What is the first step towards creating an appliance?

• A.introspection of a VM template
• B.fileset capture
• C.introspection of an installed system
• D.template creation

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 cache loader to maintain a "map" of entries not found, and consult this map before attempting to load an entry from the external source.
• B.This can't be achieved with Coherence.
• 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.Configure a "cache-miss-scheme" on the appropriate cache.

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

• A.ultimately attempt to run the object on a free worker thread associated with the service of the cache in which the object was placed
• B.immediately schedule it to be an on the service thread of the cache in which it was placed
• C.hand the object over to the Invocation service to invoke the run method
• D.do nothing; Coherence does not differentiate between types of value objects

You plan to deploy your Coherence application to a new production environment.
You want to ensure that the new environment supports multicast, and that all of the machines are connected to the same physical switch for optimal performance.
What two tools will help confirm that the new environment satisfies both criteria? (Choose two.)

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

You are using Coherence to store state data that gets read frequently and updated only occasionally. Only 100 or so clients are logged in at any time, and state data is retrieved at login. You are running out of physical memory on the cache server tier, but CPU and network utilization is low. You have 100 GB Solid-State Drives on every system, including clients. You would also like to provide faster access to state data for logged-in users.
Which configuration should you use for your system?

• A.Configure a near cache on your client and a Flash Journal on your cache servers.
• B.Configure Elastic Data on your clients with a near cache.
• C.Because near caching does not work with Elastic Data, configure a near cache and an eviction policy on the cache servers.
• D.Configure a near cache on your client and a RAM Journal on your cache servers.
