CISCO CCDA 640-864 Chapter 1: Network Design Methodology

1. Budget and personnel limitations are examples of what?

Organizational requirements

Organizational constraints

Technical goals

Technical constraints

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.

2. Which design solution states that a design must start from the application later and finish in the physical layer?

OSI model

PPDIOO

Hierarchical architecture

Top-down

The top-down design approach starts the design from the application layer.

Explanation

The top-down design approach starts the design from the application layer.

3. Improving network response time and reliability are examples of what?

Organizational requirements

Organizational constraints

Technical goals

Technical constraints

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.

4. What are the three primary sources of information in a network audit?

CIO, network manager, network engineer

Network manager, management software, CDP

Network discovery, CDP, SNMP

Existing documentation, management software, new management tools

The primary sources of network audits are existing documentation, management software, and new management tools.

Explanation

The primary sources of network audits are existing documentation, management software, and new management tools.

5. At which point during the PPDIOO process are prototypes and pilots used?

As soon as the Design phase is complete but before the Implementation phase.

As soon as the Plan phase is complete and before the Design phase.

As soon as the Implementation phase is complete but before the Operate phase.

As soon as the Prepare phase is complete but before the Implementation phase.

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.

6. Which of the following is the correct order of the six phases of PPDIOO?

Prepare Plan Design Implement Operate Optimize

Plan Prepare Design Implement Operate Optimize

Prepare Plan Design Implement Optimize Operate

Plan Prepare Design Implement Optimize Operate

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.

7. Network resiliency and control occurs in which later of the borderless network architecture?

Policy and Control

Borderless Network Services

Borderless User Services

Connection Management

Network resiliency and control occurs in the Network Services layer

Explanation

Network resiliency and control occurs in the Network Services layer

8. Presence occurs in which collaboration architecture layer?

Communication and Collaboration

Collaboration Services

Infrastructure

Media Services

Presence occurs under Collaboration Services.

Explanation

Presence occurs under Collaboration Services.

9. Which of the following documentation should be updated during all phases of the PPDIOO life cycle?

The project plan

The implementation plan

The rollback plan

The operational plan

The network design plan

The project plan should be updated during all phases of the PPDIOO life cycle.

Explanation

The project plan should be updated during all phases of the PPDIOO life cycle.

10. Which of the following commands can you use to view current NetFlow statistics in Cisco IOS software?

The show ip flow cache command

The show ip cache flow command

The show ip flow command

The show ip netflow cache command

NetFlow provides extremely granular and accurate traffic measurements and a high-level collection of aggregated traffic. The output of NetFlow information is displayed via the show ip cache flow command.

Explanation

NetFlow provides extremely granular and accurate traffic measurements and a high-level collection of aggregated traffic. The output of NetFlow information is displayed via the show ip cache flow command.
