Correct answer: Add the file paths to the preserve.txt file in the configuration folder.

The `preserve.txt` file located in the `configuration` folder is specifically used to list files and directories that should not be overwritten during an upgrade. The installation process checks this file and backs up the listed items before installing new files, then restores them. While `preserve.xml` exists, it is generally for internal system use, whereas `preserve.txt` is the user-configurable allowlist for custom files.

Correct answer: xqe.config.xml

For Dynamic Query Mode (DQM), the configuration is controlled by `xqe.config.xml`. To pass application context (like user info and report names) to the database, parameters are set within this file. `CQEConfig.xml` is used for the Compatible Query Mode (CQM). `cogstartup.xml` is for general service startup configuration.

Correct answer: Redirect URI template

When configuring OIDC, the Identity Provider sends the authentication token back to a specific URI. In Cognos Configuration, under the OIDC namespace properties, the 'Redirect URI' property is automatically generated based on the configuration but usually defaults to `https:// : /bi/v1/auth/v1/signin`. This exact value must be registered in the IdP's allowed redirect URIs list. If they mismatch, the IdP rejects the request.

Correct answer: ./ca_instl_linux_3.8.bin -f installer.properties

To run a silent installation on Linux, the installer binary is executed with the `-f` flag followed by the path to the response file (properties file). The `-i silent` flag is also often implied or required depending on the exact version wrapper, but the `-f` flag is critical for pointing to the configuration properties.

Correct answer: Dispatcher

The Dispatcher is the entry point for service requests within the Cognos application tier. It contains a router that directs requests to the appropriate local service (like Report Service, Batch Service) or forwards them to a dispatcher on another computer if necessary. The Gateway sits outside the application tier and handles web communication, passing requests *to* the Dispatcher.

Correct answer: Ensure the 'External dispatcher URI' is set to a publicly accessible URL or accessible via VPN/Gateway.

For mobile devices to connect, the `External dispatcher URI` in Cognos Configuration must be reachable from the mobile device. If devices are outside the firewall, this often involves a reverse proxy or gateway, and the URI must resolve correctly from the external network context.
