Which of the following is the correct order of the six phases of PPDIOO?
- A.
Prepare Plan Design Implement Operate Optimize
- B.
Plan Prepare Design Implement Operate Optimize
- C.
Prepare Plan Design Implement Optimize Operate
- D.
Plan Prepare Design Implement Optimize Operate
Correct Answer
A. Prepare Plan Design Implement Operate OptimizeExplanation
The correct order of the six phases of PPDIOO is Prepare, Plan, Design, Implement, Operate, Optimize. This order ensures that the necessary preparations are made before moving on to the planning phase. Once the plan is in place, the design phase takes place to create a detailed plan for implementation. After implementing the plan, the network or system is operated, and any necessary optimizations are made to improve its performance.Rate this question:

- B.
Design the network topology
- C.
Characterize the network
- D.
Optimize the network
- E.
Operate the network
- F.
Implement the network
- G.
Prepare and plan
Correct Answer(s)
A. Identify customer requirements
B. Design the network topology
C. Characterize the networkExplanation
The PPDIOO methodology has three steps.Rate this question:

What are the three primary sources of information in a network audit?
- A.
CIO, network manager, network engineer
- B.
Network manager, management software, CDP
- C.
Network discovery, CDP, SNMP
- D.
Existing documentation, management software, new management tools
Correct Answer
D. Existing documentation, management software, new management toolsExplanation
The primary sources of network audits are existing documentation, management software, and new management tools.Rate this question:

Which design solution states that a design must start from the application later and finish in the physical layer?
- A.
OSI model
- B.
PPDIOO
- C.
Hierarchical architecture
- D.
Top-down
Correct Answer
D. Top-downExplanation
The top-down design approach starts the design from the application layer.Rate this question:

Budget and personnel limitations are examples of what?
- A.
Organizational requirements
- B.
Organizational constraints
- C.
Technical goals
- D.
Technical constraints
Correct Answer
B. Organizational constraintsExplanation
Budget and personnel limitations are examples of organizational constraints. Organizational constraints refer to the limitations or restrictions that an organization may face in terms of resources, budgets, personnel, or other factors that can impact its operations and decision-making. In this case, the budget and personnel limitations act as constraints that the organization must work within, influencing its ability to allocate funds and human resources effectively.Rate this question:

Improving network response time and reliability are examples of what?
- A.
Organizational requirements
- B.
Organizational constraints
- C.
Technical goals
- D.
Technical constraints
Correct Answer
C. Technical goalsExplanation
Improving network response time and reliability are examples of technical goals. Technical goals refer to specific objectives that an organization sets to achieve in order to enhance the performance, efficiency, and effectiveness of its technical systems or infrastructure. In this case, the aim is to enhance the speed and reliability of the network, which aligns with the technical goals of the organization.Rate this question:

At which point during the PPDIOO process are prototypes and pilots used?
- A.
As soon as the Design phase is complete but before the Implementation phase.
- B.
As soon as the Plan phase is complete and before the Design phase.
- C.
As soon as the Implementation phase is complete but before the Operate phase.
- D.
As soon as the Prepare phase is complete but before the Implementation phase.
Correct Answer
A. As soon as the Design pHase is complete but before the Implementation pHase.Explanation
Prototypes and pilots are used as soon as the Design phase is complete but before the Implementation phase. This means that after the design has been finalized, prototypes and pilots are created to test and validate the design before it is fully implemented. This allows for any necessary adjustments or improvements to be made based on the feedback and results from the prototypes and pilots, ensuring a smoother implementation process.Rate this question:
