Option A:In traditional IP routing, each router in the network must maintain a routing table that contains network-wide routes or at least the routes relevant to its operation. This ensures that packets can be forwarded correctly to their destination.

Option B:Traditional IP routing operates on the principle of the "longest match rule." When a router receives a packet, it examines the destination IP address and matches it against the entries in its routing table. The longest prefix match determines the next hop for the packet.

Option C:Traditional IP networks are inherently connectionless, meaning there is no dedicated path established between the source and destination before data transmission. This lack of connection-oriented mechanisms makes it challenging to guarantee Quality of Service (QoS) across the entire network.

Option D:In traditional IP networks, packets are forwarded using a hop-by-hop mechanism. Each router along the path decapsulates the packet, inspects its headers, and forwards it to the next hop based on its routing table.

The statement is incorrect because IP addresses function at the network layer (Layer 3) of the OSI model, not the data link layer (Layer 2). At the data link layer, devices useMAC addresses(Media Access Control addresses) to identify each other. MAC addresses are unique identifiers assigned to network adapters and are defined by the IEEE 802 standard.While IP addresses are essential for routing data across networks, they are not directly related to the data link layer. Therefore, the claim that "the address that functions at the data link layer is called an IP address" is false.

The transition to all-Ethernet data center networks is driven by several IT transformations. Below is an analysis of each option:

PCIe is replaced : PCIe is a local bus standard used for high-speed device connections within servers. Its replacement does not directly contribute to the shift toward all-Ethernet networks.

Storage media evolves from HDDs to SSDs : The adoption of SSDs increases storage performance and reduces latency, making Ethernet-based storage protocols like NVMe over Fabrics (NVMe-oF) viable alternatives to traditional Fibre Channel.

The IT architecture evolves from centralized to distributed : Distributed architectures require scalable and flexible networking solutions, which Ethernet-based networks are well-suited to provide.

The deployment mode evolves from single-cloud mode to multiple deployment modes such as multi-cloud mode : While multi-cloud deployments influence network design, they do not directly drive the shift to all-Ethernet networks.

Thus, the correct answers are B and C .

Overview of Huawei CloudCampus 3.0:

Huawei CloudCampus 3.0 is designed to provide a fully-wireless, intelligent, and cloud-based campus network solution. It focuses on improving efficiency, reducing costs, and enabling digital transformation.

Analyzing Each Option:

Option A:"One global network: 40% lower private line costs" is correct. Huawei CloudCampus 3.0 reduces private line costs by leveraging cloud-based technologies and SD-WAN solutions.

Option B:"L3 autonomous driving: 90% fewer complaints" is correct. The solution uses AI-driven automation to minimize network issues and improve user satisfaction.

Option C:"Low-carbon intelligence: 60% smaller energy consumption of the entire network" isnot correct. While Huawei emphasizes energy efficiency, the claim of a 60% reduction in energy consumption is exaggerated and not supported by official documentation.

Option D:"Fully-wireless experience: 40% higher productivity" is correct. The fully-wireless architecture enhances user experience and productivity.

Conclusion:The incorrect benefit description is Option C.

Understanding Hardware-Based BFD:

Bidirectional Forwarding Detection (BFD) is a protocol used to detect faults in network paths quickly. Hardware-based BFD offloads processing to dedicated chips, enabling faster detection intervals.

Huawei CE6863E-48S6CQ Capabilities:

TheCE6863E-48S6CQswitch supports hardware-based BFD with aminimum packet sending interval of 3.3 ms, ensuring rapid fault detection and recovery.

Conclusion:The statement is TRUE because the CE6863E-48S6CQ supports hardware-based BFD with the specified interval.

While Huawei'sUSG series firewallsinclude basicanti-DDoS capabilities, they are not designed to completely replace standaloneanti-DDoS products. Firewalls primarily focus on access control, threat prevention, and policy enforcement, whereas dedicated anti-DDoS solutions offer advanced features like large-scale traffic scrubbing, anomaly detection, and mitigation for massive DDoSattacks.For environments facing sophisticated or volumetric DDoS threats, standalone anti-DDoS appliances or cloud-based services are recommended to complement firewall capabilities.

Huawei'sCloudWAN solutiontargets several key government WAN scenarios and market opportunities:

Dedicated networks for cities:Provides connectivity for smart city initiatives, including public safety, transportation, and utilities.

National broadband network:Supports nationwide broadband infrastructure for government services and citizens.

Dedicated networks for provinces:Enables regional connectivity for provincial governments and agencies.

Dedicated networks for ministries:Serves specific government departments like MOI, MOE, MOF, and MOD, ensuring secure and reliable communication.

Asset management networkis not a typical WAN scenario but rather a subset of IoT or enterprise applications, making it irrelevant in this context.

A WLAN (Wireless Local Area Network) is specifically defined as a network that uses radio frequency (RF) technologies , primarily Wi-Fi, to provide wireless connectivity. While technologies like infrared, Bluetooth, and ZigBee are wireless communication methods, they are not part of the WLAN definition.

Wi-Fi : Operates in the 2.4 GHz and 5 GHz frequency bands and is the primary technology used in WLANs.

Infrared : Uses light waves for short-range communication and is not part of WLAN standards.

Bluetooth : Designed for short-range personal area networks (PANs), not LANs.

ZigBee : Used for low-power, low-data-rate IoT applications, not WLANs.

Thus, the statement is FALSE , as WLANs are exclusively based on RF technologies like Wi-Fi.
