NEW QUESTION # 19
Which of the following EVPN route-types is used to implement aliasing?
Answer: B
NEW QUESTION # 20
Consider the exhibit.
The network is configured for interface-less symmetric routing with an ECMP of 4 enabled on all leaf routers.
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 interface-less symmetric L3 EVPN routing, hosts in a subnet may be attached to different leaf routers, while inter-subnet forwarding is performed through the IP-VRF using VXLAN routed interfaces. The ingress and egress PEs both participate in L3 forwarding, and the routed VXLAN interface provides the per-IP-VRF overlay data-plane construct needed for symmetric routing. The IRB interfaces on the local MAC-VRFs must advertise learned local host routes so that remote PEs have the necessary host reachability information. The MAC-VRFs also need the appropriate EVPN control-plane configuration so host MAC/IP information can be exchanged, while the IP-VRF participates in L3 VPN-style route exchange for routed reachability. Option A is false because anycast gateway is not optional in this design for Leaf1 and Leaf2. Anycast gateway allows the same default-gateway IP and virtual MAC behavior to exist consistently on multiple leaves serving the same subnet. Without it, host default-gateway behavior would be inconsistent and traffic mobility across the fabric would break expected distributed gateway operation. Reference: interface-less symmetric routing, IRB, anycast gateway, routed VXLAN interface.
NEW QUESTION # 21
Consider the exhibit.
The two MAC-VRFs are inter-connected using IP-VRF3 which is to be deployed using asymmetric routing.
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 asymmetric L3 EVPN routing, each participating PE must have the MAC-VRFs needed to forward traffic in the destination bridge domain. However, the specific exhibit describes two MAC-VRFs interconnected through IP-VRF3, with Leaf-1 hosting MAC-VRF1 and Leaf-2 hosting MAC-VRF2. The false statement is that Leaf-1 and Leaf-2 must both have instances of MAC-VRF1 and MAC-VRF2. That requirement is not true for this described deployment. Each local MAC-VRF connects to IP-VRF3 using an IRB interface, and host MAC/IP information is advertised using EVPN route type 2 so remote PEs can learn endpoint reachability. The question's answer also implies that IP prefix advertisement using route type 5 is part of the control-plane exchange between the leaves for the routed service context. What matters is that the fabric can resolve host and prefix reachability through EVPN without forcing every PE to instantiate every MAC-VRF in this topology. Option B overstates the MAC-VRF placement requirement and is therefore false. Reference: asymmetric L3 EVPN routing, RT-2 host advertisements, RT-5 IP prefix routes, IRB attachment.
NEW QUESTION # 22
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.
NEW QUESTION # 23
Which of the following is NOT part of the description of a BGP route-distinguisher?
Answer: B
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
A route distinguisher is used in MP-BGP VPN and EVPN address families to make otherwise overlapping tenant routes unique in the BGP control plane. In EVPN, different tenants or EVPN instances may legitimately use the same MAC or IP values. The route distinguisher makes the NLRI globally unique by prepending a unique value to the tenant route. It is typically unique per PE and per EVI, and it is carried in EVPN route advertisements. However, the route distinguisher does not control route import, export, or service membership. That role belongs to the route target, which is a BGP extended community used by receiving PEs to decide which EVPN instance should import the route. Therefore, option D is not part of the correct description of a route distinguisher. Saying that the RD identifies the EVPN instance in the control plane confuses RD uniqueness with route-target membership. The RD makes routes unique; the route target associates those routes with the appropriate MAC-VRF or IP-VRF import policy. Reference: EVPN route distinguisher, overlapping tenant addresses, route target separation.
