What is the main method used to collect the monitoring data of a Coherence cluster, its nodes, and caches?

  1. Enterprise Manager agent on every host, querying JMX data from nodes running on that host

  2. one central Enterprise Manager agent, querying JMX data from each node in the cluster

  3. JVMD agent collecting data trough sampling of the JVM for each node

  4. Enterprise Manager agent on every host, querying JMX data from nodes running on the host, and a central Enterprise Manager agent querying JMX data from a management node for cluster-level

  5. one central Enterprise Manager agent querying JMX data from a single management node

Question No: 14

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?

  1. 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.

  2. Configure a “cache-miss-scheme” on the appropriate cache.

  3. 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.

  4. This can#39;t be achieved with Coherence.

Answer: A

Question No: 15

After going through a sizing exercise, you determine that your application will need 100 storage-enabled JVMs with 4 GB heaps. You have 10 physical machines with 16 cores and 32 GB of RAM.

Which performance-tuning best practice would be violated by deploying your application on these machines?

  1. Heap sizes should not be larger than 512 MB.

  2. OS socket buffers should be at least 2 MB.

  3. Avoid OS memory swapping/paging by not exhausting physical RAM.

  4. Do not exceed one JVM per core.

Answer: B

Question No: 16

Question No: 17

Which statement about JRockit Discovery Protocol (JDP) is true?

  1. JDP enables network auto discovery of JVMs.

  2. JDP is a subset of HTTP.

  3. JDP can be used by application to exchange serialized data between JVMs.

  4. JDP was initially introduced in the HotSpot VM 1.5.

Answer: A

Question No: 18

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

  1. Use a connection pool provided by an application server, the JDBC driver, or a third party.

  2. Create a new connection every time a CacheStore method is invoked.

  3. Create a new connection in the CacheStore constructor and store a to it that can be accessed by the CacheStore methods.

  4. Configure Coherence to use its built-in capabilities to manage connections.

Answer: A

Question No: 19
