Troubleshooting

Which log file on the ION device provides the most detailed information about WAN interface flapping?

You notice an ION device is showing as 'Disconnected' in the Controller UI. What is the first step you should take?

When analyzing a PCAP from an ION device, you see 'ICMP Destination Unreachable'. Which policy is most likely causing this?

A specific branch is failing to steer traffic via the preferred ISP despite a defined Path Policy. What is the most likely cause?

A branch site reports intermittent application slowness. Which tool in the Prisma SD-WAN ION dashboard is best for viewing real-time latency and jitter metrics per path?

A site has two ISPs. Traffic is only using one. What is the best way to verify if both paths are available?

What does the 'Flow Monitor' tool primarily track?

Where do you view the history of configuration changes pushed to an ION device?

An ION device has experienced a configuration drift. How can you restore the last known good configuration?

Which feature should you examine if traffic is not being steered based on the application category?

When troubleshooting a site-to-site VPN issue between two ION devices, which status should you check first?

A user is complaining about high latency for a SaaS app. The Path Quality dashboard shows low latency. What is the next logical step?

A user reports that a specific SaaS application is being blocked, but no security policy matches are seen. What is the most likely cause?

When troubleshooting QoS, what does a high 'drop' count in the interface statistics imply?

What information is provided by the 'Controller Status' widget on the dashboard?

You are debugging a routing loop. Which tool can you use to see the BGP route advertisements received by an ION device?

Which log is used to view denied traffic attempts?

You need to see the exact DSCP markings on packets exiting the ION. Which tool should you use?

If an ION device is not receiving DHCP addresses from an upstream provider, where should you look first?

A branch is failing to load-balance traffic across two ISPs. Both are active. Which setting controls the load-balancing algorithm?

A user reports slow speeds. You see that the interface is not hitting the configured throughput limit. What could be the issue?

What is the function of the 'Reachability' check in the ION device configuration?

Which dashboard is most useful for identifying top bandwidth consumers in the network?

A branch loses connectivity to the internet, but local LAN traffic is fine. What should you troubleshoot first?

Which mechanism would explain why traffic is taking a sub-optimal path despite a policy favoring a different link?
