Which of the following is an advantage of creating an alternate profile?

  • A. The profile may be created to make it more accessible to a user device
  • B. The profile may act as a backup when the primary profile fails
  • C. The profile is accessed when the load on the file server with the primary profile is too high
  • D. The profile provides an alternate pathway to the same package


Answer : A

Explanation:
For streamed applications only, use this feature to add an alternate profile for connections that come from specific IP addresses. For example, use an alternate profile to allow one published application for users on either side of a WAN with file servers on their side. When you create an alternate profile, you create a duplicate of the primary profile that is located on a different file share, which is more accessible to the user device. Source: Citrix Product

You reduced the user privileges to Run application as a least privileged account for an application that is streamed to the client in order to mitigate security risks. Some administrators have complained that the application fails to operate currently. Which of the following may be a cause for this?

  • A. The application may require that users have elevated privileges; the setting configures all users, even administrators to run the application with normal user privileges
  • B. The application may not run when administrators privileges are modified
  • C. The application may not run for administrator accounts
  • D. The application has been corrupted


Answer : A

Explanation:
Before you select Run application as a least-privileged user account, test the application with a limited access configuration. Some applications expect users to have elevated privileges and might fail to operate correctly when launched by users with a leastprivileged user account.

Which of the following helps reduce power consumption and manage capacity of the
XenApp servers?

  • A. Having a larger capacity of XenApp servers than the number utilized during peak loads.
  • B. Fool-proof Redundancy and failover policies for XenApp servers.
  • C. Dynamically scaling up and down the number of online XenApp servers.
  • D. Remote management of servers 24X7.


Answer : C

Explanation:
Power and Capacity Management helps reduce power consumption as well as improve management of XenApp server capacity by dynamically scaling up or scaling down the number of online XenApp servers. Consolidating sessions onto fewer online servers improves server utilization, while providing sufficient capacity to handle load and minimizing unnecessary power consumption.

Who/what is a load evaluator?

  • A. A role assigned to an administrator. Load evaluators work with super administrators to set the rules in the Load Manager.
  • B. Another name for the Load Manager.
  • C. A plug-in that exists on each server that has been provisioned in the farm. It works with the Load Manager and the Infrastructure Servers to determine load on each server.
  • D. A component of the Load Manager module that may be attached to the server or to each application. It uses rules to determine the load on the server.


Answer : D

Explanation:
Load Manager calculates the load on a server using load evaluators and rules. Each load evaluator contains one or more rules. Each rule defines an operational range for the server or published application to which its evaluator is assigned. Source: Citrix Product

Server utilization can be improved by:

  • A. Consolidating sessions onto fewer online servers
  • B. Putting a cap on the number of active sessions at any given time
  • C. Dynamically reallocating sessions to available servers Keeping the failover servers in standby mode and powering them up only when necessary.


Answer : A

Explanation:
Citrix XenApp Power and Capacity Management can help reduce power consumption and manage XenApp server capacity by dynamically scaling up or scaling down the number of online XenApp servers. Consolidating sessions onto fewer online servers improves server utilization, while providing sufficient capacity to handle load while minimizing unnecessary power consumption. As users log on to the system and reduce the idle capacity (how much capacity is available for additional sessions), other servers in the workload are powered up.
As users log off and idle capacity increases, idle servers are shut down. This helps optimize capacity for XenApp workloads. Source: Citrix Product Documentation

Your users are complaining of slow performance of a particular application published in your farm. You want to set a limit on the number of users allowed to connect to this application. Which of the following rules would you use?

  • A. Server User Load
  • B. Load Throttling
  • C. CPU Utilization
  • D. Application User Load


Answer : D

Explanation:
Application User Load limits the number of users allowed to connect to a selected published application. This rule monitors the number of active ICA sessions using the published application. The default value to report full load is 100. Source: Citrix Product

One of the servers in your farm is failing when many users try to connect to it concurrently.
Which Load Manager rule would help you mitigate this issue?

