Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2ArchitectureMedium
A network architect is designing a new campus network for a large university. The design requires a highly scalable and resilient solution that can support thousands of wired and wireless endpoints, provide consistent policy enforcement, and simplify network operations across multiple buildings. Which architectural model best meets these requirements?
- ATraditional three-tier hierarchical design
- BFlat Layer 2 network with spanning tree protocol
- CDistributed autonomous AP deployment
- DCisco Software-Defined Access (SD-Access)
Show answer & explanationAnswer & explanation
Correct answer: D. Cisco Software-Defined Access (SD-Access)
Cisco SD-Access provides a highly scalable, resilient, and policy-driven network architecture that automates network provisioning and simplifies operations, making it ideal for large campus environments like a university.
Why the other options are wrong
- A. A traditional three-tier design, while common, lacks the automation, policy consistency, and simplified operations offered by SD-Access for large, dynamic environments.
- B. A flat Layer 2 network with STP is prone to broadcast storms, lacks scalability, and does not provide the advanced policy capabilities or automation required for a modern university network.
- C. A distributed autonomous AP deployment lacks centralized control, consistent policy enforcement, and the integrated wired/wireless automation needed for a large campus.
Cisco SD-Access
Cisco Software-Defined Access (SD-Access) is an intent-based networking solution that automates network provisioning, applies consistent security policies, and simplifies management for wired and wireless campus networks.
- Automates network provisioning and policy enforcement.
- Provides microsegmentation for enhanced security.
- Simplifies operations for large campus environments.
