Q19. Which protocol runs between the vSmart controllers and between the vSmart controllers and the vEdge routers, and unifies all control plane functions under a single protocol umbrella?
Explanation The protocol that runs between the vSmart controllers and between the vSmart controllers and the vEdge routers, and unifies all control plane functions under a single protocol umbrella is the Overlay Management Protocol (OMP)12. OMP is a proprietary protocol that is designed to enable the Cisco SD-WAN solution, which provides a software overlay that runs over standard network transport, including MPLS, broadband, and internet to deliver applications and services3. OMP provides the following services12: Orchestration of overlay network communication, including connectivity among network sites, service chaining, and VPN or VRF topologies Distribution of service-level routing information and related location mappings Distribution of data plane security parameters Central control and distribution of routing policy OMP is an all-encompassing information management and distribution protocol that enables the overlay network by separating services from transport. Services provided in a typical VPN setting are usually located within a VPN domain, and they are protected so that they are not visible outside the VPN. In such a traditional architecture, it is a challenge to extend VPN domains and service connectivity. OMP addresses these scalability challenges by providing an efficient way to manage service traffic based on the location of logical transport end points. This method extends the data plane and control plane separation concept from within routers to across the network2.

Q23. Which two Cisco ISE use cases typically involve the highest level of implementation complexity? (Choose two.)
Explanation Cisco ISE use cases can be classified into four categories: device management, asset visibility, software-defined segmentation, and software-defined access. Each of these use cases has a different level of implementation complexity, depending on the network size, topology, security requirements, and integration with other technologies. Among these use cases, software-defined segmentation and software-defined access typically involve the highest level of implementation complexity, because they require: A thorough understanding of the network architecture and design principles, such as hierarchical, modular, and scalable design. A comprehensive assessment of the network devices, endpoints, users, applications, and policies, and their interdependencies and interactions. A careful planning and testing of the network segmentation and access policies, using tools such as Cisco TrustSec, Cisco DNA Center, Cisco SD-Access, and Cisco ISE . A smooth and secure migration from the existing network to the software-defined network, with minimal disruption and downtime. A continuous monitoring and optimization of the network performance, security, and compliance, using tools such as Cisco Stealthwatch, Cisco Tetration, and Cisco ISE .

Q31. Which three options focus of the current digital business era? (Choose three.)
Explanation The current digital business era is characterized by the rapid growth and adoption of digital technologies that enable companies to improve their business capabilities, operational efficiencies, and customer experiences. According to various sources, such as McKinsey1 and Forbes23, some of the key focus areas of the current digital business era are: IoT scale: The Internet of Things (IoT) refers to the network of physical devices, sensors, and machines that are connected to the internet and can communicate, collect, and exchange data. The IoT scale represents the massive amount and variety of data that are generated and processed by the IoT devices, as well as the potential value and insights that can be derived from them. The IoT scale also poses new challenges and opportunities for businesses, such as enhancing customer engagement, optimizing operations, creating new products and services, and ensuring security and privacy45. Automation: Automation refers to the use of technology to perform tasks or processes that would otherwise require human intervention or effort. Automation can increase productivity, efficiency, accuracy, and consistency, as well as reduce costs, errors, and risks. Automation can also enable businesses to scale up or down their operations, respond to changing customer demands, and innovate faster. Automation can be applied to various domains and functions, such as manufacturing, marketing, customer service, finance, and human resources6 . Connectivity: Connectivity refers to the ability to access, share, and exchange information and resources across different platforms, devices, and locations. Connectivity can enhance the communication and collaboration among businesses, customers, partners, and employees, as well as enable new business models and value propositions. Connectivity can also create new customer expectations and preferences, such as personalization, convenience, and speed. Connectivity can be enabled by various technologies, such as cloud computing, mobile devices, social media, and artificial intelligence .

Q33. How would Cisco ISE handle authentication for your printer that does not have a supplicant?
Explanation Cisco ISE can handle authentication for printers that do not have a supplicant using MAB (MAC Authentication Bypass). MAB is a method of authenticating devices based on their MAC address. MAB is useful for devices that do not support 802.1X or other authentication protocols, such as printers, cameras, or IoT devices. MAB works as follows: The device sends an Ethernet frame with its MAC address as the source address. The switch sends a RADIUS Access-Request message to ISE with the MAC address as the username and password. ISE checks the MAC address against a database of known devices or an identity source sequence. If the MAC address is found and authorized, ISE sends a RADIUS Access-Accept message to the switch with the appropriate authorization profile. The switch applies the authorization profile to the device and grants it access to the network. MAB is less secure than 802.1X, as MAC addresses can be spoofed or cloned. Therefore, MAB should be used with caution and combined with other security measures, such as profiling, posture, or endpoint protection. MAB should also be restricted to specific ports or VLANs that are isolated from the rest of the network.

Q40. Which Cisco product were incorporated into Cisco ISE between ISE releases 2.0 and 2.3?
Explanation Cisco ISE incorporated Cisco ACS (Cisco Secure Access Control System) between ISE releases 2.0 and 2.3. Cisco ACS was a network access policy platform that provided authentication, authorization, and accounting (AAA) services for network devices and users. Cisco ACS was discontinued in 2017 and replaced by Cisco ISE, which offers more advanced features and capabilities for identity-based network access control. Cisco ISE provides a migration tool that allows customers to migrate their data and configurations from Cisco ACS to Cisco ISE. The migration tool supports Cisco ACS versions 5.5, 5.6, 5.7, and 5.8 and Cisco ISE versions 2.0, 2.1, 2.2, and 2.3.
