Answer 1

the activities are being allocated to the block .

what does it mean to allocate one element to another ?

Question 2

allocation requires abstract thought. As flexibility increases , usability is diminished.
it has no formal semantics defined in the language. responsibility falls on the modler on how to use allocation.

Question 7

1. package
2. requirements
3. states

Question 9

two alternative techniques that convey better information than an a behavioral allocation are
1. owned behaviors - nested under an activity strongest form of behavioral allocation
2. mapping with configuring an element in the specification window

Question 10

structural allocation means allocation of a ______ to a structural element.

reference property allocated to part property
logical to physical mapping
block allocated to block

Answer 10

structural

Question 11

Notations for allocation relationships
1. direct notation
2. compartment notation
3. callout notation
4. matrices
5. tables
6. _________ activity partition

Answer 11

allocations

Question 12

what is the advantage of using a direct notation for allocations ?

Answer 12

easy for the reader to understand who is the supplier and who is the client

Question 13

compartment notation for allocation relationships .. compartment like style in the diagram is another way of showing allocation. This notation is more direct

How would you read the Measure altitude activity ?

Answer 13

     ------------                                                ------->

Question 14

Note: callout notation can be anchored to any diagram .

Question 15

Review

Answer 16

behavioral

Question 17

table example for allocation relationship

Answer 17

here is an example in cameo

Question 18

allocation activity partitions (swimlanes)

how would you read the swimlane z-axisMC ?

Answer 18

the spin clockwise action is allocated to the z-axisMC structural property

Question 19

review

what kind of model element is display destination marker ?

Answer 19

call behavior action

Question 20

what kind of model element is display map marker ?

Answer 20

display destination marker is the call behavior action

display map marker is the behavior being called by call behavior action

Question 21

which model element is receiving an allocation ?

Answer 21

the call behavior action in the partition is being allocated
the responderVehicleDisplay is the structural element receiving the allocation

Question 22

scheme 1
requirement , resource , behavioral and structural allocation are the 4 types of allocation . the two common allocations seen in the exam are structural and behavioral.

scheme 2
allocation of definition - is an allocation of one element of definition to another
allocation of usage is an allocation of one element of usage to another
asymmetric allocation is an allocation of element of definition to a element of usage

Question 23

allocation of definition - is an allocation of ___________________________

Answer 23

of one element of definition to another
the answer is behavioral allocation of definition .

Question 24

allocation of usage is an allocation of ___________

Answer 24

of one element of usage to another
the answer is structural allocation of usage

Question 25

asymmetric allocation is an allocation of element of definition to a element of usage

Question 26

The exam will test you in these two schemes

Answer 26

Question 27
