Question 1
[Performance Optimization] Data pages offer a "Do not reload when" option for optimizing data retrieval. Which two of the following scenarios make appropriate use of this feature? (Choose Two)
A.
A data page tracks real-time seat availability for a theater. Because seat bookings stop once the show starts, set it to not reload after the show begins until it ends.
B.
A data page maintains reservation details for a hotel. To optimize performance, set it to not reload after check-in time ends, because no new reservations are taken overnight unless you have approval from the manager of the hotel.
C.
A data page pulls live traffic updates for a delivery service's routing system. Because traffic patterns stabilize late at night, set it to not reload from late evening until early morning.
D.
A data page holds the daily menu for a cafeteria that doesn't change the menu once the kitchen opens. To avoid unnecessary updates, set it to not reload after the kitchen begins its operations until the next day.

Question 2
[Data Modeling] In a flight schedule management application, the initiation of a scheduled flight case triggers both pre-flight check and flight catering service processes. These processes require access to flight information, such as flight number, cabin class, number of seats, departure date and time, while also maintaining process-specific data elements. Which one of the following options best describes the optimal data model for meeting this requirement?
A.
Set Schedule Flight as the parent case type, with the triggered processes as child case types. Store flight data within the Schedule Flight case. This data will then bepropagated to the child cases upon their creation.
B.
Set Schedule Flight as the parent case type, with the triggered processes as child case types. Place flight data in the travel management enterprise layer and create data classes specific to each child case type, inheriting directly from the travel management enterprise layer.
C.
Set Schedule Flight as the parent case type, with the triggered processes as child case types. Place flight data within the Schedule Flight class and develop data classes specific to each child case type.
D.
Set Schedule Flight as the parent case type, with the triggered processes as child case types. Place flight data within the work pool class, allowing all three case types to inherit properties from the work pool class.

Question 9
[Work Delegation and Asynchronous Processing] The ABC trip planner company offers a variety of services, for example, hotel bookings, flight bookings, and train bookings, all on a single platform. All the services offered havetheir invoice processing managed by a dedicated team of accounting specialists from the XYZ financial accounting organization. Every booking made by a customer creates a "Booking" case, which manages the booking of the required service. An "Invoice" case is also created for the verification and validation of all payments to the various stakeholders involved. For security reasons, the Invoice case contains limited information and cannot be a child case of Booking. Both are siblings that update each other. Which one of the following is the best possible solution to implement this requirement?
A.
Have a data object that connects both the sibling cases. Use a Job Scheduler that runs every one minute to query records from the data object and update the sibling case as required. Use system context to gain access to the sibling case.
B.
Have a data object that connects both the sibling cases. Use a Job Scheduler that runs every one minute to query records from the data object and update the sibling case as required.
C.
Have a data object that connects both the sibling cases. Use a queue processor (Dedicated/Standard) to process the record for status updates. Update the security context while queuing with the appropriate access group to gain access to the sibling case.
D.
Have a data object that connects both the sibling cases. Use a queue processor (Dedicated/Standard) to process the record for status updates. Use the current operator access group context while queuing to update the case.

Question 11
[Integration] U+ Bank has a customer service application that processes customer complaints. Now, after three years in production, the operations manager needs historical reports on resolved cases. The reports should be sent in near real-time. The data warehouse has exposed a REST API to receive the data, and the reports are then generated from the data warehouse. Which two of the following options could you use to create an ideal design solution for posting the data to the data warehouse? (Choose Two)
A.
Read data with data flows, which source data by using a dataset and then output the data to a utility that synchronously posts the data to the data warehouse. For in-flight cases, on resolution of the case, configure the system to post the data to the data warehouse over REST.
B.
Prepare an extract rule and extract the data of already-resolved cases, and then load it into the data warehouse for reporting. For in-flight cases, on resolution of a case, configure the system to post the data to the data warehouse over REST.
C.
Read data with data flows, which source data by using a dataset and then output the data to a utility that posts the data to the queue processor, which then posts the data tothe data warehouse over REST. For in-flight cases, on resolution of a case, reuse a queue processor that you created.
D.
Run a one-time utility that browses all the resolved-cases data, and then asynchronously posts the data to the data warehouse. For in-flight cases, on resolution of a case, configure the system to synchronously post the data to the data warehouse over REST.
