Marcie, Lauren, and Nancy are part of a project team to create an Inventory Application for ABC industries. The team members need to perform the following activities daily:

• Nancy: Manage workspaces, and approve storage requests
• Lauren: Modify database objects, view session state and view application reports. What privileges would you assign to these three users?

  • C. Marcie: Application Express Administrator, Nancy: Workspace Administrator, Lauren: Developer
  • D. Marcie: Workspace Administrator, Nancy: Application Express Administrator, Lauren: Developer
  • E. Marcie: Workspace Administrator, Nancy: Workspace Administrator, Lauren: Developer

Answer: C

Explanation:

Marcie needs to modify applications and manage users groups so she needs at least the Developer privileges and WorkSpace administrator (not A, not B, not D, not E).
Nancy needs to handle workspaces and approve storage requests so she needs at least the WorkSpace Administrator privileges or Application Express Administrator (not A, not B).
Lauren as a Developer would be fine.
Note: When setting up Application Express users at a large organization, you assign roles and privileges to specific users. The roles within Application Express include the following:
* Workspace administrators are users who perform administrator tasks specific to a workspace such as managing user accounts, monitoring workspace activity, and viewing log files. For this guide, you will be acting as the workspace administrator when setting up the development environment.
* Developers are users who create and edit applications. Developers can have their own workspace or share a workspace.
* End users have no development privileges. You define end users so that they can access applications that do
not use an external authentication scheme.
* Oracle Application Express administrators are superusers that manage an entire hosted instance using the Application Express Administration Services application.

  • D. An authentication scheme helps a user to reestablish their session when they log back into an application allowing them to bookmark the application.
  • E. An authentication scheme can only be applied to one applicatio

Answer: AC

Explanation:

A: Authentication establishes the identity of each user who accesses your application. Authentication is the process of establishing each user's identify before they can access your application. Authentication may require a user identify a user name and password or could involve the use of digital certificates or a secure key.
C: When running custom authentication, Oracle Application Express attempts to prevent two improper situations:
* Intentional attempts by a user to access session state belonging to someone else. However, users can still type in an arbitrary application session ID into the URL.
* Inadvertent access to a stale session state (probably belonging to the same user from an earlier time). This
would commonly result from using bookmarks to application pages.
