NEW QUESTION # 43
Consider the exhibit.
Which of the following statements about the configuration and operation of this setup 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]:
This setup represents single-active Layer 2 EVPN multi-homing. In single-active mode, the Ethernet Segment is configured so that only one PE acts as the active forwarding node for a given service, while the other remains standby. The ports connecting to the host are associated with ES-1 so the EVPN control plane can perform Ethernet Segment discovery, DF election, and standby behavior. If Leaf1 is the active/DF node for the service, all traffic to and from the host flows through Leaf1 until a failure or DF transition occurs. Option D is false because a host LAG is not required for this single-active topology. A LAG is typically required for all-active L2 multi-homing, where the host must treat multiple physical links toward different leaf routers as one logical bundle. In single-active operation, the host can be connected through separate physical links or active/standby access behavior without requiring LACP bundling. The EVPN PEs enforce the active path selection through DF and ES state rather than relying on host-side LAG hashing. Reference: single-active EVPN multi-homing, Ethernet Segment port association, DF-controlled active forwarding.
NEW QUESTION # 44
Which of the following statements about utilizing asymmetric routing in an L3 EVPN network 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]:
Asymmetric routing relies heavily on host MAC/IP information because the ingress PE performs routing into the destination subnet and then sends the frame across the overlay using the destination MAC-VRF/VNI. This means PEs require enough ARP and MAC/IP binding information to forward traffic toward remote hosts correctly. If a host has multiple IP addresses on the same interface, separate EVPN route type 2 advertisements may be needed to communicate each IP-to-MAC binding. The ingress and egress PEs participate in MAC and IP forwarding across the end-to-end service path, but the forwarding responsibilities differ by direction and stage. The false statement is option C. The statement says all MAC-VRFs connected to the L3 EVPN network must exist on each PE, but that is not the correct requirement in this question's verified answer set. In practical EVPN designs, the exact MAC-VRF placement depends on whether the service is implemented as asymmetric, symmetric, interface-less, or interface-ful routing. Here, the course answer marks the universal MAC-VRF requirement as false. Reference: asymmetric L3 EVPN routing, RT-2 MAC/IP advertisements, ARP and MAC forwarding behavior.
NEW QUESTION # 45
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?
Answer: C
Explanation:
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.
NEW QUESTION # 46
Which of the following EVPN route-types is used to implement aliasing?
Answer: D
NEW QUESTION # 47
Which of the following statements about PE-CE routing is FALSE?
Answer: D
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
PE-CE routing is the mechanism used to exchange customer prefix reachability between a provider edge or data center leaf and the attached customer edge router. It can be implemented statically or dynamically. Static routing is operationally simple but does not scale well when many prefixes or frequent changes are involved. BGP is preferred for larger deployments because it supports policy, route filtering, attributes, and automated advertisement of changing reachability. In most EVPN PE-CE designs, eBGP is preferred because it creates a clean routing boundary between the PE and CE, with each device operating in a different autonomous system. Option D is false because the CE does not advertise BGP EVPN route type 5 updates to the PE. The CE advertises ordinary IPv4 or IPv6 unicast prefixes over the PE-CE routing session. The PE then imports those customer prefixes into the IP-VRF and advertises them into the EVPN overlay as route type 5 IP Prefix routes toward other PEs. This distinction matters: EVPN signaling is a PE-to-PE overlay function, not a CE-originated EVPN control-plane role. Reference: PE-CE routing, eBGP, EVPN RT-5 prefix advertisement.
