IBM IBM Certifications C2090-623 Questions & Answers

• Question 11:

  An administrator wants to start the LifeCycle Manager service. How can this be done?

  A. Open IBM Cognos Configuration and start the service.

  B. Open Administrative tools, Services, and start the LCM service.

  C. Use the lcm_start.bat command from a command prompt window.

  D. Type the URL in a browser, http://server_name:port_number/lcm_servlet/webcontent/app/main.

  Correct Answer: C

  Before users can start working in Cognos LifeCycle Manager, you must start the Cognos LifeCycle

  Manager web application.

  Procedure

  Start the Cognos LifeCycle Manager server:

  On a Microsoft Windows system, from the Start menu, click LCM Start.

  You can also type the following command in a command prompt window, from the Cognos LifeCycle

  Manager install location. Depending on where Cognos LifeCycle Manager is installed, you might have to

  run the command prompt window as an administrator.

  lcm_start.bat

  On a Linux system, run the server start script

  install_location/lcm_start.sh

  Start the Cognos LifeCycle Manager web application:

  On a Microsoft Windows system, from the Start menu, click LCM URI.

  Type the following URL in your browser:

  http://server_name:port_number/lcm_servlet/app/main

  Incorrect Answers:

  D: The URL that is used to start the Cognos LifeCycle Manager web application in a browser includes a port number. The port number must match the port number that is specified in the install_location\wlp\usr \servers\lcm\server.xml file.

• Question 12:

  An administrator is reviewing the memory allocations listed below in the current environment.

  

  Which action should the administrator take?

  A. No action is needed.

  B. Increase the current heap size by 20%.

  C. Increase the committed heap size by 50%.

  D. Decrease the maximum heap size by 25%.

  Correct Answer: A

  Incorrect Answers:

  B: If current heap size is close to the maximum heap size, you may want to adjust tuning settings.

  Note: Steps to adjust the JVM heap size are as follows:

  9. From the Welcome page, select the Manage tab and click Administration Console.

  10.Click on the System tab and select the arrow to the right of All servers. Hover over the Services option

  and click Query.

  11.Against your running `QueryService', click Set properties.

  12.Under the Settings tab, identify the tuning options and adjust the following values: Under the Settings

  tab, identify the tuning options and adjust the following values:

  Initial JVM heap size for the query service (MB) (Requires QueryService restart): an ideal value to enable

  the initial size is 4 GB.

  JVM heap size limit for the query service (MB) (Requires QueryService restart): an ideal value to enable

  the maximum or size limit is 16 GB.

• Question 13:

  An administrator is performing tasks in the IBM Cognos Administration console. Which task can be performed on the Status > System page?

  A. Enable and disable schedules to control resource utilization in the system.

  B. Monitor upcoming activities, such as reports and jobs, to identify potential impact on system resources.

  C. Stop and start individual services under the control of a dispatcher, such as the BatchReportService service.

  D. Configure datasource connections so that reports can execute, query the datasource, and return a result set.

  Correct Answer: B

  The area: System, dispatcher, server, and service administration: is used to monitor system performance using system metrics and administer servers.

  Administration console.

  Which of the following options can be performed? (Choose two.)

  A. Importing and exporting specific folder content.

  B. Creating or modifying a Datasource Connection.

  C. Adding new groups and folder to the Cognos namespace.

  D. Adding a new contact and distribution list to the Cognos namespace.

  E. Viewing past and upcoming scheduled jobs and reports and what is currently running.

  Correct Answer: AE

• Question 15:

  An environment has two dispatchers with report servers installed on two machines with following configuration:

  Dispatcher 1 on Computer A RAM: 16384 MB CPU: 2 Core 2.0 GHz Storage: 512 GB Dispatcher 2 on Computer B RAM: 32768 MB CPU: 4 Core 3.4 GHz Storage: 1024 GB

  What should the setting of processing capacity for Dispatcher 2 be set to, if the capacity for Dispatcher 1 is set to 1?

  A. 1

  B. 2

  C. 4

  D. 8

  Correct Answer: B

  If your installation includes more than one dispatcher, you can specify the proportion of requests that each dispatcher handles by changing their processing capacity.

  This is commonly referred to as load balancing. You typically set the capacity for a dispatcher based on the CPU speed of the computer where it is installed. For example, a first dispatcher is installed on a 2 GHz computer and a second dispatcher on a 1 GHz computer. You set the processing capacity of the first dispatcher to 2.0 and the second to 1.0. The first dispatcher handles two-thirds of the requests while the second handles one-third of the requests. If you set the capacity of both dispatchers to 1.0, requests are sent to each dispatcher alternately. The default processing capacity for each dispatcher is 1.0.

• Question 16:

  An administrator needs to ensure that users do not have to enter/select Database credentials when

  running reports.

  What must a datasource have in order to accomplish this?

  A. No signon available to the users.

  B. Only one signon available to the users through permissions.

  C. At least one signon available to the users through permissions.

  D. More than one signon available to the users through permissions.

  Correct Answer: C

  You add signons to data source connections so that users do not have to enter database credentials when they run reports.

• Question 17:

  An administrator wants to use one of the sample audit reports to view the percentage of successful and

  failed requests for the current day.

  What must be done before they can successfully run this report?

  A. Set the logging level for the sample report to Minimal.

  B. Create a datasource connection to the logging database.

  C. Modify the report so that it can be displayed correctly in HTML and PDF formats.

  D. Import the Audit.cpf into the Content Store using the IBM Cognos Administration console.

  Correct Answer: B

  Before you can create audit reports or use the sample audit reports that come with IBM Cognos software,

  you must set up audit reporting.

  Direct log messages to a database.

  Set up a logging database and configure log messages to be sent to the database.

  Set the logging level for audit reports.

  For audit reporting, set the logging level to Basic (auditing enabled) or Request. If you set the logging level

  to Minimum, auditing is disabled. Use Full logging and Trace levels only for detailed troubleshooting

  purposes, under the guidance of Customer Support. They may significantly degrade server performance.

  Enable native query logging

  Incorrect Answers:

  A: If you set the logging level to Minimum, auditing is disabled.

  A. a package and/or group or role

  B. a package and/or a server group

  C. a group or role and/or a server group

  D. a package and/or group or role and/or a server group
