Question 1

To monitor performance, an administrator has set thresholds on a system metric and notices that over time, the metric score has changed from green, to yellow, to red, and then back to yellow.

Which system metric is the administrator monitoring?

ADispatcher: JVM: Current heap size

BContentManageService: Request: Number of failed requests

CReportService: Process: Number of processes high watermark

DBatchReportService: Request: Percentage of successful requests

Correct : B

Question 2

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?

ARestrict the ability to create schedules to the Administrator only.

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

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

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

Correct : B

InIBM 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 3

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?

AOpen the cogerror.log file using a text editor.

BOpen the cogserver.log file using a text editor.

CRun the user report errors audit report from the samples Audit package.

DRun the user session details audit report from the samples Audit package.

Correct : 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 4

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

Which statement is true?

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

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

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

DTo 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 : B

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

Question 5

A high user load and interactive reporting system on a distributed installation is throwing timeout error messages.

How is this resolved?

AIncrease the JVM heap settings in IBM Cognos Configuration under Services.

BEdit the install_location/bin CQEConfig.xml and change the DB_Connection_Pool value to 120, save and restart the service.

CEdit the install_location/webapps/p2pd/WEB-INF/services reportservice.xml and increase the async_wait_timeout_ms, save and restart the service.

DIncrease the number of Report Processes under IBM Cognos Administration on the Status tab under System, set properties to equal 2 times the number of total processor cores.

Correct : C

Increase Asynchronous Timeout in High User Load Environments.

If you have a high user load (over 165 users) and interactive reports are running continuously in a distributed installation, you may want to increase the asynchronous timeout setting to avoid getting error messages. The default is 30000.

To resolve this problem, increase the wait timeout.
