Referring to the exhibit,you have a data center in which only the spine devices are using EVPN and VXLAN. The leaf nodes are multihomed in active-active mode to the spine nodes through ESI LAG interfaces. In this design, a link failure on the interface connecting the spine nodes would also cause all traffic from the spine to the leaf nodes to drop.In this scenario, which command configured on which nodes would solve this problem?
Answer(s): A
You are evaluating which method to use for learning MAC addresses in your VXLAN network. Which statement is true in this scenario?
Answer(s): B
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.

Referring to the exhibit, which two statements are correct? (Choose two.)
Answer(s): A,D
You are asked to implement a monitoring and telemetry solution for the QFX Series devices in your IP fabric that uses a push model to collect both system event data and statistical data for your QFX Series devices.Which technology satisfies your requirements?
Answer(s): D
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.

You are configuring an MX Series router to act as a Layer 3 gateway to route traffic between VXLANs in different data centers across a WAN connection. In this scenario, what must you do to enable this communication?
Answer(s): C
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.
