Which would you configure so that an Oracle Enterprise manager user has the ability to perform
jobs without having to know specific credential information?

A.
A named credential

B.
A pseudo account

C.
A user job credential

D.
A named job

Explanation:
A named credential is a users’ authentication information on a system. A named
credential can be a user name/password, a public key-private key pair, or an X509v3 certificate.
An Enterprise Manager administrator can store these credentials as named entities in Enterprise

Manager to use when performing operations like running jobs, patching, and other system
management tasks. For example, you can store the user name and password that you want to use
for patching as MyPatchingCreds. You can then later submit a patching job that uses
MyPatchingCreds to patch the production databases.
Named Credentials can be created for the credential types in Enterprise Manager 12c. The most
commonly used credential types for host and database target types are described in the following
sections.
