IBM IBM Certifications C2090-623 Questions & Answers

• Question 51:

  All users have unrestricted access in a secured environment. What must be modified to control this access?

  A. Delete the "All Authenticated Users" group.

  B. Disable anonymous access using IBM Cognos Configuration.

  C. Modify the advanced properties of the authorization namespace.

  D. Remove the "Everyone" group from the "System Administrators" role.

  Correct Answer: B

  You can disable the Anonymous user account by changing the configuration parameters in the configuration tool. This entry represents a user account shared by members of the general public who can access IBM Cognos software without being prompted for authentication. For example, this type of access is useful when distributing an online catalog. Anonymous users can see only those entries for which access permissions are not set, or are set specifically for this account or for the Everyone group.

  Incorrect Answers:

  A: The built-in entries include the Anonymous user account, the groups All Authenticated Users and Everyone, and the role System Administrators. You cannot delete the built-in entries. They appear in both secured and non-secured environments.

• Question 52:

  An environment has the following routing rules set:

  

  If a report using the `Australia Package' is run by a user belonging to `Australia Group', which server group will the request be sent to?

  A. Group 1

  B. Group 2

  C. The request will be sent to the first available server because there is more than one rule for the Australia Package.

  D. The request would fail because there is more than one rule for the Australia Package and only one for the Australia group.

  Correct Answer: B

  Unlike routing keywords, the order in which the routing rules are listed affects how they are applied. A rule is matched when properties associated with the package or the group or role involved in the request satisfy the criteria of the rule. The rules are evaluated in order until the first one is matched, and the request is routed to the server group named by the first rule that was matched. You can change the order of the rules by clicking Modify the sequence.

• Question 53:

  An administrator wants to render a report and ensure the completed HTML is sent back to the gateway.

  Which service is responsible for the rendering task?

  A. Report service

  B. Delivery service

  C. Presentation service

  D. Content Manager service

  Correct Answer: C

  The Presentation service Transforms generic XML responses from another service into output format, such as HTML or PDF Provides display, navigation, and administration capabilities in IBM Cognos Connection

  Incorrect Answers:

  A: The Report service manages interactive requests to run reports and provides output for a user in IBM Cognos Connection or a studio.

  B: The Delivery service sends emails to an external SMTP server on behalf of other services, such as the report service, job service, agent service, or data integration service

  D: The Content Manager service: Performs object manipulation functions in the content store, such as add, query, update, delete, move, and copy Performs content store management functions, such as import and export

• Question 54:

  An administrator wants to ensure that a datasource can be referenced when creating data modules in the

  IBM Cognos Analytics Portal (New > Data module).

  What must be done to accomplish this?

  A. Add the datasource to the list of supported datasources in IBM Cognos Configuration.

  B. Configure the datasource in IBM Cognos Transformer so that it can communicate with the portal.

  C. In the web-based modeling tool itself, specify the `Create Data Modules' access permission for the datasource.

  D. On the Connection tab of the datasource properties, ensure that the `Allow web-based modeling' check box is selected.

  Correct Answer: D

  Problem(Abstract): Datasource connections not listed in Data server by default

  Symptom: We can see the datasource in the Admin console but not in the list of data servers.

  Cause: This is default behavior.

  Resolving the problem

  Go to the Administrative Console -> Configuration -> Set properties -> Connections tab.

  On the bottom, you will see "Data source capabilities"

  Inside that, check the box which says "Allow web-based modeling"

  Once you check this, the datasource would be present as data server.

• Question 55:

  An administrator wants to exclude Request level logging details from being captured. Which logging level must be set?

  A. Basic logging level

  B. Trace logging level

  C. Verbose logging level

  D. Request logging level is turned on by default

  Correct Answer: A

  The higher you set the logging level, the more it degrades system performance. Normally, you set the level to Minimal or Basic to collect errors, or to Request to collect errors and warnings.

