Consider an application using a Coherence partitioned cache to store HTTP session data.
There is a load balancer that performs client based affinity (or "sticky load balancing"), meaning that requests that come from a particular user will be routed to the same application server every time. Most user requests will read from the session, thus making near caching topology a good fit.
Which near cache configuration matches the requirements for this application?

Your application had experienced an OutOfMemoryError on one of the cache servers. You had configured the JVM to produce a heap dump when OutOfMemoryErrors occur. Your analysis of the heap dump indicates that approximately 90% of the heap is consumed by instances of com.tangosol.util.Binary.
What configuration change will reduce the number of com.tangosol.util.Binary instances?

After going through a sizing exercise, you determine that your application will need 100 storage-enabled JVMs with 4 GB heaps. You have 10 physical machines with 16 cores and 32 GB of RAM.
Which performance-tuning best practice would be violated by deploying your application on these machines?

Your customer is a financial services company that uses a large compute grid (not Coherence) to do risk calculations. Objects representing risk scenarios are cached in Coherence. When these objects are updated, they are sent to the compute grid to recalculate risk via a continuous query cache. Assume that there are 100 compute servers in one data center and 100 GB of cached data. The customer is not worried about potential cluster instability, given their network design.
Which solution supports the customer's requirements? Keep in mind licensing costs and features by edition.
