NEW QUESTION # 20
Which of the following EVPN route-types is used to implement aliasing?
Answer: C
NEW QUESTION # 21
Consider the exhibit.
All connected leaf routers have the same Ethernet segment configuration. The IP-VRF is configured properly and is 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]:
The exhibit describes a Layer 3 multi-homing scenario where the Ethernet Segment is associated with an IP-VRF and the configuration references an EVI value of 1000. The segment is configured with all-active multi-homing, allowing multiple attached leaf routers to advertise reachability for the same external L3 next-hop or third-party prefix attachment. In this model, the Ethernet Segment represents the shared L3 attachment and is used by EVPN to associate remote prefix reachability with the multi-homed segment. The incorrect statement is that a LAG must be configured on the connected leaf routers and the host. That requirement is specific to many Layer 2 all-active host attachment designs, where the host commonly uses LACP toward multiple leaf routers and the leaf LAG subinterfaces are associated with the Ethernet Segment. In Layer 3 multi-homing, the attached device can be a router or VNF, and the EVPN ES association can be used for L3 prefix reachability without mandating that the host side be configured as a LAG. Reference: L3 EVPN multi-homing, EVI association, all-active Ethernet Segment behavior.
NEW QUESTION # 22
Which of the following statements about EVPN PE-CE routing, using BGP as the routing protocol, 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 EVPN PE-CE routing, the PE exchanges ordinary IPv4 or IPv6 unicast routing information with the CE. When the PE learns CE prefixes, it imports them into the tenant IP-VRF and advertises them to other EVPN PEs as EVPN route type 5 IP Prefix routes. Conversely, when the PE receives EVPN routes from remote PEs, it can advertise corresponding IPv4/IPv6 BGP updates toward the CE, subject to policy. Import and export policies are essential because they control which customer routes are accepted, which EVPN-learned routes are advertised, and how attributes are modified. Option C is false because iBGP is not the preferred PE-CE model in this context. eBGP is typically preferred between PE and CE because it creates a clean administrative routing boundary between the provider/data-center edge and the customer or external router. Using eBGP also simplifies route policy, loop prevention, and operational separation. The CE does not need to participate in the EVPN overlay; it speaks standard BGP unicast with the PE, while the PE performs the EVPN RT-5 advertisement into the fabric. Reference: EVPN PE-CE BGP routing, eBGP preference, RT-5 prefix advertisement, import/export policy.
NEW QUESTION # 23
Leaf routers are configured to support Layer 2 multi-homing all-active mode.
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 all-active Layer 2 EVPN multi-homing, the host is typically dual-homed to two or more leaf routers using a LAG. The participating leaf routers must configure the LAG and associate it with the Ethernet Segment so EVPN can advertise the common ESI and apply aliasing, split-horizon, and DF procedures. If VLAN tagging is used for service separation, tagging must be configured on the LAG interface so that the correct subinterfaces can bind into the MAC-VRF and Ethernet Segment. Option C is false because it states that the LACP system-id-mac must uniquely identify each leaf router. In an all-active EVPN multihomed LAG, the opposite principle applies: from the host's LACP perspective, the multihomed leaf pair must appear as a single logical LACP system. That generally requires a shared LACP system ID or coordinated system MAC behavior across the participating PEs. If each leaf presented a unique LACP system identity, the host would treat them as separate LAG partners and the all-active bundle would not form correctly. Reference: all-active L2 EVPN multi-homing, LAG attachment, LACP system ID behavior, Ethernet Segment association.
NEW QUESTION # 24
Consider the exhibit.
The network is going to be designed to use interface-less symmetric routing.
Which of the following statements is TRUE?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In interface-less symmetric routing, the EVPN fabric exchanges host forwarding information using EVPN route type 2 MAC/IP advertisements. RT-2 carries the host MAC address and, when present, the associated host IP address, allowing remote PEs to build the forwarding state needed for distributed gateway operation. Unlike asymmetric routing, interface-less symmetric routing does not require every MAC-VRF to be instantiated on every PE. The design scales better because each leaf only needs the locally attached MAC-VRFs plus the shared IP-VRF/routed VXLAN construct for inter-subnet forwarding. Option B describes an asymmetric forwarding pattern more than a symmetric one; in symmetric routing, both ingress and egress PEs perform routed forwarding functions through the IP-VRF. Option C is also incorrect because anycast gateway is fundamental when multiple leaves provide the same default-gateway service for a subnet. Therefore, the true statement is that forwarding information is exchanged using EVPN route type 2 updates. Reference: interface-less symmetric routing, EVPN RT-2 host MAC/IP signaling, distributed IRB operation.
