During troubleshooting, an engineer needs to capture traffic between two sites to see if packets are being dropped. Which diagnostic tool is most appropriate for this task?

Packet capture on the SD-WAN devices

SNMP polling of interface counters

Syslog messages from the firewall

During troubleshooting, an engineer sees that the tunnel status is 'down' but the physical link is up. What does this indicate?

The tunnel is operational but not carrying traffic

The tunnel is in a standby state and will become active when needed

The physical link is the cause of the issue

The tunnel is not operational, likely due to a configuration or negotiation issue

A branch site reports that it can reach the internet but cannot reach the corporate data center. You verify the SD-WAN tunnel status and see that the primary tunnel is 'down' and the secondary tunnel is 'up'. What should you do NEXT to restore connectivity?

Reboot the branch appliance to force a re-establishment of the primary tunnel.

Check the configuration of the secondary tunnel to ensure it is carrying the correct traffic and that routing is updated.

Immediately open a ticket with the ISP to investigate the primary tunnel's failure.

Disable the secondary tunnel to force all traffic over the primary tunnel.

A user at a branch site cannot reach a server at the data center. You run a traceroute from the user's workstation and see that the traffic stops at the branch appliance's LAN interface. What does this MOST likely indicate?

The branch appliance is not forwarding the traffic to the data center.

The server at the data center is down.

The user's workstation has a misconfigured IP address.

An engineer is troubleshooting a site-to-site connectivity issue and needs to gather diagnostic data. Which set of data would provide the most comprehensive view of the problem?

Only the interface statistics from the hub site

Only the routing table from the remote site

Logs, packet captures, and tunnel status information

Only the SD-WAN path quality metrics
