and Load Balancing
1 . You are configuring your XenApp farm with a policy for Session Importance.
You have configured the policy with the proper settings for Session
Importance. You have configured the policy to filter based on Access Control.
This is also configured correctly. When users log in via Access Gateway, the policy is not being applied to them. Which of the following is most likely the cause of the problem?
A . In order for Session Importance to work properly, a policy for Zone preference and failover must also be configured.
B . The option Trust requests sent to the XML Service is not enabled.
C . The user is logging in via Access Gateway Advanced Edition and not Access Gateway Enterprise Edition .
D . The user is using a MAC client, which does not support Session Importance .
Correct Answer & Explanation: B . In order to use policy filters based on Access Control, the option for Trust requests sent to the XML Service must be enabled.
Incorrect Answers & Explanations: A , C , D . Answer A is incorrect because the Session Importance policy does not require any other policies to be set.
Answer C is incorrect because Access Gateway Advanced Edition supports the Access Control filter. Answer D is incorrect because Session Importance is a server-side policy; therefore the client does not matter.
2 . You are configuring your XenApp farm to allow PDA synchronization via USB. You have enabled the policy for Turn on automatic virtual COM port mapping . You have installed the appropriate synchronization software.
When users log in with a USB PDA, they are still unable to synchronize.
What is most likely the cause of the problem?
A . COM port mapping is disabled. COM port mapping needs to be enabled along with virtual COM port mapping.
B . COM port mapping is enabled. This interferes with virtual COM port mapping.
C . TWAIN redirection is disabled. TWAIN redirection needs to be enabled along with virtual COM port mapping.
D . There is not enough bandwidth available for PDA synchronization to occur properly.
Correct Answer & Explanation: A . In order for USB PDA synchronization to work properly in a XenApp session, COM port mapping and virtual COM port mapping both have to be enabled.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because COM port mapping must be enabled along with virtual COM port mapping , in order for USP PDA synchronization to function properly.
Answer C is incorrect because TWAIN redirection will not affect PDA synchronization. Answer D is incorrect because session bandwidth will not prevent USB PDA synchronization. Lack of bandwidth can cause the synchro-nization to take a long time, however.
3 . You have configured a XenApp policy to disable client drive mapping. You only want this policy to be applied to specific clients. You configured the policy with a filter for client name. You configured the filter with the names of the clients that should have their client drives disabled. When users log in from these clients, the policy is not being applied. What is most likely the cause of the problem?
A . There is a lower priority policy overriding the policy that disables the drive mappings.
B . Users are connecting to a XenApp Advanced Edition server, and not a XenApp Platinum Edition server.
C . The user is logging in as an administrator, and therefore his or her client drive mappings cannot be disabled.
D . Users are logging in through Web Interface, which is using randomly generated client names.
Correct Answer & Explanation: D . When users log in via Web Interface, Web Interface can generate a random client name. If this is the case, then the client names given in the filter will not match the randomly generated name.
Incorrect Answers & Explanations: A , B , C . Answer A is incorrect because a lower priority policy will not override a higher priority policy. Answer B is incorrect because XenApp Advanced Edition supports XenApp policies. Answer C is incorrect because even administrators can have their client drives disabled.
4 . You have configured several policies in your XenApp farm. All of your policies are applied to user groups. A user is reporting that his client drive mappings have been disabled. Drive mappings should not be disabled for this user.
You have lost track of all the policies that apply to the user. Therefore, you are unsure which policy may be disabling the client drives. How can you best determine which policies apply to the user?
A . Use the Policy Search Engine.
B . View the properties for the user in the Citrix XenApp Advanced Configuration tool.
C . View the properties for all the policies you have configured.
D . Remove all the filters you have configured and reconfigure them.
Correct Answer & Explanation: A . The Policy Search Engine can be used to find policies that match given filter criteria.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because you cannot view user properties in the Citrix XenApp Advanced Configuration tool. Answer C is incorrect because checking the properties for a policy will show you the rules you have configured, not the filters. Answer D is incorrect because, although you could remove all and reconfigure the filters, this would not provide you with information regarding all the currently configured policies.
