MC	Which statement is CORRECT?	It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. 	incorrect	The prevalent approach for indexing full text documents is an inverted index.	correct	Enterprise search technologies are strongly related to standard web search products and providers (e.g., Google), but aim to offer a series of tools which can be deployed and used externally such that an organization can expose itself to the outside world.	incorrect	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect	
MC	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of...	data propagation.	correct	data virtualization.	incorrect	data consolidation.	incorrect	data federation.	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?	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	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	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
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	Ideally, data integration should include...	both processes and data.	correct	only processes.	incorrect	only data.	incorrect	
MC	Which statement is CORRECT?	Process execution languages such as WS-BPEL aim at managing both the control and data flow.	correct	The federation pattern typically follows a push approach.	incorrect	Enterprise Information Integration (EII) is an example of data propagation.	incorrect	Process execution languages such as WS-BPEL aim at managing only the control flow.	incorrect	
MC	Which statement is NOT CORRECT?	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	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	
MC	Which statement is CORRECT?	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	incorrect	The choreography pattern to manage sequence and data dependencies is a centralized approach.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	incorrect	The choreography pattern to manage sequence and data dependencies is a decentralized approach.	correct
