Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2ArchitectureEasy
A network engineer is designing a new campus network for a university. The design requires a scalable and flexible solution that can segment student, faculty, and guest traffic while providing automated policy enforcement and simplified network management. Which network architecture best meets these requirements?
- ACisco SD-Access
- BFlat Layer 2 network with VLANs
- CTraditional three-tier hierarchical network
- DDistributed Wireless Mesh Network
Show answer & explanationAnswer & explanation
Correct answer: A. Cisco SD-Access
Cisco SD-Access provides an intent-based networking solution that automates network segmentation, policy enforcement, and simplifies management, which aligns perfectly with the requirements for a scalable, flexible, and secure university campus network.
Why the other options are wrong
- B. A flat Layer 2 network with VLANs becomes complex to manage and scale, and lacks automated policy enforcement for dynamic segmentation.
- C. A traditional three-tier network lacks the automation and dynamic segmentation capabilities required.
- D. A distributed wireless mesh network focuses on wireless connectivity and does not inherently provide the required segmentation and management automation for a campus-wide wired and wireless solution.
Cisco SD-Access
Cisco Software-Defined Access (SD-Access) is an intent-based networking solution that automates network access, simplifies policy enforcement, and provides end-to-end segmentation for wired and wireless networks.
- Automates network provisioning and policy application.
- Provides end-to-end segmentation using Virtual Networks (VNs) and Scalable Group Tags (SGTs).
- Leverages an underlay (physical network) and an overlay (VXLAN-based virtual network).
