When is it possible for IRE to reclassify a CI from one class to another?
- When the two classes have identical identification rules
- When the two classes share the same parent class
- When neither of the two classes has identification rules
- When the two classes have the same number of attributes
Show the answer and explanation
Answer: A
Why this is correct
CI reclassification is possible only between two classes that have identical identification rules. If the rules differed, the basis for uniquely identifying the CI would change.
Why the other options are wrong
"When the two classes share the same parent class" … Sharing a parent is not the condition. Reclassification requires identical identification rules.
"When neither of the two classes has identification rules" … The condition is identical identification rules. A class without rules gives IRE no way to identify the CI.
"When the two classes have the same number of attributes" … Reclassification depends on the identification rules of the two classes, which must be identical. Attribute count plays no part in that condition.
Key point
A class can be upgraded, downgraded, or switched to a different branch of the class hierarchy. All three operations are subject to the same restriction.
