Correct answer & explanation
Configure primary WAN and LTE interfaces
First, configure the primary WAN interface and the LTE backup interface. Then, create an IP SLA probe to monitor the primary link. Track the SLA with a tracking object. Set a static route with a higher metric for the LTE interface, tied to the track. When the primary fails, the track goes down, and the LTE route becomes active.

Variation 1. Drag and drop the steps of 4G/LTE WAN failover with IP SLA tracking into the correct order, from first to last.
medium- ✓ A.Configure IP SLA probe to monitor primary WAN
- ✓ B.Associate probe with tracking object
- ✓ C.Configure backup static route with higher metric for LTE
- ✓ D.Remove primary route when tracking object goes down
- ✓ E.Reroute traffic through LTE interface
Why A: For 4G/LTE WAN failover using IP SLA, first an IP SLA probe is configured to monitor the primary WAN link, then the probe is associated with a tracking object, a backup static route with a higher metric is configured for the LTE interface, the primary route is removed when the tracking object goes down, and finally traffic is rerouted through the LTE interface. The correct order is: configure IP SLA probe to monitor primary WAN, associate probe with tracking object, configure backup static route with higher metric for LTE, remove primary route when tracking object goes down, reroute traffic through LTE interface.
