S5730-SI vs S5720-SI Advantages Comparison
Short answer
B BGP is supported by both S5720-SI and S5730-SI, so it is not an exclusive advantage of the S5730-SI.
Question
Key Takeaways
The trap lies in assuming all advanced features are new; BGP is shared, while hardware upgrades like fans and 40G interfaces are the true differentiators.
Learn why BGP is not an advantage of the Huawei S5730-SI over the S5720-SI. Discover key differences like pluggable fans, 40GE ports, and subcards.
Common mistake: Candidates often select options like '40 GE ports' or 'Subcard', thinking they might be incorrect due to complexity, but these are actual advantages of the S5730-SI.
Expert Analysis
The question asks to identify which feature is NOT an advantage of the S5730-SI compared to the S5720-SI. This requires comparing the specifications of these two Huawei switch models.
The S5730-SI series is a newer generation entry-level switch that offers several hardware and software advancements over the older S5720-SI. Specifically, the S5730-SI supports pluggable dual fans (Option A), which provides better redundancy and thermal management. It also supports subcards (Option D) and high-density 40GE ports via interface cards (Option C). These are all distinct advantages or features present in the S5730-SI but not typically found or available in the same capacity on the S5720-SI.
However, BGP (Border Gateway Protocol) support (Option B) is not an exclusive advantage. Both the S5720-SI and S5730-SI are Layer 3 switches that support dynamic routing protocols including BGP. Since both models support BGP, it is not a differentiating factor that makes the S5730-SI superior in this specific context. Therefore, BGP is the correct answer as it is not a unique advantage of the S5730-SI over the S5720-SI.
Comments confirm this reasoning, noting that BGP is common to both, while fans, 40G ports, and subcards are exclusive to the S5730-SI.

Exam Strategy
When comparing Huawei switch models, focus on physical layer enhancements (fans, power supplies, slots) and port density upgrades (10G/40G) as primary differentiators. Software features like routing protocols are often shared across generations unless specified as a new capability.
