Critical Fields are used to identify fields that must agree in order for records to be linked. ✘ Critical Fields do not have to match exactly. ✘ Only critical fields of a record are used to calculate the composite weights of the record. ✘ Critical Fields are fields with missing values. ✔

Field name, data type, and position in record. ✘ Class, token, and standard form. ✘ Pattern of tokens, actions to execute, and the logic. ✘ Token, standard form, class, and override rules. ✔

transforming the data from one data type to another. ✘ discovering the actual values of missing data. ✘ verifying the reliability of the data in the fields to be used as matching criteria. ✘ identifying all the data sources for data consolidation. ✔

Setting up project properties. ✘ Scheduling jobs to execute. ✘ Compiling all the jobs at once. ✘ Exporting log messages for a job. ✔

Single domain fields. ✘ Multiple domain fields. ✘ Both single domain and multiple domain fields. ✘ None of the above. ✔

Use only one Match Pass. ✘ Set critical values for important fields. ✘ Add additional passes. ✘ Adjust weights using weight overrides. ✔

group records together that are considered duplicates. ✘ discover trends and anomalies. ✘ identify invalid and default values. ✘ examine single domain and free-form text fields. ✔

The severity of false positives and false negatives. ✘ The significance of discriminating value and frequency. ✘ The degree of importance of a particular data field. ✘ The confidence of a match. ✔
