NEW QUESTION # 55
Which of the following statements about the configuration of a distributed Layer 2 EVPN 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]:
A distributed Layer 2 EVPN in SR Linux is implemented using MAC-VRF network instances, EVPN control-plane signaling, and VXLAN data-plane encapsulation. A common mistake is assuming that every PE must use the same EVI value for the same L2 service. In SR Linux, the important operational requirement is that the correct EVPN routes are imported and exported using matching route-target policy, not necessarily that every PE has the same locally configured EVI. Therefore, option A is false. The route distinguisher can be automatically generated using local values such as the autonomous system number and EVI, giving each PE's EVPN routes uniqueness in MP-BGP. A MAC-VRF is associated with VXLAN encapsulation for its data-plane service mapping, and route targets may need to be manually configured when leaf routers are in different autonomous systems because automatic derivation may not produce matching import/export policy across AS boundaries. The key separation is this: the RD gives uniqueness, the route target controls service membership, and the EVI is a local service identifier rather than a universal mandatory match in all designs. Reference: SR Linux distributed L2 EVPN configuration, EVI, RD auto-generation, route-target policy.
NEW QUESTION # 56
Which of the following is NOT part of the description of a BGP route-distinguisher?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
A route distinguisher is used in MP-BGP VPN and EVPN address families to make otherwise overlapping tenant routes unique in the BGP control plane. In EVPN, different tenants or EVPN instances may legitimately use the same MAC or IP values. The route distinguisher makes the NLRI globally unique by prepending a unique value to the tenant route. It is typically unique per PE and per EVI, and it is carried in EVPN route advertisements. However, the route distinguisher does not control route import, export, or service membership. That role belongs to the route target, which is a BGP extended community used by receiving PEs to decide which EVPN instance should import the route. Therefore, option D is not part of the correct description of a route distinguisher. Saying that the RD identifies the EVPN instance in the control plane confuses RD uniqueness with route-target membership. The RD makes routes unique; the route target associates those routes with the appropriate MAC-VRF or IP-VRF import policy. Reference: EVPN route distinguisher, overlapping tenant addresses, route target separation.
NEW QUESTION # 57
Which of the following statements about the decoupled gateway-based data center interconnect solution is TRUE?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
A decoupled gateway-based DCI model separates the data center border-leaf function from the WAN PE function. This separation is the key design point. The border leaf remains part of the data center EVPN/VXLAN environment, while the WAN PE participates in WAN VPN transport and policy enforcement. Because the roles are split across two devices, the handoff between the border leaf and WAN PE provides a clean administrative and operational boundary. That boundary is useful for security policy, QoS marking, traffic classification, and troubleshooting ownership. The WAN does not need direct reachability to every leaf and route reflector as in a gateway-less model. The WAN PE also does not peer directly with the data center route reflector in a decoupled model; route exchange occurs through the border-leaf/WAN-PE handoff. VXLAN tunnels between leaf routers across different data centers are characteristic of gateway-less extension, not decoupled gateway operation. Therefore, the statement about clear demarcation between the data center border leaf and WAN PE is the accurate description. Reference: decoupled gateway-based DCI, security/QoS demarcation, WAN PE separation.
NEW QUESTION # 58
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 # 59
Which of the following statements about the configuration of a Layer 3 multi-homing with a centralized router 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]:
Layer 3 EVPN multi-homing with a centralized router uses an Ethernet Segment to associate multiple leaf routers with a common external L3 attachment. The centralized router is part of that attached segment from the forwarding perspective, and the connected leaf routers advertise third-party or customer prefixes into EVPN so that remote leaves can reach those prefixes through the multi-homed attachment. For L3 EVPN, learned customer prefixes are normally advertised using EVPN route type 5, which carries IP prefix reachability. In an all-active design, remote leaf routers may load balance traffic to the customer prefix through multiple attached leaf routers because the ES next-hop allows the remote PE to understand that the prefix is reachable through a multi-homed Ethernet Segment. The false statement is that every router participating in the Ethernet Segment must be configured with all-active mode. Multi-homing mode is a design and configuration property of the EVPN PEs participating in the ES, and designs may use single-active or all-active behavior depending on redundancy and forwarding requirements. Reference: L3 EVPN multi-homing, centralized router attachment, EVPN RT-5 prefix advertisement.
