Oracle 1Z0-468 Online Questions & Answers

• Question 41:

  Your customer is a financial services company that uses a large compute grid (not Coherence) to do risk calculations. Objects representing risk scenarios are cached in Coherence. When these objects are updated, they are sent to the compute grid to recalculate risk via a continuous query cache. Assume that there are 100 compute servers in one data center and 100 GB of cached data. The customer is not worried about potential cluster instability, given their network design.

  Which solution supports the customer's requirements? Keep in mind licensing costs and features by edition.

  A. Coherence Standard Edition. Nothing special is needed and Standard Edition is the low- cost option.
  B. Coherence Enterprise Edition, with the compute grid clients being storage-disabled cluster members.
  C. Coherence Grid Edition, with the compute grid clients being storage-disabled Coherence cluster members.
  D. Coherence Enterprise Edition, with the compute grid running against a set of Coherence*Extend proxies and continuous query cache on Coherence*Extend clients.
  A. Coherence Standard Edition. Nothing special is needed and Standard Edition is the low- cost option.

• Question 42:

  Which component is optimized for the JRockit VM?

  A. swing-based desktop applications
  B. browser-based applets
  C. embedded devices
  D. server-side applications
  E. mobile phones
  D. server-side applications

• Question 43:

  You are doing capacity planning for a Coherence application with one distributed cache (dcache), and one replicated cache (rcache). You have one index on dcache, and dcache has backup_count=1. Your requirement is that you must be able to tolerate one machine failure with no loss of data. You have three machines, each with 4 JVMs of 8 GB.

  What three factors do you take into consideration in case of machine failure? (Choose three.)

  A. Each cache server will be responsible for more primary and backup data from dcache.
  B. The size of index data in each cache server is likely to grow.
  C. The size of rcache on each node will grow.
  D. Updates to rcache will result in more network traffic per machine.
  E. Updates to dcache will result in more network traffic per machine.
  A. Each cache server will be responsible for more primary and backup data from dcache.
  B. The size of index data in each cache server is likely to grow.
  E. Updates to dcache will result in more network traffic per machine.

• Question 44:

  Which system property is used to customize a Coherence deployment configuration for different environments?

  A. tangosol.coherence.cacheconfig
  B. tangosol.coherence.site
  C. tangosol.coherence.management
  D. tangosol.coherence.override
  A. tangosol.coherence.cacheconfig

• Question 45:

  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.
  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.

• Question 46:

  Which three plug-ins are pre-installed with EM 12c?

  A. Oracle Fusion Middleware
  B. Oracle Cloud Application
  C. Oracle Database
  D. Oracle MOS (My Oracle Support)
  E. Exalogic Elastic Cloud Infrastructure
  A. Oracle Fusion Middleware
  D. Oracle MOS (My Oracle Support)
  E. Exalogic Elastic Cloud Infrastructure

• Question 47:

  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
  A. setting the appliance's memory and CPU requirements

• Question 48:

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

  A. Enterprise Manager agent on every host, querying JMX data from nodes running on that host
  B. one central Enterprise Manager agent, querying JMX data from each node in the cluster
  C. JVMD agent collecting data trough sampling of the JVM for each node
  D. 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
  E. one central Enterprise Manager agent querying JMX data from a single management node
  D. 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
