Installation and Configuration · Connect Cognos to Authentication Providers
An administrator is configuring a new OpenID Connect (OIDC) authentication namespace in Cognos Configuration. After entering the Discovery Endpoint and Client ID, the connection test fails. The logs indicate that the redirect URI sent by Cognos does not match the URI registered in the Identity Provider (IdP). Which Cognos Configuration setting must match the redirect URI registered in the IdP?
Show answer & explanation
Correct answer: A
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. - Question 2Intermediate
Installation and Configuration · Install Cognos, single server vs distributed
A large organization requires a silent installation of Cognos Analytics on multiple Linux servers. The administrator has generated a response file named
installer.properties. Which command syntax correctly initiates the silent installation using this response file?Show answer & explanation
Correct answer: B
To run a silent installation on Linux, the installer binary is executed with the
-fflag followed by the path to the response file (properties file). The-i silentflag is also often implied or required depending on the exact version wrapper, but the-fflag is critical for pointing to the configuration properties. - Question 3Beginner
Installation and Configuration · Understand the different Cognos components
Which of the following components is primarily responsible for managing the routing of requests to the appropriate services in a distributed IBM Cognos Analytics environment?
Show answer & explanation
Correct answer: C
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.

Installation and Configuration · Configure mobile access
An administrator needs to configure IBM Cognos Analytics to allow users to access reports on mobile devices outside the corporate firewall securely. Which component configuration is specifically required to enable the IBM Cognos Mobile service to communicate effectively through the firewall?
Show answer & explanation
Correct answer: B
For mobile devices to connect, the
External dispatcher URIin 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. - Question 5Advanced
Installation and Configuration · Configure web server for Cognos
You use Microsoft IIS with Application Request Routing (ARR) as the gateway for IBM Cognos Analytics, and you want to integrate Cognos Analytics for Jupyter Notebook Server, whose notebooks use WebSocket connections. What does IBM require you to configure in IIS so that the notebook WebSocket traffic works?
Show answer & explanation
Correct answer: C
IBM's procedure for configuring IIS as the Cognos Analytics gateway uses Application Request Routing with reverse proxy rules to send REST and other server requests to the Cognos Analytics servers. Cognos Analytics for Jupyter Notebook uses WebSocket connections between the Jupyter Notebook Server and the browser. The Cognos Analytics services layer can proxy http and https traffic to the Jupyter server but cannot broker WebSocket requests, so notebook WebSocket requests must bypass it. For an IIS gateway, IBM therefore says to install WebSocket Protocol support in IIS (available in IIS 8.0 and later) and add a URL Rewrite rule that maps the notebook WebSocket requests (the v1/jupyter kernel channel URLs) directly to the Jupyter Notebook Server. Disabling the reverse proxy would break the gateway, because IBM's rules depend on it. IBM sets the server farm proxy Time-out to 120 seconds, and a shorter time-out makes long requests fail with HTTP 502 errors. Sending the WebSocket requests through the Cognos Analytics services layer is exactly what does not work.
