質問 # 22
Which of the following statements about PE-CE routing is FALSE?
正解：C
解説：
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.

質問 # 24
Which EVPN route-type (RT) is used in multi-homing scenarios to support aliasing and fast convergence?
正解：C
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
The EVPN route type used for aliasing and fast convergence in multi-homing is RT-1, the Ethernet Auto-Discovery route. RT-1 has two important forms: Ethernet A-D per Ethernet Segment and Ethernet A-D per EVI. These routes advertise reachability to a multi-homed Ethernet Segment and to a specific EVPN instance on that segment. Remote PEs use this information for aliasing, meaning they can forward traffic toward any eligible PE attached to the same Ethernet Segment, even when a specific MAC was advertised by only one PE. RT-1 also supports fast convergence because withdrawal of Ethernet A-D routes quickly informs remote PEs that an attachment path or PE is no longer valid, avoiding slow MAC aging as the primary failure-detection mechanism. RT-4 Ethernet Segment routes are related to multi-homing, but their main function is Ethernet Segment discovery and Designated Forwarder election. RT-2 advertises host MAC/IP reachability, and RT-3 builds multicast/BUM replication lists. Therefore, RT-1 is the precise answer for aliasing and fast convergence. Reference: EVPN multi-homing route types, Ethernet Auto-Discovery, aliasing and convergence behavior.
質問 # 25
Which of the following statements about the configuration of a distributed Layer 2 EVPN in a Nokia SR Linux 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]:
A distributed Layer 2 EVPN in SR Linux is implemented using MAC-VRF network instances, EVPN control-plane signaling, and VXLAN data-plane encapsulation. A common mistake is assuming that every PE must use the same EVI value for the same L2 service. In SR Linux, the important operational requirement is that the correct EVPN routes are imported and exported using matching route-target policy, not necessarily that every PE has the same locally configured EVI. Therefore, option A is false. The route distinguisher can be automatically generated using local values such as the autonomous system number and EVI, giving each PE's EVPN routes uniqueness in MP-BGP. A MAC-VRF is associated with VXLAN encapsulation for its data-plane service mapping, and route targets may need to be manually configured when leaf routers are in different autonomous systems because automatic derivation may not produce matching import/export policy across AS boundaries. The key separation is this: the RD gives uniqueness, the route target controls service membership, and the EVI is a local service identifier rather than a universal mandatory match in all designs. Reference: SR Linux distributed L2 EVPN configuration, EVI, RD auto-generation, route-target policy.
質問 # 26
Which of the following statements does NOT describe the functionality or operation of the integrated gateway-based data center interconnect solution?
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 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.
