3 Logical Data Maps | ETL Testing Mcqs
A. These are used to identify which fields from which sources are going to with destinations. It allows the ETL developer to identify if there is a need to do a data type change or aggregation prior to beginning coding of an ETL process.
B. These can be used to flag an entire file-set that is ready for processing by the ETL process. It contains no meaningful data bu the fact it exists is the key to the process.
C. Data is pulled from multiple sources to be merged into one or more destinations.
D. It is used to massage data in transit between the source and destination.
Ans: A
4 Data access methods. | ETL Testing Mcqs
A. Pull Method
B. Push and Pull
C. Load in Parallel
D. Union all
Ans: B
5 OLTP | ETL Testing Mcqs
A. Process to move data from a source to destination.
B. Transactional database that is typically attached to an application. This source provides the benefit of known data types and standardized access methods. This system enforces data integrity.
C. All data in flat file is in this format.
D. This control can be used to add columns to the stream or make modifications to data within the stream. Should be used for simple modifications.
Ans: B
6 COBOL | ETL Testing Mcqs
A. Process to move data from a source to destination.
B. The easiest to consume from the ETL standpoint.
C. Two methods to ensure data integrity.
D. Many routines of the Mainframe system are written in this.
Ans: D
7 What ETL Stands for | ETL Testing Mcqs
A. Data inspection
B. Transformation
C. Extract, Transform, Load
D. Data Flow
Ans: C
8 The source system initiates the data transfer for the ETL process. This method is uncommon in practice, as each system would have to move the data to the ETL process individually. | ETL Testing Mcqs
A. Custom
B. Automation
C. Pull Method
D. Push Method
Ans: D
9 Sentinel Files | ETL Testing Mcqs
A. These are used to identify which fields from which sources are going to with destinations. It allows the ETL developer to identify if there is a need to do a data type change or aggregation prior to beginning coding of an ETL process.
B. These can be used to flag an entire file-set that is ready for processing by the ETL process. It contains no meaningful data bu the fact it exists is the key to the process.
C. ETL can be used to automate the movement of data between two locations. This standardizes the process so that the load is done the same way every run.
D. This is used to create multiple streams within a data flow from a single stream. All records in the stream are sent down all paths. Typically uses a merge-join to recombine the streams later in the data flow.
Ans: B
10 Checkpoints | ETL Testing Mcqs
A. Similar to "break up processes", checkpoints provide markers for what data has been processed in case an error occurs during the ETL process.
B. Similar to XML's structured text file.
C. Many routines of the Mainframe system are written in this.
D. It is used to import text files for ETL processing.
Ans: A
11 Mainframe systems use this. This requires a conversion to the more common ASCII format. | ETL Testing Mcqs
A. ETL
B. XML
C. Sort
D. EBCDIC
Ans: D
12 Ultimate flexibility, unit testing is available, usually poor documentation. | ETL Testing Mcqs
A. ETL
B. Custom
C. OLTP
D. Sort
Ans: B
13 Conditional Split | ETL Testing Mcqs
A. Many routines of the Mainframe system are written in this.
B. Data is pulled from multiple sources to be merged into one or more destinations.
C. It allows multiple streams to be created from a single stream. Only rows that match the criteria for a given path are sent down that path.
D. This is used to create multiple streams within a data flow from a single stream. All records in the stream are sent down all paths. Typically uses a merge-join to recombine the streams later in the data flow.
Ans: C
14 Flat files | ETL Testing Mcqs
A. The easiest to consume from the ETL standpoint.
B. Three components of data flow.
C. Three common usages of ETL.
D. Two methods to ensure data integrity.
Ans: A
15 This is used to create multiple streams within a data flow from a single stream. All records in the stream are sent down all paths. Typically uses a merge-join to recombine the streams later in the data flow. | ETL Testing Mcqs
A. OLTP
B. Mainframe
C. EBCDIC
D. Multicast
Ans: D
16 There are little to no benefits to the ETL developer when accessing these types of systems and many detriments. The ability to access these systems is very limited and typically FTP of text files is used to facilitate access. | ETL Testing Mcqs

B. Union all
C. File Name
D. Multicast
Ans: A
