NEW QUESTION # 15
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: A
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.

Consider the exhibit.
Which of the following statements about the operation of all-active multi-homing 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 an all-active Layer 2 EVPN multi-homing design, the host is normally dual-attached through a LAG to multiple leaf routers that share the same Ethernet Segment Identifier. Leaf1 and Leaf2 both participate in the Ethernet Segment and may receive traffic from the host. For BUM traffic sourced by the host, the host-side hashing can send frames toward either attached leaf. For BUM traffic sent from the EVPN overlay toward the multi-homed segment, DF election controls which PE forwards that replicated traffic toward the local Ethernet Segment to prevent duplicate delivery. The false statement is option B. A remote leaf such as Leaf3 does not simply enable ECMP on the MAC-VRF to load-balance traffic between Leaf1 and Leaf2. EVPN all-active forwarding uses Ethernet Segment discovery, Ethernet A-D routes, aliasing, and split-horizon procedures to determine valid next-hops and prevent loops. ECMP alone is an underlay or routing-table behavior; it is not the MAC-VRF mechanism that authorizes multi-homed L2 forwarding across an Ethernet Segment. Reference: all-active L2 EVPN multi-homing, Ethernet Segment association, DF election, aliasing.
NEW QUESTION # 17
Which of the following statements about the configuration of a distributed Layer 2 EVPN in a Nokia SR Linux 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]:
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 # 18
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 # 19
When providing L3 multi-homing on two or more leaf routers, which of the following 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]:
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.
