• Question 2:

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

• Question 3:

  What three operations can an EM_PROVISIONONG_DESIGNER perform that an EM_PROVISIONONG_OPERATOR cannot? (Choose three.)

  A. Create profiles, components, and directives in the Software Library.
  B. Access provisioning profiles in the Software Library.
  C. Customize the default deployment procedure.
  D. Create deployment procedure templates.
  E. There is no difference in the type of operations that these two users can perform.
  A. Create profiles, components, and directives in the Software Library.
  C. Customize the default deployment procedure.
  D. Create deployment procedure templates.

• Question 4:

  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?

  A. Heap sizes should not be larger than 512 MB.
  B. OS socket buffers should be at least 2 MB.
  C. Avoid OS memory swapping/paging by not exhausting physical RAM.
  D. Do not exceed one JVM per core.
  B. OS socket buffers should be at least 2 MB.

  B. SOA Composites
  C. WLS Domains
  D. WLS Managed Servers
  E. Oracle ESB
  A. Applications Deployments
  B. SOA Composites

• Question 6:

  How many appliances can you deploy as part as an assembly?

  A. only one
  B. one to three
  C. one to five
  D. There is no predefined limit
  C. one to five

• Question 7:

  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.
  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.

• Question 8:

  What agent is used to collect the WLS server metrics that are available on the WLS All Metrics page?

  A. ADP Agent
  B. JVM Diagnostics Agent
  C. BTM Agent
  D. EM Agent
  E. JVMD Agent
  B. JVM Diagnostics Agent

• Question 9:

  What three components are not part of EM and require separate installations? (Choose two.)

  A. BTM Engine
  B. RUEI Engine
  C. JVM Diagnostics Engine
  D. Application Discovery and Performance Management Engine
  E. Ops Center
  D. Application Discovery and Performance Management Engine
  E. Ops Center

• Question 10:

  A customer is witnessing a lot of contention while accessing and updating a cached item.

  Which feature alleviates the connection by shortening the time that the object is locked?

  A. Near Cache
  B. Entry Processors
  C. Transaction Framework
  D. off-heap storage
  C. Transaction Framework