  • A. Load Throttling
  • B. Scheduling
  • C. Server User Load
  • D. Context Switches


Answer : A

Explanation:
Load Throttling limits the number of concurrent connection attempts that a server handles.
This prevents the server from failing when many users try to connect to it simultaneously.
The default setting (High impact) assumes that logons affect server load significantly. This rule affects only the initial logon period, not the main part of a session. The Load Throttling rule can be applied only to a server, not to an individual application. Source: Citrix Product

Scenario: After diligently monitoring the server farm, an administrator decides that she needs a load management strategy that will include defining ranges for the processor, memory, number of concurrent connection attempts and number of transfers of data between physical memory and the page file for every server in the farm. Which of the following strategies should the administrator implement?

  • A. Create a custom load evaluator; add the CPU Utilization, Memory Usage, Load Throttling and Page Swap rules. Apply the load evaluator to all servers in the farm
  • B. Apply the Default load evaluator to all servers in the farm
  • C. Apply the Advanced load evaluator to all servers in the farm
  • D. Duplicate the Default load evaluator, add the missing rules to the new load evaluator and apply it to all servers in the farm


Answer : C

Explanation:
The Advanced load evaluator has all of the rules that the administrator is looking for: CPU
Utilization, to define the range of processor utilization; Memory Usage, to define the range of memory usage; Load Throttling, to limit the number of concurrent connection attempts; and Page Swap, to define the range of page swaps (transfers of data between physical memory and the page file) per second.

Scenario: An administrator is asked to deploy a new resource-intensive multimedia application to the design department. While testing the application, the administrator decides that it will need to be published on its own group of Presentation Servers and that the most important resources to keep in check on the group of servers are the processor and RAM, and nothing else. How should the administrator proceed with load management?

  • A. Create a custom load evaluator with the CPU Utilization and Memory Usage rules and apply it to the desired servers
  • B. Create a custom load evaluator with the Server Usage Load and CPU Utilization rules and apply it to the desired servers
  • C. Apply the Advanced load evaluator to the desired servers
  • D. Do nothing and allow the Default load evaluator to continue managing the load


Answer : A

Explanation:
The administrator should create a custom load evaluator with the CPU Utilization and
Memory Usage rules and apply it to the desired servers. The CPU Utilization rule defines the range of processor utilization for a selected server. The Memory Usage rule defines the range of memory (RAM) usage for a server. The Advanced load evaluator includes CPU
Utilization, Load Throttling, Memory Usage and Page Swap rules, but the administrator didnt want the two extra rules for these servers. The Default load evaluator includes the
Load Throttling and Server User Load rules. Source: Citrix Product Documentation

Which of the following load evaluator rules are calculated on conditions being either true or false? (Choose 2)

  • A. Application Server Load
  • B. Server User Load
  • C. IP Range
  • D. Scheduling


Answer : C,D

Explanation:
IP Range and Scheduling are both Boolean rules, based on conditions being true or false.
IP Range defines the range of allowed or denied client IP addresses for a published application. Scheduling schedules the availability of selected published applications.
Boolean rules must be used in conjunction with at least one other rule because they do not return actual load values for a server. Source: Citrix Product Documentation

Scenario: After doing some diligent testing of a new application that is going to be published on a group of servers in the farm, the administrator concludes that the best strategy for load management will be by: 1. Defining the number of times the operating system is allowed to switch from one process to another; 2. Limiting the number of concurrent connection attempts the servers are expected to handle; and 3. Limiting the number of sessions allowed to connect to each server. How should the administrator configure load management?

  • A. Apply the Advanced load evaluator to the published application
  • B. Apply the Advanced load evaluator to the desired servers
  • C. Apply a custom load evaluator to the published application
  • D. Apply a custom load evaluator to the desired servers


Answer : D

Explanation:
The administrator in this scenario should create a custom load evaluator with the Context
Switches, Load Throttling and Server User Load rules. Then he should apply the custom load evaluator to the servers that are running the published application that he is concerned about. The Context Switches rule defines the number of times the operating system switches from one process to another. The Load Throttling rule limits the number of concurrent connection attempts a server is expected to handle and cannot be applied to an individual application. The Server User Load rule limits the number of sessions allowed to connect to a selected server. Source: Citrix Product Documentation
