E.

Explanation:
XA Affinity and Failover
When accessed within a global transaction, the member data source from which the
JDBC connection was obtained is pinned to the global transaction for the life of
the transaction. This ensures that all database operations performed onconnections obtained from the Multi Data Source, for a particular transaction, all
execute on the same RAC instance. XA affinity results in improved performance
and is even a requirement for older versions of RAC, such as prior to 11g.
The XA failover is also supported by the Multi Data Source and transaction
manager implementations. If a pinned RAC instance suffers a failure, then a global
transaction can complete utilizing a different RAC instance using a connection
obtained one of the other member data sources.

Answer B. Here you can find full description: http://my-java-planet.blogspot.com/2014/04/which-weblogic-optimization-allows-one.html
This answer seems wrong. Refer below link
http://docs.oracle.com/cd/E13222_01/wls/docs92/jta/llr.html
WebLogic Server 9.0 includes support for the Logging Last Resource (LLR) transaction optimization through JDBC data sources. LLR is a performance enhancement option that enables one non-XA resource to participate in a global transaction with the same ACID guarantee as XA. LLR is a refinement of the “Last Agent Optimization.” It differs from Last Agent Optimization in that it is transactionally safe. The LLR resource uses a local transaction for its transaction work. The WebLogic Server transaction manager prepares all other resources in the transaction and then determines the commit decision for the global transaction based on the outcome of the LLR resource’s local transaction.
B is the correct

Very good blog! Do you have any tips for aspiring writers? I’m planning to start my own website soon but I’m a little lost on everything. Would you recommend starting with a free platform like WordPress or go for a paid option? There are so many choices out there that I’m totally confused .. Any ideas? Thanks a lot!

Logging Last Resource (LLR) is a performance enhancement option that
enables one non-XA resource to participate in a distributed transaction. So options should be ‘B’
