Exam Prep Questions
1.

If you decide to use the default load evaluator to spread user load among servers, when will the evaluator report a full load and start refusing incoming user sessions?

  1. When the user load reaches 100 users

  1. When the user load reaches 1,000

  1. When the user load reaches 1,500

  1. When the user load reaches 2,000

A1:

Answer A is correct. The default load evaluator is preconfigured to report a full load when the server reaches 100 users. Choices B, C, and D are incorrect because the configured values do not reflect the number that is preconfigured by default.

2.

Your Citrix server farm consists of 10 load-balanced servers that were all purchased at the same time, and they all have identical hardware. The servers load balance your CRM application, which is very CPU intensive . Your organization has just acquired another company, and this acquisition now requires the expansion of your server farm. You order 5 new servers with faster CPUs. What should you do to make sure the load is properly spread?

  1. Create or modify your load evaluator to include the CPU Utilization rule.

  1. Create or modify your load evaluator to include the Page Swaps rule.

  1. Create or modify your load evaluator to spread load based on the Server User Load rule.

  1. Create or modify your load evaluator to spread load based on the Memory Usage rule.

A2:

Answer A is correct. Because your new hardware has faster CPUs, the ideal load evaluator would be to load manage servers based on CPU Utilization. This way, you ensure that all servers can handle the proper number of users. Obviously, the more advanced servers will handle more sessions than the ones with older hardware. Choice B is incorrect because this configuration does not take advantage of the new CPUs installed with the new hardware, and because the application is CPU intensive. Choice C is incorrect because Server User Load is not the correct configuration when you are dealing with server hardware that is not identical. Choice D is incorrect because there is no mention of the new servers having more memory than the older ones. In addition, the CRM application is CPU intensive.

3.

Which of the following can be classified in the Boolean type or category? (Choose all that apply.)

  1. Memory Usage

  1. Context Switches

  1. Disk Operations

  1. IP Range

A3:

Answer D is correct. The Boolean type or category consists of a permit or deny rule. Members of this category include IP Range and Scheduling. Choice A is incorrect because Memory Usage belongs to the Moving Average category. Choice B is incorrect because Context Switches belongs to the Moving Average Compared to High Value category. Choice C is incorrect because Disk Operations also belongs to the Moving Average Compared to High Value category.

4.

When you activate an MPS 3.0 Advanced or Enterprise Edition license, which load evaluators come preconfigured? (Choose all that apply.)

  1. Static

  1. Standard

  1. Advanced

  1. Default

A4:

Answers C and D are correct. The two preconfigured load evaluators that come with MPS 3.0 Advanced and Enterprise Editions are advanced and default. Choices A and B are wrong because no such load evaluators exist.

5.

Your environment consists of five load-balanced MPS 3.0 Advanced Edition servers. You have published the Microsoft Office suite on all five servers named Servers 1 through 5. Server 1 has gone down due to hardware issues. What happens to the users who are connected to this server?

  1. The sessions are lost, but when users reconnect , their session will be in the state where they left it before the server went down. No data is lost.

  1. Because the servers are running MPS 3.0 Advanced Edition, which supports load balancing, all the sessions are automatically spread over the remaining servers.

  1. The sessions are lost. The users will have to reconnect to the published application. Any unsaved data is lost, and a new session is started.

  1. Because MPS 3.0 Advanced Edition is being used, built-in code will notice the server is experiencing hardware issues and will save users' work automatically and log them off gracefully, thus not causing any loss of work in progress.

A5:

Answer C is correct. As mentioned earlier, load balancing is not fault tolerance; therefore, in the event that a server goes down for any reason, all sessions on that server are lost and cannot be recovered; plus, any unsaved work is lost. Choices A, B, and D are incorrect because they do not describe the true functionality of load balancing.

6.

When you create a load evaluator with multiple rules in it, how do these rules interact together to determine the load on the server? Which of the following statements is true?

