Your application is configured to use Service Guardian with default settings to protect against stuck service threads. The application runs a set of EntryProcessors to perform various types of calculations. These calculations can take a few milliseconds, but occasionally take up to 30 minutes to process.

Which statement is true?

A. The Service Guardian willprotect all of the applications EntryProcessor processes withoutdetecting any as stuck.

B. The Service Guardian must be disabled for these longer EntryProcessors.

C. The Service Guardian does not protect threads running user code like EntryProcessors.

D. The EntryProcessor must issue manual heartbeats to the Service Guardian or risk being killed.

You notice the following message in one of your cache server logs:

Which statement correctly explains this message?

A. Member 102 received a MemberLeft message from the senior member (member 1) that member 74 has left the cluster.

B. Member 1 received a MemberLeft message from the senior member (member 74) that member 102 has left the cluster.

C. Member 1 received a MemberLeft message from the senior member (member 102) that member 74 has left the cluster.

D. Member 74 received a MemberLeft message from the senior member (member 1) that member 102 has left the cluster.

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.

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?

A. Introduce a near cache for all partitioned caches.

B. Increase the size of the thread pool for all cache services.

C. Increase the expiry delay on all distributed-scheme backing maps.

D. Lower the high-unit threshold on all distributed-scheme backing maps.

What two sources can be used to provision a WLS domain? (Choose two.)
