  2. decomposition
  3. computational thinking
  4. recursion
2 .
What shape in a flowchart represents a decision point?
  1. oval
  2. parallelogram
  3. rectangle
  4. diamond
3 .
What does pseudocode spell out in natural language?
  1. an algorithm
  2. a test case to debug
  3. a flowchart

4 .
After a test case fails, what is the next step to determine the cause of the failure?
5 .
What are the key elements of CT that distinguish CT from other types of problem-solving strategies?
6 .
What is the primary difference between a heuristic and a pattern?
  1. A heuristic is a general rule used for quick problem-solving when an exact solution is not possible, while a pattern is a repeatable solution to a commonly occurring problem.
  2. A heuristic and a pattern are both specific guidelines used to achieve exact solutions in complex problems.
  3. A heuristic is used for creating new designs, whereas a pattern refers to repeating decorative motifs.
  4. There is no difference; both terms refer to specific scientific methods used in research.

  1. system architecture
  2. technical architecture
  3. enterprise architecture
  4. solution architecture
8 .
What level of architecture is described as having a wider scope, a vague plan for the entire organization, and a higher level of abstraction?

9 .
What component holds the business logic for the business solution or application?
  1. presentation layer
  2. data management layer
  3. business logic layer

10 .
What is the difference between data, information, knowledge, and wisdom?
11 .
Explain why an information system architecture is considered an architecture view in TOGAF.
12 .
Once architectural similarities have been identified between the architecture of a new problem and existing architectural solutions, what is required to apply these patterns effectively?
  1. a comprehensive understanding of the new problem’s requirements and constraints
  2. the ability to modify existing patterns to fit the new problem’s unique context
  3. both a comprehensive understanding of the new problem’s requirements and the ability to modify existing patterns
  4. approval from a higher authority to use the identified patterns
