Cisco ACI refers to Cisco Application Centric Infrastructure, a software-defined networking architecture for automating and managing data center networks through policy-based control. This skill involves designing application-centric policies, configuring fabric components such as leaves, spines, tenants, and endpoint groups, and integrating Cisco ACI with virtualization platforms and external networks. It is used to standardize network configurations, enforce security and segmentation, and monitor and troubleshoot data center network operations through centralized management.

Cisco DNA Center refers to a network management and automation platform that simplifies the management of network infrastructure. This skill encompasses the ability to design, provision, and manage networks through a centralized dashboard, enabling users to automate tasks, monitor performance, and ensure security compliance. Knowledge of Cisco DNA Center is utilized to enhance operational efficiency, streamline network operations, and facilitate troubleshooting by providing insights into network performance and health.

Data Center Networks refer to the interconnected systems within data centers that enable the transfer, storage, and management of data. They support communication between servers, storage devices, and external networks to ensure efficient data processing and accessibility.

EVPN (Ethernet VPN) is a specialized networking protocol that allows different devices to communicate with each other over a virtualized Ethernet network. It is commonly used in data center environments to provide efficient and scalable connectivity for VLANs, virtual machines, and other networking resources. EVPN offers features such as multi-tenancy, seamless mobility, and integration with various types of routing protocols. It also supports advanced features like network virtualization, load balancing, and network slicing, making it a valuable tool for modern IT infrastructure. Given its complexity, EVPN requires specialized skills and expertise to implement and manage effectively.

Software-Defined Networking Wide Area Network (SD-WAN) is a technology that abstracts network control and enables centralized management of network resources. It dynamically optimizes traffic routing across multiple network paths, including MPLS, broadband, and LTE, based on application requirements and network conditions. SD-WAN enhances network agility, performance, and security while reducing costs associated with traditional WAN deployments.
