Which of the following switches does not support two power modules?
- A. S5732-H
- B. S5735-L
- C. S5736-S24T4XC
- D. S5731-S24P4X
Answer: B
Explanation:
The Huawei CloudEngine S5735-L series switches are entry-level switches designed for small to medium- sized networks. These switches do not support dual power modules , as they are intended for environments where redundancy is not a primary requirement.
In contrast:
* The S5732-H, S5731-S24P4X, and S5736-S24T4XC switches all support dual power modules, providing redundancy and ensuring stable operation in more demanding environments.
Thus, the switch that does not support two power modules is the S5735-L .

NEW QUESTION # 45
The attack principle of 226.SYN-FLOOD is to forge a SYN message with a source address and send it to the victim host. After the victim host replies SYN-ACK messages to these addresses, it will not receive ACK messages, causing the victim host to maintain a large number of semi- connections until timeout. These half-connections can exhaust host resources and prevent the victim host from establishing a normal TCP connection, thereby achieving the purpose of the attack.
- A. False
- B. True
Answer: B

NEW QUESTION # 47
Which of the following networking models are supported in Huawei's SD-WAN solution?
- A. Hierarchical networking
- B. Intelligent HQoS
- C. Partial-mesh networking
- D. Hub-spoke networking
- E. Full-mesh networking
Answer: A,C,D,E
Explanation:
Huawei'sSD-WAN solutionsupports multiple networking models to meet diverse enterprise requirements:
* Hub-spoke networking:Centralizes traffic through a hub site, ideal for security and policy enforcement.
* Hierarchical networking:Organizes sites into tiers (e.g., regional hubs and branches), enabling scalable architectures.
* Partial-mesh networking:Connects critical sites directly while routing other traffic through hubs, balancing performance and cost.
* Full-mesh networking:Provides direct connections between all sites, ensuring optimal performance for latency-sensitive applications.
Intelligent HQoSis not a networking model but rather a feature that enhances Quality of Service (QoS) across any of these models.
