300-415 Question #280: Real Exam Question with Answer & Explanation

Question

Options

• AConfigure a policy named 'app-visibility' under Localized Policy.
• BConfigure Data Policy with options for Application Firewall, QoS, Traffic Engineering, or Custom.
• CConfigure a policy with 'sla-class Gols', 'latency', 'loss', 'jitter', and 'app-route-policy' parameters.
• DConfigure a Cflowd Policy named 'AAR' with specific timeout and sampling intervals.

Explanation

To discover, monitor, and track applications running on a WAN Edge device on the LAN, an 'app-visibility' policy must be configured under Localized Policy.

Common mistakes.

• B. Configuring Data Policy with options like Application Firewall, QoS, Traffic Engineering, or Custom primarily focuses on controlling traffic flow and security based on applications, not specifically on enabling the discovery and monitoring of applications themselves.
• C. A policy with sla-class Gols, latency, loss, jitter, and app-route-policy parameters is used for Application-Aware Routing (AAR) to direct traffic based on performance, not for discovering and monitoring applications.
• D. While Cflowd is used for flow monitoring, configuring a Cflowd Policy named 'AAR' is for flow export and analysis, but the app-visibility localized policy is the explicit command that enables the necessary DPI and cflowd on the WAN Edge for application discovery and monitoring.
