NEW QUESTION # 125
Which protocol does an SD-Access wireless Access Point use for its fabric data plane?
- A. LISP
- B. MPLS
- C. CAPWAP
- D. GRE
- E. VXLAN
Answer: E
Explanation:
In Cisco SD-Access architecture, fabric-enabled wireless APs connect to the network usingCAPWAPfor control, but their data plane is integrated into thefabric overlayusingVXLAN (Virtual Extensible LAN).
* VXLANis the data plane encapsulation used between fabric nodes, including wireless APs that are part of the SD-Access fabric.
* WhileCAPWAP (E)remains in use for management and control communication between the AP and wireless LAN controller (WLC), actual user traffic is encapsulated in VXLAN for fabric forwarding.
This separation of control and data plane ensures seamless mobility, segmentation, and policy enforcement within the SD-Access fabric.

- A. Aggregate links Layer 2 link aggregation.
- B. Filter IGMP joins on an over -utilized link.

NEW QUESTION # 128
An enterprise network has two core routers that connect to 200 distribution routers and uses full-mesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?
- A. Implement eBGP between the core and distribution routers
- B. Increase the memory on the distribution routers
- C. Increase bandwidth between the core routers
- D. Increase the memory on the core routers
- E. Implement route reflectors on the two core routers
Answer: E
Explanation:
In a full-mesh iBGP design, every router must establish and maintain a BGP session with every other router.
As the number of routers increases, the number of BGP sessions and the amount of BGP processing increases exponentially. This leads to high CPU utilization, especially in devices with limited processing capabilities, such as distribution routers.
Themost cost-effectiveandscalablesolution in this scenario is toimplement route reflectors (RRs)on the two core routers. Route reflectors significantly reduce the number of iBGP peerings required, eliminating the full mesh requirement by allowing the distribution routers (RR clients) to establish a single iBGP session with the route reflector. The route reflector handles route advertisement to other RR clients, thereby reducing overhead on the distribution routers.
This solution adheres to CCDE v3.1 design principles for:
* Optimizing control plane scalability
* Reducing unnecessary CPU load from control protocols
* Ensuring a maintainable and scalable enterprise BGP deployment
Why the other options are incorrect:
* BandD(Increasing memory): Addresses only hardware capacity without solving the root cause (BGP scaling issue).
* C(Using eBGP): Misaligned with enterprise internal network design; eBGP adds complexity in route policy and administrative boundaries.
* E(Increasing bandwidth): Bandwidth does not alleviate CPU overhead caused by BGP processing.
Implementing route reflectors aligns with both scalability and cost-efficiency goals as prescribed in the CCDE v3.1 methodology.
