp without changing any of the default settings. When a userconnects with a client printer that does NOT have a suitable driver installed, but does have a suitable driveravailable in the driver store, which action will happen?

A. Confirm the resultant set of Citrix policies.B. Check the event logs on the XenApp servers.C. Check the event logs on the client workstations.D. Restart the Print Spooler on the XenApp servers.E. Verify that the Citrix Print Manager Server is running.

Correct Answer: BDESection: (none)Explanation

Explanation/Reference:Explanation: IMO not enough info in question.. facts:

- 1 server farm -> a stopped service could be the problem affecting all users- some auto created printers are present -> some...not all??- user are unable to see their printers -> all users? some users? newly logged in users?

- confirm the resultant set of citrix policies: yeah maybe some other admin changed user group memberships,changed the policy filter...? so yes A = correct

- Check the event logs on the xenapp server Yes well since its just 1 server i would check them for sure! B=Correct

- Restart the printerspooler on the xenapp server? the question speaks about ' their printers' is that networkpinters too? if yes then i would restart the printspooler = Correct

- if the citrix print manager service has stopped printers arent autocreated anymore , the admin logs in andsees some auto-created printers (maybe from other users?) , some indicates not all?? if the citrix print managerservice had stopped in the middle of the day some users have their autocreated printers and some not... iwould verify if the service was started E = correct

- check event logs on client workstations? that would be the last step in troubleshooting if all the other optionsdidn't work = wrong

so in my opinion more than 3 answers are possible, i choose the ones i think are the best answers..

QUESTION 14Scenario: An entire Shift of workers arrives at the office at 09:00 AM two thousand users turn on their thin clientterminals and launch the line of business application within a ten-minute timeframe. The resultant traffic is sointense that it takes 15-20 minutes until everybody is able to start working.

How can the administrator prevent this issue from affecting the user experience?

A. Implement a NetScaler load balancer to distribute the XML trafficB. Configure a Pre-lunch application to be started for users before they arrive.C. Upgrade the XenApp farm database server to a cluster with real time replication.D. Configure additional zone data collectors to manage the numerous concurrent logins.



netscaler load balances the connections of webinterfaceservers and xml servers, but that doesn't help with thelaunch time if everyone connects at the same time, probably the profile loading will cause this, with pre launchthe sessions can be started before the user connects and therefore they won't have to wait that long

Exam D

QUESTION 1Scenario: Users complain that first thing in the morning they receive errors when trying to launch theirapplication and have to re-try many times. At other times of the day, there are NO issues? What could becausing the morning issue?

A. A load throttling load evaluator is limiting the number of concurrent logons.B. A scheduling to load evaluator is restricting the maximum server load at this time.C. A server load evaluator is limiting the number of concurrent users in the farm.D. An application user load evaluator is limiting the maximum number of users allowed to run the application.


Explanation/Reference:Explanation:if the impact on load throttling is set too high the server reports full load when too many users connect at thesame time. With too less servers they all can be fully loaded at prime time in the morning
