Device Sensor is a feature that enables Cisco devices to collect and report information about the endpoints connected to them. This information can be used by ISE to identify and classify the endpoints, and apply appropriate policies based on their attributes. Device Sensor can collect information from various sources, such as DHCP, CDP, LLDP, and HTTP User-Agent. Among the options given, only DHCP and CDP are valid sources of information for Device Sensor. References := : Cisco Identity Services Engine Administrator Guide, Release 2.7 - Device Sensor [Cisco Identity Services Engine]- Cisco (https://learningnetworkstore.cisco.com/c/en/us/td/docs/security/ise/2-7/admin_guide/b_ise_admin_guide_27/b_ise_admin_guide_27_chapter_010100.html)

According to the Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers document1, the three Cisco recommendations on “How to Win” are:

• Explain support for 3rd party network devices: Cisco ISE can integrate with more than 60 third-party solutions that span across security and network portfolios. This enablesCisco ISE to leverage the information and capabilities of these solutions to enhance the identity and access management, network visibility and segmentation, threat detection and response, and policy enforcement of the network. By explaining this support, the customer can see the value and flexibility of Cisco ISE in their existing or heterogeneous network environment2.
• Explain architectural advantage of holistic Cisco solution: Cisco ISE is part of the Cisco Digital Network Architecture (DNA), which is a comprehensive and open platform that provides end-to-end network automation, assurance, security, and analytics. By explaining the architectural advantage of the holistic Cisco solution, the customer can see how Cisco ISE works seamlessly with other Cisco DNA components, such as Cisco DNA Center, Cisco SD-Access, Cisco SD-WAN, Cisco TrustSec, and Cisco Stealthwatch, to deliver a unified and consistent network experience across wired, wireless, and cloud domains3.
• Talk about Cisco’s focus on Security and integration with StealthWatch, Sourcefire, WSA, vulnerability scanner to make smarter policy decisions: Cisco ISE is a core component of the Cisco security portfolio, which provides comprehensive and integrated security solutions for the network. By talking about Cisco’s focus on security and integration with other security products, such as StealthWatch, Sourcefire, WSA, and vulnerability scanner, the customer can see how Cisco ISE can provide enhanced visibility, threat detection, and policy enforcement for the network. For example, Cisco ISE can use the data from StealthWatch to identify anomalous or malicious behavior of the endpoints and apply appropriate network access policies based on the threat level4.

The other options, show case Cisco portfolio or ISE feature set during PoC and demonstrate complex policy flows, rather show case Wizards and enhanced context visibility, are not Cisco recommendations on “How to Win”. Showing case Cisco portfolio or ISE feature set during PoC is a general best practice, but not a specific recommendation for winning the customer. Demonstrating complex policy flows, rather than showing case Wizards and enhanced context visibility, is a counterproductive approach, as it can confuse or overwhelm the customer with technical details, rather than highlighting the benefits and simplicity of Cisco ISE. References := : 2: Cisco Identity Services Engine Administrator Guide, Release 2.7 - ISE Security Ecosystem Integration Guides [Cisco Identity Services Engine] - Cisco2, 1: Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers1, 3: Cisco Identity Services Engine - Cisco3, 4: Cisco Identity Services Engine Administrator Guide, Release 2.7 - Stealthwatch Integration [Cisco Identity Services Engine] - Cisco4

 ISE automation BYOD flow is a process that allows users to self-enroll their devices to the network without requiring IT intervention. The process consists of three main functions: certificate enrollment, device registration, and supplicant provisioning.

• Certificate enrollment is the function that allows users to obtain a digital certificate from a certificate authority (CA) for their devices. This certificate is used to authenticate the device to the network and provide secure communication. ISE supports different CA options, such as Microsoft CA, Cisco ISE CA, or third-party CA .
• Device registration is the function that allows users to register their devices to the network and associate them with their identity. This enables ISE to apply policies based on the device type, ownership, and posture. ISE supports different device registration methods, such as portal-based, API-based, or bulk import .
• Supplicant provisioning is the function that allows users to install and configure a network access client (supplicant) on their devices. This client is used to connect to the network using the appropriate protocols and settings. ISE supports different supplicant provisioning methods, such as native supplicant, Cisco Network Setup Assistant (NSA), or Cisco AnyConnect Secure Mobility Client (AnyConnect) .

 A WAN design is a plan for how to connect multiple sites or locations over a wide area network (WAN). A WAN design can have various benefits, depending on the goals and requirements of the organization. Two of the possible benefits from a WAN design are:

• Ensure remote site uptime: A WAN design can help to ensure that remote sites or branches have reliable and consistent connectivity to the central site or the cloud. This can improve the availability and performance of critical applications and services, such as voice, video, collaboration, and data backup. A WAN design can also provide redundancy and resiliency in case of network failures or disasters, by using multiple WAN links, backup routes, or failover mechanisms. For example, SD-WAN is a WAN design that uses software to dynamically route traffic over the best available WAN link, based on the network conditions and the application requirements1.
• Prioritize and secure with granular control: A WAN design can also help to prioritize and secure the traffic and applications that flow over the WAN. This can enhance the quality of service (QoS) and the security of the network. A WAN design can use various techniques, such as traffic shaping, policy-based routing, encryption, firewall, or VPN, to classify, prioritize, and secure the WAN traffic according to the business needs and the security policies. For example, TrustSec is a WAN design that uses software-defined segmentation to enforce granular access policies based on the identity and context of users, devices, and applications2.

