質問 # 29
Which of the following EVPN route-types is used to implement aliasing?
正解：A
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
Aliasing is an EVPN multi-homing mechanism that allows remote PEs to send traffic to any eligible PE attached to the same Ethernet Segment, even if a specific MAC address was learned and advertised by only one of those PEs. This avoids a traffic bottleneck and enables load-sharing in all-active multi-homing designs. The route type used to implement this behavior is the Ethernet Auto-Discovery per EVI route, commonly referred to as AD per EVI. This route tells remote PEs that a given PE has reachability to a specific Ethernet Segment for a specific EVPN instance. When remote PEs receive these advertisements from multiple PEs for the same ESI and EVI, they can treat those PEs as valid next-hops for traffic toward that Ethernet Segment. Ethernet Segment routes support ES discovery and DF election, while IP/MAC routes advertise host MAC and optionally IP binding information. AD per ES routes are used for broader Ethernet Segment-level procedures, but aliasing at the service level relies on AD per EVI reachability. Reference: EVPN route type 1, AD per EVI, aliasing in all-active multi-homing.

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?
正解：A
解説：
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.
質問 # 31
Which of the following statements does NOT describe the functionality or operation of the integrated gateway-based data center interconnect solution?
正解：B
解説：
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 solution, the data center gateway and WAN PE functions reside on the same router. This device acts as the interworking point between the data center EVPN/VXLAN environment and the WAN transport service. It may need to translate or interwork between VXLAN encapsulation in the data center and MPLS or another WAN tunneling protocol in the WAN. For Layer 3 services, the integrated gateway may also re-advertise EVPN routes learned from the data center fabric into VPN-IPv4 or VPN-IPv6 routes for transport across the WAN. Option B does not describe the integrated gateway model. A border leaf using eBGP or static routes to interconnect with a gateway is a decoupled gateway-based design, where the data center border leaf and WAN PE/gateway are separate devices with a routing handoff between them. In the integrated model, that border-leaf-to-separate-gateway handoff is not the defining architecture because the gateway and WAN PE roles are combined on one router. Reference: integrated gateway DCI, VXLAN-to-WAN interworking, EVPN to VPN-IPv4/VPN-IPv6 re-advertisement, decoupled gateway distinction.
質問 # 32
Consider the exhibit.
All IP-VRFs are configured properly and are operational.
Which of the following statements is FALSE?
正解：A
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In a single-active EVPN multi-homing design, the connected PE routers perform Designated Forwarder election to determine which PE is active for the relevant service or Ethernet Segment. The DF is responsible for forwarding toward the attached segment and, in a Layer 3 multi-homing case, only the active/DF PE advertises the customer IP prefix route toward the EVPN control plane. Single-active redundancy is communicated using Ethernet Segment-related EVPN procedures, including Ethernet A-D information, so remote PEs can identify the redundancy behavior and avoid forwarding traffic to an inactive attachment. The false statement is that the elected DF uses an AD per EVI update to identify itself as primary. AD per EVI is primarily used to advertise per-service Ethernet Segment reachability and support aliasing/load-balancing behavior in multi-homed services. DF election itself is driven by Ethernet Segment route procedures, not by the DF declaring itself primary through AD per EVI. Therefore, option B misstates the role of AD per EVI in the single-active L3 multi-homing control plane. Reference: EVPN DF election, single-active multi-homing, Ethernet A-D routes.
質問 # 33
Consider the exhibit.
The network is going to be designed to use interface-less symmetric routing.
Which of the following statements is TRUE?
正解：D
解説：
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.
