WAN aggregation is represented by the central router that connects multiple branch sites through a Carrier Ethernet service to the enterprise WAN, consolidating traffic.

Private WAN is shown through the use of Carrier Ethernet, which is a private service providing secure, dedicated connectivity between branches and the enterprise WAN.

A Secure Web Gateway (SWG) provides proxy services to inspect and filter web traffic and includes firewall capabilities to enforce security policies, block threats, and control access to internet resources.

Cloud Access Security Brokers (CASBs) provide key functions such as visibility into cloud application usage and compliance enforcement by monitoring, auditing, and applying policies to ensure adherence to security and regulatory standards.

The exhibit shows a hierarchical structure with Leaf, Spine, and Super Spine layers. This architecture is characteristic of a 7-stage IP fabric, which is used in large-scale data centers to provide high scalability and bandwidth. It extends the 3-stage fabric by adding an additional spine layer (Super Spine) for interconnecting multiple spine layers.

Using discrete border leafs enables design flexibility, such as applying different oversubscription ratios for east-west (intra-fabric) and north-south (external) traffic. This separation improves scalability and performance tuning compared to placing border roles directly on spines.

MX Series routers are high-performance, scalable routers used in various roles such as data center interconnects, service provider backbones, and edge networks. They support advanced routing, MPLS, and security features, making them ideal for these critical infrastructure areas.

Fault management helps detect and address potential issues before downtime occurs, while measuring network performance, errors, and security metrics enables administrators to make data-driven decisions for maintaining and optimizing the network.

cSRX and vSRX are the virtualized versions of the Juniper SRX Series firewalls designed for deployment in virtual environments. The cSRX is containerized, while the vSRX is a VM-based firewall, both supporting advanced security services in cloud or virtualized data centers.

VXLAN is a network virtualization technology that provides a Layer 2 overlay over a Layer 3 underlay. It enables the extension of Layer 2 segments across a Layer 3 infrastructure, facilitating scalable multi-tenant data center networks.
