MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Which of the following statements on data integration is not correct?	If performance is the only criterion, replication can be used.	incorrect	Event data should be treated with care. It is safer to pass this via the data layer only.	correct	When providing data services based on a federation architecture, real-time, comprehensive data is often used. 	incorrect	Data lineage is difficult to assess when data is copied and distributed.	incorrect	
MC	Which of the following statements on data and process integration is not correct?	Data integration deals with both processes and data sources. 	correct	Zero or low latency is desired in applications such as BAM, monitoring KPIs or business process monitoring.	incorrect	For a long time, operational applications and BI and analytics were separated from one another in their data storage and processing landscape. 	incorrect	Originally, departments were often supported by their own data silo. 	incorrect	
MC	Which statement is NOT 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	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	Which of the following statements on searching unstructured data is not correct?	SQL is well suited for both structured and unstructured search. 	correct	Using inverted indexes is the prevalent approach in searching unstructured data. 	incorrect	A web search engine often uses a ranking module to sort the result set. 	incorrect	Often extensions such as thesaurus, fuzzy logic and text mining techniques are provided. 	incorrect	
MC	Process execution languages such as WS-BPEL aim at managing...	only the control flow.	incorrect	both the control and data flow.	correct	only the data flow.	incorrect	
MC	Which statement is NOT CORRECT?	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data consolidation.	correct	The prevalent approach for indexing full text documents is an inverted index.	incorrect	A key element in MDM is a centrally governed data model and metadata repository.	incorrect	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	
MC	Which statement is NOT CORRECT?	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 extensively uses data consolidation techniques such as ETL.	correct	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	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	
MC	The choreography pattern to manage sequence and data dependencies is a...	decentralized approach.	correct	centralized approach.	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	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
