1In UML 2.5, what is a Class?

A.A classifier that describes a set of objects sharing the same features, constraints, and semantics

B.An instance of an object at runtime

C.A package containing related diagrams

D.A behavior that executes a single operation

Explanation: A Class is a Classifier that describes a set of objects sharing the same features (attributes and operations), constraints, and semantics. Instances of a Class are objects. It is the central modeling element on a class diagram.

2Which UML symbol denotes composite aggregation (composition) between two classes?

A.A filled (solid black) diamond at the whole end of the association

B.A hollow (open) diamond at the whole end of the association

C.An open triangular arrowhead at the whole end

D.A dashed line with a stereotype keyword

Explanation: Composite aggregation (composition) uses a filled diamond at the whole (composite) end. The whole is responsible for the lifecycle of its parts. Shared aggregation uses a hollow diamond; plain association has no diamond.

3An association end is marked with the multiplicity 1..*. What does this mean?

A.One or more instances are required at this end

B.Exactly one instance is required at this end

C.Zero or one instances are allowed at this end

D.Any number of instances including zero is allowed

Explanation: Multiplicity 1..* means at least one and any larger number (no upper bound). 1 = exactly one. 0..1 = optional (zero or one). * or 0..* = any number including zero.

4In UML 2.5, what is the difference between shared aggregation and composite aggregation?

A.Composite implies the whole owns and controls the lifecycle of its parts; shared aggregation has weaker, unspecified ownership semantics

B.Shared aggregation always uses a filled diamond; composite uses a hollow diamond

C.Composite aggregation is only allowed in n-ary associations

D.Shared aggregation forbids any multiplicity greater than one

Explanation: In composite aggregation the whole has strong ownership and lifecycle responsibility for the parts (parts cannot belong to two composites and die with the whole). Shared aggregation is a weaker form whose precise semantics is left to the application or profile.

5Which UML class diagram element represents a generalization relationship?

A.A solid line with a hollow (open) triangular arrowhead at the parent class

B.A dashed line with a hollow triangular arrowhead at the parent class

C.A solid line with a filled diamond at the parent class

D.A dashed line with an open stick arrowhead at the parent class

Explanation: Generalization (inheritance) is shown as a solid line with a hollow triangular arrowhead pointing to the parent (more general) classifier. A dashed line with the same arrowhead would be Realization (e.g., interface realization), not Generalization.

6How is an abstract class shown in UML notation?

A.Class name in italics, or annotated with {abstract}

B.Class name underlined

C.Class name in bold uppercase

D.Class drawn with a dashed outline

Explanation: An abstract class has its name displayed in italics; equivalently the constraint {abstract} can be shown after the name. Underlined names denote static (class-scope) features, not abstract classifiers.

7An attribute is shown as 'count : Integer = 0'. What does the 0 represent?

A.The default value of the attribute

B.The lower multiplicity bound

C.The visibility marker

D.The unique identifier of the attribute

Explanation: The syntax is visibility name : type [multiplicity] = default {properties}. Here '= 0' is the default value the attribute takes when an instance is created without explicit initialization.

8What does an underlined attribute or operation name in a class indicate?

A.It is class-scoped (static) — it belongs to the classifier itself rather than to instances

B.It is abstract and must be implemented by subclasses

C.It is read-only (constant)

D.It is derived from other attributes

Explanation: Underlining denotes class scope (static): the feature belongs to the classifier and is shared across all instances, rather than belonging to each instance individually. Abstract is italic; derived is a leading slash '/'.

9In an operation signature 'transfer(amount : Money, target : Account) : Boolean', what is 'Boolean'?

A.The return type of the operation

B.The default value of the last parameter

C.The visibility of the operation

D.An inherited stereotype

Explanation: The operation syntax is visibility name(param-list) : return-type {properties}. After the closing parenthesis, the type following ':' is the return type. Here Boolean is the type of the value returned by transfer.

10Which UML relationship is shown as a dashed line with an open stick arrowhead pointing to the supplier?

