[All 1Z0-134 Questions]

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 client's HTTP session is stored by Coherence*Web on the server in the upper right-hand corner

The server where the client's 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 client's session attribute is fetched from the remaining storage-enabled server in cluster 2.

Why is the session attribute retrieved from this other server's cache? (Choose the best answer.)

ACoherence*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.

BCoherence*Web stores sessions in a replicated cache on the back end and the request fails over to the new location automatically.

CCoherence*Web stores sessions in a shared disk cache on the back end and Coherence*Web automatically load balances requests.

DCoherence*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.

Suggested Answer: E

Rolling upgrade applies only to upgrades within a major product version. For example, you can upgrade from 10.0 to 10.3.1, but cannot upgrade from 9.0 to 10.0.

D sounds like the most comprehensive answer, mentioning the database cache loader. But I'm not familiar with how Coherence*Web integrates with databases.

B seems plausible, but I'm not sure if Coherence*Web uses a replicated cache by default. Gotta read up on the cache topologies.

But doesn't Coherence*Web use distributed cache for session storage?

I think the answer is A. Coherence*Web uses a distributed cache, so the session should fail over to another server after the original one crashes.

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.
