Discuss OMG OMG-OCUP2-ADV300 Exam Topic 8 Question 36

Choose the correct answer:

What does a lower multiplicity of one for an end of an n-ary Association imply?

ALinks combining the values of the other ends may exist or may not exist

BExactly one link exists combining the values of the other ends.

CA link for every possible combination of values for the other ends must exist.

DLinks combining the values of one or many other ends may exist.

Suggested Answer: A

In UML, the multiplicity of an association end specifies how many instances of the class at that end can participate in a single association. A lower multiplicity of one (1) at one end of an n-ary (where n > 2) association implies that there must be at least one link that combines the values of the other ends, but it doesn't require that a link exists for every possible combination. Therefore, it's possible for some combinations to exist as links, while others do not, which is indicated by the option that links combining the values of the other ends may exist or may not exist. This interpretation is consistent with the definition of multiplicity in associations as outlined in the UML 2.x Superstructure Specification.

Wait, are we sure about this? D sounds kinda right too.

Nah, I feel like it's A. Could be more flexible.

I think it's definitely B. Exactly one link!

C seems too strict. Not every combo needs a link.

Loreta 11 months ago

I feel like option B is the right choice because it talks about exactly one link, which seems to fit the definition of lower multiplicity.

Nydia 11 months ago

I’m confused about this one. I thought lower multiplicity meant there could be multiple links, but now I’m not so sure.

Merrilee 11 months ago

I remember practicing a question like this where it was about the existence of links. I feel like option A might be correct since it suggests links may or may not exist.

Aileen 11 months ago

I think a lower multiplicity of one means there has to be exactly one link, but I'm not entirely sure.

Amie 12 months ago

This one's tricky, but I think I've got it. A lower multiplicity of one means there's exactly one link, so the answer has to be B. I'm pretty confident about that.

Asuncion 12 months ago

I'm feeling good about this question. The key is understanding what "lower multiplicity of one" means. Based on that, I think the correct answer is B.

Eulah 12 months ago

Okay, let me see if I can break this down. A lower multiplicity of one means there's only one link, so I think the answer is B. But I want to double-check the other options just to be sure.

Hmm, I'm a little unsure about this. I'm debating between A and B, but I'm not totally sure. I'll have to think it through carefully.

Angelyn 1 year ago

I'm pretty confident about this one. I think the answer is B - exactly one link exists combining the values of the other ends.
