질문 # 43
Which of the following statements about utilizing asymmetric routing in an L3 EVPN network 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]:
Asymmetric routing relies heavily on host MAC/IP information because the ingress PE performs routing into the destination subnet and then sends the frame across the overlay using the destination MAC-VRF/VNI. This means PEs require enough ARP and MAC/IP binding information to forward traffic toward remote hosts correctly. If a host has multiple IP addresses on the same interface, separate EVPN route type 2 advertisements may be needed to communicate each IP-to-MAC binding. The ingress and egress PEs participate in MAC and IP forwarding across the end-to-end service path, but the forwarding responsibilities differ by direction and stage. The false statement is option C. The statement says all MAC-VRFs connected to the L3 EVPN network must exist on each PE, but that is not the correct requirement in this question's verified answer set. In practical EVPN designs, the exact MAC-VRF placement depends on whether the service is implemented as asymmetric, symmetric, interface-less, or interface-ful routing. Here, the course answer marks the universal MAC-VRF requirement as false. Reference: asymmetric L3 EVPN routing, RT-2 MAC/IP advertisements, ARP and MAC forwarding behavior.
질문 # 44
Which of the following statements about the Layer 2 EVPN configuration/operation in a Nokia SR Linux 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 SR Linux, a Layer 2 EVPN service is implemented using a MAC-VRF network instance. The MAC-VRF represents the tenant bridge domain and is associated with access subinterfaces and a VXLAN data-plane mapping. Local hosts are learned through the data plane when Ethernet frames arrive on local interfaces. Remote hosts, however, are not learned by flooding or by configuring static per-peer VXLAN interfaces. They are learned through MP-BGP EVPN updates, especially EVPN route type 2 MAC/IP Advertisement routes. Option B is false because SR Linux does not require a separate manually configured VXLAN interface toward each remote VTEP for the MAC-VRF. Instead, the MAC-VRF is bound to VXLAN encapsulation and a VNI, while remote VTEPs and their MAC reachability are discovered dynamically through the EVPN control plane. This is one of the central advantages of EVPN compared with static VXLAN flood-and-learn models: the overlay endpoints and endpoint reachability are signaled through BGP, reducing manual configuration and improving scale. Reference: SR Linux L2 EVPN MAC-VRF configuration, MP-BGP EVPN learning, VXLAN data-plane mapping.
질문 # 45
Which of the following EVPN route-types is used to implement aliasing?
정답：C
질문 # 46
Which of the following is NOT part of the description of a BGP route-distinguisher?
정답：B
설명：
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.
질문 # 47
Which of the following statements about utilizing VXLAN for the data plane in the data center 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]:
VXLAN provides a Layer 2 overlay over a Layer 3 underlay by encapsulating Ethernet frames in UDP/IP. This allows tenant bridge domains to span a routed IP fabric without requiring the underlay itself to behave like one large Layer 2 network. VXLAN uses a 24-bit VXLAN Network Identifier, which supports approximately 16 million logical overlays, far exceeding the scale of traditional 12-bit VLAN IDs. Because the VXLAN underlay is IP-routed, traffic can benefit from ECMP across equal-cost paths, improving fabric utilization and resiliency. The false statement is B. VXLAN was not originally developed specifically to support EVPN. VXLAN began as a data-plane overlay encapsulation technology, while EVPN later became the preferred control plane for distributing MAC, MAC/IP, multicast, and prefix reachability in VXLAN-based fabrics. In modern data center design, EVPN and VXLAN are commonly paired: VXLAN supplies the encapsulation and VNI-based segmentation, while EVPN supplies scalable control-plane learning and signaling. Reference: VXLAN data plane, EVPN control plane, ECMP underlay, VNI-based tenant isolation.
