Discuss Dama CDMP-RMD Exam Topic 5 Question 47

Which of the following is NOT ,1 characteristic of n deterministic matching algorithm?

AIs better suited when there is no great consequence to an error in matching

BIs not highly dependent on the quality of the data being matched

CHas a discrete all or nothing outcome

DMatches exact character to character of one or more fields

EAll identifiers being matched have equal weight

Suggested Answer: B

Deterministic matching algorithms rely on exact matches between data fields to determine if records are the same. These algorithms require high-quality data because any discrepancy, such as typographical errors or variations in data entry, can prevent a match.

Characteristics of deterministic matching:

It has a discrete all or nothing outcome (C).

It matches exact character to character of one or more fields (D).

All identifiers being matched have equal weight (E).

Since deterministic matching is highly dependent on the quality of the data being matched, option B is incorrect.

I agree, option C is spot on!

A deterministic algorithm definitely has a discrete outcome.

I thought all identifiers having equal weight was a feature of deterministic matching, so E might be the one that doesn't fit.

I'm not entirely sure, but I feel like A could be a characteristic of deterministic algorithms since they can handle errors better in some cases.

I remember a practice question where we discussed how deterministic matching gives a clear yes or no outcome, so maybe C is not the right answer here.

I think option B sounds a bit off because deterministic algorithms usually rely heavily on data quality, right?
