Using separate vSwitches for each tenant's network in conjunction with a vSRX device allows for effective isolation and deep packet inspection of inter-tenant traffic. The vSRX can inspect traffic at the hypervisor level without the need for traffic to leave the physical device.

A) VPLS (Virtual Private LAN Service) learns MAC addresses in the data plane, meaning the learning process occurs as the traffic flows through the network.

D) EVPN (Ethernet VPN) differs from VPLS in that it learns MAC addresses in the control plane, using BGP for MAC address dissemination, which offers better scalability and control.

Juniper Networks - Understanding EVPN

Ethernet VPN (EVPN) provides control plane-based MAC address learning. This means that MAC addresses are exchanged and learned via BGP messages rather than through traditional data plane flooding. This approach is more scalable and reliable compared to multicast-based MAC address learning, where MAC addresses are learned through data plane flooding. Control plane learning with EVPN is less prone to issues like broadcast storms and provides a more efficient and stable mechanism for MAC address dissemination in large-scale networks.

The Junos Telemetry Interface (JTI) is the ideal solution for monitoring and telemetry in an IP fabric using QFX Series devices. JTI uses a push model to stream system event data and statistical data from the devices. It provides real-time, granular monitoring capabilities, which is more efficient and scalable compared to traditional polling methods like SNMP. By pushing data to a telemetry server, JTI allows for more dynamic and immediate insights into network performance and health.

To enable communication between VXLANs in different data centers across a WAN connection using an MX Series router, Integrated Routing and Bridging (IRB) interfaces must be configured. IRB interfaces provide Layer 3 routing capabilities within a VXLAN overlay network, allowing for inter-VXLAN routing. By configuring IRB interfaces on the MX router, you enable it to act as a Layer 3 gateway, routing traffic between the different VXLANs across the data centers.
