Which element of the Cisco SD-WAN architecture facilitates the functions of controller discovery and NAT traversal?
- A. vSmart controller
- B. vEdge
- C. vManage
- D. vBond orchestrator
正解：D
解説：
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.

- B. Showcasing the entire ISE feature set
- C. Downplaying the value of pxGrid as compared to RESTful APIs
- D. Discussing the importance of custom profiling

正解：A、B
解説：
Explanation
Cisco ISE is a comprehensive solution that enables enterprises to enforce consistent and secure access policies across wired, wireless, and VPN connections. It also provides visibility, control, and automation for the network devices, endpoints, users, and applications. To sell Cisco ISE effectively, it is important to highlight the benefits and features of the solution that address the customer's pain points and needs. Among the options given, two options help you sell Cisco ISE:
Showcasing the entire ISE feature set: ISE has a rich and diverse feature set that covers various use cases, such as device management, asset visibility, software-defined segmentation, software-defined access, guest and wireless access, BYOD, posture assessment, threat detection and response, and more1.
By showcasing the entire ISE feature set, you can demonstrate the value proposition and differentiation of ISE from other solutions, and how it can help the customer achieve their business and technical goals.
Explaining ISE support for 3rd party network devices: ISE is not limited to Cisco networks only. It can also support 3rd party network devices that comply with the standard protocols and interfaces, such as RADIUS, SNMP, TACACS+, 802.1X, MAB, CoA, and EAP2. By explaining ISE support for 3rd party network devices, you can show the customer that ISE is a flexible and interoperable solution that can work with their existing network infrastructure, and that they do not need to replace their non-Cisco devices to deploy ISE.
The other three options are not helpful for selling Cisco ISE:
Referring to TrustSec as being only supported on Cisco networks: TrustSec is a Cisco technology that enables software-defined segmentation based on security group tags (SGTs) and security group access control lists (SGACLs)3. TrustSec is not only supported on Cisco networks, but also on 3rd party network devices that can integrate with ISE through pxGrid, which is a platform for sharing contextual information across multiple security products4. By referring to TrustSec as being only supported on Cisco networks, you can create a false impression that ISE is a proprietary and closed solution that requires a complete Cisco network overhaul, which can discourage the customer from adopting ISE.
Discussing the importance of custom profiling: Profiling is a feature of ISE that allows it to identify and classify the endpoints on the network based on their attributes, such as MAC address, IP address, device type, operating system, etc.5. Custom profiling is the ability to create custom profiles and policies for the endpoints that are not recognized by the default ISE profiles. While custom profiling is an important feature of ISE, it is not a key selling point, because it is a complex and time-consuming process that requires a deep understanding of the endpoint attributes and behaviors, and it may not be relevant or applicable for all customers. By discussing the importance of custom profiling, you can confuse or overwhelm the customer with technical details that are not essential for their use case, and divert their attention from the core benefits and features of ISE.
Downplaying the value of pxGrid as compared to RESTful APIs: pxGrid is a platform that enables ISE to share contextual information, such as identity, location, posture, device type, etc., with other security products, such as firewalls, SIEMs, threat detection systems, etc.4. RESTful APIs are a standard way of communicating with web services, such as ISE, using HTTP methods, such as GET, POST, PUT, DELETE, etc... Both pxGrid and RESTful APIs are valuable for ISE, because they provide different capabilities and benefits. pxGrid allows ISE to exchange real-time and bidirectional information with other security products, and to enforce consistent policies across the network4. RESTful APIs allow ISE to be integrated with external applications and systems, such as portals, dashboards, workflows, etc., and to automate and customize the network operations. By downplaying the value of pxGrid as compared to RESTful APIs, you can misrepresent the functionality and potential of ISE, and miss the opportunity to showcase how ISE can enhance the security and efficiency of the network.

質問 # 38
What are the three foundational elements required for the new operational paradigm? (Choose three.)
- A. multiple technologies at multiple OSI layers
- B. policy-based automated provisioning of network
- C. assurance
- D. centralization
- E. fabric
- F. application QoS
正解：B、C、E
解説：
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.

Explanation
A cloud-based SD-WAN deployment is a model of delivering SD-WAN services from the cloud, rather than from on-premises hardware or software appliances. A cloud-based SD-WAN deployment has several benefits, such as:
Instant scale: A cloud-based SD-WAN deployment can scale up or down the network resources and bandwidth on demand, without requiring additional hardware or manual configuration. This enables the network to adapt to the changing traffic patterns and user demands, while optimizing the network performance and efficiency12.
Reduced costs: A cloud-based SD-WAN deployment can lower the capital and operational expenses of the network, by eliminating the need for expensive and complex WAN infrastructure, such as MPLS circuits, routers, firewalls, and WAN optimization devices. A cloud-based SD-WAN deployment can also leverage the economies of scale and the pay-as-you-go model of the cloud, which can reduce the network costs per megabit12.
Simplified management: A cloud-based SD-WAN deployment can simplify the network management and operation, by providing a centralized and unified dashboard that can monitor, configure, and troubleshoot the network across multiple sites and regions. A cloud-based SD-WAN deployment can also automate the network provisioning, orchestration, and optimization, by applying intelligent policies and analytics based on the business intent and network conditions12.
Enhanced security: A cloud-based SD-WAN deployment can enhance the network security and compliance, by providing built-in and integrated security features, such as encryption, firewall, VPN, IPS, and antivirus. A cloud-based SD-WAN deployment can also leverage the cloud security services, such as SASE, to provide secure and direct access to the cloud applications and platforms, without compromising the network performance and user experience123.
Improved cloud readiness: A cloud-based SD-WAN deployment can improve the cloud readiness and agility of the network, by enabling seamless and optimized connectivity to the public cloud, SaaS, and cloud interconnect providers. A cloud-based SD-WAN deployment can also support the multicloud and hybrid-cloud strategies, by allowing the network to operate as a cloud-native WAN overlay, using software-defined automation and orchestration tools123.
