Which is a valid reason for using Coherence Elastic Data?

• A.You want to extend your cluster across a WAN.
• B.You want to cache more that the total amount of RAM on your systems.
• C.You want to store data on very large heaps.
• D.Data must be persisted to disk to ensure fault tolerance.

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.

• A.Coherence Grid Edition, with the compute grid clients being storage-disabled Coherence cluster members.
• B.Coherence Standard Edition. Nothing special is needed and Standard Edition is the low- cost option.
• C.Coherence Enterprise Edition, with the compute grid running against a set of Coherence*Extend proxies and continuous query cache on Coherence*Extend clients.
• D.Coherence Enterprise Edition, with the compute grid clients being storage-disabled cluster members.

A company relies on third-party web services for data.
Which two Coherence features can be applied to shield its customers from anticipated spikes in demand of the web services, without suffering potential performance degradation? (Choose two.)

• A.caching the results of the web service call with a configured expiration
• B.configuring an overflow scheme so that spikes are handled gracefully
• C.dynamically adding Coherence cache servers to the cluster
• D.dynamically increasing the partition count on a running server

Which three areas are automatically optimized by the Oracle JDK ergonomics? (Choose three.)

• A.Runtime compiler
• B.Heap size
• C.Debugging options
• D.Garbage Collector
• E.Class loader

An application frequently requests data (from s Coherence cache configured with a cache loader) that may not be available in the underlying data source. The cost of looking up data via the cache loader is expensive in terms of time and resources.
To reduce these costs, which configuration should be used to cache the notion that an entry is not available?

• A.This can't be achieved with Coherence.
• B.Configure a "cache-miss-scheme" on the appropriate cache.
• C.Modify the application to maintain a "misses" cache to keep track of the entries that were expected to be found in the other cache, but were recently not found.
• D.Modify the cache loader to maintain a "map" of entries not found, and consult this map before attempting to load an entry from the external source.
