질문 # 23
Which of the following statements about a BGP route target is FALSE?
정답：A
설명：
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.
질문 # 24
Which of the following statements about a distributed Layer 2 EVPN is FALSE?
정답：A
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In a distributed Layer 2 EVPN service, the local leaf learns host reachability from frames received on access interfaces. When a host replies to an ARP request, the local leaf can learn the source MAC address from the Ethernet frame and install it in the MAC forwarding table. If the ARP payload contains an IP/MAC binding, the PE can also use that information for proxy ARP and EVPN MAC/IP advertisement. The local PE then advertises the learned endpoint reachability using EVPN route type 2 to its BGP EVPN peers or route reflector. The false statement is B. The ARP reply is not replicated to every leaf in the flooding list as a normal operation. EVPN's purpose is to reduce unnecessary flooding by distributing endpoint reachability through the control plane. BUM replication is used for broadcast, unknown unicast, and multicast traffic when needed, but a learned ARP reply does not require blind replication to all remote leaves. Instead, the leaf advertises the learned MAC/IP state through MP-BGP EVPN, allowing remote PEs to install accurate forwarding and proxy ARP state. Reference: distributed L2 EVPN operation, ARP learning, EVPN RT-2 advertisement.
질문 # 25
e-BGP is used as the routing protocol in the data center underlay.
When configuring the EVPN MP-BGP route reflector sessions, which of the following statements is FALSE?
정답：A
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In many SR Linux data center fabrics, eBGP is used in the underlay because it gives simple hop-by-hop routing, fast convergence, and clean autonomous-system separation between leaf and spine nodes. The EVPN overlay, however, is a separate MP-BGP control plane used to distribute EVPN NLRI. The overlay route-reflector session does not have to reuse the leaf's underlay autonomous system number. In practice, an overlay BGP group may use a distinct local AS or configuration model separate from the underlay AS design. Therefore, option B is false. The route reflector's cluster ID is configured on the route reflector itself to prevent reflection loops and identify the RR cluster. Redundant route reflectors can be deployed for resiliency, and clients may receive duplicate paths or duplicate updates from multiple RRs; the BGP decision process and route reflection rules handle this. The key design distinction is that underlay eBGP provides IP reachability between loopbacks, while overlay MP-BGP EVPN carries tenant service reachability. Mixing these roles leads to incorrect AS planning. Reference: SR Linux EVPN MP-BGP route reflectors, eBGP underlay, overlay BGP sessions.
질문 # 26
Which of the following statements describes the function or operation of the integrated gateway-based data center interconnect solution?
정답：D
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In an integrated gateway-based DCI design, the same physical or logical router performs both the data center gateway role and the WAN PE role. This is why option D is correct. The device terminates or participates in the data center-side EVPN service and also handles the WAN-side VPN transport, including route translation or re-advertisement where needed. This approach avoids exposing every data center leaf router to the WAN and avoids requiring route reflector reachability between data centers. It also avoids building VXLAN tunnels directly between all leaf routers in separate data centers. Those characteristics belong to gateway-less DCI, where the EVPN overlay stretches more directly across the WAN and the WAN must carry the underlay or overlay reachability required by the data center leaves. Integrated gateway design is more controlled: the gateway is the interworking point, which makes it suitable when the provider or operator wants a strong service boundary and centralized DCI policy enforcement. Reference: integrated gateway-based DCI, single-router gateway/WAN PE function, EVPN/VPN interworking.
질문 # 27
When providing L3 multi-homing on two or more leaf routers, which of the following is FALSE?
정답：A
설명：
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.
