  • C: Thread deadlock analysis is not possible in Flight Recorder.
  • D: Flight Recorder cannot be run in an "always-on" mode.
  • E: Flight Recorder causes significantly higher processor overhead than Runtime Analyzer.

Question 4
When an object placed into a cache implements the Java Runnable interface, Coherence will _______________.

  • A: immediately schedule it to be an on the service thread of the cache in which it was placed
  • B: do nothing; Coherence does not differentiate between types of value objects

Question 6
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: 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.
  • B: Configure a “cache-miss-scheme” on the appropriate cache.
  • C: 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.
  • D: This can't be achieved with Coherence.

Question 7
Which system property is used to customize a Coherence deployment configuration for different environments?

  • A: tangosol.coherence.cacheconfig
