C1000-065 Exam Dumps - IBM Certified Developer - Cognos Analytics V11.1.x Questions and Answers

Interactive Performance Assistant: This tool in IBM Cognos Analytics V11.1.x provides real-time performance monitoring and analysis for reports.

Enabling the Assistant: By enabling the interactive performance assistant, users can gather detailed performance metrics as the report runs, which helps identify bottlenecks and areas for optimization.

Benefits: This tool provides insights into query execution times, rendering times, and resource usage, enabling developers to make informed decisions to improve report performance.

Reference: The IBM Cognos Analytics V11.1.x documentation outlines how to enable and use the interactive performance assistant for investigating and improving report performance.

Cognos Analytics Data Set: A data set in Cognos Analytics is an extract from a package or data module.

Storage and Refresh: These extracts are compressed, stored locally, and can be refreshed either periodically or manually, depending on the requirements.

Use Case: Data sets are used to improve performance by reducing the need for repeated database queries and enabling offline access to the data.

Reference: IBM Cognos Analytics V11.1.x documentation details the nature of data sets, highlighting their extraction process, storage, and refresh capabilities for enhanced performance and usability.

To create a data module on a data server after upgrading from Cognos version 10, follow these steps:

Access Administration Console: Log into the IBM Cognos Administration Console.

Navigate to Data Source Connection: Go to the "Configuration" tab and select "Data Source Connections".

Edit Data Source: Choose the data source connection that you want to enable for web-based modeling and click "Edit".

Enable Web-Based Modeling: In the data source connection properties, there will be an option to "Allow web-based modeling". Check this option to enable it.

Save and Test: Save the changes and test the connection to ensure that web-based modeling is enabled.

Enabling web-based modeling allows users to create and manage data modules directly within the Cognos web interface, leveraging modern data modeling capabilities.

Conditional Block: This feature allows for dynamic content within reports based on user interactions and selections.

Prompt Selections: By using a conditional block, report developers can control the visibility of report objects based on the prompt values selected by the user at runtime.

Use Case: This is useful for creating reports that adapt to user inputs, providing a more tailored and relevant data presentation.

Reference: IBM Cognos Analytics V11.1.x documentation details how to implement conditional blocks to show or hide report objects dynamically based on user inputs.

Insights Feature: When Insights are turned on in IBM Cognos Analytics V11.1.x, the system generates various statistical and analytical outcomes depending on the selected visualization.

Generated Outcomes: These include:

Average: Calculates the mean value of the data set.

Predictive Strength: Indicates the strength of the predictive relationship between variables.

Fit Line: A trend line that best fits the data points in the visualization.

Meaningful Difference: Highlights statistically significant differences within the data.

Most Frequent Values: Identifies the most common values in the data set.

Cognos Documentation: The IBM Cognos Analytics V11.1.x documentation details the Insights feature, explaining how these various outcomes are derived and how they can be used to enhance data analysis and decision-making.

When the Drill-through target type is set to Bookmark in IBM Cognos Analytics V11.1.x, the following types of saved report outputs can be used:

HTML:

Interactive Output: HTML outputs are interactive and support bookmarks, allowing users to navigate to specific sections within the report.

Usability: Ideal for web-based viewing and interaction.

PDF:

Static Output: PDF outputs support bookmarks and provide a static, paginated format that is useful for printing and sharing.

Accessibility: Bookmarks in PDFs enhance navigation within long documents.

These output types leverage the bookmark functionality to improve navigation and user experience.

Local Filters: These allow developers to filter data at the visualization level, providing flexibility in data presentation without altering the underlying data source.

Keep/Exclude Data Points: This feature enables developers to interactively refine the data displayed in a visualization by keeping or excluding specific data points directly within the dashboard.

Cognos Documentation: The IBM Cognos Analytics V11.1.x documentation provides detailed instructions on creating local filters and using interactive filtering options to enhance the user experience in dashboards.

Layout Component Reference: This feature in IBM Cognos Analytics allows developers to reference existing report objects within the same report or across different reports.

Reuse for Consistency: By referencing existing components, developers ensure consistency in design and functionality across multiple reports.

Efficiency: This method reduces the effort needed to recreate similar report objects and facilitates easier maintenance and updates.

Reference: According to IBM Cognos Analytics V11.1.x documentation, Layout Component References are intended to streamline report development by allowing the reuse of report objects, thereby enhancing consistency and efficiency.
