S5720-SI vs S5720-LI Feature Comparison
Short answer
A 32k MAC entries are supported by both S5720-LI and S5720-SI, so they are not an advantage of SI over LI.
Question
Key Takeaways
The trap is assuming all listed features are superior in the SI; however, MAC table size is identical in both, while routing and redundancy differ.
This page explains why 32k MAC entries are not an advantage of the S5720-SI over the S5720-LI, as both models share this capacity.
Common mistake: Selecting OSPF or BGP because candidates forget the LI is L2-only, or selecting Dual Power because they assume LI has no redundancy options.
Expert Analysis
The question asks to identify which feature is NOT an advantage of the Huawei S5720-SI over the S5720-LI. This requires comparing the feature sets of these two specific switch series.
First, consider Layer 3 routing capabilities. The S5720-LI is a Layer 2-only switch, meaning it does not support dynamic routing protocols like OSPF or BGP. The S5720-SI is a Layer 3 switch that supports both OSPF and BGP. Therefore, having OSPF (Option B) and BGP (Option D) are distinct advantages of the SI model over the LI model.
Next, examine hardware redundancy. The S5720-LI typically comes with a fixed power supply configuration without modular redundancy options in its standard form factor. In contrast, many S5720-SI models offer optional dual power modules for high availability. Thus, dual power module support (Option C) is an advantage of the SI.
Finally, look at MAC address table capacity. Both the S5720-LI and S5720-SI series generally support up to 32k MAC entries in their respective configurations. Since this capability is present in both models, it is not a differentiating advantage of the SI over the LI. As noted in community feedback, this is a shared specification rather than a unique benefit of the higher-tier SI model.
Therefore, the correct answer is A, as it is the only option listed that is not an exclusive advantage of the S5720-SI compared to the S5720-Li.
Exam Strategy
When comparing Huawei switch tiers, always verify if a feature is exclusive to the higher tier or shared across multiple tiers. For example, know that LI switches lack Layer 3 routing (OSPF/BGP), making those SI advantages, but check base specs like MAC tables which may be identical.
