In a LifeCycle Manager Project, a user can create either a Benchmark task or a Comparison task. Which statement is INCORRECT when describing the…

A Benchmark task in IBM Cognos LifeCycle Manager is designed to create a baseline by capturing the output and performance metrics of reports from a source environment in their current state. The option to force reports to run in Dynamic Query Mode (DQM) is a specific setting within a Comparison task, not a Benchmark task. This allows a user to compare the output of reports running in DQM on a target server against the established benchmark, which typically represents the original Compatible Query Mode (CQM) output from the source server. Therefore, the ability to choose DQM execution is not a feature available during the creation of a Benchmark task itself.

A. A benchmark creates a reusable baseline. This baseline can indeed be selected as the source for comparison tasks in any LifeCycle Manager project.

B. This describes a primary use case for LifeCycle Manager: establishing a CQM benchmark to validate the output and performance after migrating reports to DQM.

D. This accurately describes the process of setting up a Comparison task, where a pre-existing Benchmark task is selected as the source for comparison against a target server.

1. IBM Cognos LifeCycle Manager 10.2.2 User Guide, Chapter 4: Working with tasks, Section: "Creating a comparison task", p. 25. This section details the properties for a comparison task and explicitly lists the "Run reports in dynamic query mode" checkbox as an available option. The corresponding section, "Creating a benchmark task" (p. 23), does not include this option.

2. IBM Documentation for IBM Cognos Analytics 11.1.7, Section: Managing > Validating and comparing report outputs > Creating a comparison task. The documentation states, "To run the reports in dynamic query mode, select the Run reports in dynamic query mode check box." This option is documented exclusively for comparison tasks.

3. IBM Documentation for IBM Cognos Analytics 11.1.7, Section: Managing > Validating and comparing report outputs > Creating a benchmark task. This document outlines the steps and properties for creating a benchmark task. The option to run reports in Dynamic Query Mode is notably absent from the available settings, confirming it is not a feature of this task type.
