Oracle Oracle Certifications 1Z0-468 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.

• Question 48:

  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?

  A. a replicated cache, so that applications can always access data locally

  B. there is too much data for Coherence to be effective in this scenario

  C. a distributed cache with sticky sessions and near caching

  D. a small replicated cache for frequent users and database read-through

  Correct Answer: C
