To defend againstapplication-layer DDoS attacks, Huawei'sAntiDDoSproduct is the most suitable choice.Key details about the options:

HiSec Insight:A security analytics platform for threat detection and response, but not specifically designed for DDoS mitigation.

USG6000E:A next-generation firewall with basic DDoS protection, but limited in handling large-scale or sophisticated attacks.

AntiDDoS:A dedicated solution for detecting and mitigating DDoS attacks, including application-layer attacks like HTTP floods.

FireHunter:A sandboxing solution for advanced threat detection, not DDoS defense.

TheAntiDDoSproduct excels in identifying and mitigating application-layer attacks by analyzing traffic patterns and applying granular mitigation policies.

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.
