Q91.
What role do causal relations between program components play in the maintenance of a system?

a.

They have no role in maintenance activities

b.

They are not important

c.

They play an important role

d.

They only play a role in implementing changes

Discuss
Answer: (c).They play an important role Explanation:The causal relations between program components play an important role in the maintenance of a system, especially when implementing changes.
Q92.
What increases the probability of ripple effects when modifying a system?

a.

Use of the systematic strategy

b.

Use of the as-needed strategy

c.

Use of a bottom-up approach

d.

Use of a top-down approach

Discuss
Answer: (b).Use of the as-needed strategy Explanation:The use of the as-needed strategy increases the probability of ripple effects when modifying a system.
Q93.
What is the origin of the knowledge used by the programmer during the comprehension process?

a.

Within the program text proper

b.

From external sources

c.

From local clues only

d.

From the systematic study of the program text

Discuss
Answer: (b).From external sources Explanation:During the comprehension process, the programmer uses knowledge that has its origin outside the program text proper.
Q94.
What are the classes of tools used during the reverse engineering process to build an understanding of the software?

a.

Tools to ease perceptual processes and gain insight into the static structure of the program

b.

Tools to generate tables of contents and cross-reference listings

c.

Tools to analyze the version history of the system

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Several classes of tools may support the task of program understanding such as tools to ease perceptual processes, gain insight into the static structure of the program, inspect the version history of the system, etc.
Q95.
What do tools that ease perceptual processes do?

a.

Generate a neat lay-out of the code

b.

Compute software complexity metrics

c.

Highlight 'dead code'

d.

Provide powerful interactive capabilities for inspecting the static structure of the program

Discuss
Answer: (a).Generate a neat lay-out of the code Explanation:Tools that ease perceptual processes produce a neat layout of the code in which nested instructions are indented and blank lines are put between successive methods.
Q96.
What do tools that gain insight into the static structure of the program do?

a.

Print procedure names in a larger font

b.

Generate a graphical image of a program text

c.

Highlight components that have been changed frequently

d.

Provide mechanisms to extend the traditional flat organization of text by their capabilities for linking non-sequential chunks of information

Discuss
Answer: (d).Provide mechanisms to extend the traditional flat organization of text by their capabilities for linking non-sequential chunks of information Explanation:Hypertext systems provide mechanisms to extend the traditional flat organization of text by their capabilities for linking non-sequential chunks of information and thus help to gain insight into the static structure of the program.
Q97.
What do tools that inspect the version history of the system do?

a.

Highlight components that have been changed very often

b.

Indicate weak spots in the software architecture

c.

Cluster parts that seem to be highly related

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:Tools that inspect the version history of the system may highlight components that have been changed very often, indicating candidates for reengineering, and identify pairs of components that have often changed together but are not logically related, indicating weak spots in the software architecture.
Q98.
What are the tools to gain insight into the dynamic behavior of programs?

a.

Tools to ease perceptual processes involved in program understanding

b.

Tools that generate tables of contents and cross-reference listings

c.

Traditional text-oriented debugging systems

d.

Tools for design recovery

Discuss
Answer: (c).Traditional text-oriented debugging systems Explanation:Next to traditional text-oriented debugging systems there are systems which provide graphical capabilities to monitor program execution.
Q99.
What is the classification of tools that provide support for maintenance tasks?

a.

Redocumentation tools

b.

Tools for design recovery

c.

Tools for restructuring program code

d.

Maintenance apprentice

Discuss
Answer: (a).Redocumentation tools Explanation:With respect to reverse engineering, the above tools may be classified as redocumentation tools.
Q100.
What is the feasibility of completely automatic design recovery?

a.

Feasible

b.

Not feasible

c.

Can't say

d.

None of the above

Discuss
Answer: (b).Not feasible Explanation:Completely automatic design recovery is not feasible for the foreseeable future.
