A bank is launching a new mobile device notification channel to their online banking system that
will allow customers to receive SMS/text messages and email notifications regularly about their
current balance and recent transactions over a certain amount. The bank has 300 million
customers in thirty countries, covering time zones from GMT-8 to GMT+8. The messages sent
are informational only and are not legally binding. The mid and back office systems are built using
both relational databases and legacy mainframe-based systems. What is the most appropriate
method for the mid and back office systems to integrate with the mobile device notification
channel?
A.
guaranteed messaging using message-driven beans (MDBs) consuming messages from a
JMS queue populated by the systems of record
B.
unguaranteed messaging using message-driven beans (MDBs) consuming messages from a
JMS topic populated by the systems of record
C.
unguaranteed messaging using message-driven beans (MDBs) consuming messages from a
JMS queue populated by the systems of record
D.
stateless session beans retrieving records of interest directly from the mid and back office
systems using a combination of JDBC and green screen scraping
