Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q422-Q427):

NEW QUESTION # 422
Which SDN architecture component is used by the application layer to communicate with the control plane layer to provide instructions about the resources required by applications?

Answer: C

Explanation:
* B (Northbound APIs):Northbound APIs allow applications to communicate with the SDN controller to express service requests and provide policy intent. The controller translates these into instructions for the underlying infrastructure.
Other options explained:
* A: Southbound APIs connect controllers to forwarding devices.
* C: Orchestration coordinates workflows across domains but doesn't directly connect applications to controllers.
* D: The SDN controller receives the northbound API calls but is not the API itself.


NEW QUESTION # 423
Drag and drop the multicast protocols from the left onto the current design situation on the right.

Answer:

Explanation:


NEW QUESTION # 424
Which two statements describe network automation and network orchestration? (Choose two.)

Answer: A,C

Explanation:
* B (Automation spans multiple vendors and services):Automation tools can handle provisioning, configuration, monitoring, and integration across heterogeneous vendor networks.
* D (Provisioning services = automation):Routine tasks like service provisioning, device onboarding, or configuration are handled by automation systems to reduce operational workload.
Other options explained:
* A: Automation can absolutely include policy enforcement if integrated properly.
* C: Orchestration governs higher-level workflows across multiple domains and uses APIs but is not limited to basic automation tasks.
* E: Orchestration coordinates complex workflows, not just single low-level tasks.


NEW QUESTION # 425
A large defense organization is planning their cloud migration journey, but they have high data sovereignty concerns, major regulation or compliance requirements, and very restrictive SLAs. Which cloud architecture model can be adopted?

Answer: E


NEW QUESTION # 426
Which MPLS TE design consideration is true?

Answer: B

Explanation:
* C: MPLS TE (Traffic Engineering) is designed to optimize IP traffic flow by considering bandwidth constraints, delay sensitivity, and administrative policy. It enables operators to steer traffic based on defined metrics rather than pure shortest-path IGP routes.
Other options:
* A: MPLS TE can coexist with LDP and still rely on IGP for link-state info; it does not replace LDP.
* B: MPLS TE by itself doesn't provide protection; it requires Fast Reroute (FRR) mechanisms like link
/node protection extensions.
* D: MPLS TE is independent of VPN topology; it can operate without requiring a full-mesh of Layer 3 VPNs.
