4. An administrator wants to implement load balancing without using an external load balancing mechanism.
What is one approach that can be used to achieve this?
A. Set up a standby Content Manager.
B. Install a gateway on each database server.
C. Configure dispatchers together with the content stores.
D. Configure gateways to direct all traffic to a dedicated dispatcher.
Answer: C
Explanation:
If your installation includes more than one dispatcher, you can specify the proportion of requests that each dispatcher handles by changing their processing capacity. This is commonly referred to as load balancing. You typically set the capacity for a dispatcher based on the CPU speed of the computer where it is installed.

6. 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.
Answer: A
Explanation:
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.
