A. Agreement weight

B. Both missing weight

C. Data missing weight

D. Disagreement weight

E. Reference missing weight

You added a new field to matching fields of an existing match specification and provisioned all match specification components. Then you ran the job but it failed immediately. The input data size is 2G bytes and the job worked without any issues before you modified.

What is most likely the cause of the problem?

A. Lack of physical memory.

B. Lack of scratch disk space.

C. The job needs to be re-compiled.

D. The frequency file needs to be re-generated.

A. Use normal lookup in the lookup stage.

B. The Lookup stage should be replaced with Join stage.

C. You can select reference data from the database using user defined SQL.

D. You need to add two more Lookup stages to select necessary reference data.

Which statement is true regarding Quality Stage data survivorship?

A. Survivorship is used to create groups of duplicate records.

B. The Survive stage is used to mark records as possible duplicates.

C. The Survive stage is used after matched record groups have been identified.

D. The Survive stage can be used to correct and identify unhandled data from the Standardize stage.
