Software Architecture and Design Practice Test 4

1. What among these follows acceptor model?

A common use of models is to design a lexical analyzer, which is a program component that transforms a character stream into a stream of tokens, which are symbols recognized by the program

None of the mentioned

All of the mentioned

They often model the behavior of small software modules

2. What is break fragment?

An fragment which has one or more guarded operands whose guards are mutually exclusive—that is, at most one of them can be true at any time

A fragment which has a single operand that may or may not have a guard

A fragment which has a single operand that is performed instead of the remainder of the enclosing fragment or diagram if the operand guard is true

None of the mentioned

3. Which of the following are the ways to make transitions into and two ways to make transitions from concurrent composite states?

All of the mentioned

A transition into a concurrent composite state is to make a transition directly to one of its sub-states

A transition is made to the composite state boundary

None of the mentioned

4. Which of the following is data responsibility?

An Obligation to know something that is to maintain some data

An Obligation to do something that is to carry out some tasks

None of the mentioned

All of the mentioned

5. Why does designers look for candidate classes?

To model entities in charge of or involved in program tasks

All of the mentioned

To model structures and collections of objects

To model things in the world that interact directly with the program

6. What is Delegation?

All of the mentioned

The tactic where in a module en thrusts another module with responsibility is called delegation

Delegation not only allows reuse without inheritance but also provides a mechanism to make software much more flexible and configurable

None of the mentioned

7. Which of the following are the uses for Dialog maps?

None of the mentioned

All of the mentioned

They can be used to help elicit stakeholder needs and desires and to model them to make sure they are well understood and documented

Dialog maps are useful whenever the behavior of a program’s user interface is under study

8. After generating candidate classes, designers evaluate them and choose the best ones to include in the model using the which of the following heuristics?

Apply design patterns where appropriate

All of the mentioned

Discard candidates that do something out of scope

Discard candidates with vague names or murky responsibilities

9. Which of the statements state the name compartment?

The first compartment is the name compartment, It contains the state name; State names are optional and may be path names

The name compartment can never be omitted

It contains the state name; State names are optional and may be path names

The first compartment is the name compartment

10. What are the three different types of message arrows?

Synchronous, asynchronous, asynchronous with instance creation

Self, Multiplied, instance generator

None of the mentioned

Synchronous, Asynchronous, synchronous with instance creation