5 . You have just configured several new policies. You would like to determine how these new policies will affect a certain user account. How can you determine how the new policies will affect the user before the user logs into the farm?
A . There is no way to determine how the user will be affected without having the user log in.
B . Use the Resultant Set of Policies (RSOP) tool.
C . Enable Policy Logging.
D . Enable Configuration Logging.
Correct Answer & Explanation: B . The RSOP allows you to view what policy settings will be applied to a session before the session is established.
Incorrect Answers & Explanations: A , C , D . Answer A is incorrect because there is a way to determine this information without the user having to log in.
Answer C is incorrect because there is no separate policy logging feature.
Answer D is incorrect because the Configuration Logging feature does not supply you with this type of information.
6 . Your organization consists of a main office and a field office. Users commonly move between the offices. The two sites are on separate networks but are connected via a WAN. You want client drive mappings disabled for clients in the field office, but not the home office. How can this be accomplished?
A . Create a policy disabling client drive mappings. Apply a Client IP Address filter to the policy.
B . Create a policy disabling client drive mappings. Apply a Client Name filter to the policy.
C . Create a policy disabling client drive mappings. Apply a User filter to the policy.
D . Create a policy disabling client drive mappings. Apply a Location filter to the policy.
Correct Answer & Explanation: A . Since the two sites are on separate networks, they should have different IP address ranges. Therefore, you can apply the policy only to the field office IP range.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because clients move between different sites. Therefore, a given client can be at either site on any given day. Answer C is incorrect because clients move between different sites. Therefore, a given user can be at either site on any given day.
Answer D is incorrect because there is no specific Location filter. Locations are generally differentiated using IP address ranges.
7 . You are using Password Manager in your XenApp environment. You need a way to configure the Password Manager Credential Store. The credential store is on a Windows file server. What is the best way to accomplish this?
A . Use the default file share credential store.
B . Create a registry entry on all of your XenApp servers with the location of the credential store.
C . Create a XenApp policy using the Password Manager Credential Store policy rule.
D . Use Installation Manager to push the Password Manager plug-in to all your XenApp servers.
Correct Answer & Explanation: C . The Password Manager Credential Store policy rule allows you to specify a UNC share for your Password Manager Credential Store.
Incorrect Answers & Explanations: A , B , D . Answer A is incorrect because there is no default file share credential store in Password Manager. Answer B is incorrect because setting registry entries may work, but it’s not the best method. Answer C is incorrect because simply pushing out the plug-in via Installation Manager will not configure the plug-in with a credential store.
8 . Which load rules are included in the Default Load Evaluator?
A . Load Throttling and Server Load B . Load Throttling and CPU Usage C . CPU Usage and Server Load D . CPU Usage and Memory Usage
Correct Answer & Explanation: A . The Default Load Evaluator includes the Load Throttling and Server Load rules.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because the CPU Usage load rule is not included. Answer C is incorrect because the CPU Usage load rule is not included. Answer D is incorrect because neither the CPU Usage nor the Memory Usage rule is included.
9 . You have configured multiple XenApp policies. You want to configure a Zone preference and failover (ZPF) policy to set the preferred zone for a group of users to Group 1. You want to configure a second ZPF policy to set the preferred zone for everyone else to Group 2. You configured both policies, but all users are being directed to Group 2 as their preferred zone. What can be done to fix this and still achieve the desired result?
A . Remove the policy specifying Group 2 as the preferred zone.
B . In addition to the ZPF rule, you should also add a Session Importance rule.
C . Disable session sharing.
D . Ensure that the policy setting the Group 1 preferred zone is a higher priority than the policy setting Group 2 as the preferred zone.
Correct Answer & Explanation: D . The policy specifying a specific user group should have a higher priority. Then users who don’t fall into that group will have the other policy applied.
