Demo Questions

Question 1
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

Question 2
What is the difference between Entry Processors and Aggregators?

  • A: Entry Processors require a key or a set of keys, whereas Aggregators require filters.
  • B: Entry Processors can skip the network by executing against near caches directly, whereas Aggregators must execute on storage members.
  • C: Entry Processors are better suited to Map-Reduce operations than Aggregators.
  • D: Aggregators are optimized for read-only access, whereas Entry Processors can modify cacheentries.

Question 3
Which statement about JRockit Discovery Protocol (JDP) is true?

  • A: JDP enables network auto discovery of JVMs.
  • B: JDP is a subset of HTTP.
  • C: JDP can be used by application to exchange serialized data between JVMs.
  • D: JDP was initially introduced in the HotSpot VM 1.5.

Question 4
How would you create an SLA based on the “JVM Runtime Up” metric for a specific WLS server?

  • A: Deploy JVM Diagnostics and set a threshold on the JVMD agent up time.
  • B: Create a Service target that uses the WLS Domain as its system, and the JVM Runtime as itsperformance metric. Configure SLA by using that metric.
  • C: Define a threshold on the metric on the All Metrics page, and define a rule to create an Event for that incident. Define an SLA on the count of Incidents.
  • D: You cannot create an SLA on JVM-related metrics.

Question 5
Your application will store data in two partitioned caches, each configured for one backup. You have calculated the total amount of data to be 10 GB for the first cache, and 3 GB for the second cache. You plan to run 10 cache servers in total.
What is the minimum recommended JVM heap size for each cache server?

  • A: 512 GB
  • B: 1 GB
  • C: 2 GB
  • D: 4 GB

Question 6
Which type of appliance would you use to package custom applications into an appliance?

  • A: WebLogic Server appliance
  • B: external appliance
  • C: generic appliance
  • D: database appliance
  • E: Oracle Tuxedo appliance

Question 7
Which statement describes the difference between the Runtime Analyzer and JRockit Flight Recorder?

  • A: Only Runtime Analyzer allows detailed heap analysis.
  • B: Only Flight Recorder allows “back-in-time” analysis.
  • C: Thread deadlock analysis is not possible in Flight Recorder.
  • D: Flight Recorder cannot be run in an "always-on" mode.
  • E: Flight Recorder causes significantly higher processor overhead than Runtime Analyzer.

Question 8
When an object placed into a cache implements the Java Runnable interface, Coherence will.

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

Question 9
What is the primary purpose of the Middleware Diagnostics Advisor (MDA) included in WLS Management Pack EE?

  • A: to automate the SQL tuning process by comprehensively exploring all the possible ways of tuning a SQL statement
  • B: to facilitate proactive performance and availability management by auto-finding problems and suggesting solutions
  • C: to find configuration problems by comparing WLS configuration to a Gold Image configuration
  • D: to provide comprehensive advice on how to optimize schema design in order to maximize application performance
  • E: to analyze the EM configuration and suggest configuration changes that will extend the stability of EM

Question 10
Which change cannot be made in an assembly at deployment time?

  • A: setting the appliance’s memory and CPU requirements
  • B: changing the listening port of the product
  • C: not deploying an appliance by setting its target count to zero
  • D: not deploying an appliance by removing it from the assembly
