• Question 141:

  What best describes the distinction between a delegation connector and an assembly connector?

  A. A delegation connector can be used to model the internals of a component, while an assembly connector cannot.

  B. Assembly connectors provide white box views of components, while delegation connectors provide black box views.

  C. An assembly connector connects two components while a delegation connector connects the internal contract of a component with its external parts.

  D. An assembly connector connects the required interface or required port of one component with the provided interface or provided port of another component, while a delegation connector connects the external contract of a component with its internal parts.

  Correct Answer: D

• Question 142:

  Correct Answer: D

• Question 143:

  Refer to the exhibit.

  What is the significance of the fact that the Administration interface symbol extends downward rather than

  leftward?

  

  A. There is no significance.

  B. The interface cannot be provided via a port.

  C. The interface does not require a delegation connector.

  D. The interface is not publicly visible on the component.

  E. The interface is the primary interface for the component.

  F. The interface is the primary provided interface for the component.

  Correct Answer: A

• Question 144:

  What does the composite structure exhibit show?

  

  A. The diagram is not valid.

  B. The two F interfaces must come from different packages.

  C. Requests for behavioral features of interface F through ports p1 and p2 can be distinguished.

  D. Requests for behavioral features of interface F through ports p1 and p2 will always result in the same behavior.

  Correct Answer: C

• Question 145:

  What is NOT true about a roles and role bindings?

  A. A role binding is an association.

  B. The same object may play roles in multiple collaborations.

  C. A role binding maps a connectable element to a role in a collaboration occurrence.

  D. The same connectable element may be bound to multiple roles in a single collaboration occurrence.

  E. A role typed by an interface specifies a set of features required by a participant in a collaboration.

  Correct Answer: A

• Question 146:

  Which list contains only connectable elements?

  A. port and connector end

  B. behavior, port and property

  C. connector end, port and part

  D. property, port, and parameter

  E. behavior, connector end, and port

  Correct Answer: D

• Question 147:

  What does the composite structure notation in the exhibit mean?

  

  A. Class C has internal structure.

  B. Object c1 is a kind of component.

  C. Port p is connected to an object called F

  D. Port p realizes the features defined by interface F

  E. Port p requires the features defined by interface F

  Correct Answer: E

• Question 148:

  Which is true of a provided interface associated with a port?

  A. represents an interface that must be defined within the classifier that owns the port

  B. identifies the services that the object owning the port expects of objects connected via that port

  C. identifies the services that the object owning the port can offer to other objects connected via that port

  D. represents an interface that must be defined in the same package in which the classifier owning the port is defined

  Correct Answer: C

• Question 149:

  What is NOT a purpose of a port owned by a classifier?

  A. serves as an end point for connectors

  B. specifies an association to the classifier

  C. hides the internals of that classifier from other classifiers

  D. provides a distinct point of interaction between the classifier and its environment

  Correct Answer: B

• Question 150:

  What is an invocation action on a port used for?

  A. sending a message to that port

  B. receiving a message on that port

  C. creating a link and attach it to that port

  D. relaying the invocation via links connected to that port

  E. invoking the behavior of the classifier that owns the port

  Correct Answer: D
