質問 # 51
The continuous development and innovation of upper-layer services pose higher requirements on general-purpose computing data center networks. Which of the following requirements can be met by deploying M-LAG and Eth-Trunk? (Choose all that apply.)
正解：A、B、C
解説：
M-LAG improves network device redundancy and ensures service continuity in case of device or link failures, which directly supports high availability. Eth-Trunk aggregates multiple physical links into one logical link, increasing total transmission capacity and providing higher aggregated bandwidth. Together, M-LAG and Eth-Trunk also support seamless Layer 2 mobility and VM migration by maintaining consistent forwarding across dual-homed connections in data center environments. Elastic scalability is more related to architecture expansion and cloud resource elasticity rather than directly provided by M-LAG or Eth-Trunk mechanisms.

PC1 and PC2 are connected to the same switch, but they cannot learn each other's ARP information. This may be caused by incorrect VLAN configuration on the switch.
正解：B
解説：
This statement is true . ARP is a Layer 2 broadcast-based protocol used to resolve an IPv4 address into a MAC address within the same broadcast domain. If two PCs are connected to the same switch but cannot learn each other's ARP entries, one likely reason is an incorrect VLAN configuration .
For example, if PC1 and PC2 are placed in different VLANs, or if one interface is configured with the wrong access VLAN, ARP broadcast frames from one PC will not reach the other PC because VLANs separate Layer 2 broadcast domains. As a result, the ARP request will not be received by the peer, and the MAC address cannot be resolved. Other causes may also exist, such as incorrect IP addressing, port isolation, or security policies, but VLAN misconfiguration is a very common and valid cause in campus switching scenarios. HCIA-Datacom teaches that ARP communication depends on correct Layer 2 domain membership, and VLAN planning or interface configuration errors often directly affect host-to-host communication even when both hosts are physically connected to the same switch.

Drag and Drop Question
On a general-purpose computing data center network, network administrators need to use various network technologies or architectures to ensure high network stability and efficiency.
Match the following network technologies or architectures with the requirements they meet.
正解：
解説：
Explanation:
M-LAG → High availability
Spine-Leaf → Scalability
VXLAN → User isolation
M-LAG provides device-level and link-level redundancy, ensuring services continue running even if a link or device fails, which directly improves high availability. Spine-Leaf is a scalable data center architecture designed to allow easy horizontal expansion with predictable performance as the network grows. VXLAN enables network virtualization by isolating tenant networks over a shared physical infrastructure, supporting strong user or tenant isolation.
質問 # 54
UDP does not guarantee data transmission reliability and does not provide packet sorting and traffic control functions. It is suitable for the traffic that has low requirements for data transmission reliability, but high requirements for the transmission speed and delay.
正解：B
解説：
UDP (User Datagram Protocol) is a connectionless protocol that does not provide reliability, packet sequencing, or traffic control. These features are usually managed by TCP, which is used for applications requiring reliable data transmission. UDP's design makes it suitable for real-time applications, such as video streaming or VoIP, where speed and low latency are prioritized over reliability.
質問 # 55
Huawei network devices support multiple types of storage devices. After the administrator enters the save command in the user view of a switch, the current configuration file is saved to the SDRAM. After the switch restarts, the configuration file still takes effect.
正解：A
解説：
On Huawei switches, the active configuration is stored in SDRAM during operation, but SDRAM is volatile memory. The save command writes the configuration to non-volatile storage (such as NVRAM/flash), not to SDRAM. This is what allows the configuration to persist after a restart.
