Exam OMG-OCUP2-FOUND100 Topic 1 Question 55 Discussion

Actual exam question for OMG's OMG-OCUP2-FOUND100 exam
Question #: 55
Topic #: 1
Choose the correct answer:
Which diagram is invalid?

Suggested Answer: C Vote an answer

Option C shows a UML diagram where a class (One) appears to have an aggregation relationship with itself.
In UML, an aggregation is a special type of association that represents a whole-part relationship between the aggregate (whole) and a component part. However, it does not make sense for a class to aggregate itself; such a relationship implies that instances of the same class are parts of each other, which is conceptually invalid.
Let's consider the other options: A) This diagram shows a class contained within another, which is a valid use of nesting classes. B) This diagram shows a composition relationship, which is a form of aggregation with a stronger lifecycle dependency between the whole and the part. This is a valid relationship in UML. D) This diagram shows a class containing two nested classes, one of which contains another nested class. This is also a valid representation of nested classes in UML.
Therefore, the correct answer is:
C: Option C
