NEW QUESTION # 12
Which two activities should occur during an SE's demo process? (Choose two.)

• A. determining whether the customer would like to dive deeper during a follow -up
• B. asking the customer to provide network drawings or white board the environment for you
• C. identifying which capabilities require demonstration
• D. highlighting opportunities that although not currently within scope would result in lower operational costs and complexity
• E. leveraging a company such as Complete Communications to build a financial case

Answer: A,C

Explanation:
Explanation
According to the Cisco Design Zone website1, an SE's demo process should include the following activities:
Identifying which capabilities require demonstration: The SE should understand the customer's business objectives, pain points, and technical requirements, and map them to the relevant Cisco solutions and capabilities. The SE should also prioritize the most important and impactful features and benefits that address the customer's needs and challenges, and plan the demo accordingly. The SE should avoid showing irrelevant or unnecessary features that may confuse or distract the customer12.
Determining whether the customer would like to dive deeper during a follow-up: The SE should use the demo as an opportunity to engage the customer in a dialogue, solicit feedback, and gauge the customer's interest and satisfaction. The SE should also identify any gaps or questions that the customer may have, and offer to provide more information or a deeper dive during a follow-up session. The SE should also ask for the customer's permission to schedule a follow-up meeting or call, and confirm the next steps and actions13.
The other activities are not recommended or necessary during an SE's demo process, because:
Highlighting opportunities that although not currently within scope would result in lower operational costs and complexity: The SE should focus on the customer's current scope and needs, and not try to upsell or cross-sell other solutions or services that are not relevant or requested by the customer. The SE should also respect the customer's budget and timeline, and not introduce additional costs or complexity that may jeopardize the deal or the relationship1 .
Asking the customer to provide network drawings or white board the environment for you: The SE should prepare for the demo by doing the necessary research and discovery before the meeting, and not rely on the customer to provide the information or draw the network for them. The SE should also demonstrate their expertise and credibility by showing their knowledge of the customer's environment and challenges, and not ask the customer to do their work for them1 .
Leveraging a company such as Complete Communications to build a financial case: The SE should not outsource or delegate the financial analysis or justification of the solution to a third-party company, as this may undermine the SE's role and value, and create a dependency or risk for the deal. The SE should also use the Cisco tools and resources available to them, such as the Business Value Calculator, to build a financial case and show the return on investment and total cost of ownership of the solution1 .

NEW QUESTION # 13
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?

• A. OSPF
• B. VRRP
• C. BGP
• D. IKE
• E. OMP

Answer: E

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.

NEW QUESTION # 16
Which component of the SD-Access fabric is responsible for communicating with networks that are external to the fabric?

• A. border nodes
• B. control plane nodes
• C. edge nodes
• D. intermediate nodes

Answer: A

Explanation:
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 provide an 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 # 18
Which two statements regarding Cisco SD-WAN vEdge routers can mitigate DoS attacks against the infrastructure? (Choose two.)

• A. In case of direct Internet access, the only traffic allowed back is the traffic matching the state table entries on the vEdge router.
• B. By default, all incoming traffic is denied at the transport (WAN) side interfaces.
• C. The vEdge routers run on hardened Linux operating systems.
• D. Open Certificate Authority and automated enrollment feature.
• E. Only authorized controllers are allowed to communicate back to the vEdg e router after the vEdge router establishes connection with the controllers.

Answer: B,E

Explanation:
Explanation
Cisco SD-WAN vEdge routers can mitigate DoS attacks against the infrastructure by using two mechanisms:
Only authorized controllers are allowed to communicate back to the vEdge router after the vEdge router establishes connection with the controllers. This means that the vEdge router initiates a secure connection to the vSmart controller and the vBond orchestrator using DTLS or TLS, and verifies their identity using certificates. The vEdge router does not accept any incoming connections from the controllers, and only responds to the messages that match the established sessions. This prevents unauthorized or malicious traffic from reaching the vEdge router and consuming its resources12.
By default, all incoming traffic is denied at the transport (WAN) side interfaces. This means that the vEdge router applies an implicit deny-all policy to any traffic that arrives from the WAN side, unless it is explicitly allowed by a security policy. The security policy can be configured to permit only the traffic that matches certain criteria, such as source, destination, protocol, port, or application. This reduces the attack surface of the vEdge router and protects it from unwanted or harmful traffic34.

NEW QUESTION # 21
How would Cisco ISE handle authentication for your printer that does not have a supplicant?

• A. ISE would authenticate the printer using web authentication.
• B. ISE would authenticate the printer using MAC RADIUS authentication.
• C. ISE would authenticate the printer using MAB.
• D. ISE would not authenticate the printer as printers are not subject to ISE authentication.
• E. ISE would authenticate the printer using 802.1X authentication.

Answer: C

Explanation:
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.

NEW QUESTION # 26
Which two statements are true regarding Cisco ISE? (Choose two.)

• A. An ISE deployment requires only a Cisco ISE network access control appliance.
• B. The major business outcomes of ISE are enhanced user experience and secure VLAN segmentation.
• C. ISE can provide data about when a specific device connected to the network.
• D. ISE plays a critical role in SD-Access.
• E. Without integration with any other product, ISE can track the actual physical location of a wireless endpoint as it moves.

Answer: C,D

Explanation:
Cisco ISE is a policy decision point that enables enterprises to ensure compliance, enhance infrastructure security, and streamline service operations. Some features and benefits of Cisco ISE include1:
* Zero trust across the network: ISE allows only trusted users and devices access to resources on your network. It also uses intel to automatically identify, classify and profile devices.
* Policy and lifecycle management: ISE simplifies the delivery of consistent, highly secure access control across wired, wireless, and VPN connections. It also allows users to add and manage their own devices through self-service portals.
* Remote management and deployment: ISE supports cloud-based deployment and management, as well as integration with other Cisco products and third-party solutions.
* Site survivability: ISE provides local authentication and authorization services for remote sites, even when the connection to the central ISE server is lost.
* Visibility of all devices and their users: ISE can provide data about when a specific device connected to the network, what type of device it is, who is using it, what applications are running on it, and where it is located.
Among these features, two statements are true regarding Cisco ISE:
* ISE plays a critical role in SD-Access: SD-Access is a network architecture that uses software-defined networking (SDN) principles to create a secure, scalable, and consistent network fabric. ISE is the policy engine that defines and enforces the network segmentation and access policies for SD-Access2.
* ISE can provide data about when a specific device connected to the network: ISE uses a number of probes to collect attributes for all endpoints on the network, and pass them to the Profiler analyzer, where the known endpoints are classified according to their associated policies and identity groups. ISE can also provide historical data about the endpoint connections, such as the time, duration, location, and user of the connection3.
The other three statements are false regarding Cisco ISE:
* The major business outcomes of ISE are enhanced user experience and secure VLAN segmentation: ISE provides more than just user experience and VLAN segmentation. It also delivers business outcomes such as improved network performance, reduced operational costs, increased security, and simplified compliance4.
* An ISE deployment requires only a Cisco ISE network access control appliance: ISE can be deployed on different platforms, such as physical appliances, virtual machines, or cloud services. An ISE deployment also requires other components, such as network devices, endpoints, and external identity sources5.
* Without integration with any other product, ISE can track the actual physical location of a wireless endpoint as it moves: ISE can provide the location information of an endpoint based on the network device that it is connected to, such as the switch port or the wireless access point. However, to track the actual physical location of a wireless endpoint as it moves, ISE needs to integrate with other products, such as Cisco DNA Center, Cisco Connected Mobile Experiences (CMX), or Cisco Wireless LAN Controller (WLC)6.
