質問 # 76
To allow access to a VXLAN network, you need to configure service access points on devices.
There are two access modes: Layer ? sub-interface and binding. (Enter the acronym in uppercase letters.)
正解：
解説：
3
Explanation:
VXLAN (Virtual Extensible LAN) is a network overlay technology that extends Layer 2 networks over a Layer 3 underlay, commonly implemented in Huawei's CloudFabric data center solutions.
To enable access to a VXLAN network, service access points (e.g., interfaces or sub-interfaces) must be configured on devices such as switches or routers acting as VXLAN Tunnel Endpoints (VTEPs). The question mentions two access modes: "Layer ? sub-interface" and "binding," with the task to fill in the layer acronym in uppercase letters.
Context Analysis: The missing layer is indicated by a "?" and is part of a sub-interface configuration. In networking, sub-interfaces are typically associated with Layer 3 (e.g., for VLAN tagging or VXLAN integration), where they handle IP routing or mapping to overlay networks.
Access Modes:
Layer 3 Sub-Interface: This mode involves configuring a sub-interface on a Layer 3 device (e.g., a router or Layer 3 switch) to terminate VXLAN tunnels and perform routing. The sub-interface is associated with a VNI (VXLAN Network Identifier) and often uses a Layer 3 protocol (e.g., BGP EVPN) to connect to the VXLAN overlay.
Binding: This likely refers to binding a VNI to a Bridge Domain (BD) or interface, a common practice in Huawei's VXLAN configuration to map the overlay network to a physical or logical port.
This can occur at Layer 2 or Layer 3, but the sub-interface context suggests Layer 3 involvement.
The question's structure implies the layer number for the sub-interface mode, which is Layer 3 in VXLAN contexts for routing and gateway functions. Thus, the acronym (digit) to enter is 3.
質問 # 77
Which of the following can be deployed to enhance DC reliability? (Select All that Apply)
正解：B、C、D
解説：
Reliability in Huawei's CloudFabric data centers is enhanced through various mechanisms. Let's evaluate each option:
A). Power supply redundancy: This is true. Redundant power supplies (e.g., dual PSUs) ensure uninterrupted operation during power failures, a key reliability feature. TRUE.
B). M-LAG (Multi-Chassis Link Aggregation): This is true. M-LAG provides high availability by allowing active-active forwarding and failover between switches, enhancing network reliability.
TRUE.
C). Monitor Link: This is false. Monitor Link is a Huawei feature for link status monitoring, not a direct reliability enhancement mechanism like redundancy or clustering. FALSE.
D). Controller cluster: This is true. A clustered SDN controller (e.g., iMaster NCE-Fabric) ensures high availability and failover, improving network management reliability. TRUE.
Thus, A, B, and D enhance DC reliability.
質問 # 78
Which of the following is not an advantage of link aggregation on CE series switches?
正解：D
解説：
Link aggregation, often implemented using Link Aggregation Control Protocol (LACP) on Huawei CloudEngine (CE) series switches, combines multiple physical links into a single logical link to enhance network performance and resilience. The primary advantages include:
Load Balancing Supported (B): Link aggregation distributes traffic across multiple links based on hashing algorithms (e.g., source/destination IP or MAC), improving load distribution and preventing any single link from becoming a bottleneck.
Increased Bandwidth (C): By aggregating multiple links (e.g., 1 Gbps ports into a 4 Gbps logical link), the total available bandwidth increases proportionally to the number of links.
Improved Reliability (D): If one link fails, traffic is automatically redistributed to the remaining links, ensuring continuous connectivity and high availability.
However, Improved Forwarding Performance of Switches (A) is not a direct advantage.
Forwarding performance relates to the switch's internal packet processing capabilities (e.g., ASIC performance, forwarding table size), which link aggregation does not inherently enhance. While it optimizes link utilization, it doesn't improve the switch's intrinsic forwarding rate or reduce latency at the hardware level. This aligns with Huawei's CE series switch documentation, where link aggregation is described as enhancing bandwidth and reliability, not the switch's core forwarding engine.
質問 # 79
Which of the following statements is false about the routing design for the underlay network during DCN deployment?
正解：A
解説：
The underlay network in Huawei's DCNs (e.g., CloudFabric) uses routing protocols like OSPF or BGP. Let's evaluate each statement:
A). OSPF is recommended for small and midsize DCNs, and EBGP is recommended for large and midsize networks: This is true. OSPF suits smaller networks (<300 switches), while EBGP is better for large networks (>300 switches) due to scalability. TRUE.
B). When OSPF is used on the underlay network, only single-area OSPF can be deployed: This is false. Multi-area OSPF can be deployed to manage larger networks, reducing routing table size and improving stability, a common practice in Huawei DCNs. FALSE.
C). Compared with OSPF, EBGP involves fewer calculations and offers better scalability: This is true. EBGP's path-vector nature requires fewer computational resources than OSPF's link-state calculations and scales better with large topologies. TRUE.
D). When EBGP is used on the underlay network, each group of active-active leaf nodes is deployed in an AS: This is true. In EBGP designs, active-active leaf nodes (e.g., M-LAG) are typically in the same Autonomous System (AS) to simplify routing, using iBGP or route reflectors.
TRUE.
Thus, B is the false statement because multi-area OSPF is supported, not just single-area.
質問 # 80
Both M-LAG and stacking technologies can overcome the disadvantages of traditional DCNs. However, M-LAG is a better choice to ensure 24/7 service continuity.
正解：B
解説：
Traditional data center networks (DCNs) often suffer from single points of failure, limited scalability, and traffic bottlenecks. Both M-LAG and stacking address these issues, but their suitability for 24/7 service continuity differs.
M-LAG Benefits: M-LAG (Multi-Chassis Link Aggregation) on Huawei CE switches allows two devices to act as a single logical switch, providing active-active forwarding, high availability, and rapid failover (e.g., via peer-link synchronization). It supports non-stop service during device failures, making it ideal for 24/7 continuity.
Stacking Benefits: Stacking combines multiple switches into a single logical unit, sharing a control plane. While it improves scalability and simplifies management, a stack master failure can disrupt the entire stack unless redundancy is perfectly configured, potentially affecting service continuity.
Comparison: M-LAG's decentralized design and real-time synchronization offer better fault isolation and recovery compared to stacking, where a master switch failure impacts the stack. Huawei documentation highlights M-LAG's superiority for high-availability scenarios like 24/7 operations.
The statement is TRUE (A) because M-LAG is indeed a better choice than stacking for ensuring 24/7 service continuity due to its robust failover and redundancy features.
