You are deploying a new network to support your AI workloads on devices that support at least 400 Gbps Ethernet. There is no requirement for any Layer 2 VLANs in this network. Which network architecture would satisfy this requirement?

• A. an IP fabric using the EVPN-MPLS architecture
• B. an IP fabric with an EVPN-VXLAN architecture
• C. an IP fabric using the PIM-SM to signal VXLAN overlay
• D. an IP fabric using EBGP

You are asked to build redundant gateways in your EVPN-VXLAN environment, but you must conserve address space because these gateways must span across seven PEs. What should you implement on the PEs to satisfy these requirements?

• A. Use IRB interfaces with the same IP and MAC address
• B. Use IRB interfaces with the same IP address and different MAC addresses
• C. Use IRB interfaces with different IP addresses and the same VGA
• D. Use IRB interfaces with the same IP and VGA

• A. The inner packet fields are not used in the hash load balancing
• B. The destination port in the UDP header is used to load balance VXLAN traffic
• C. The source port in the UDP header is used to load balance VXLAN traffic
• D. The inner packet fields are used in the hash for load balancing

You are asked to automatically provision new Juniper Networks devices in your network with minimal manual intervention. Before you begin, which two statements are correct? (Choose two.)

• B. You must have a DHCP server that provides the location of the software image and configuration files
• C. You must have a file server that stores software image and configuration files
• D. You must have an NTP server to perform time synchronization

You are using a single tenant data center with a bridged overlay architecture. In this scenario, how do hosts of the different virtual networks communicate with each other?

• A. using anycast gateway addresses configured on the leaf devices
• B. using EVPN Type 5 routes
• C. off-fabric using an external device
• D. using virtual gateway addresses configured on the spine
