CCDE: Cisco Certified Design Expert (Practical) — Question 217

SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based underlay transport network. Which two statements describe SD-WAN solutions? (Choose two.)

Answer options

• A. Control and data forwarding planes are kept separate.
• B. Solutions allow for variations of commodity and specialized switching hardware.
• C. SD-WAN networks are inherently protected against slow performance.
• D. Solutions include centralized orchestration, control, and zero-touch provisioning.
• E. Improved operational efficiencies result in cost savings.

Correct answer: A, D

Explanation

Option A is correct because SD-WAN architectures separate control and data planes, enhancing performance and security. Option D is also correct as SD-WAN solutions typically include centralized orchestration and zero-touch provisioning for easier management. Options B, C, and E are misleading; while SD-WAN may utilize various hardware, it does not inherently protect against slow performance, and cost savings are a benefit but not a defining characteristic.
