Consider the following code: If the initial stock amount was 15, and 5 different clients (in different JVMs) attempted to execute the same code simultaneously, what would be the resulting level of stock?

• AA. 20, because Coherence does implicit locking
• BB. 15, because a concurrency control exception will be thrown

Which two mechanisms are explicitly monitored to determine death of a cluster member? (Choose two.)

Select 2 answers.

• AA. garbage collection

An Oracle RAC Database appliance was initially deployed with two database instances. The load on the database has now increased and another instance needs to be provisioned. How would you add one more instance of the earlier deployed appliance?

• AA. Create and deploy a new assembly containing a single instance database appliance.
• BB. Add a new single instance database appliance into the previously created assembly and redeploy it.
• CC. Use the ScaleAppliance operation to scale up the deployed appliance instances from two to three.
• DD. Use the createAssemblyInstance operation to create a new instance of the existing assembly and deploy the new assembly instance.

Which two statements are true about minor or young garbage collections? (Choose two.)

Select 2 answers.

• AA. Minor garbage collection is triggered when the eden space is full.
• BB. Minor garbage collection does not cause a stop the world operation.
• CC. Permanent generation is included in minor garbage collection.
• DD. Minor garbage collections are usually shorter, with minimal impact on performance.
• EE. Minor garbage collection does not occur when using a parallel collector.

Which change cannot be made in an assembly at deployment time?

• AA. setting the appliance’s memory and CPU requirements
• BB. changing the listening port of the product
• CC. not deploying an appliance by setting its target count to zero
• DD. not deploying an appliance by removing it from the assembly

A company has a billing and ordering application accessed by ten million subscribers. Some subscribers rarely log in, and others log in almost every day. The company's goal is to provide the quickest possible response to web requests. Accesses make repeated reads and occasional writes to user sessions, each of which is 4 KB. Which architecture meets these needs?

• AA. a replicated cache, so that applications can always access data locally
• BB. there is too much data for Coherence to be effective in this scenario
• CC. a distributed cache with sticky sessions and near caching
• DD. a small replicated cache for frequent users and database read-through

Which two JVM components can be configured to impact application performance? (Choose two.)

Select 2 answers.

• AA. Heap
• BB. Local variables stack
• CC. Class loader
• DD. Bytecode interpreter
• EE. Garbage Collector
