MC	The federation pattern typically follows...	a pull approach	correct	a push approach	incorrect	
MC	The choreography pattern to manage sequence and data dependencies is a...	centralized approach.	incorrect	decentralized approach.	correct	
MC	Which statement is NOT CORRECT?	The focus of MDM is on unifying company-wide reference data types such as customers and products.	incorrect	A key element in MDM is a centrally governed data model and metadata repository.	incorrect	Master Data Management (MDM) compromises a series of processes, policies, standards, and tools to help organizations to define and provide multiple points of reference for all data that is "mastered". 	correct	Setting up an MDM initiative involves a large number of steps and tools, including data source identification, mapping out the systems architecture, constructing data transformation, cleansing and normalization rules, providing data storage capabilities, monitoring and governance facilities, and so on. 	incorrect	
MC	Process execution languages such as WS-BPEL aim at managing...	only the control flow.	incorrect	only the data flow.	incorrect	both the control and data flow.	correct	
MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Enterprise Information Integration (EII) is an example of...	data propagation.	incorrect	data replication.	incorrect	data consolidation.	incorrect	data integration.	correct	
MC	Which statement is NOT CORRECT?	Contrary to a federated database as offered by basic EII, data virtualization does not impose a single data model on top of the heterogeneous data sources.	incorrect	Besides the traditional set-up with ETL and a data warehouse, data lakes can also be considered an implementation of the consolidation pattern. 	incorrect	The choreography pattern to manage sequence and data dependencies is a centralized approach.	correct	The federation pattern typically follows a pull approach.	incorrect	
MC	Which statement is NOT CORRECT?	Contrary to a federated database as offered by basic EII, data virtualization does not impose a single data model on top of the heterogeneous data sources.	incorrect	In many real-life contexts, a data integration exercise is an ongoing initiative within an organization, and will often combine a variety of integration strategies and approaches.	incorrect	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	correct

MC	Which statement is NOT CORRECT?	An ETL process typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.	incorrect	An important disadvantage of the consolidation approach is that it does not cater for historical data.	correct	The essence of data consolidation as a data integration pattern is to capture the data from multiple, heterogeneous source systems and integrate it into a single persistent store (e.g., a data warehouse or data mart). 	incorrect	Besides the traditional set-up with ETL and a data warehouse, data lakes can also be considered an implementation of the consolidation pattern. 	incorrect
