350-401 Question 6
Select 3An enterprise network is being designed to ensure scalability, resiliency, and optimized performance across multiple branches. The network architect decides to deploy a hierarchical design model. Which design principles align with this approach?
- A
Implementing a core, distribution, and access layer architecture
- B
Prioritizing a flat network for easier management
- C
Ensuring redundancy in critical network paths
- D
Centralizing all traffic through a single data center
- E
Using modularity to simplify troubleshooting and scaling
Show answer and explanation
Correct answers: A, C, E
Explanation
The hierarchical design model in an enterprise network focuses on scalability, resiliency, and performance. Key principles include implementing a core, distribution, and access layer architecture, ensuring redundancy in critical paths, and using modularity to simplify network management and scaling. Flat networks and single points of traffic concentration introduce limitations and do not align with these principles.
- A. Correct.
Correct: The hierarchical design model is based on a core, distribution, and access layer architecture to ensure scalability, performance, and efficient traffic management.
- B. Incorrect.
Incorrect: A flat network is not recommended for an enterprise as it can lead to scalability and performance issues, especially in larger networks.
- C. Correct.
Correct: Redundancy is a key principle in enterprise networks to ensure resiliency and high availability, especially in critical paths.
- D. Incorrect.
Incorrect: Centralizing all traffic through a single data center creates a bottleneck and does not align with the principles of scalability and fault tolerance.
- E. Correct.
Correct: Modularity simplifies troubleshooting and scaling by allowing the network to be divided into smaller, manageable components.