  Note: Report validation levels and logging levels Report validation level, Logging level Error: Minimal, Basic Warning: Request Key Transformation: Trace Information: Full

• Question 56:

  An administrator is implementing security by managing and working with the Cognos namespace. Which statement is true?

  A. To gain access to IBM Cognos Analytics, users can log on to the Cognos namespace.

  B. Create domain users in the Cognos namespace to avoid cluttering the existing authentication provider.

  C. User-defined groups and roles must be created in a 3rd-party authentication provider and cannot be created in the Cognos namespace.

  D. Although the use of the predefined and built-in groups and roles within the Cognos namespace is optional, the Cognos namespace cannot be deleted.

  Correct Answer: D

  The Cognos namespace includes predefined objects to help you quickly set up initial security.

  You use the predefined objects and other features of the Cognos namespace for ongoing security

  management.

  You can create groups and roles in the Cognos namespace.

  Initial access permissions are applied to all predefined objects. You can modify the permissions from the

  object properties.

• Question 57:

  An environment has twenty dispatchers. The administrator wants to change one property to the same

  value for all dispatchers.

  How can that be accomplished?

  A. This can be accomplished if all dispatchers are put inside a folder.

  B. This can be accomplished by changing the desired property for the configuration.

  C. This cannot be accomplished unless the property value is changed for each dispatcher.

  D. This can be accomplished by selecting all dispatchers at once and changing the desired property.

  Correct Answer: A

  Grouping dispatchers in configuration folders.

  Configuration folders are useful to organize dispatchers if your installation includes many dispatchers. You

  can group dispatchers so that you can apply the same configuration settings once to all the dispatchers

  and services in the folder.

  Note: You can have more than one dispatcher in your IBM Cognos environment. In such distributed

  installations one dispatcher is configured for every instance of the Content Manager or Application Tier

  Components that are installed and configured in your environment.

• Question 58:

  An administrator is evaluating system status using the Scorecard pane on the Status > System page in the

  IBM Cognos Administration console.

  Which statement is true?

  A. If a service is disabled in IBM Cognos Configuration, it is listed in the Scorecard pane.

  B. The status that is displayed for each entry reflects the lowest status for all child entries.

  C. A status of Available is displayed when at least 80% of the child entries have a status of Available.

  D. A status of Unavailable is displayed when at least 80% of the child entries have a status of Unavailable.

  Correct Answer: B

  The metric score for each entry is based on the performance of individual child entries. The status that is displayed for each entry is the lowest status of the child entries. For example, if all the metrics for a dispatcher are good, but one service on that dispatcher has a poor metric, the metric score shown for the dispatcher is poor.

  Status is one of the following: Available if all components are available Partially available if at least one component is available and at least one component is unavailable or partially unavailable. Unavailable if all components are unavailable

• Question 59:

  An administrator sees that an environment has a long startup time and wants to remedy the issue.

  Which solution should be used?

  A. Set load balancing to cluster compatible.

  B. Check the Fast Startup option under IBM Cognos Configuration.

  C. Increase the size of the JVM heap by selecting Large configuration.

  D. Reduce the size of the Content Store through archiving and removal.

  Correct Answer: A

  If your IBM Cognos servers operate within a load balancing infrastructure, you can turn off the weighted round robin format of load balancing for the dispatcher. Otherwise, load balancing may be duplicated by the cluster and by IBM Cognos software, which can degrade performance. You can set the dispatcher property named loadBalancingMode either to weightedRoundRobin or clusterCompatible.

  A. capacity, scalability, availability

  B. gateways, application servers, Content Manager

  C. IBM Cognos implementation, capacity, infrastructure

  D. infrastructure, gateways, application servers, scalability

  Correct Answer: C

  Conduct an architecture review to assess the physical architecture and software installation. References: ftp://public.dhe.ibm.com/software/pdf/dk/service-shop/ IBM_Cognos_BI_Health_Check_Service_FINAL_10-21-11.pdf