  1. When any of the rules reach the defined threshold, the server reports a full load.

  1. The rules conflict, but you can set values to determine which rule takes precedence.

  1. Multiple rules cannot be assigned to the same load evaluator.

  1. Multiple rules automatically interact together to determine the server or published application load.

A6:

Answer D is correct. When multiple rules are assigned to the same load evaluator, the rules automatically work together to determine the overall server or published application load. Choices A, B, and C are incorrect because they are false statements that do not reflect the method by which Load Manager handles multiple rules in load evaluators.

7.

You have just been hired to tweak the Citrix server farm for company ABC. When you launch the Management Console and look at the default load evaluator, you notice its value is set to 100. You want to lower this parameter but notice that all the fields are grayed out. Why?

  1. The default load evaluator is loaded as part of the Advanced and Enterprise Editions and cannot be edited or modified.

  1. You are logged in to the Management Console with a user account that does not have enough privileges to make changes.

  1. The server that holds the load evaluators is down; therefore, you can only view but not modify the values.

  1. Another Citrix administrator has the load evaluator open ; therefore, you are prevented from making changes.

A7:

Answer A is correct. The default load evaluator cannot be modified or edited. This is by design. To get around this limitation, you can create a new load evaluator, give it the same rule as the default one, and modify the value to your liking. Choices B, C, and D are incorrect because they are all false statements.

8.

To maximize your users' ICA session experience, you have created a load evaluator that load balances your users across your 10 servers. The load evaluator allows only 30 users per box. This number ensures a smooth session. Your servers are currently all reporting 30 users. What happens to a new user who tries to connect?

  1. The load evaluator ignores the rule and continues to spread load evenly among all the servers.

  1. The connection is refused .

  1. The load evaluator automatically increases the values of the load evaluator in increments of 10.

  1. The load evaluator automatically increases the values of the load evaluator in increments of 5.

A8:

Answer B is correct. When the servers report a full load, new connections are refused. This is the purpose of setting a value for full load. Setting the value ensures the existing users continue to have a smooth session and the servers are not overloaded to the point where no one can work. Choices A, C, and D are incorrect because they don't reflect the true behavior of the Citrix load-balancing module.

9.

Which application or utility would you use to monitor application load within your Citrix server farm?

  1. The Management Console

  1. Citrix Server Administration

  1. Citrix Load Manager Monitor

  1. Citrix Load Balancing Monitor

A9:

Answer A is correct. The Management Console is the program that you would run to monitor all types of loads on your servers and on your published applications. Choice B is incorrect because Citrix Server Administration is a legacy application that was available with MF 1.8 and has long been replaced and incorporated into the Management Console. Choice C is incorrect because the Load Manager Monitor is part of the Management Console and cannot run independently of it. Choice D is incorrect because no such application exists.

10.

Which flavor of MetaFrame Presentation Server is needed to use the features and functionality of load balancing? (Choose all that apply.)

  1. MPS 3.0, Advanced Edition

  1. MPS 3.0, Standard Edition

  1. MPS 3.0, Corporate Edition

  1. MPS 3.0, Enterprise Edition

A10:

Answers A and D are correct. To use load balancing, you need an MPS 3.0 Advanced or Enterprise Edition license. Choice B is incorrect because Citrix does not offer the load-balancing functionality with MPS 3.0 Standard Edition. Choice C is incorrect because there is no Corporate Edition.

11.

You have a server farm consisting of 10 Citrix servers. Five of these servers are running the TCP/IP protocol and are load balanced among each other. The other 5 are running IPX and are load balanced among each other. What must you do to allow load balancing to occur among all 10 Citrix servers?

  1. You can't. An MPS 3.0 server can listen on only one protocol at a time.

  1. Install TCP/IP on the IPX servers.

  1. Install IPX on the TCP/IP servers.

  1. Install IPX on the TCP/IP servers and TCP/IP on the IPX servers.

A11:

Answer D is correct. If you want to load balance MPS servers with different protocols, both protocols should be present on all the servers. Choice A is incorrect because it is a false statement; two protocols can exist on the same server. Choices B and C are incorrect because they address only part of the issue.
