QUESTION: 37

Choose the correct answer :
Given the following diagram fragment:

Which review comment is valid and applicable?

The Realization relationships should be reversed
The Generalization relationships should be replaced by Realization relationships.
The Realization relationships should be replaced by Generalization relationships.
The UML syntax rules do not allow the use of Realization relationships between Components and Classes without the application of the stereotypes in a profile.

Answer(s): C

Explanation:

The provided diagram fragment shows what appears to be Components or Classes with dashed arrows pointing towards them. Typically in UML, a dashed arrow with an unfilled arrowhead represents a Realization relationship, which is used to show that an element (such as an interface) is realized by another element (such as a class or component). However, when we are talking about Classes like "EventRegistration," "MessagePacket," "Attendee," and "Session" which seem to share a common nature or purpose with "EmailServices," these relationships are more appropriately modeled as Generalizations, indicating that they inherit from a common superclass or implement a common interface. Realizations are typically not used in this context. Hence, the dashed arrows in the diagram should be solid lines representing Generalization, not Realization. This answer aligns with the UML 2.x Superstructure Specification, which provides guidance on the usage of Realization and Generalization relationships in class diagrams.

QUESTION: 38

Choose the correct answer :
Consider the following diagram:

What kind of model element is chentNo?

a Port of Class ExamCompany
a qualifier of the Association
a Property defined by Association and owned by the Class ExamCompany
a Property defined by Association and owned by the Class Examinee

Answer(s): B

Explanation:

In the context of the diagram, "clientNo" is placed next to the association line between "ExamCompany" and "Examinee," which indicates that "clientNo" is a qualifier of the association. In UML, a qualifier is used to refine the association between two classes by providing a way to access linked objects based on some attribute value. The qualifier essentially acts as a key in an associative array or map, allowing access to instances of the associated class. In this case, "clientNo" is likely used to uniquely identify examinees associated with an exam company. This use of qualifiers is detailed in the UML 2.x Superstructure Specification, which describes how qualifiers can be used to specify refined access to linked objects within an association.

QUESTION: 39

Choose the correct answer : Consider the following piece of UML definition:

What is the typing of xx. xy and result?

xx Cattle. xy:Bull. resultCattle
xx:Cow, xy:CattlG, result;Donor
xx:Cow. xy:Cattle. result:Cattle
xxCow. xv Bull. resultCattle

Answer(s): C

Explanation:

The UML diagram illustrates two types of reproduction for cattle: natural and assisted. In natural reproduction, a bull (xy) and a cow (xx) result in a new cattle (result), which aligns with biological principles. The same principle applies to assisted reproduction, where the donor is also cattle (xy), and the result is a new cattle. Since both Ferd Bull and Don Donor are specialized types of Cattle, and the result of both reproductions is Cattle, it implies that both xx and xy are of type Cattle, but within the context, xx is specifically a Cow. Therefore, xx is a Cow, xy is Cattle (which can be a Bull or Donor), and the result is also Cattle. This interpretation aligns with the principles of UML where specific instances (like Ferd Bull and Don Donor) are instances of the more general classifier Cattle.

QUESTION: 40

Choose the correct answer : Consider the following diagram fragment:

Assume that the system is in StateAl Which sequence of triggers will move the system to StateC?

a6., a3, a1, a7, an
a5, a5, a5. a1. a8, a8, a11
a5, a6, a5, a3, a2, a10, a11, a12
D a1, a7, a8, a7, an

Answer(s): C

Explanation:

Given that the system is in StateA1, the sequence of triggers that will move the system to StateC must take into account the transitions and their associated triggers as defined in the UML state diagram. Starting from StateA1, the trigger a5 will cause a transition within StateA, followed by a6, which moves to StateA2. The trigger a5 is not relevant as it is an internal transition in StateA1. Then, a3 (the exit action for StateA) and a2 would be followed to leave StateA altogether. Once out of StateA, a1 is used to transition to StateB, where a10 is an entry action, not a trigger. Finally, to get from StateB to StateC, the triggers a11 followed by a12 are needed. This sequence of triggers reflects the correct usage of exit, entry, and transition triggers as defined by UML state machine semantics.
