質問 5：
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. Configure a "cache-miss-scheme" on the appropriate cache.
B. 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.
C. This can't be achieved with Coherence.
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.
正解：B
