NEW QUESTION # 25
Consider the exhibit.
Leaf-1 has received an ARP request from host-1 for host-2. Leaf-1 has added host-1's MAC address in its MAC table and host-1's MAC/IP addresses in its proxy-ARP table.
Which of the following steps 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]:
When Leaf-1 receives an ARP request from Host-1, it learns the source MAC address in the local MAC table and learns the source IP/MAC binding in the proxy ARP table. For EVPN distribution, the relevant control-plane advertisement is an EVPN route type 2 MAC/IP advertisement containing Host-1's MAC and the actual host IP address, 192.168.100.1. This allows remote PEs to populate their EVPN-derived forwarding and proxy ARP state with the correct endpoint binding. Option A is false because advertising the host MAC with the IP address set to 0.0.0.0 does not represent the learned MAC/IP binding required for proxy ARP synchronization. A MAC-only RT-2 advertisement may exist in EVPN contexts, but the question specifically states that Leaf-1 has learned the MAC/IP binding through ARP and is distributing that information. Therefore, the valid advertisement must include the real host IP address. Remote PEs use the MAC/IP route to learn the endpoint, not an all-zero IP placeholder for this proxy ARP learning event. Reference: EVPN RT-2 MAC/IP advertisement, proxy ARP table population, endpoint synchronization.
NEW QUESTION # 26
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 # 27
Consider the exhibit.
Host-2 is sending data to Host-1. The network is designed to use asymmetric routing.
Which of the following statements about the operation of the data plane is TRUE?
Answer: D
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In asymmetric EVPN IRB, the ingress PE performs routing from the source subnet into the destination subnet, then forwards the packet across the VXLAN overlay using the destination MAC-VRF/VNI. The egress PE does not perform another IP-VRF lookup for that packet; it performs Layer 2 forwarding in the destination MAC-VRF. In this scenario, Host-2 sends traffic toward Host-1. After the ingress routing decision, the traffic arrives at Leaf-2 in the context of the destination MAC-VRF, mac-vrf-1. Leaf-2 then performs a MAC lookup in mac-vrf-1 and forwards the frame to Host-1. Option D is therefore correct. Option A reverses the forwarding direction and misidentifies the leaf action. Option B incorrectly sends mac-vrf-2 traffic toward the IP-VRF on Leaf-2, even though Leaf-2 is acting as the egress PE for Host-1. Option C is also incorrect because the egress forwarding action is based on the MAC table in the destination MAC-VRF, not an IP-VRF ARP lookup at that stage. Reference: asymmetric L3 EVPN IRB data-plane operation, ingress routing and egress MAC forwarding.
NEW QUESTION # 28
Which of the following statements about the configuration of a Layer 3 multi-homing with a centralized router 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 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.
NEW QUESTION # 29
When configuring the EVPN MP-BGP route reflector sessions between the leaf and spine routers, which of the following statements is TRUE?
Answer: D
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In SR Linux BGP configuration, parameters defined at a more specific hierarchy level can override broader protocol-level settings. Therefore, if a `local-as` value is configured within the BGP group used for EVPN MP-BGP route-reflector sessions, that value overrides the AS number configured directly under the BGP protocol for that group's sessions. Option A is correct. Option B is false because the cluster ID is configured on the route reflector, not on every participating client. The cluster ID identifies the RR cluster and helps prevent route-reflection loops. Option C is false because redundant route reflectors normally operate in parallel rather than as strict primary/backup devices; clients can peer with both for resilience. Option D is misleading because EVPN route reflectors are used to avoid a full mesh of overlay MP-BGP EVPN sessions between leaves, not to replace ordinary underlay eBGP leaf-spine routing sessions. In a clean fabric design, the underlay provides IP reachability, while the EVPN overlay uses MP-BGP sessions, often via route reflectors, to distribute tenant reachability. Reference: SR Linux BGP hierarchy, EVPN route reflector sessions, local-AS override, cluster ID behavior.
