Score Higher on Verified 500-490 | Designing Cisco Enterprise Networks (ENDESIGN) exam Exam Questions with Answers

The overall health page of the assurance component in the Cisco DNA Center displays two primary categories: Client and Network1. The Client category shows the health score of all the wired and wireless clients connected to the network, along with the number of clients, the top issues affecting the clients, and the distribution of clients by type, OS, and SSID1. The Network category shows the health score of all the network devices, such as switches, routers, wireless controllers, and access points, along with the number of devices, the top issues affecting the devices, and the distribution of devices by site, family, and role1.

The other options are not primary categories on the overall health page. Server is not a category, but a type of client that can be filtered in the Client category1. Access-Distribution and Core are not categories, but roles of network devices that can be filtered in the Network category1. Wired is not a category, but a subcategory of the Client category that shows the health score of the wired clients only1.

The Proactive Insights feature of Cisco DNA Center Assurance is a function that generates synthetic traffic to perform tests that raise awareness of potential network issues. This feature uses the Cisco DNA Center platform to create and schedule tests that simulate real user traffic and measure the network performance and user experience. The tests can be run on demand or periodically, and the results are displayed in the Cisco DNA Center dashboard. The Proactive Insights feature helps network administrators to proactively identify and troubleshoot network issues before they affect the end users12. References:

Understanding Cisco DNA Center Assurance!

 The current time in enterprise networking history is characterized by the rapid pace of change in the network technologies, architectures, and services. Some of the factors that contribute to this change are:

The increasing demand for network performance, scalability, reliability, security, and agility from the business and end users.

The emergence of new network paradigms, such as software-defined networking (SDN), network function virtualization (NFV), cloud networking, and intent-based networking (IBN).

The proliferation of network devices, applications, and data sources, such as the Internet of Things (IoT), mobile devices, cloud services, big data, and artificial intelligence (AI).

The evolution of network standards, protocols, and best practices, such as IPv6, 5G, Wi-Fi 6, Ethernet, and network automation.

These factors create new opportunities and challenges for enterprise network designers, engineers, and administrators, who need to keep up with the latest trends and innovations, and adapt their network solutions to the changing business and technical requirements.
