In an Edge-Routed Bridging (ERB) architecture, where is the anycast gateway for a VLAN typically implemented?

On a centralized router outside the fabric

On a dedicated firewall appliance

A network engineer is analyzing the traffic flow in an EVPN-VXLAN fabric. They observe that all inter-subnet traffic between servers on different leaves must traverse the spine for routing. Which architecture is in use?

A Layer 2-only fabric without routing

A hybrid architecture with anycast gateways

An enterprise is deploying an EVPN-VXLAN fabric and has a workload that generates a high volume of east-west traffic between two servers connected to different leaf switches. The network team wants to minimize the latency for this traffic. Which architecture should they use, and why?

CRB, because the spine can route the traffic faster than the leaf

ERB, because it uses VXLAN routing at the spine, which is faster

ERB, because the leaf can route the traffic locally without involving the spine

CRB, because it uses anycast gateways that optimize the path

A company is designing an EVPN-VXLAN fabric and has a limited number of IP addresses available for the underlay. They want to minimize the number of IP addresses used for the VTEPs. Which architecture should they choose?

ERB, because it uses fewer VTEPs

Neither, because both architectures require the same number of VTEPs

CRB, because it can use a single VTEP for the entire fabric

CRB, because it uses fewer VTEPs

Part of the EVPN-VXLAN Signaling domain, which makes up ~27% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~9–16 in this domain), expect 1–2 from this objective — we provide 19 practice questions to prepare you well beyond it.
