質問 # 15
In EVPN, Type 5 routes are used only by hosts on a VXLAN network to access external networks.
正解：A
解説：
EVPN (Ethernet VPN) is a control plane technology used with VXLAN to provide Layer 2 and Layer 3 services in data center networks, including Huawei's implementations. EVPN routes are categorized into types, with Type 5 routes (IP Prefix routes) serving a specific purpose:
Type 5 Routes: These routes advertise IP prefixes and are used for inter-subnet routing, allowing communication between different VXLAN Virtual Network Identifiers (VNIs) or between VXLAN networks and external networks. They carry a Layer 3 VNI and IP prefix information, enabling routers or gateways to perform Layer 3 forwarding.
Usage Scope: Type 5 routes are not limited to hosts on a VXLAN network accessing external networks. They are also used by network devices (e.g., gateways, routers) within the EVPN domain to facilitate routing between subnets, including intra-VXLAN communication. For example, a centralized gateway or distributed gateway can use Type 5 routes to route traffic within the data center or to external networks, not just host-initiated access.
The statement is FALSE (B) because Type 5 routes are not exclusively for hosts on a VXLAN network to access external networks; they support broader Layer 3 routing functions across the EVPN domain.
質問 # 16
VXLAN is a network virtualization technology that uses MAC-in-UDP encapsulation. What is the destination port number used during UDP encapsulation?
正解：A
解説：
VXLAN (Virtual Extensible LAN) is a network overlay technology that encapsulates Layer 2 Ethernet frames within UDP packets to extend Layer 2 networks over Layer 3 infrastructure, widely used in Huawei's CloudFabric data center solutions. The encapsulation process, often referred to as "MAC-in-UDP," involves wrapping the original Ethernet frame (including MAC addresses) inside a UDP packet.
UDP Encapsulation: The VXLAN header follows the UDP header, and the destination UDP port number identifies VXLAN traffic. The Internet Assigned Numbers Authority (IANA) has officially assigned UDP port 4789 as the default destination port for VXLAN.
Options Analysis:
A). 4787: This is not a standard VXLAN port and is not recognized by IANA or Huawei documentation.
B). 4789: This is the correct and widely adopted destination port for VXLAN, as specified in RFC
7348 and implemented in Huawei's VXLAN configurations.
C). 4790: This port is not associated with VXLAN and is unused in this context.
D). 4788: This is not a standard VXLAN port; it may be confused with other protocols but is not correct for VXLAN.
Thus, the destination port number used during UDP encapsulation in VXLAN is B (4789), aligning with Huawei's VXLAN implementation standards.
質問 # 17
In an M-LAG, two CE series switches send M-LAG synchronization packets through the peer-link to synchronize information with each other in real time. Which of the following entries need to be included in the M-LAG synchronization packets to ensure that traffic forwarding is not affected if either device fails? (Select All that Apply)
正解：A、B
解説：
Multi-Chassis Link Aggregation Group (M-LAG) is a high-availability technology on Huawei CloudEngine (CE) series switches, where two switches appear as a single logical device to downstream devices. The peer-link between the M-LAG peers synchronizes critical information to ensure seamless failover if one device fails. Let's evaluate the entries:
A . MAC Address Entries: MAC address tables map device MACs to ports. In M-LAG, synchronizing MAC entries ensures that both switches know the location of connected devices. If one switch fails, the surviving switch can forward Layer 2 traffic without relearning MAC addresses, preventing disruptions. Required.
B . Routing Entries: Routing entries (e.g., OSPF or BGP routes) are maintained at Layer 3 and typically synchronized via routing protocols, not M-LAG peer-link packets. M-LAG operates at Layer 2, and while Layer 3 can be overlaid (e.g., with VXLAN), routing table synchronization is not a standard M-LAG requirement. Not Required.
C . IGMP Entries: IGMP (Internet Group Management Protocol) entries track multicast group memberships. While useful for multicast traffic, they are not critical for basic unicast traffic forwarding in M-LAG failover scenarios. Huawei documentation indicates IGMP synchronization is optional and context-specific, not mandatory for general traffic continuity. Not Required.
D . ARP Entries: ARP (Address Resolution Protocol) entries map IP addresses to MAC addresses, crucial for Layer 2/Layer 3 communication. Synchronizing ARP entries ensures the surviving switch can resolve IP-to-MAC mappings post-failover, avoiding ARP flooding or traffic loss. Required.
Thus, A (MAC address entries) and D (ARP entries) are essential for M-LAG synchronization to maintain traffic forwarding during failover, per Huawei CE switch M-LAG design.
質問 # 18
M-LAG configuration consistency check classifies device configurations into key configurations (Type 1) and common configurations (Type 2). This check can be performed in strict or loose mode based on the processing mode when key configurations are inconsistent. Which of the following statements is false about M-LAG configuration consistency check?
正解：D
解説：
If Type 2 configurations of the two M-LAG member devices are inconsistent, an alarm that indicates key and common configuration inconsistencies is generated. Evaluation: This statement is false. While Type 2 (common) configuration inconsistencies are detected during consistency checks, they do not typically trigger alarms, especially alarms that specifically indicate both key and common configuration inconsistencies. According to Huawei M- LAG Configuration Guide and Arista M-LAG Documentation, Type 2 inconsistencies may be logged or reported in system logs but are not severe enough to generate critical alarms unless they significantly impact network operation. Alarms are more commonly associated with Type 1 (key) configuration inconsistencies, as they pose a higher risk to M-LAG functionality.
質問 # 19
A VXLAN tunnel is identified by a pair of VTEP IP addresses. During VXLAN tunnel establishment, the local and remote VTEPs attempt to obtain each other's IP addresses. If the VTEP IP addresses are reachable to each other at Layer 3, a VXLAN tunnel can be established.
正解：A
解説：
VXLAN (Virtual Extensible LAN) tunnels are used to encapsulate Layer 2 traffic over a Layer 3 network, a key feature in Huawei's data center solutions. The endpoints of a VXLAN tunnel are VXLAN Tunnel Endpoints (VTEPs), identified by their IP addresses.
Tunnel Identification: A VXLAN tunnel is uniquely identified by the pair of VTEP IP addresses (local and remote), along with the VNI (VXLAN Network Identifier). This pair ensures the tunnel is specific to the communication path between the two VTEPs.
Tunnel Establishment: During setup, VTEPs exchange information to learn each other's IP addresses. This can occur manually (static configuration) or dynamically (e.g., via BGP EVPN).
The underlay network must provide Layer 3 reachability between the VTEP IP addresses, typically using routing protocols (e.g., OSPF, BGP) to ensure IP connectivity.
Reachability Condition: If the local and remote VTEP IP addresses are reachable at Layer 3, the tunnel can be established, allowing encapsulation and decapsulation of VXLAN traffic. This is a fundamental requirement in Huawei's VXLAN implementation.
The statement is TRUE (A) because a VXLAN tunnel's identification and establishment depend on reachable VTEP IP address pairs at Layer 3.
