Cisco SD-WAN solution is designed to provide a highly secure cloud-based open architecture that is programmable and scalable at the same time. It can be managed through a Graphic User Interface called Cisco vManage console. Using the Cisco vManage console, the IT professionals can connect data centers, branch, and regional offices. This Cisco SD-WAN solution provides efficiency in network speed along with security because it is centrally managed. Cisco being the pioneer in the networking IT industry has widely deployed Cisco SD-WAN solutions worldwide. This system has been deployed to as many as all the fortune 2000 businesses, and it is growing day by day. These fortune 2000 enterprises include healthcare, retail, energy, manufacturing, oil & gas, logistics, etc. The Cisco SD-WAN solution has solved many critical problems in the IT industry related to these fortune 2000 enterprises. This has reduced the overall costs. The enterprises can get better-centralized controls of managing and analyzing across the WAN. It is also helpful in deploying the complete security solution to co-location, branches, regional office at lower costs with no compromise in data security. Following are the security feature of the Cisco SD-Wan solution: • Enterprise Firewalls • Secure Web Gateway • DNS layer security & URL filtering • Built-in Intrusion prevention system • Cloud Access Security Broker (CASB) • Malware protection The Cisco SD-WAN solution supports multitenancy because multiple users can be created, and a separate VPN can be assigned to each user. In short, the Cisco SD-WAN solution comes up with many features that can be counted to reduce the costs and improve the enterprise network's security. Cisco provides fully integrated communication support for its SD-WAN solution. Cisco offers certification courses that come up for different domains and different entry-level. For example, they have the necessary entry-level qualification for the newly joined IT networking associates, and they have medium and expert level qualifications. The basic level qualification for IT networking associates is CCNA, which is the basic entry-level. CCNP is for the IT networking professional, and it is a medium level certification. CCIE is the highest expert level qualification, which is also respected and highly paid certification worldwide. The CCIE expert can design, plan, implement, troubleshoot, and secure any given network. CCIE exam consists of two parts: the written and the second is lab; however, passing this exam is difficult. The individual has to give both of the two parts to get CCIE certification. CCIE experts are also able to demonstrate and deploy the Cisco SD-WAN solution. Here are a few voice and application optimization features which are supported by the Cisco SD-WAN solution; • Cisco SD-WAN supports FEC and packet duplication for voice optimization. • Cisco SD-WAN supports TCP optimization for internet optimization. • Cisco SD-WAN supports SLA dynamic routing based on real-time network telemetry for on-premises applications. • Cisco SD-WAN also supports dynamic routing based on cloud and telemetry for SaaS applications. In conclusion, Cisco SD-WAN users can find it a predictable application that can be used to increase the user's productivity by optimizing the cloud or their on-premises application with real-time results. However, making a career in the IT networking industry requires a lot of practice, as mentioned above, because Cisco certifications are the only way to demonstrate your skills on Cisco SD-WAN solution an employer can trust. With Cisco exam dumps and solving SPOTO cisco practice tests can lead to earning Cisco's certification bypassing their exam even in the first attempt.
