350-401 Question 8
Select 3An enterprise network is being designed to support high availability, scalability, and efficient traffic flow. Which design principles should be prioritized to meet these requirements?
- A
Hierarchical design with core, distribution, and access layers
- B
Flat network design to simplify configuration
- C
Scalability to support future growth
- D
Centralized single-point-of-failure design for easier troubleshooting
- E
Redundancy to ensure high availability
Show answer and explanation
Correct answers: A, C, E
Explanation
Enterprise networks are designed to support business-critical applications, requiring a focus on structured, scalable, and redundant architectures. Hierarchical design ensures efficient management and traffic flow, scalability supports future growth, and redundancy guarantees high availability. Flat designs and single points of failure should be avoided as they compromise these objectives.
- A. Correct.
Hierarchical design with core, distribution, and access layers helps organize the network into layers, enhancing scalability, efficient traffic flow, and management of high availability.
- B. Incorrect.
Flat network design is not recommended for enterprise networks as it can lead to scalability and performance issues while increasing the risk of network outages.
- C. Correct.
Scalability is a key design principle in enterprise networks to ensure the network can accommodate growth, new applications, or additional users without major redesigns.
- D. Incorrect.
Centralized single-point-of-failure design contradicts the principle of high availability, as a single failure can bring down the entire network.
- E. Correct.
Redundancy is critical for maintaining high availability, ensuring that the network can continue functioning even in the event of device or link failures.
