Sample Questions for OMG-OCUP2-ADV300 Exam Preparation

Question 1

Choose the correct answer:

Consider the following sequence diagram GO:

OMG-OCUP2-ADV300 Exam Question 1 Exhibit 1

What is always true according to the diagram?

Ah receives x before k sends q

Bh receives q before k sends m

Ch receives q before g receives m

Dg sends x before k sends m

Correct : A

In the sequence diagram 'GO', the event 'h receives x' is depicted before 'k sends q', as indicated by the solid arrow from 'g' to 'h' labeled 'x' and the dashed arrow from 'k' labeled 'q'. Since messages are processed in the order they are depicted from top to bottom, 'h' must receive 'x' before 'k' can send 'q'.

The other options (B, C, and D) cannot be determined to be always true based on the information provided in the diagram alone. Especially with asynchronous messages, the send event may occur before the corresponding receive event, and the diagram does not contain sufficient information about timing constraints or message processing durations to ascertain the exact ordering of these events.

Reference include:

UML 2.5 Specification (formal/2017-12-05), specifically the sections regarding message sends and receives, lifelines, and the semantics of sequence diagrams.

Introduction to UML 2 Sequence Diagrams by Scott W. Ambler, which provides insights into the interpretation of sequence diagrams and the flow of messages.

Question 2

Choose the correct answer:

Consider the following sequence diagram:

OMG-OCUP2-ADV300 Exam Question 2 Exhibit 1

What does "critical" refer to?

AThat the emergency message is given highest priority

BThat the diagram fragment within 'critical may be up for redesign

CThat no other events may interfere m between the events of the critical fragment

DThat the most urgent and important issue is to make sure that Emergency gets the message

Correct : C

In UML 2, a ''critical'' section in a sequence diagram, like the one depicted, refers to a period where certain interactions are protected so that they can be executed without interruption or interference from other interactions (events). This is akin to a critical section in multi-threading where certain threads have exclusive access to resources or operations for a period of time. The correct answer is option C because it aligns with this definition: during the ''critical'' section on the sequence diagram, no other events may interfere between its events.