The other options, provide lower quality service to guest users, reduce cost and increase operational complexity, and lower circuit bandwidth requirements, are not benefits from a WAN design. Providing lower quality service to guest users is not a desirable outcome, as it can affect the user experience and the reputation of the organization. Reducing cost and increasing operational complexity is a trade-off that may not be worth it, as it can create more challenges and risks for the network management and maintenance. Lowering circuit bandwidth requirements is not a benefit in itself, but a means to achieve other benefits, such as reducing cost or improving performance. A WAN design should aim to optimize the bandwidth utilization and allocation, rather than simply lowering it. References := : 1: Cisco SD-WAN Solution Design Guide (CVD) - Cisco1, 2: Cisco TrustSec Solution Overview - Cisco

Some of the statements that are true regarding Cisco SD-WAN license tiers are:

• With Pro license, control and data policies are supported2. This license tier enables network operators to define and enforce policies for traffic shaping, quality of service (QoS), application optimization, and security2.
• With Plus license, split-tunnel is supported3. This license tier enables network operators to use split-tunneling technology to route traffic through different paths based on application or user preferences3.
• With Enterprise license, vAnalytics is included4. This license tier enables network operators to use vAnalytics feature to collect and analyze data from various sources such as endpoints, applications, devices, networks, and cloud services4.

SD-WAN is a software-defined approach to managing the WAN that offers several capabilities, such as:

• The separation of management plane, control plane and data plane to enable horizontal scaling. This means that the SD-WAN solution can decouple the network functions from the underlying hardware and distribute them across different layers and locations. This allows for greater flexibility, scalability, and resilience of the network12
• Cloud hosted or on-premise fully redundant management and control plane functions. This means that the SD-WAN solution can provide centralized and cloud-based management and control of the network, as well as the option to deploy them on-premise for more control and security. This enables the SD-WAN solution to offer consistent policies, visibility, and analytics across the network, as well as the ability to automate network operations and orchestration13

The other options are not SD-WAN solution capabilities, but rather features or benefits of specific SD-WAN solutions, such as:

• Trust roll branch turn up for easy provisioning and new installations. This is a feature of Cisco Catalyst SD-WAN, which enables zero-touch provisioning and automated configuration of branch devices, as well as the ability to trust the identity and security posture of the devices3
• Ability to provide and integrate security with complementary products and applications. This is a benefit of Cisco Catalyst SD-WAN, which offers integrated security capabilities, such as full-stack multilayer security, cloud-delivered security, and SASE-enabled architecture. This enables the SD-WAN solution to provide real-time threat protection and compliance across the network3

 Fabric overlay concepts are related to the creation of a virtual network topology on top of a physical network infrastructure. The overlay network is usually designed to provide services or features that are not directly supported by the underlay network, such as network segmentation, mobility, or security. Some of the fabric overlay concepts are:

• An overlay is a logical topology: An overlay network is a network that is built on top of another network using software or hardware devices that encapsulate and decapsulate packets. The overlay network creates a logical topology that is independent of the physical topology of the underlay network. The overlay network can span multiple Layer 2 or Layer 3 domains and provide end-to-end connectivity for the overlay endpoints. An example of an overlay network is a VPN that connects remote sites over the Internet.
• GRE is a type of overlay: Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets of one protocol type within another protocol type. GRE is used to create tunnels between devices that can carry different types of traffic, such as IP, IPv6, MPLS, or Ethernet. GRE is a type of overlay network that can be used to extend Layer 2 or Layer 3 connectivity across different networks or to provide a secure and private communication channel. An example of a GRE overlay network is a DMVPN that uses GRE tunnels to connect branch offices to a central hub over the Internet.
• An overlay uses alternate forwarding attributes: An overlay network uses different attributes or identifiers to forward packets than the underlay network. The overlay network adds specific headers or tags to the packets that contain information about the overlay endpoints, such as their logical addresses, group memberships, or policies. The overlay devices use these attributes to forward packets based on the overlay topology and services, rather than the underlay topology and protocols. The underlay devices are unaware of the overlay attributes and forward packets based on the underlay headers. An example of an overlay network that uses alternate forwarding attributes is a VXLAN network that uses VNIs to segment traffic and provide Layer 2 connectivity over a Layer 3 network.

The other options, Intermediate System to Intermediate System (IS-IS), a virtual Local Area Network (VLAN), and a link state routing protocol like OSPF, are not fabric overlay concepts. IS-IS and OSPF are routing protocols that are used to exchange routing information and build the routing table of the underlay network. A VLAN is a Layer 2 segmentation technique that divides a physical network into logical subnets based on the switch port membership. A VLAN is not an overlay network, but it can be part of the underlay network or the overlay network, depending on the design. References := : Fabric Technologies and Overlays - Cisco Learning Network1, What Is a Network Fabric? - Cisco2
