Cisco 500-470 Exam With Confidence Using Practice Dumps

A centralized SD-Access design is where a single fabric domain spans across the main site and all branch sites over the WAN. This design has some challenges, such as:

• Since the traffic is encapsulated in VXLAN headers, SD-WAN features such as application-aware routing, QoS, and security policies cannot be applied to the traffic based on the original IP headers. This means that the SD-WAN controller cannot optimize or route the traffic based on the application or user identity. The traffic is treated as a single class of service across the WAN.
• The centralized design also introduces a single point of failure and a potential bottleneck at the main site, where the border nodes and the control plane nodes are located. If the main site goes down or the WAN link fails, the branch sites will lose connectivity to the fabric domain and the external networks.
• The centralized design also requires a high bandwidth and low latency WAN connection between the main site and the branch sites, which may not be feasible or cost-effective for some scenarios.

Cisco ISE configuration capabilities include the following features:

• ISE Deployment Assistant (IDA) is a built-in application designed to accelerate the deployment of Cisco Identity Service Engine (ISE). IDA guides the user through the initial setup, configuration, and verification of ISE with a step-by-step wizard. IDA also provides best practices and recommendations for common deployment scenarios, such as wireless, wired, VPN, guest, and BYOD1.
• Cisco ISE includes wireless setup wizard and visibility wizard. The wireless setup wizard simplifies the configuration of ISE for wireless access by automating the tasks of adding network devices, creating authorization profiles, and applying policies. The visibility wizard helps the user to enable device profiling and posture services, and to view the endpoint information and compliance status on the ISE dashboard2.
• ISE wizards and per-canned configurations ease ISE roll-out significantly. ISE wizards are interactive tools that assist the user in configuring various features and functions of ISE, such as certificates, network access devices, authentication and authorization policies, guest access, BYOD, and TrustSec. Per-canned configurations are predefined templates that provide common settings and values for ISE components, such as policy sets, authorization profiles, and network conditions. The user can apply these templates to quickly configure ISE for specific use cases, such as 802.1X, MAB, or web authentication3.

The other options, Cisco Active Advisor and ISE command line, are not accurate descriptions of ISE configuration capabilities. Cisco Active Advisor is a separate cloud-based service that provides network health and security checks, device lifecycle management, and best practice recommendations for Cisco devices. It is not directly related to ISE deployments. ISE command line is an interface that allows the user to perform administrative tasks, such as backup and restore, password recovery, and troubleshooting. However, ISE does not require an understanding of the command line for set-up and configuration, as most of the functions can be done through the graphical user interface (GUI). References := : 1: ISE Deployment Assistant (IDA) - Cisco Identity Services Engine - Cisco, 2: Cisco Identity Services Engine Administrator Guide, Release 2.7 - Wireless Setup Wizard [Cisco Identity Services Engine] - Cisco, 3: Cisco Identity Services Engine Administrator Guide, Release 2.7 - ISE Wizards [Cisco Identity Services Engine] - Cisco, : Cisco Active Advisor - Cisco, : Cisco Identity Services Engine CLI Reference Guide, Release 2.7 - Using the Command-Line Interface [Cisco Identity Services Engine] - Cisco

The Cisco V-Edge Router performs QoS traffic classification on the ingress interface, before the traffic enters the VPN. The classification is based on the match criteria specified in the access lists, which can include the source and destination IP addresses, ports, protocols, DSCP values, and application-aware NBAR attributes. The classification results in assigning a forwarding class and a QoS group to each packet. The forwarding class determines the output queue and the scheduling policy for the packet on the egress interface. The QoS group is an internal label that can be used to remark the DSCP value of the packet or to match the packet in another access list for further processing. References:
