Which get-config replay verifies that the model set was designed correctly?
Answer: D
NEW QUESTION # 182
Which two functions does the control plane node provide in a Cisco SD-Access architecture? (Choose two.)
Answer: A,B
Explanation:
The Cisco SD-Access control-plane node provides the host tracking database and map-server function. SD- Access uses LISP-based control-plane behavior to separate endpoint identity from endpoint location. Fabric edge nodes register endpoints with the control-plane node, and the control-plane node maintains the endpoint- to-location database. When a fabric node needs to forward traffic to an endpoint, it queries the control-plane node so the destination endpoint can be resolved to the correct fabric location. In LISP terminology, this maps to the map-server and map-resolver role, while the SD-Access design discussion often refers to the endpoint database or host tracking database. The control-plane node does not enforce policy mapping by itself; policy is integrated with Cisco ISE and applied through scalable group policy in the fabric. It also does not function as a proxy ETR in this option set. Endpoint registration is initiated by the edge nodes, which detect local endpoints and inform the control plane. Therefore, host tracking database and map server are the correct functions. Reference topics: SD-Access control plane, LISP map server, host tracking database, EID-to- RLOC mapping.
NEW QUESTION # 183
An enterprise customer has these requirements:
* end-to-end QoS for the business-critical applications and VoIP services based on CoS marking.
* flexibility to offer services such as IPv6 and multicast without any reliance on the service provider.
* support for full-mesh connectivity at Layer 2.
Which WAN connectivity option meets these requirements?
Answer: C
Explanation:
The requirements point to a Layer 2 multipoint WAN service. VPLS provides an emulated Ethernet LAN across a provider network, allowing multiple sites to appear as if they are connected to the same Layer 2 domain. This supports full-mesh Layer 2 connectivity and preserves customer control over higher-layer services such as IPv6, multicast, routing protocols, and QoS markings. Because the provider delivers an Ethernet multipoint service, the enterprise can retain protocol independence rather than depending on the service provider to participate in IPv6 routing or multicast routing. CoS marking is also a Layer 2 QoS mechanism, so a Layer 2 VPN service is better aligned to the stated QoS requirement. VPWS is point-to-point rather than full-mesh multipoint, so it does not meet the topology requirement by itself. MPLS Layer 3 VPN is a provider-routed service and does not give the customer full Layer 2 mesh behavior. DMVPN is an overlay routed VPN and does not provide a native Layer 2 full-mesh service. Therefore, VPLS is the correct WAN connectivity option.
