Which statement is a reason to use external eXtreme Scale data cache with IBM Integration Bus?
A. The data cache must be Highly-Available within a data center.
B. The data cache must be shared across multiple Integration Nodes.
C. The data cache must be shared across multiple Integration Servers.
D. Data replication across data centers is required for Continuous Availability.
Correct Answer: C
Explanation/Reference:
Explanation:
Choose an external grid if you have any of the following requirements:
You have an architectural preference for the cached data not to be placed in the integration servers themselves.
You want to separate the availability of the cache from the availability of the integration servers.
You need an enterprise cache, with multiple applications (other than IBM Integration Bus) that are accessing the data.
You have (or want) sophisticated, or custom, tools to manage the cache.
The cache needs to span multiple data centers for disaster recovery.
You need to configure the grid for specific capabilities that are not supported by the embedded global cache.
