A company is deploying EVPN-VXLAN for DCI with two VTEPs at each site. The network team wants to ensure that if one VTEP fails, the other VTEP can continue forwarding traffic for the stretched VLAN without causing MAC address flapping. Which configuration is required?

Configure both VTEPs with the same IP address and rely on the underlay to load balance

Configure an Ethernet Segment Identifier (ESI) and designate one VTEP as the designated forwarder (DF)

Configure static MAC addresses on both VTEPs

Use VRRP on the VTEPs for the VXLAN traffic

A network architect is designing a DCI between two data centers. The company has a mix of applications: some require Layer 2 adjacency for legacy reasons, while others are purely IP-based. The architect is concerned about the failure domain and wants to minimize the risk of a broadcast storm affecting both sites. Which design principle should guide the decision?

Use static routes for all inter-site traffic and avoid dynamic routing

Stretch only the VLANs that require Layer 2 adjacency and use Layer 3 routing for the rest

Stretch all VLANs to both sites to ensure seamless mobility for all applications

Use a single VPLS instance for all VLANs to simplify the design

Which EVPN route type is used to advertise MAC addresses for Layer 2 stretch?

Ethernet Auto-Discovery (Type 1)

What is a key configuration consideration when using BGP for Layer 3 stretch?

Configuring BGP peers between sites and advertising the appropriate prefixes

Configuring VXLAN on all routers

Disabling all routing protocols

Which scenario is a typical use case for Layer 3 stretch between data center sites?

Live migration of VMs without changing IP addresses

Extending a single broadcast domain across sites

Replacing the need for a firewall between sites

Active-active web servers that need to share the same virtual IP address

Layer 2 and Layer 3 Stretch JN0-683 Practice Questions (Page 2)

Part of the Data Center Interconnect domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 1–2 from this objective — we provide 27 practice questions to prepare you well beyond it.
