NEW QUESTION # 53
Consider the exhibit.
Which of the following statements 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]:
In an SR Linux Layer 2 EVPN MAC-VRF, locally attached MAC addresses are learned through the data plane on local access interfaces, while remote MAC addresses are learned from MP-BGP EVPN control-plane advertisements and installed with a VXLAN next-hop. The exhibit shows one local learned MAC on an Ethernet subinterface and another MAC learned through EVPN with a VXLAN interface and VNI 100. The remote VTEP or next-hop information identifies the remote endpoint, and the VNI maps the received VXLAN traffic to the correct MAC-VRF service. The false statement is C because saying that the MAC address associated with the vxlan-interface "will not age out" is too absolute. A remote EVPN MAC is not aged in the same way as a local data-plane-learned MAC, but it can still be removed when the corresponding EVPN route is withdrawn, invalidated, or no longer present in the control plane. The "N/A" style aging behavior does not mean permanent retention. Reference: SR Linux MAC-VRF verification, local MAC learning, EVPN-learned remote MACs, VXLAN VNI mapping.
NEW QUESTION # 54
A host is connected to a MAC-VRF on leaf1 and leaf2. The MAC-VRF interfaces on leaf1 and leaf2 are associated to an Ethernet segment configured for active-standby multi-homing.
Which of the following statements 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 active-standby, or single-active, Layer 2 EVPN multi-homing, only one PE is active for the Ethernet Segment and MAC-VRF at a time. Leaf1 and Leaf2 participate in DF election, and the elected DF becomes the active forwarding PE for that service attachment. Because this is not all-active multi-homing, the non-DF must not forward traffic to the host for the protected service. This prevents duplicate frames, incorrect MAC learning, and loops on the access side. The DF accepts traffic from the host and forwards BUM traffic received from remote PEs toward the host-facing segment. Option D is false because it claims that the non-DF can forward unicast traffic from remote PEs to the host. In single-active operation, remote peers must direct traffic to the active PE, and the standby PE remains ready to take over only after DF state changes. This is the operational distinction from all-active multi-homing, where more than one PE may be used for forwarding depending on the traffic type and aliasing behavior. Reference: single-active L2 EVPN multi-homing, DF role, non-DF forwarding suppression.
NEW QUESTION # 55
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.
NEW QUESTION # 56
Leaf routers are configured to support Layer 2 multi-homing all-active mode.
Which of the following statements 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]:
For Layer 2 all-active EVPN multi-homing on SR Linux, the Ethernet Segment configuration is the control-plane anchor that binds the redundant access attachment to EVPN. The relevant LAG subinterfaces must be associated with the Ethernet Segment so that the PE can advertise the segment correctly and apply split-horizon and aliasing behavior. The Ethernet Segment must also be administratively enabled; otherwise, the PE will not participate properly in ES discovery and DF procedures. The multi-homing mode must be set to all-active to permit forwarding through multiple attached leaf routers and support host-side LAG operation. The false statement is option B. The Ethernet Segment Identifier has a defined structure, and the blanket statement that the 2nd through 7th octets "must not be all zeros" is not a valid requirement as stated. What matters operationally is that the ESI uniquely identifies the same multi-homed Ethernet Segment across participating PEs and is consistently configured where required. The ESI must be non-zero as a meaningful segment identifier, but the specific octet restriction in the option is not the SR Linux all-active configuration rule. Reference: SR Linux L2 EVPN all-active multi-homing, Ethernet Segment configuration, LAG association.
NEW QUESTION # 57
Consider the exhibit.
All IP-VRFs are configured properly and are operational.
Which of the following statements 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 single-active EVPN multi-homing design, the connected PE routers perform Designated Forwarder election to determine which PE is active for the relevant service or Ethernet Segment. The DF is responsible for forwarding toward the attached segment and, in a Layer 3 multi-homing case, only the active/DF PE advertises the customer IP prefix route toward the EVPN control plane. Single-active redundancy is communicated using Ethernet Segment-related EVPN procedures, including Ethernet A-D information, so remote PEs can identify the redundancy behavior and avoid forwarding traffic to an inactive attachment. The false statement is that the elected DF uses an AD per EVI update to identify itself as primary. AD per EVI is primarily used to advertise per-service Ethernet Segment reachability and support aliasing/load-balancing behavior in multi-homed services. DF election itself is driven by Ethernet Segment route procedures, not by the DF declaring itself primary through AD per EVI. Therefore, option B misstates the role of AD per EVI in the single-active L3 multi-homing control plane. Reference: EVPN DF election, single-active multi-homing, Ethernet A-D routes.
