350-401 Question 35
Select 4A network engineer is deploying a Cisco SD-WAN solution for a global enterprise. The engineer is tasked with ensuring secure communication between branch sites, centralized policy management, and optimal application performance. Which working principles of the Cisco SD-WAN solution play a critical role in achieving these requirements?
- A
Segmentation using VPNs for isolating traffic between branch sites
- B
Centralized control plane for policy enforcement and management
- C
Dynamic path selection based on application performance and link quality
- D
Integration with traditional MPLS to enable static routing
- E
End-to-end encryption for secure communication between sites
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Cisco SD-WAN is designed to provide secure, scalable, and efficient connectivity. Its key principles include traffic segmentation through VPNs, centralized control for policy management, dynamic path selection for optimal performance, and end-to-end encryption for ensuring secure communication. These capabilities allow organizations to meet security, performance, and operational goals effectively.
- A. Correct.
Segmentation using VPNs is a foundational principle of Cisco SD-WAN, allowing traffic isolation for security and compliance between various branches or business units.
- B. Correct.
The centralized control plane is a core feature of Cisco SD-WAN, enabling simplified and consistent policy enforcement and management across the entire network.
- C. Correct.
Dynamic path selection ensures optimal application performance by routing traffic based on real-time link quality and performance metrics.
- D. Incorrect.
While Cisco SD-WAN can integrate with MPLS, static routing is not a core principle of the solution, as it focuses on dynamic, intelligent routing.
- E. Correct.
End-to-end encryption ensures secure communication between sites, which is a critical requirement for protecting data in transit.
