45. Frage
A host is connected to multiple PEs through multi-homing.
Which of the following is NOT a function of the EVPN route-type 4 route?
Antwort: A
Begründung:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
EVPN route type 4 is the Ethernet Segment route. Its core role is to advertise Ethernet Segment membership so that PEs attached to the same multi-homed segment can discover each other. This discovery is essential for multi-homing procedures such as DF election, split-horizon behavior, and redundancy handling. When multiple PEs advertise the same ESI, the EVPN control plane can build the candidate set of PEs that participate in that Ethernet Segment. This enables DF election for BUM forwarding and supports the correct interpretation of the segment's redundancy model. The incorrect statement is option C. The election algorithm itself is not the basic function of the route type 4 advertisement in the way the question frames it. The route type is primarily about Ethernet Segment discovery and participation; the algorithmic decision process is derived from configured DF election behavior and candidate information, not from route type 4 acting as a generic algorithm identifier. Therefore, route type 4 enables DF procedures, but it is not described as the mechanism that identifies the election algorithm type. Reference: EVPN RT-4 Ethernet Segment route, DF election, multi-homing discovery.
46. Frage
Which of the following statements about configuring and using an integrated routing and bridging (IRB) interface is TRUE?
Antwort: B
Begründung:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
An IRB interface is the logical connection point between a Layer 2 MAC-VRF and a Layer 3 IP-VRF. It provides the routed gateway function for hosts in the bridge domain while allowing traffic to move into the routed VRF for inter-subnet forwarding. The correct statement is that when an IRB sub-interface has multiple IP addresses, one can be designated as the primary. This is important because the primary address is used for normal gateway or subnet behavior when more than one address is present on the same routed interface context. Option A is inaccurate because the question is about an IRB sub-interface, not a generic subinterface selection between bridge or routed access modes. Option B is not the defining multi-homing model; EVPN multi-homing is implemented through Ethernet Segment association and MAC-VRF attachment behavior, not by adding multiple IRB subinterfaces for multi-homing. Option D is also wrong because the IRB is the shared logical link between the MAC-VRF and IP-VRF; the design does not require separate IRB subinterfaces on each side as independent constructs. Reference: SR Linux IRB configuration, MAC-VRF to IP-VRF interconnection, primary IP addressing.
47. Frage
Consider the exhibit.
All three leafs have an EVPN MP-BGP session with the route reflector in Spine-1. Leaf-2 and Leaf-3 have existing instances of an L2 EVPN named MAC VRF-1. Leaf-1 has just enabled a new instance of MAC VRF-1.
Which of the following steps is NOT taken when this new instance is enabled?
Antwort: B
Begründung:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
When a new Layer 2 EVPN MAC-VRF instance is enabled, the PE advertises an Inclusive Multicast Ethernet Tag route, commonly called an IMET route or EVPN route type 3. The IMET route is used to auto-discover remote PEs that participate in the same EVPN service and to build the BUM flooding list for that MAC-VRF. In this topology, all leaf routers peer with the route reflector on Spine-1. Leaf-1 therefore advertises its IMET route to the route reflector, not directly to Leaf-2 and Leaf-3. The route reflector then reflects the EVPN update to the other client leaves. Leaf-2 and Leaf-3 import the route based on matching route-target policy and add Leaf-1 to the replication list for broadcast, unknown unicast, and multicast traffic. Option B is the step that is not taken because it incorrectly describes direct leaf-to-leaf EVPN advertisement. In a route-reflector design, the RR centralizes EVPN route distribution and avoids the need for a full mesh of MP-BGP EVPN sessions between leaves. Reference: EVPN RT-3 IMET route, route-reflector operation, BUM flooding-list auto-discovery.
48. Frage
Which of the following statements describes the function or operation of the integrated gateway-based data center interconnect solution?
Antwort: C
Begründung:
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.
