질문 # 47
Leaf routers are configured to support Layer 2 multi-homing all-active mode.
Which of the following statements is FALSE?
정답：D
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
For Layer 2 all-active EVPN multi-homing on SR Linux, the Ethernet Segment configuration is the control-plane anchor that binds the redundant access attachment to EVPN. The relevant LAG subinterfaces must be associated with the Ethernet Segment so that the PE can advertise the segment correctly and apply split-horizon and aliasing behavior. The Ethernet Segment must also be administratively enabled; otherwise, the PE will not participate properly in ES discovery and DF procedures. The multi-homing mode must be set to all-active to permit forwarding through multiple attached leaf routers and support host-side LAG operation. The false statement is option B. The Ethernet Segment Identifier has a defined structure, and the blanket statement that the 2nd through 7th octets "must not be all zeros" is not a valid requirement as stated. What matters operationally is that the ESI uniquely identifies the same multi-homed Ethernet Segment across participating PEs and is consistently configured where required. The ESI must be non-zero as a meaningful segment identifier, but the specific octet restriction in the option is not the SR Linux all-active configuration rule. Reference: SR Linux L2 EVPN all-active multi-homing, Ethernet Segment configuration, LAG association.
질문 # 48
Which of the following statements about a BGP route target is FALSE?
정답：C
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
A BGP route target is an extended community used to control which EVPN routes are imported into which MAC-VRF or IP-VRF. It is carried with EVPN updates and acts as the import/export policy tag for tenant service membership. The statement that it is a BGP extended community is correct. It is also correct that route targets support multi-tenant operation, because they allow different EVPN instances to carry potentially overlapping MAC or IP information while importing only the routes intended for that service. However, option D is false in the wording used here. The route target does not itself identify the EVPN instance in the control plane as a unique route identifier. That role is more closely associated with the route distinguisher and EVPN NLRI construction, while the route target determines import eligibility. A route target tells a receiving PE whether the route belongs in a local service instance, but it is not the unique identity of the EVPN route. This distinction is critical: route distinguishers make routes unique; route targets control route distribution and service membership. Reference: EVPN route targets, BGP extended communities, route import/export policy, RD versus RT function.
질문 # 49
Consider the exhibit.
Which of the following statements is FALSE?
정답：B
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In an SR Linux Layer 2 EVPN MAC-VRF, locally attached MAC addresses are learned through the data plane on local access interfaces, while remote MAC addresses are learned from MP-BGP EVPN control-plane advertisements and installed with a VXLAN next-hop. The exhibit shows one local learned MAC on an Ethernet subinterface and another MAC learned through EVPN with a VXLAN interface and VNI 100. The remote VTEP or next-hop information identifies the remote endpoint, and the VNI maps the received VXLAN traffic to the correct MAC-VRF service. The false statement is C because saying that the MAC address associated with the vxlan-interface "will not age out" is too absolute. A remote EVPN MAC is not aged in the same way as a local data-plane-learned MAC, but it can still be removed when the corresponding EVPN route is withdrawn, invalidated, or no longer present in the control plane. The "N/A" style aging behavior does not mean permanent retention. Reference: SR Linux MAC-VRF verification, local MAC learning, EVPN-learned remote MACs, VXLAN VNI mapping.
질문 # 50
Which of the following statements about a L3 EVPN network using symmetric routing is FALSE?
정답：C
설명：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
Symmetric L3 EVPN routing uses an IP-VRF-based overlay model in which both ingress and egress PEs participate in routed forwarding. The ingress PE receives the frame from the local MAC-VRF, routes it into the IP-VRF, and sends it across the VXLAN routed interface. The egress PE receives the routed overlay packet, performs the corresponding IP-VRF lookup, and then forwards it into the locally attached destination MAC-VRF. Because the routed overlay is built per IP-VRF, a routed-VXLAN interface is required for that IP-VRF. EVPN route type 5 support is also required because RT-5 carries IP prefix reachability across the EVPN control plane. The false statement is option D. Symmetric routing specifically removes the requirement for every MAC-VRF to exist on every PE. A PE only needs the MAC-VRFs for locally attached subnets, plus the shared IP-VRF and routed overlay state. This is the major scaling advantage of symmetric routing compared with designs that require broad MAC-VRF instantiation across the fabric. Reference: symmetric L3 EVPN routing, routed VXLAN interface, RT-5 prefix reachability, MAC-VRF scaling.
질문 # 51
Consider the exhibit.
Which of the following statements about the proxy ARP entry for the neighbor IP 192.168.100.1 is FALSE?
정답：C
설명：
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.
