NEW QUESTION # 14
Which of the following statements about the decoupled gateway-based 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 decoupled gateway-based DCI design, the data center border leaf and the WAN PE are separate devices. Traffic between them can be identified using VLAN tags, allowing different data center EVPN services to be mapped to corresponding WAN VPN services. This architecture provides a clean operational boundary: the border leaf remains aligned with the data center EVPN/VXLAN fabric, while the WAN PE handles WAN VPN transport, QoS, security policy, and service interconnection. The separation gives a strong demarcation point for troubleshooting and administrative control. Option D is false because the WAN PE does not maintain an MP-BGP EVPN peering session with the data center route reflector. In the decoupled model, the route reflector remains part of the data center EVPN control plane, while the WAN PE exchanges routing or service information with the border leaf through the local handoff model. Direct WAN PE-to-data-center-RR peering would blur the separation that defines the decoupled design and would make the WAN PE part of the data center EVPN overlay control plane, which is not the intended architecture. Reference: decoupled gateway DCI, VLAN handoff, WAN VPN mapping, security/QoS demarcation, route-reflector separation.
NEW QUESTION # 15
Which of the following statements about a BGP route target is FALSE?
Answer: C
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
A BGP route target is an extended community used to control which EVPN routes are imported into which MAC-VRF or IP-VRF. It is carried with EVPN updates and acts as the import/export policy tag for tenant service membership. The statement that it is a BGP extended community is correct. It is also correct that route targets support multi-tenant operation, because they allow different EVPN instances to carry potentially overlapping MAC or IP information while importing only the routes intended for that service. However, option D is false in the wording used here. The route target does not itself identify the EVPN instance in the control plane as a unique route identifier. That role is more closely associated with the route distinguisher and EVPN NLRI construction, while the route target determines import eligibility. A route target tells a receiving PE whether the route belongs in a local service instance, but it is not the unique identity of the EVPN route. This distinction is critical: route distinguishers make routes unique; route targets control route distribution and service membership. Reference: EVPN route targets, BGP extended communities, route import/export policy, RD versus RT function.
NEW QUESTION # 16
Which of the following EVPN route-types is used to implement aliasing?
Answer: C
NEW QUESTION # 17
When PEs are connected to an Ethernet segment with at least one active MAC-VRF, which of the following statements about the AD per EVI updates sent by a PE 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]:
Ethernet Auto-Discovery per EVI routes are EVPN route type 1 advertisements used in multi-homing at the service-instance level. A PE sends an AD per EVI route for each MAC-VRF associated with the Ethernet Segment. These routes allow remote PEs to understand that the advertising PE has reachability to a given EVI through the shared ES. They are also used for aliasing and fast convergence, because a remote PE can treat multiple attached PEs as valid paths for traffic toward the same multihomed segment. In VXLAN EVPN, the update can include data-plane information such as the VNI, and it carries route-target information so the route is imported into the correct MAC-VRF. Option B is false because the multi-homing type or redundancy mode is not carried in the AD per EVI update as stated. Redundancy behavior is associated with Ethernet Segment-level signaling and configuration, especially ES discovery and related route attributes, not with AD per EVI as the mechanism that declares the multi-homing type. Reference: EVPN RT-1 AD per EVI, MAC-VRF association, route target, VNI, aliasing.
NEW QUESTION # 18
Which of the following statements about the Layer 2 EVPN configuration/operation in a Nokia SR Linux is FALSE?
Answer: C
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In SR Linux, a Layer 2 EVPN service is implemented using a MAC-VRF network instance. The MAC-VRF represents the tenant bridge domain and is associated with access subinterfaces and a VXLAN data-plane mapping. Local hosts are learned through the data plane when Ethernet frames arrive on local interfaces. Remote hosts, however, are not learned by flooding or by configuring static per-peer VXLAN interfaces. They are learned through MP-BGP EVPN updates, especially EVPN route type 2 MAC/IP Advertisement routes. Option B is false because SR Linux does not require a separate manually configured VXLAN interface toward each remote VTEP for the MAC-VRF. Instead, the MAC-VRF is bound to VXLAN encapsulation and a VNI, while remote VTEPs and their MAC reachability are discovered dynamically through the EVPN control plane. This is one of the central advantages of EVPN compared with static VXLAN flood-and-learn models: the overlay endpoints and endpoint reachability are signaled through BGP, reducing manual configuration and improving scale. Reference: SR Linux L2 EVPN MAC-VRF configuration, MP-BGP EVPN learning, VXLAN data-plane mapping.
