IBM IBM Certifications C2090-623 Questions & Answers

• Question 31:

  An administrator wants to implement load balancing without using an external load balancing mechanism. What is one approach that can be used to achieve this?

  A. Set up a standby Content Manager.

  B. Install a gateway on each database server.

  C. Configure dispatchers together with the content stores.

  D. Configure gateways to direct all traffic to a dedicated dispatcher.

  Correct Answer: C

  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.

• Question 32:

  An administrator has set up audit logging but needs to diagnose, trace, and filter for a specific user during

  peak period of system usage.

  How can this be done?

  A. Delete the appended ipfclientconfig.xml in the install_location\configuration directory.

  B. Increase the logging level to search for the user's first/last name in the audit logging tables.

  C. Set up the Audit Reports package and open the "Users and Reports report", and filter on the user id.

  D. Connect to the JMX Remote Process service by launching jconsole executable and using the CAMID and enable Dye Trace.

  Correct Answer: B

  Use audit logs to view information about IBM Cognos Mobile user and report activity. For Audit logging level for mobile service, select any value except for Minimal.

  The following logging levels can be specified to enable audit logging: Basic, Request, Trace, and Full. The Minimal logging level disables audit logging.

• Question 33:

  An administrator must troubleshoot query execution related issues in a DQM executed report. How is this achieved?

  A. By default, settings to trace DQM Query execution are enabled in the system.

  B. Open IBM Cognos Configuration, under IBM Cognos Services/IBM Cognos, select QueryService and check Enable Query execution trace and view logs in /logs/XQE.

  C. Open IBM Cognos Administration portal, on the Configuration tab, select Dispatchers and locate QueryService and check Enable Query execution trace and view logs in /logs/XQE.

  D. Edit the install_location/configuration/qfs_config.xml.sample file and set , save as qfs_config.xml, restart services.

  Correct Answer: C

  A query execution trace (run tree trace) shows queries that run against a data source. You use the trace to

  troubleshoot query-related issues.

  You can find execution trace logs in the following location:

  c10_location/logs/XQE/reportName/runtreeLog.xml.

• Question 34:

  An administrator is implementing security by modifying access to the secured functions and secured

  features.

  Which statement is true?

  A. A hyperlink on the Capabilities page represents a secures function that contains secured features.

  B. Granting execute permission on a secured function automatically grants execute permission to all secured features.

  C. As part of the initial security implementation, an administrator must grant access to secured functions and features to the predefined roles.

  D. To view a list of the second functions and features available to them, a user must contact their administrator because only the administrator can perform this function.

  Correct Answer: B

  You set access to the secured functions and features by granting execute permissions for them to specified namespaces, users, groups, or roles.

  Incorrect Answers:

  C: When a content store is initialized, the initial permissions for the secured functions and features are created. The permissions define which of the predefined and built-in Cognos groups and roles have access to which secured functions and features, and the type of access. The initial permissions grant unrestricted access to IBM Cognos software because the built-in role System Administrators includes the group Everyone in its membership.

• Question 35:

  A report author gets the following error message:

  "An error has occurred. Please contact your administrator. The complete error has been logged by CAF with SecureErrorID:2004-05-25-15:44:11.296-#9."

  How can the administrator get the complete error message?

  A. Open the cogerror.log file using a text editor.

  B. Open the cogserver.log file using a text editor.

  C. Run the user report errors audit report from the samples Audit package.

  D. Run the user session details audit report from the samples Audit package.

  Correct Answer: B

  To find out about the actual error though an administrator with file access to the server log (cogserver.log)

  will need to search that log for the SecureErrorID given in the on-screen message.

• Question 36:

  After a user added numerous schedules, the Content Store database has been locked because some

  schedules contain invalid data.

  What can an administrator do, to prevent the system from being locked in the future?

  A. Restrict the ability to create schedules to the Administrator only.

  B. Select the delivery service inside IBM Cognos Configuration and set the schedule validation property to true.

  C. Make sure that every schedule created by a user will be verifies with the validation button inside the schedule mask.

  D. Go to the Dispatcher options, select Event Manager Service and set the advanced property emf.schedule.validation.enabled to true.

  Correct Answer: B

  In IBM Cognos Analytics, when numerous schedules are added or updated, the content store database

  can lock if the schedules contain invalid data. If you experience this problem, you can set an advanced

  property that validates schedule properties and disables invalid schedules.

  If the emf.schedule.validation.enabled property is set to true, schedule properties such as start date, end

  date, data types, and user account credentials are validated. Invalid schedules that are encountered are

  disabled, and details of the disabled schedules are logged in the log files.

  The default for this property is false. To enable schedule validation, set the property to true.

• Question 39:

  A CQM report successfully runs in another environment but fails in IBM Cognos Analytics. Environments are identical except for the versions.

  How could the issue be identified?

  A. Perform a UDA trace.

  B. Modify the ipfserverconfig.xml.

  C. Increase the logging level of the Query service.

  D. Restart the IBM Cognos Analytics service to eliminate all remaining BIBus processes.

  Correct Answer: B

  The method for performing a UDA trace is different in Cognos 10 to previous versions due to the removal of the Cognos Logging Console Program. This is specific to CQM datasources.

  Please follow these steps:

  1.

  Navigate to /configuration

  2.

  Rename ipfUDAclientconfig.xml.sample it to ipfclientconfig.xml

  3.

  Wait 30 seconds

  4.

  Now run any reports that you wish to use the trace on.

  5.

  After running the reports the trace will generate a file named "UDA_Trace.log" within / logs. The log name and location can be changed by the user by editing the ipfclientconfig.xml file.

  6.

  Rename ipfclientconfig.xml to ipfUDAclientconfig.xml.sample to turn off the tracing.

  This trace records all database activity so should be turned off as soon as the possible.

• Question 40:

  Which component stores and retrieves application data, including report specifications, report output, security, and configuration data?

  A. Gateway

  B. Dispatcher

  C. Content Manager

  D. Presentation service

  Correct Answer: C

  The Content Manager service: Performs object manipulation functions in the content store, such as add, query, update, delete, move, and copy Performs content store management functions, such as import and export To make printers available to users when they distribute reports, you can create entries for printers and save them in the IBM Cognos content store.

  Incorrect Answers:

  B: The dispatcher is the entry point for IBM Cognos service requests sent by a Web server gateway or other software. The dispatcher handles the routing requests and balances the load of user requests to the various IBM Cognos services.

  D: The Presentation service: Transforms generic XML responses from another service into output format, such as HTML or PDF Provides display, navigation, and administration capabilities in IBM Cognos Connection
