Which capability automatically identifies SaaS application performance metrics across WAN transports?

• A. VTP pruning
• B. Cloud onRamp
• C. BPDU Guard
• D. VRF leaking

Answer: (B)

Cloud OnRamp is the capability that automatically identifies SaaS application performance metrics across WAN transports. It detects SaaS traffic and continuously measures its performance as it traverses different links, whether MPLS, broadband Internet, or other WAN paths. By aggregating metrics like latency, jitter, and packet loss for these SaaS applications, it can steer traffic toward the most favorable path and, when appropriate, use direct Internet access to optimize user experience. This focused capability directly addresses cloud/SaaS performance across multiple transports, which is why it’s the best fit.

The other options relate to unrelated networking features: VTP pruning handles VLANs on switches, BPDU Guard protects against certain spanning-tree issues, and VRF leaking deals with routing isolation between VRFs. None of these identify or optimize SaaS performance across WAN transports.
