An administrator has a requirement to specify system-wide accessibility settings for all entries (reports, jobs and schedules).
How can this be done?

  1. No action needed as the Administrator has access to all entries by default.
  2. In IBM Cognos Portal select all entries and change owner to Administrator.
  3. In IBM Cognos Administration, on the Deployment tab add a new deployment, select full Content Store and deploy without security and import overriding Source with Administrator user.
  4. In IBM Cognos Administration, click on “configuration” > dispatchers and services > click on “set properties” > click on “settings” > in the Category drop down list box select
    “Administrator Override”.

Answer(s): D

Explanation:

Enable Accessible Report Output Using System-wide Settings
Accessible reports contain features, such as alternate text, that allow users with disabilities to access report content using assistive technologies, such as screen readers. In IBM Cognos Administration, you can specify system-wide settings for accessible report output that apply to all entries, including reports, jobs, and scheduled entries.

Accessibility settings in the user preferences and report properties can overwrite the system-wide settings in IBM Cognos Administration.

An environment is configured to use Compatible Query Mode (CQM). Which statement is true about request flow?

  1. OLAP, DMR and Relational components reside in the same Adapters layer.
  2. OLAP, UDA and DMR components reside in the same Query Execution layer.
  3. OLAP, Relational and DMR components reside in the same Query Planning layer.
  4. OLAP, DMR and Relational components reside in the same Query Execution layer.

Answer(s): C

Explanation:

OLAP style queries, like those against SAP BW, Oracle Essbase and IBM Cubing Services type data sources, will go to the OLAP query planner.

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?

  1. Restrict the ability to create schedules to the Administrator only.
  2. Select the delivery service inside IBM Cognos Configuration and set the schedule validation property to true.
  3. Make sure that every schedule created by a user will be verifies with the validation button inside the schedule mask.
  4. Go to the Dispatcher options, select Event Manager Service and set the advanced property emf.schedule.validation.enabled to true.

Answer(s): B

Explanation:

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.

An administrator is creating a datasource for an IBM Cognos PowerCube. On the datasource creation page, the ‘Configure JDBC connection’ check box is played out and cannot be selected.
What is the reason for this?

  1. The IBM Cognos PowerCube is not optimized.
  2. The execution mode for the dispatcher is not set to 64 bit.
  3. The execution mode for the environment is not set to 64 bit.
  4. JDBC connection is not supported for IBM Cognos PowerCube.

Answer(s): B

Explanation:

Compatible query mode
To run reports that use the compatible query mode, you must use 32-bit data source client libraries and configure the report server to be 32-bit. The compatible query mode uses native client and ODBC connections to communicate with data sources.
If the data source is 64-bit, ensure that you use the 32-bit client libraries to connect to the data source to use the compatibility query mode.
