300-415 Question 51
Single answerAn organization is deploying Cisco SD-WAN Cloud OnRamp for SaaS to optimize application performance across multiple cloud-hosted services. During the deployment, they want to ensure that the SD-WAN solution dynamically selects the best-performing path to each SaaS application based on real-time metrics. Which feature of Cisco SD-WAN Cloud OnRamp enables this functionality?
- A
Application-Aware Routing
- B
Direct Internet Access (DIA)
- C
SaaS Probing
- D
Cloud Gateway Redundancy
Show answer and explanation
Correct answer: C
Explanation
Cisco SD-WAN Cloud OnRamp for SaaS uses the SaaS Probing feature to evaluate the performance of different paths to SaaS applications in real time. By continuously monitoring metrics like latency, loss, and jitter, SaaS Probing enables the SD-WAN solution to dynamically select the optimal path, ensuring the best possible application performance for end users.
- A. Incorrect.
Application-Aware Routing is used to make routing decisions based on application policies and performance metrics, but it is not specifically responsible for dynamically selecting the best-performing path for SaaS applications in Cloud OnRamp.
- B. Incorrect.
Direct Internet Access (DIA) allows branches to access internet resources directly without backhauling traffic through the data center, but it does not handle the dynamic selection of paths to SaaS applications.
- C. Correct.
SaaS Probing is a key feature of Cisco SD-WAN Cloud OnRamp that continuously monitors the performance of multiple paths to SaaS applications and dynamically selects the best-performing path based on real-time metrics.
- D. Incorrect.
Cloud Gateway Redundancy ensures high availability and failover for cloud gateways, but it does not optimize SaaS application performance by dynamically selecting paths.
