Q131.
In UML terminology, the process of tracing is called ____

a.

context diagram

b.

context flow

c.

use-case analysis

d.

event flow

Discuss
Answer: (c).use-case analysis Explanation:A trace of the path created by stimulus-response event pair is called thread. In UML terminology, the tracing of the interactions among external actors and the encapsulated system is called use case analysis.
Q132.
_____ thread must be completed within a short window.

a.

Isochronous

b.

Near-real-time data packets

c.

Non-critical

d.

Use-case analysis

Discuss
Answer: (a).Isochronous Explanation:Signal flow is an isochronous stream. Isochronous thread must be completed within a short window. Isochronous threads tend to be classes with timing constraints especially in multiple inheritance object oriented environment.
Q133.
Enterprise architectures should promote ____ paths among object representations.

a.

evolution

b.

progression

c.

continuity

d.

migration

Discuss
Answer: (d).migration Explanation:Enterprise architecture promotes standard classes and facilitates reusable objects. Enterprise architectures should promote migration paths among object representations. Enterprise architecture is open for alternatives to prevent inappropriate suppression of software definition approach.
Q134.
Setup and control is a message useful for object interfaces.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:The proper format (syntax) and meaning (semantics) of messages are necessary for successful integration of software and hardware. Setup and control, state and state transition, information stream with specific timing constraint, timing and frequency standard information are examples of useful messages for object interfaces.
Q135.
The degree of “reach” required is determined by the number of the software components.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:The degree of “reach” required is determined by the scope of the software components. If an object is locally defined, then team level agreement on data and behavior is sufficient. If it were to extend among multiple teams, agreement on a large scale is required.
Q136.
The channel object obtains system resources for the _____

a.

channel

b.

mode

c.

band

d.

waveform

Discuss
Answer: (d).waveform Explanation:The channel object may be organized as a set of software objects that carry out the assigned sub-system level functions of RF control, modem processing, INFOSEC, and internetworking. The channel object obtains system resources for the waveform.
Q137.
____ are the functional objects that implement the personalities of channel objects.

a.

Agents

b.

Ghost objects

c.

Modem objects

d.

Modem events

Discuss
Answer: (a).Agents Explanation:Agents are the functional objects that implement the personalities of channel objects. It may be organized around the top-level system functions of RF control, modem processing, etc. It may also serve as hosts for buses, manage IO processes, etc.
Q138.
System control handles ____

a.

message processing

b.

protocol stacks

c.

boot-up

d.

internetworking

Discuss
Answer: (c).boot-up Explanation:Message processing, managing protocol stacks and internetworking are examples of back-end objects. System control handles system boot-up, initial time of day, current hop, etc.
Q139.
Which of the following is not a stage of a state machine?

a.

Waiting for instantiation

b.

Waiting for timer

c.

Fetching the waveform

d.

Waiting for response

Discuss
Answer: (b).Waiting for timer Explanation:A state machine is any device that stores a status for a given time. The status may change according to the input. Waiting for instantiation, fetching the waveform, and waiting for response are the three stages of a state machine. Conditions for switching from one state to another are a part of the state machine.
Q140.
_____ can be in exactly one of a countable number of states at any given time.

a.

Push-down automata

b.

Agent state machine

c.

Finite state machine

d.

Infinite state machine

Discuss
Answer: (c).Finite state machine Explanation:A state machine is any device that stores a status for a given time. It consists of a finite set of distinct states, a set of inputs, a set of outputs, a next state map and an output map. Finite state machine can be in exactly one of a finite number of states at any given time.
