Which statement is true?

• A.The Service Guardian must be disabled for these longer EntryProcessors.
• B.The Service Guardian willprotect all of the applications EntryProcessor processes withoutdetecting any as stuck.
• 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 plan to deploy your Coherence application to a new production environment.

• A.Coherence MulticastTest
• B.Coherence DatagramTest
• C.Coherence Console
• D.Coherence CohQL Command-Line

• B.caching the results of the web service call with a configured expiration
• C.dynamically increasing the partition count on a running server
• D.dynamically adding Coherence cache servers to the cluster

When integrating a CacheStore with a database, which technique is correct for managing database connections?

• A.Create a new connection in the CacheStore constructor and store a to it that can be accessed by the CacheStore methods.
• B.Create a new connection every time a CacheStore method is invoked.
• C.Use a connection pool provided by an application server, the JDBC driver, or a third party.
• D.Configure Coherence to use its built-in capabilities to manage connections.
