VoIP (Voice over IP) trafficishighly sensitive to network conditions, includinglatency, jitter, and packet loss. InPrisma SD-WAN, maintaining optimal VoIP quality requires dynamic path selection andreal-time monitoringof network conditions.
Recommended Initial Action: Monitoring Real-Time Path Performance MetricsWhen VoIP traffic experienceshigh latency and packet loss during business hours, the first step is toanalyze real-time path performance metricsinPrisma SD-WAN’s monitoring dashboard.
Identifies the Affected Links– Prisma SD-WAN continuously monitorspath quality metricsfor each available WAN link (e.g., MPLS, broadband, LTE).
Provides Insights on Congestion– Real-time monitoring helps determinewhether the issue is caused by congestion, ISP problems, or packet drops.
Aids in Dynamic Path Selection– Prisma SD-WAN can automatically switch to a better-performing path based on live telemetry data.
Avoids Unnecessary Configuration Changes– Without accurate diagnostics, changing VPN gateways or link tags may not address the root cause.
A. Configure a new VPN gateway connection.❌
Incorrect, because the issue isVoIP performance degradationdue tolatency and packet loss, not a VPN gateway failure.
A new VPN connectionwon’t resolve ongoing traffic congestionin the current SD-WAN path.
C. Add new link tags to existing interfaces.❌
Incorrect, because addingnew link tagsdoes notimmediately resolve latency and packet loss issues.
Link tags help classifyWAN links for application-aware routing, but the immediate priority is toanalyze performance metricsfirst.
D. Disable the most recently created path quality.❌
Incorrect, because disabling a path quality profilewithout understanding the causecould negatively impactfailover and traffic steeringpolicies.
Instead,monitoring real-time metrics firstensures the right corrective action is taken.
Firewall Deployment– Prisma SD-WAN is deployed alongside Palo Altofirewalls for network security and traffic steering.
Security Policies– Ensures VoIP traffic is prioritized withQoS and traffic shaping policies.
VPN Configurations– UsesIPsec tunnelsandDynamic Path Selection (DPS)for optimal WAN performance.
Threat Prevention– Detects and mitigates network-based attacks impactingVoIP performance.
WildFire Integration– Not directly related but helps detect malicious traffic within VoIP signaling.
Panorama– Centralized logging and monitoring ofSD-WAN path quality metricsacross multiple locations.
Zero Trust Architectures– Enforcesidentity-based access controlsfor secure VoIP communications.
Why Real-Time Monitoring is Crucial?Why Other Options Are Incorrect?References to Firewall Deployment and Security Features:Thus, the correct answer is:✅B. Monitor real-time path performance metrics.
