Exam 1z0-134 topic 1 question 51 discussion

Actual exam question from Oracle's 1z0-134

Question #: 51
Topic #: 1

Review the diagram below. It depicts the following:
✑ A WebLogic domain that consists of two WebLogic clusters that are each included in a Coherence cluster
✑ The Coherence cluster includes a configuration for Coherence*Web HTTP session storage
✑ An application deployed on cluster 1 that is configured to use Coherence*Web
✑ A client is using a web browser to interact with the application on cluster 1 (via a proxy)
✑ The clients HTTP session is stored by Coherence*Web on the Server in the upper right-hand corner
The server where the clients HTTP session is stored crashes

Assuming the next request for an HTTP session attribute is a new attribute that is not stored in a near-cache, the clients session attribute is fetched from the remaining storage-enabled server in cluster 2.
Why is the session attribute retrieved from this other servers cache? (Choose the best answer.)

A. Coherence*Web stores sessions in a distributed cache on the back end and the request fails over to the new location after partition re-balancing takes place.
B. Coherence*Web stores sessions in a replicated cache on the back end and the request fails over to the new location automatically.
C. Coherence*Web stores sessions in a shared disk cache on the back end and Coherence*Web automatically load balances requests.
D. Coherence*Web stores sessions in a cache that is backed by a database cache loader. The data is fetched from the database and placed into the cache on the new server.
