Which element of the Cisco SD-WAN architecture facilitates the functions of controller discovery and NAT traversal?
- A. vBond orchestrator
- B. vManage
- C. vSmart controller
- D. vEdge
Answer: A
Explanation:
Explanation
The vBond orchestrator is an SD-WAN router responsible for authenticating and orchestrating connectivity between the vSmart controllers and SD-WAN routers. It is the sole device in the network that requires a public IP address for all SD-WAN devices to connect to it. The vBond orchestrator has three major functions:
Controller discovery: The vBond orchestrator acts as the initial point of contact for all SD-WAN components that join the network. It authenticates the devices using pre-installed credentials and assigns them to a vSmart controller. The vBond orchestrator also provides the IP addresses of the vSmart controllers and the vManage NMS to the SD-WAN routers.
NAT traversal: The vBond orchestrator facilitates the establishment of secure DTLS or TLS tunnels between the SD-WAN components that are behind NAT devices. The vBond orchestrator acts as a rendezvous point for the NATed devices and helps them exchange their public IP addresses and port numbers. The vBond orchestrator also performs NAT keepalive and hole punching to maintain the NAT bindings and prevent the NAT devices from timing out the sessions.
Certificate management: The vBond orchestrator acts as the certificate authority (CA) for the SD-WAN network. It generates and signs the certificates for the SD-WAN components and distributes them to the devices. The certificates are used to authenticate the devices and encrypt the control and data plane traffic.

Which node enables Cisco ISE to share contextual information on a device with Cisco Stealth watch?
- A. Policy Administration Node
- B. Inline Posture Node
- C. pXGrid Controller
- D. Monitoring and Troubleshooting Node
Answer: C
Explanation:
Explanation
The node that enables Cisco ISE to share contextual information on a device with Cisco Stealthwatch is the pXGrid Controller. The pXGrid Controller is a component of the ISE Policy Service Node (PSN) that facilitates the exchange of contextual data between ISE and other security products, such as Stealthwatch, via the Platform Exchange Grid (pxGrid) protocol. The pXGrid Controller acts as a broker that registers, authenticates, and authorizes pxGrid clients, and allows them to publish and subscribe to topics of interest. For example, Stealthwatch can subscribe to the Session Directory topic to obtain user and device information from ISE, and use it to enrich the network flow data and provide better visibility and security analytics.
Stealthwatch can also publish topics, such as Rapid Threat Containment (RTC), to allow ISE to take mitigation actions on compromised endpoints, such as quarantine or re-authentication. References:

NEW QUESTION # 26
Which component of the SD-Access fabric is responsible for communicating with networks that are external to the fabric?
- A. control plane nodes
- B. intermediate nodes
- C. edge nodes
- D. border nodes
Answer: D
Explanation:
= Border nodes are the component of the SD-Access fabric that is responsible for communicating with networks that are external to the fabric. Border nodes serve as the gateway between the fabric domain and the network outside of the fabric. Border nodes are responsible for network virtualization inter-working and SGT propagation from the fabric to the rest of the network1. Border nodes also perform LISP Proxy Tunnel Router (PxTR) functions, which convert policy and reachability information, such as SGT and VRF information, from one domain to another2. Border nodes can connect to internal networks, such as data center or WAN, or external networks, such as internet or cloud3.
Edge nodes, control plane nodes, and intermediate nodes are not responsible for communicating with networks that are external to the fabric. Edge nodes are the access-layer switches where all of the endpoints reside. Edge nodes detect clients and register them with the control plane nodes. Edge nodes also providean anycast L3 gateway for the connected endpoints and perform encapsulation and de-encapsulation of data traffic4. Control plane nodes are the devices that run a host tracking database to map location information. Control plane nodes receive endpoint ID map registrations from edge and/or border nodes and resolve lookup requests from edge and/or border nodes to locate destination endpoint IDs5. Intermediate nodes are the devices that provide underlay connectivity between edge nodes and border nodes. Intermediate nodes do not participate in the fabric overlay and do not have any fabric roles6.

NEW QUESTION # 31
What are the three foundational elements required for the new operational paradigm? (Choose three.)
- A. centralization
- B. policy-based automated provisioning of network
- C. multiple technologies at multiple OSI layers
- D. assurance
- E. fabric
- F. application QoS
Answer: B,D,E
Explanation:
Explanation
The new operational paradigm is a way of designing, deploying, and managing networks that leverages the power of intent-based networking. Intent-based networking is a network architecture that aligns the network with the business goals and policies, and uses artificial intelligence and automation to translate the intent into network configurations and actions. The new operational paradigm requires three foundational elements:
Fabric: A fabric is a network topology that consists of interconnected nodes that provide a consistent and scalable way of delivering network services and functions. A fabric can span across multiple domains, such as campus, branch, data center, and cloud, and can support multiple protocols, such as IP, Ethernet, MPLS, and VXLAN. A fabric enables the network to operate as a single entity, rather than a collection of disparate devices and links. A fabric also simplifies the network design and management, as it reduces the complexity and variability of the network elements and interfaces.
Assurance: Assurance is the process of continuously monitoring, verifying, and optimizing the network performance and behavior, based on the defined intent and policies. Assurance uses telemetry, analytics, and machine learning to collect and process data from the network devices and applications, and to provide insights and recommendations for network optimization and troubleshooting. Assurance also enables the network to self-heal and self-optimize, by applying corrective actions and adjustments to the network configurations and policies, based on the feedback loop from the data and analytics.
Policy-based automated provisioning of network: Policy-based automated provisioning of network is the process of applying the intent and policies to the network devices and services, using automation and orchestration tools. Policy-based automated provisioning of network abstracts the network complexity and heterogeneity, and allows the network operators to define the network requirements and outcomes in a high-level and declarative way, rather than specifying the low-level and imperative commands and parameters. Policy-based automated provisioning of network also enables the network to be agile and adaptive, as it can dynamically adjust the network configurations and policies, based on the changing network conditions and business needs.
