最新的 OPN Certified Specialist 1z0-468 免費考試真題：

問題 #1

Assume that network latency between two data centers is 5 milliseconds with minimal packet loss.
Identify two problems with running one Coherence cluster that spans these two data centers (Choose two.)

A. Network latency will lead to cluster instability.
B. Outage in the WAN link can cause split brain.
C. Total loss of power in one data center can lead to split brain.
D. Access and writes to data takes longer to complete.

問題 #2

Which Java command would list all the running Java applications on a system?

A. jplist -m
B. jproc -m
C. jps -m
D. jpsm -m
E. jlist -m

問題 #3

Identify three situations where Coherence is used (Choose three.)

A. to offload shared services or databases on repeated reads
B. to accelerate complex RDBMS joins by storing data in memory
C. to perform map-reduce aggregations of unstructured data
D. to reduce database load by batching and coalescing writes
E. to scale the amount of data accessed on the application or middleware tier

問題 #4

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

問題 #5

You have developed and tested your Coherence application on a single physical machine by using the following operational configuration:

What two configuration changes must be made to run your application on multiple physical machines using multicast? (Choose two.)

A. Lower the logging severity level to 3.
B. Specify a list of well-known addresses.
C. Increase the multicast listener time-to-live value.
D. Change the unicast listener address to a non-loopback address.
