An administrator needs to address an environment that is not running optimally and conduct an architecture review.
Which performance attributes should be considered?
Conduct an architecture review to assess the physical architecture and software installation.
An administrator sees that an environment has a long startup time and wants to remedy the issue.
Which solution should be used?
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.

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?
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:
An environment has twenty dispatchers. The administrator wants to change one property to the same value for all dispatchers.
How can that be accomplished?
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.
An administrator is implementing security by managing and working with the Cognos namespace.
Which statement is true?
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.