A.Dependency

B.Generalization

C.Composition

D.Association

Explanation: Dependency is a dashed line with an open stick arrowhead pointing from the dependent (client) to the supplier. Generalization uses a solid line with a hollow triangle; realization uses a dashed line with a hollow triangle; association is a plain solid line.

OCUP 2 Foundation Study Tips from Top Performers

1Memorize the four UML association forms: plain Association (no diamond), shared Aggregation (hollow diamond, weak whole-part), composite Aggregation (filled diamond, strong whole-part, lifecycle dependency), and n-ary association (multi-end diamond)

2Master Include vs Extend direction: Include arrow points FROM the base use case TO the included one (base needs included); Extend arrow points FROM the extension TO the base (extension is optional/conditional)

3Know the multiplicity notation cold: 1 (exactly one), 0..1 (optional), 0..* or * (any number), 1..* (one or more), m..n (between m and n)

4Distinguish Activity Final (terminates the entire activity) from Flow Final (terminates only that token), and DecisionNode (one in, branches out) from MergeNode (branches in, one out)

5Sequence diagram messages: solid filled arrow = synchronous call, solid open arrow = asynchronous, dashed open arrow = reply, dashed «create» = object creation, X on lifeline = destroy

6CombinedFragment operators: alt (alternative branches), opt (single optional path), loop (iteration), par (parallel), break (break out of enclosing), neg (forbidden sequence), critical (atomic), assert (only valid sequence), seq/strict (ordering)

7Visibility shorthand: + public, - private, # protected, ~ package — these prefixes apply uniformly to attributes and operations across UML

Frequently Asked Questions

What is the OCUP 2 Foundation exam?

The OMG-OCUP2-FOUND100 (OMG Certified UML Professional 2 — Foundation) is the entry-level certification in OMG's three-tier OCUP 2 program. It validates foundational knowledge of UML 2.5 notation and semantics across class, use case, activity, and sequence diagrams, plus basic packages, components, object diagrams, and common behavior.

How many questions are on the exam and how long is it?

The exam has 90 multiple-choice questions. Candidates in native English-speaking countries get 90 minutes; candidates in all other countries get 120 minutes. Some questions reference UML diagrams. The passing score is 62 out of 90, approximately 69%.

How much does the OCUP 2 Foundation exam cost?

Per OMG's official exam overview, the fee is US$250 (or local equivalent) in English-speaking countries and US$260 in others. Retakes cost US$175 / US$185. The exam is delivered through Pearson VUE at test centers or via online proctoring.

Are there prerequisites?

No prerequisites — Foundation is the entry point of the OCUP 2 program. Passing it is a prerequisite for both the OCUP 2 Intermediate and OCUP 2 Advanced exams.

What are the largest topic areas?

Per OMG's coverage map: Classes (~20%), Other UML Constructs including packages/components/objects (~20%), Common Structure (~15%), Use Cases (~15%), Activities (~10%), Interactions (~10%), and Common Behavior (~10%). Foundation focuses on notation and basic semantics, not metamodel internals.

How long is the certification valid?

OCUP 2 certifications are valid for 5 years from the date you pass. To extend, you must pass the same level or a higher-level exam before expiration. You can retake the exam 30 days after your previous attempt, with a maximum of three attempts in a 12-month window.

What is the difference between OCUP 2 Foundation and the old OCUP 1?

OCUP 2 is built on UML 2.5 and uses three conformance-aligned levels (Foundation, Intermediate, Advanced). The legacy OCUP 1 program was built on UML 2.1 with four levels (Fundamental, Intermediate, Advanced, Expert). OCUP 1 was retired in 2017; only OCUP 2 is currently active.

How should I prepare?

Plan for 4-6 weeks of study. Read the UML 2.5.1 specification chapters listed in the exam overview (Common Structure, Classification, SimpleClassifiers, StructuredClassifiers, Packages, UseCases, Activities, Interactions), use the recommended OCUP 2 Foundation guide (Weilkiens), and practice with at least 100 questions targeting 80%+ on timed mocks.
