NEW QUESTION # 10
Which two statements describes Cisco SD-Access? (Choose two.)

• A. a collection of tools and applications that are a combination of loose and tight couping
• B. programmable overlays enabling network virtualization across the campus
• C. an automated encryption/decryption engine for highly secured transport requirements
• D. an overlay for the wired infrastructure in which traffic is tunneled via a GRE tunnel to a mobility controller for policy and application visibility
• E. software-defined segmentation and policy enforcement based on user identity and group membership

Answer: B,E

Explanation:
Explanation
Cisco SD-Access is a solution within Cisco DNA, which is built on intent-based networking principles. Cisco SD-Access provides visibility-based, automated end-to-end segmentation to separate user, device, and application traffic without redesigning the underlying physical network1. Cisco SD-Access also enables programmable overlays that allow network virtualization across the campus, branch, data center, and cloud2. Cisco SD-Access has two main components: the fabric and the policy3.
The fabric is the network overlay that consists of interconnected nodes that provide a consistent and scalable way of delivering network services and functions. The fabric nodes are classified into four types: edge nodes, border nodes, control plane nodes, and intermediate nodes. The edge nodes are the access switches or wireless controllers that connect to the end devices. The border nodes are the routers or switches that connect the fabric to external networks, such as the Internet, WAN, or data center. The control plane nodes are the routers or switches that maintain the mapping between the endpoint identifiers and the network locators. The intermediate nodes are the routers or switches that provide transit services within the fabric3.
The policy is the network configuration that defines the network behavior and outcomes, based on the business intent and requirements. The policy is composed of three elements: the endpoint groups, the contracts, and the virtual networks. The endpoint groups are the logical containers that group the endpoints based on their attributes, such as user identity, device type, or application. The contracts are the rules that specify the allowed interactions between the endpoint groups, such as the protocols, ports, and quality of service. The virtual networks are the logical partitions that isolate the endpoint groups and contracts from each other, based on the network scope and security3.
Cisco SD-Access addresses the following challenges and benefits:
It simplifies the network design and management, as it reduces the complexity and variability of the network elements and interfaces.
It enhances the network security and compliance, as it enforces granular and dynamic policies based on the endpoint identity and context, rather than the network topology and IP addresses.
It improves the network performance and user experience, as it optimizes the network path, load balancing, and traffic engineering based on the network conditions and application requirements.
It enables the network agility and scalability, as it supports the rapid deployment and integration of new devices, applications, and services, without affecting the existing network operations.

NEW QUESTION # 18
How would Cisco ISE handle authentication for your printer that does not have a supplicant?

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

Answer: B

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 # 20
Which two options are primary functions of Cisco ISE? (Choose two.)

• A. enabling WAN deployment over any type of connection
• B. enforcing endpoint compliance with network security policies
• C. automatically enabling, disabling, or reducing allocated power to certain devices
• D. allocating resources
• E. providing VPN access for any type of device
• F. providing information about every device that touches the network

Answer: B,F

Explanation:
Explanation
Cisco ISE is a security policy management platform that provides secure access to network resources. Cisco ISE functions as a policy decision point and enables enterprises to ensure compliance, enhance infrastructure security, and streamline service operations1. Two of the primary functions of Cisco ISE are:
Enforcing endpoint compliance with network security policies: Cisco ISE can assess the posture of all endpoints that access the network, including 802.1X environments, and enforce the appropriate policies based on the device type, identity, location, and other attributes. Cisco ISE can also provide comprehensive client provisioning measures to ensure that the endpoints are compliant with the network security policies before granting them access. Cisco ISE can also quarantine or remediate non-compliant endpoints to prevent potential threats or vulnerabilities12.
Providing information about every device that touches the network: Cisco ISE can gather real-time contextual information from networks, users, and devices, and use that information to make governance decisions and apply policies. Cisco ISE can also discover, profile, and monitor the endpoint devices on the network, and classify them according to their associated policies and identity groups. Cisco ISE can also leverage the pxGrid framework to share the contextual information with other security tools and platforms, and enhance the network visibility and security13.
The other options are not primary functions of Cisco ISE, because:
Allocating resources: Cisco ISE does not allocate resources to the endpoints or the network devices. Cisco ISE can assign services or access levels based on the policies, but not resources such as bandwidth, memory, or CPU1.
Enabling WAN deployment over any type of connection: Cisco ISE does not enable WAN deployment over any type of connection. Cisco ISE can support VPN access for remote endpoints, but not WAN deployment for the network infrastructure1.
Automatically enabling, disabling, or reducing allocated power to certain devices: Cisco ISE does not automatically enable, disable, or reduce allocated power to certain devices. Cisco ISE can control the access and authorization of the devices, but not their power consumption or management1.
Providing VPN access for any type of device: Cisco ISE does not provide VPN access for any type of device. Cisco ISE can authenticate and authorize the VPN access for the endpoints, but not provide the VPN service or connection itself. Cisco ISE relies on other network devices, such as VPN gateways or routers, to provide the VPN access1.

NEW QUESTION # 21
What should you do if you are looking at a strategic win with a customer and the customer wants to examine Cisco ISE for longer than a few weeks?

• A. Provide them with a downloadable POV kit.
• B. Set them up with a dCloud account.
• C. Set them up with an account on a Cisco UCS server that hosts ISE.
• D. Give them some of our flash files that can be played on any browser.
• E. Point them to our dCloud demo library.
• F. Give them our ISE YouTube videos.

Answer: A

Explanation:
If you are looking at a strategic win with a customer and the customer wants to examine Cisco ISE for longer than a few weeks, you should provide them with a downloadable POV kit. A POV kit is a proof of value kit that contains a pre-configured virtual machine of Cisco ISE with licenses, sample data, and documentation. A POV kit allows the customer to quickly and easily deploy and test Cisco ISE in their own environment, without requiring any hardware or installation. A POV kit can help the customer to evaluate the features and benefits of Cisco ISE,such as identity-based access control, device profiling, posture assessment, guest management, and threat mitigation12.
The other options are not suitable for a customer who wants to examine Cisco ISE for longer than a few weeks. Pointing them to our dCloud demo library, giving them our ISE YouTube videos, or giving them some of our flash files that can be played on any browser are good ways to introduce Cisco ISE to the customer, but they do not provide a hands-on experience or a realistic scenario of how Cisco ISE works in their network.
Setting them up with a dCloud account or an account on a Cisco UCS server that hosts ISE are also possible ways to provide a demo or a trial of Cisco ISE, but they may have limitations on the duration, availability, scalability, or customization of the environment. A POV kit gives the customer more flexibility and control over their evaluation of Cisco ISE.
