IBM C1000-178 Sample Questions:

01. In a distributed installation, users who run reports see CAF-WRN-2082 An error has occurred. Please contact your administrator. In cogaudit.log the administrator finds the underlying DPR-ERR-2072 Unable to load balance a request with absolute affinity. Data server connection tests succeed, and no dispatcher shares a port with the Dataset Service.

What should the administrator correct?

a) The queue time limit of the report service

b) Store symmetric key locally, set to True on each standby Content Manager

c) The IBM Cognos Application Firewall settings, with CAF validation enabled and every property identical on all dispatchers

d) The Dispatcher password under Environment, identical on every server and set first on Content Manager

02. An author runs a long list report as HTML with Include performance details and scrolls to the end. The Total Execution Time shown is far shorter than the time the same report takes when it is scheduled.

What explains the gap, and how can the author see the report's actual runtime?

a) Performance details omit the query service; read the Service time report

b) The last run reused cached query results; clear the query service cache and run it again

c) IPA truncates its records after 10 hours; run the report again straight after the scheduled run

d) Interactive HTML fetches rows as needed; raise Rows per page on the list

03. Reports that contain embedded GIF and JPG images show them in HTML output, but in PDF output only the borders of the images appear. The images are stored in a virtual directory on Microsoft IIS, and the security team will not allow anonymous access to that directory.

What should the administrator do?

a) Give the dispatcher's account access to the images' virtual directory

b) Move the Temporary files location to a disk with more free space

c) Clear the Enable the HTTP Keep Alives option in the web site's properties

d) Enable Windows authentication on the virtual directory that holds the images

04. The content store runs on PostgreSQL, and no Notification database is configured. The administrator is about to set up the Interactive Performance Assistant (IPA) for report authors.

What must be in place so that IPA writes its records to a supported database?

a) Nothing more, since IPA can write to PostgreSQL, Informix or any other content store type

b) A Notification database on Db2, Oracle or SQL Server

c) An IPADATA data source that points at the PostgreSQL content store

d) A logging database under Environment > Logging to receive the records

05. Scheduled reports owned by an employee who has left the company now fail with CNC-SDS-0413 There is a problem in executing the task. The user authentication failed. The employee's account has been removed from the directory server.

How should the administrator get the schedules running again?

a) Renew the trusted credentials of the former employee's account

b) Edit the data source signon, and let the schedules run as the database account

c) Log on as a valid user, schedule the reports under that account, and save the schedules

d) Enable a job and schedule monitor (JSM) trace

06. An administrator has set DISP.zipi.IPAEnabled to true. Because of heavy batch and email volume, the environment uses a separate Notification database. The DBA searches the content store database for tables with the IPA prefix and finds none.

What is the most likely explanation?

a) The tables are created when the IPA deployment is imported

b) IPA writes to the Notification database when one exists, so the tables are there

c) IPA stores its records in cogaudit.log until audit logging for the services is set to Request

d) The IPADATA data source has not been created yet, and creating it is what makes the tables

07. When an administrator opens IBM Cognos Configuration, it reports that the configuration data is locked by another instance of IBM Cognos Configuration. No other instance is running; the previous session ended when the server lost power.

What should the administrator do?

a) Delete the cogstartup.lock file in the install_location/configuration directory

b) Stop the IBM Cognos service

c) Delete the cogstartup.xml file and restore it from the most recent configuration backup

d) Run cogconfig.sh -s to release the lock

08. Each night an administrator backs up the content store database with the database vendor's tools and copies the install_location/configuration directory. Some time ago the encryption and signing key settings were moved away from their default location, and the key stores are protected with passwords. The server must be recoverable on the same computer after a disk failure.

Which two further items must the backup plan cover?

(Choose two.)

a) The directory that now holds the encryption and signing keys

b) The Temporary files location and the session output kept in it

c) An encrypted deployment archive of the entire content store

d) The passwords that secure the key stores

09. Testing a new JDBC data server connection returns DPR-ERR-2072 Unable to load balance a request with absolute affinity, most likely due to a failure to connect to the remote dispatcher.

Which three conditions are documented causes of this error?

(Choose three.)

a) The dispatcher and the Dataset Service are configured with the same port

b) The query service or the metadata service is not started

c) A firewall blocks network traffic to the database server

d) The Content Manager computers' system clocks are not synchronized

10. Very large PDF outputs from Dynamic Query Mode packages run out of memory while they are rendered. The environment also serves packages based on IBM Cognos PowerCubes and has three 64-bit Application Tier Components instances on 64-bit computers.

Which configuration meets both needs?

a) Use 64-bit on two instances, keep one at 32-bit and route PowerCube reports to it

b) Raise the JVM heap size limit for the query service on each of the three instances

c) Keep all three instances at the default 32-bit report server execution mode

d) Set Report server execution mode to 64-bit on all three instances and restart them
