Cisco CCDE 400-007 Questions & Answers

• Question 121:

  Which actions are performed at the distribution layer of the three-layer hierarchical network design model? (Choose two)

  A. Fast transport

  B. Reliability

  C. QoS classification and marking boundary

  D. Fault isolation

  E. Redundancy and load balancing

  Correct Answer: DE

• Question 122:

  A financial company requires that a custom TCP-based stock-trading application be prioritized over all other traffic for the business due to the associated revenue. The company also requires that VoIP be prioritized for manual trades. Which directive should be followed when a QoS strategy is developed for the business?

  A. Allow VoIP and the custom application to share the same priority queue,

  B. The custom application and VoIP must be assigned their own separate priority queue.

  C. Interleave the custom application with other TCP applications in the same CBWR

  D. Avoid placing the custom application in a CBWFQ queue that contains other

  Correct Answer: B

  Assigning separate priority queues for the custom application and VoIP ensures that they are given the highest priority and can be transmitted with minimal delay, regardless of the traffic congestion on the network.

• Question 123:

  A small organization of 20 employees is looking to deliver a network design service for modernizing customer networks to support advanced solutions.

  1.

  Project scope and weekly progress should be visualized by the management.

  2.

  Always consider feedback and make changes accordingly during the project.

  3.

  Should consider flexibility to change scope at the point of time.

  Which project methodology meets the requirements and have the least impact on the outcome?

  A. Scrum

  B. LEAN

  C. Kanban

  D. Six-Sigma

  Correct Answer: C

  while Scrum could be a viable option, Kanban's emphasis on visualization, continuous improvement, and flexibility to change scope during the project makes it a better fit for the specific requirements mentioned in the question.

The team also analyzes enterprise telemetry data from IPFIX data records that are received from devices in the campus network. Which action can be taken based on the augmented data?

  A. reduction in time to detect and respond to threats

  B. integration with an incident response plan

  C. adoption and improvement of threat-detection response

  D. D. asset identification and grouping decisions

  Correct Answer: A

• Question 128:

  As part of workspace digitization, a large enterprise has migrated all their users to Desktop as a Sen/ice (DaaS), by hosting the backend system in their on-premises data center. Some of the branches have started to experience disconnections to the DaaS at periodic intervals, however, local users in the data center and head office do not experience this behavior. Which technology can be used to mitigate this issue?

  A. tail drop

  B. traffic shaping

  C. WRED

  D. traffic policing

  Correct Answer: B

• Question 129:

  A. It protects against routing loops.

  B. It switches traffic immediately after a link failure.

  C. lt speeds up link failure detection.

  D. It reduces the utilization of system processing resources.

  E. It improves overall network stability.

  Correct Answer: DE

• Question 130:

  Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two)

  A. cost optimization approach

  B. strategic planning approach

  C. modular approach

  D. tactical planning approach

  E. business optimization approach

  Correct Answer: BD

  Planning Approaches To develop a successful network design, a proper planning approach is required to build a coherent strategy for the overall design. Network designers can follow two common planning approaches to develop business-driven network designs and facilitate the design decisions:

  1.

  Strategic planning approach: Typically targets planning to long-term goals and strategies. For example, a service provider needs to migrate its core from legacy (ATM) to be based on MPLS instead. The design decision in this approach has to cater to long-term goals and plans.

  2.

  Tactical planning approach: Typically targets planning to overcome an issue or to achieve a short-term goal. For instance, an enterprise might need to provide remote access to some partners temporally (for example, over the Internet) until dedicated extranet connectivity is provisioned. Design decisions in this approach generally need to provide what is required within a limited period of time and are not necessarily required to consider long-term goals.
