NEW QUESTION # 14
Which of the following statements about the gateway-less data center interconnect solution is FALSE?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In a gateway-less DCI design, there is no dedicated gateway device performing EVPN-to-WAN service interworking. Instead, the data center EVPN overlay is extended across the WAN more directly. Because leaf routers must establish overlay reachability across sites, the IP addresses of the leaf VTEPs need to be reachable through the WAN, commonly by redistributing or otherwise carrying the necessary loopback reachability. The WAN transparently carries the EVPN/VXLAN overlay, and leaf routers can establish VXLAN tunnels across the WAN to remote leaves. Option D is false because it introduces "data center gateway routers" maintaining MP-BGP EVPN peering with the data center route reflector. That is not the gateway-less model; it describes a gateway-based role that does not exist as a separate function in this architecture. In gateway-less DCI, the EVPN control-plane and VXLAN data-plane extension are handled by the fabric endpoints themselves, so the design trades demarcation and interworking control for a more direct overlay extension model. Reference: gateway-less DCI, WAN reachability for leaf VTEPs, transparent EVPN overlay carriage, VXLAN tunnel extension.
NEW QUESTION # 15
Consider the exhibit.
Which of the following statements about the configuration and operation of this setup is FALSE?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
This setup represents single-active Layer 2 EVPN multi-homing. In single-active mode, the Ethernet Segment is configured so that only one PE acts as the active forwarding node for a given service, while the other remains standby. The ports connecting to the host are associated with ES-1 so the EVPN control plane can perform Ethernet Segment discovery, DF election, and standby behavior. If Leaf1 is the active/DF node for the service, all traffic to and from the host flows through Leaf1 until a failure or DF transition occurs. Option D is false because a host LAG is not required for this single-active topology. A LAG is typically required for all-active L2 multi-homing, where the host must treat multiple physical links toward different leaf routers as one logical bundle. In single-active operation, the host can be connected through separate physical links or active/standby access behavior without requiring LACP bundling. The EVPN PEs enforce the active path selection through DF and ES state rather than relying on host-side LAG hashing. Reference: single-active EVPN multi-homing, Ethernet Segment port association, DF-controlled active forwarding.
NEW QUESTION # 16
Consider the exhibit.
Which of the following is NOT configured on dcgw10 to support the Layer 3 VPN connectivity?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In an integrated gateway-based data center interconnect design, the gateway must interwork between the data center EVPN/VXLAN domain and the WAN VPN transport domain. For Layer 3 VPN connectivity on a Nokia 7750 SR integrated gateway, the base BGP instance must support the relevant VPN address families, such as VPN-IPv4 and EVPN, because the gateway participates in control-plane exchange between the data center and WAN sides. The VPRN must also be associated with the WAN transport, normally through MPLS tunnel binding, and the VRF target must match the corresponding VPRN on the remote gateway so that VPN routes are imported and exported correctly. A routed VXLAN interface, however, is an SR Linux IP-VRF/VXLAN construct used for symmetric L3 EVPN forwarding inside a VXLAN-based data center fabric. In this question, dcgw10 is acting as the integrated WAN gateway for L3VPN connectivity, so a routed VXLAN interface is not the required configuration item on the VPRN instance. Reference: integrated gateway DCI, VPRN over MPLS, EVPN-to-VPN interworking.
NEW QUESTION # 17
Which of the following statements about the gateway-less data center interconnect solution is FALSE?
Answer: D
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
A gateway-less DCI design extends the data center EVPN/VXLAN model across the WAN without a distinct gateway function separating the data center fabric from the WAN VPN edge. Because the leaf routers or route reflectors must establish the necessary EVPN control-plane and VXLAN data-plane reachability across data centers, the WAN must provide reachability for those fabric endpoints. This design can simplify service continuity and preserve the EVPN overlay model end-to-end, but it does not provide the clean security and QoS demarcation that exists in a decoupled gateway model. A clear demarcation between a border leaf and a separate gateway/WAN PE is specifically a property of decoupled gateway-based DCI, not gateway-less DCI. The gateway-less model also requires reachability between route reflectors or EVPN control-plane endpoints across sites. Therefore, option A is false because it incorrectly assigns the demarcation benefit to the gateway-less design. Reference: gateway-less DCI, stretched EVPN overlay, route-reflector and leaf reachability requirements.
NEW QUESTION # 18
When providing L3 multi-homing on two or more leaf routers, which of the following is FALSE?
Answer: A
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
Layer 3 multi-homing is fundamentally about redundant or load-balanced L3 reachability for external prefixes, not about Layer 2 broadcast-domain flooding toward a host. In single-active L3 multi-homing, DF election determines which attached leaf is active for the Ethernet Segment, and only that leaf advertises or forwards for the attached customer route as required by the redundancy model. In all-active L3 multi-homing, multiple leaf routers can be valid next-hops for the same learned third-party prefix, and remote PEs may load-balance toward them based on the Ethernet Segment association. Learned external prefixes are carried as EVPN route type 5 IP Prefix routes, which is the correct route type for L3 reachability. The Ethernet Segment is associated with the next-hop for those prefixes so that remote PEs understand the multi-homed nature of the path. Option B is false because BUM forwarding is a Layer 2 EVPN concern. In an all-active L3 multi-homing scenario, DF election is not used to identify a BUM-forwarding leaf for host traffic in the same way it is used in Layer 2 multi-homing services. Reference: L3 EVPN multi-homing, RT-5 prefix routes, ES next-hop behavior.
