1Z0-478 Latest Exam Braindumps

Question 9: In your solution, a web service client needs to invoke a series of three web services in support
of a single transaction. The third web service needs the identity of the original web service client.
Which statement describes how the identity is made available by Oracle Web Services Manager
(OWSM)?
A. The transaction manager accesses an internal table that maintains credentials used to invoke
each individual web service in the chain.
B. Each web service in the chain does its own authentication so the third web service handles its
own identity checking.
C. OWSM sets the user in the Java Authentication and Authorization (JAAS) Subject when the first
web service successfully authenticates, and the Java Subject is used by subsequent web services to
access the identity.
D. OWSM stores a SAML token from the first web service invocation in a database table, and that
table is accessed by subsequent web services in the chain to retrieve identity.
Correct Answer: D
Explanation:
Oracle Web Services Manager is a component of the Oracle Enterprise Manager Fusion Middleware
Control, a run-time framework that provides centralized management and governance of Oracle
SOA Suite environments and applications. You create and configureOracle Web Services Manager
policies in Oracle Enterprise Manager, and those policies are persisted in a policy store (a database
is recommended). Oracle Web Services Manager lets you define policies against an LDAP directory
and generate standard security tokens (such as SAML tokens) to propagate identities across multiple
Web services used in a single transaction.
