MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of...	data virtualization.	incorrect	data propagation.	correct	data federation.	incorrect	data consolidation.	incorrect	
MC	Which statement is NOT CORRECT?	Process execution languages such as WS-BPEL aim at managing only the data flow.	correct	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	The data flow perspective of a business process focusses on the inputs of the tasks (e.g., the interest rate offered depends on the credit score). 	incorrect	Ideally, data integration should include both processes and data.	incorrect	
MC	Which statement is NOT CORRECT?	Analytics for tactic/strategic decision making increasingly uses real-time operational data combined with the aggregated and historical data found in more traditional data warehouses.	incorrect	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	correct	The operational usage of business intelligence aims for a low (or even zero) latency so interesting events or trends in the data can be immediately detected and accompanied with the appropriate response.	incorrect

MC	Which statement is NOT CORRECT?	An important disadvantage of the consolidation approach is that it does not cater for historical data.	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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	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 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

MC	Which statement is NOT 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	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	A key element in MDM is a centrally governed data model and metadata repository.	incorrect	The focus of MDM is on unifying company-wide reference data types such as customers and products.	incorrect
