The WebShipAnywhere company currently has a manual Order-to-Ship process. The company is implementing Service-Oriented Integration architecture and, as part of that initiative, they are automating the Order-to-Ship process.
Whenever an order ships, the Warehouse Management System (WMS) is manually updated to reflect that the order has been shipped. If the Inventory for any product that was part of the order drops below a threshold value, the WMS alerts the user via a pop-up screen indicating that the product inventory is low. When this happens, the user logs in to the Purchasing System (PS) and enters the need to order more of the product. Both the WMS and PS are thick-client, two-tier applications that use an Oracle database. As part of automating the Order-to-Ship process, the company would like to remove this manual step.
What integration pattern(s) should be used to automate this manual step?

• A.Because both the WMS and the PS use Oracle database, the WMS should be modified to use a trigger to update the PS database whenever a low inventory is detected.
• B.The polling integration pattern should be used to detect that the inventory for a product is low in the VMS. If a product inventory is low, a "low-inventory" event should be created and published to a topic queue following the publish-and-subscribe pattern. An event handler registered for the "low inventory" event then receives the event and updates the PS.
• C.It is not possible to integrate thick-client, two-tier applications (such as VMS and PS) by using a SOI architecture. Only applications with service interfaces can be included in an SOI architecture
• D.The polling integration pattern should be used to detect that the inventory for a product is low in the WMS. If a product inventory is low, the polling component uses a reliable-one-way message to call an SOA Service that updates the PS.
• E.The WMS should be modified to create a "low-inventory" event and publish the event to a topic queue following the publish-and-subscribe pattern. An event handler registered for the "lowinventory" event then receives the event and updates the PS.

Which statements are true with regard to authorization checks being done in the Mediation Layer?

• A.Performing authorization checks in the Mediation Layer requires that all secured SOA Services be accessed via the same protocol.
• B.Performing authorization checks in the Mediation Layer eliminates the need for role-based authentication.
• C.Performing authorization checksin the Mediation Layer provides a centralized approach to securing SOA Services.
• D.Performing authorization checks in the Mediation Layer requires that all secured SOA Services be accessed only via the Mediation Layer.
• E.Performing authorization checks in the Mediation Layer requires that user authentication be based on username and password.

Which of the following statements are true about perimeter security?

• A.Though it is often associated with network security, it also applies to physical security measures as fences and locked doors.
• B.It is most effective when there is only one perimeter. For example, when inner perimetersare established, they reduce the effectiveness of outer perimeters.
• C.Connections should not be permitted to span more than one perimeter or firewall.
• D.Perimeter security can be a component of a defense-in-depth strategy.
• E.Perimeter security is most effective for protection against insider threats.
• F.The Demilitarized Zone (DMZ) is the most protected zone of the network, which should be reserved for only the most sensitive data.

Which statement best describes how Service-Oriented Integration (SOI) differs from traditional Enterprise Application Integration (EAI)?

• A.EAI integrates applications whereas SOA integrates SOA Services.
• B.SOI uses SOA Services that are separate and distinct from the applications being integrated
• C.SOI uses a point to-point integration approach based on the Web Services Industry standards.
• D.SOI is Just like EAI except that a service bus is used Instead of a hub or message bus.
• E.SOI is different than hub-based EAI, but is the some as EAI using a message bus.