Incorrect Answers & Explanations: A, B, C . Answer A is incorrect because if the policy is removed, then no one will have Group 2 set as their preferred zone. Answer B is incorrect because Session Importance alone will not affect ZPF. Answer D is incorrect because although session sharing may affect ZPF, that is not the problem in this case.
10 . Frequently, when users are reading documents with a document reader published on your XenApp servers, they encounter links to web sites and media files. These web sites and media files are opened using a browser also published on your XenApp servers. The high number of browser sessions and media sessions being opened is causing high resource utilization on your servers. In order to reduce the utilization on your servers, you want these links to be opened using the local client browser. Which policy setting should you enable to accomplish this?
A . Server to client content redirection B . Zone preference and failover C . Session Importance
D . Client to server content redirection
Correct Answer & Explanation: A . Server to client content redirection will allow URL accessed on the server to be opened using a client browser.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect,because Zone preference and failover controls sessions, not links within a session.
Answer C is incorrect because Session Importance controls the resources provided to a session, not where links are processed. Answer D is incorrect because Client to server content redirection allows local documents to be opened using server applications.
11 . Which of the following load rules are included in the Advanced Load Evaluator?
A . Server Load and Load Throttling
B . CPU Utilization, Load Throttling, Memory Usage, and Page Swaps C . CPU Utilization, Memory Usage, Disk Data I/O, and Page Swaps D . Memory Usage, Page Swaps, Page Faults, and Load Throttling
Correct Answer & Explanation: B . CPU Utilization, Load Throttling, Memory Usage, and Page Swaps are included in the Advanced Load Evaluator.
Incorrect Answers & Explanations: A , C , D . Answer A is incorrect because Server Load and Load Throttling are included in the Default Load Evaluator, not the Advanced Load Evaluator. Answer C is incorrect because Disk Data I/O is not included in the Advanced Load Evaluator. Answer D is incorrect because Page Faults is not included in the Advanced Load Evaluator.
12 . Users in the Finance Department use financial applications published on your XenApp servers. The XenApp servers themselves are secure, as are the applications. You are worried that sensitive data being transmitted over the network could be intercepted. Which policy rule should you enable to secure data communication?
A . SecureICA B . SSL Relay
C . Session Importance
D . Zone preference and failover
Correct Answer & Explanation: A . SecureICA secures communication between the client and the server. SecureICA allows you to set a level of encryption that is to be used throughout the session.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because although SSL Relay will secure communications, it is not available via policies. Answer C is incorrect because Session Importance will not secure communications. Answer D is incorrect because Zone preference and failover will not secure communications.
13 . Your company has offices in New York, Los Angeles, London, Brisbane, and Tokyo. You have XenApp architecture that consists of one farm. But you have XenApp servers in New York, London, and Tokyo. You want users to use the XenApp server that is closest to their physical location. Which policy rule should you enable to accomplish this?
A . Server to client content redirection B . Session Importance
C . Zone preference and failover D . Configure delivery protocol
Correct Answer & Explanation: C . Zone preference and failover can direct user sessions to a specific group of servers. This group of servers is known as a primary zone.
Incorrect Answers & Explanations: A , B , D . Answer A is incorrect because Server to client content redirection does not designate a group of servers as the primary resource for user sessions. Answer B is incorrect because Session Importance does not designate a group of servers as the primary resource for user sessions. Session Importance will just direct a session to the least busy server. Answer D is incorrect because it is used to define a delivery mechanism for Application Streaming.
14 . When Preferential Load Balancing is enabled, which of the following is used to calculate Resource Allocation?
A . Session Importance and Max Application Importance B . CPU Utilization and Memory Usage
C . User Importance and Session Importance D . Server Load and Application Importance
Correct Answer & Explanation: A . Resource Allocation = Session Importance × Max Application Importance.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because neither CPU Utilization nor Memory Usage is used in the calculation.
Answer C is incorrect because User Importance is not used in the calculation.
