質問 # 33
Which of the following statements about the decoupled gateway-based data center interconnect solution is TRUE?
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]:
A decoupled gateway-based DCI model separates the data center border-leaf function from the WAN PE function. This separation is the key design point. The border leaf remains part of the data center EVPN/VXLAN environment, while the WAN PE participates in WAN VPN transport and policy enforcement. Because the roles are split across two devices, the handoff between the border leaf and WAN PE provides a clean administrative and operational boundary. That boundary is useful for security policy, QoS marking, traffic classification, and troubleshooting ownership. The WAN does not need direct reachability to every leaf and route reflector as in a gateway-less model. The WAN PE also does not peer directly with the data center route reflector in a decoupled model; route exchange occurs through the border-leaf/WAN-PE handoff. VXLAN tunnels between leaf routers across different data centers are characteristic of gateway-less extension, not decoupled gateway operation. Therefore, the statement about clear demarcation between the data center border leaf and WAN PE is the accurate description. Reference: decoupled gateway-based DCI, security/QoS demarcation, WAN PE separation.
質問 # 34
Which EVPN route-type (RT) is used in multi-homing scenarios to support aliasing and fast convergence?
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]:
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fast convergence because withdrawal of Ethernet A-D routes quickly informs remote PEs that an attachment path or PE is no longer valid, avoiding slow MAC aging as the primary failure-detection mechanism.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 # 35
Consider the exhibit.
Which of the following statements about the proxy ARP entry for the neighbor IP 192.168.100.1 is FALSE?
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]:
Proxy ARP in a Layer 2 EVPN service allows the leaf to answer ARP requests locally using learned IP/MAC bindings, reducing broadcast flooding across the overlay. SR Linux can also monitor IP duplication and MAC/IP inconsistencies in the proxy ARP table. A pending state indicates that the system has detected suspicious or conflicting information and is monitoring the binding before declaring it duplicate. If the entry becomes duplicate, SR Linux can use a blackhole behavior to prevent forwarding traffic toward a conflicted endpoint, and a special discard MAC such as 00:00:00:00:DE:AD can be associated with the duplicate entry. Option D is false because it incorrectly states that all traffic destined to 192.168.100.1 will be discarded for exactly 9 minutes. The exhibit references monitoring and hold-down behavior, but the answer key rejects the fixed "9 minutes" traffic-discard statement. The key concept is that duplicate handling protects the EVPN service from unstable or conflicting IP/MAC bindings, but the specific discard duration in option D is not correct. Reference: proxy ARP, IP duplication monitoring, duplicate-state blackhole behavior.
質問 # 36
Which of the following statements about a distributed Layer 2 EVPN is FALSE?
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 a distributed Layer 2 EVPN service, the local leaf learns host reachability from frames received on access interfaces. When a host replies to an ARP request, the local leaf can learn the source MAC address from the Ethernet frame and install it in the MAC forwarding table. If the ARP payload contains an IP/MAC binding, the PE can also use that information for proxy ARP and EVPN MAC/IP advertisement. The local PE then advertises the learned endpoint reachability using EVPN route type 2 to its BGP EVPN peers or route reflector. The false statement is B. The ARP reply is not replicated to every leaf in the flooding list as a normal operation. EVPN's purpose is to reduce unnecessary flooding by distributing endpoint reachability through the control plane. BUM replication is used for broadcast, unknown unicast, and multicast traffic when needed, but a learned ARP reply does not require blind replication to all remote leaves. Instead, the leaf advertises the learned MAC/IP state through MP-BGP EVPN, allowing remote PEs to install accurate forwarding and proxy ARP state. Reference: distributed L2 EVPN operation, ARP learning, EVPN RT-2 advertisement.
質問 # 37
e-BGP is used as the routing protocol in the data center underlay.
When configuring the EVPN MP-BGP route reflector sessions, which of the following statements 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]:
In many SR Linux data center fabrics, eBGP is used in the underlay because it gives simple hop-by-hop routing, fast convergence, and clean autonomous-system separation between leaf and spine nodes. The EVPN overlay, however, is a separate MP-BGP control plane used to distribute EVPN NLRI. The overlay route-reflector session does not have to reuse the leaf's underlay autonomous system number. In practice, an overlay BGP group may use a distinct local AS or configuration model separate from the underlay AS design. Therefore, option B is false. The route reflector's cluster ID is configured on the route reflector itself to prevent reflection loops and identify the RR cluster. Redundant route reflectors can be deployed for resiliency, and clients may receive duplicate paths or duplicate updates from multiple RRs; the BGP decision process and route reflection rules handle this. The key design distinction is that underlay eBGP provides IP reachability between loopbacks, while overlay MP-BGP EVPN carries tenant service reachability. Mixing these roles leads to incorrect AS planning. Reference: SR Linux EVPN MP-BGP route reflectors, eBGP underlay, overlay BGP sessions.
