500-490 Dumps - Designing Cisco Enterprise Networks (ENDESIGN) exam Practice Exam Questions

The three focus areas for reinventing the WAN are:

Secure Elastic Connectivity: This refers to the ability to provide secure and flexible connectivity to any application, anywhere, and anytime. Secure elastic connectivity enables the network to adapt to the changing business needs and user demands, while maintaining security and performance. Secure elastic connectivity leverages SD-WAN technologies, such as Cloud OnRamp, SASE, and ThousandEyes, to optimize the network path, encrypt the traffic, and monitor the end-to-end visibility across the WAN12.

Application Quality of Experience: This refers to the ability to ensure optimal and consistent user experience for any application, regardless of the network conditions. Application quality of experience uses SD-WAN technologies, such as vAnalytics, to measure and improve the application performance, availability, and reliability across the WAN3. Application quality of experience also uses intelligent policies and real-time analytics to prioritize the critical applications and steer the traffic to the best-performing path4.

Cloud First: This refers to the ability to embrace the cloud as the primary platform for delivering applications and services to the users. Cloud first enables the network to support the multicloud strategy and accelerate the cloud adoption. Cloud first leverages SD-WAN technologies, such as Cloud OnRamp, to simplify and automate the connectivity to the public cloud, SaaS, and cloud interconnect providers4. Cloud first also enables the network to operate as a cloud-native WAN overlay, using software-defined automation and orchestration tools5.