Answer D is incorrect because Server Load is not used in the calculation.
15 . When using Preferential Load Balancing, which of the following formulas is used for determining CPU utilization distribution?
A . CPU Distribution = (Application Importance) / (Session Importance) B . CPU Distribution = (Session Importance) ∗ (Application Importance) C . CPU Distribution = (Session Allocation) ∗ (Total Server Session
Allocations)
D . CPU Distribution = (Session Allocation) / (Total Server Session Allocations)
Correct Answer & Explanation: D . CPU distribution = (Session Allocation) / (Total Server Session Allocations)
Incorrect Answers & Explanations: A, B, C . Answer A is incorrect because Session Importance and Application Importance are not used in the calculation.
Answer B is incorrect because Session Importance and Application Importance are not used in the calculation. This is actually the formula for Resource
Allocation. Answer C is incorrect because the formula is a quotient, not a product of Session Allocation and Total Server Session Allocations.
16 . You have configured multiple XenApp shadowing policies. You want settings in these policies to be merged together. But you realize only the highest priority policy is being applied. What is most likely the problem?
A . Policies are always applied in order of priority.
B . Shadowing was disabled at server install.
C . You have not enabled Merging Shadow policies.
D . You are using XenApp Enterprise Edition and not XenApp Platinum Edition .
Correct Answer & Explanation: C . You must explicitly enable the merging of shadow policies in order for this to occur. This setting is enabled under farm properties in the Citrix Access Management Console.
Incorrect Answers & Explanations: A, B, D . Answer A is incorrect because although most policies are processed in order of priority, shadowing policies can be merged together if configured to do so. Answer B is incorrect because if shadowing had been disabled at server install, no one would be able to shadow. Answer D is incorrect because Merging Shadow policies can be enabled in XenApp Enterprise Edition .
17 . You are having a problem with load balancing in your XenApp farm. Users are not being directed to one of your servers. You want to check current load activity on this server. What is the best way to do this?
A . Use Load Manager Monitor.
B . Use Load Manager Logging.
C . View Load Evaluator Usage reports.
D . Use Performance Monitor.
Correct Answer & Explanation: A . Load Manager Monitor will show you real-time load data for your server.
Incorrect Answers & Explanations: B , C , D . Answer B is incorrect because Load Manager Logging will not show you current load usage data. It will, however, show you connection data. Answer C is incorrect because Load Evaluator Usage Reports will only show you what Load Evaluators are being used by which servers and applications. They will not show you actual load data.
Answer D is incorrect because Performance Monitor will show you server uti-lization but not load XenApp load data.
18 . Which of the following commands can be used to view application load in your XenApp farm?
A . query session B . qfarm/app C . qfarm/load D . query load
Correct Answer & Explanation: B . Typing the qfarm/app command at a command prompt will allow you to see application load data for your XenApp farm.
Incorrect Answers & Explanations: A , C , D . Answer B is incorrect because query session will only return a list of current sessions. It does not return load information. Answer C is incorrect because it will return server load data, not application load data. Answer D is incorrect because it is an invalid command. There is no load option available with the query command.
19 . Users in your organization are complaining that sound is not working in their XenApp sessions. After some investigation, you realize that there is a policy disabling client audio mapping. You disable this policy, but users still cannot play audio within their sessions. What is most likely the issue?
A . There is another policy disabling the sound.
B . You did not have the proper permissions to change the policy.
C . The server is low on resources, and sound has been automatically disabled.
D . Users need to log out and log back in for the policy change to take effect.
Correct Answer & Explanation: D . XenApp policies last for the length of a session. In order for users to receive new settings, they have to establish a new session.
Incorrect Answers & Explanations: A, B , C . Answer A is incorrect because although it’s a possibility, it is not the mostly like cause. Answer B is incorrect because you would have not been allowed to make the policy change if you didn’t have the appropriate permissions. Answer C is incorrect because the server will not automatically disable sound.
