Why this prevents config sync

BIG-IP device trust and config sync require closely synchronized system clocks. A time delta greater than 5 seconds between devices can break device trust, which in turn prevents config sync.

In the exhibit:

Time Delta to Local Device (sec): 12 ⟵ ❌ too large

This indicates an NTP/time synchronization issue between the devices.

Why the other options are incorrect

A. Next Active Load factor is 0
Load factors affect traffic distribution, not device trust or config sync.

B. Both devices are standby
Not shown in the output, and standby status does not block config sync.

C. Next Active Load factor is 1
Not shown and not relevant to config sync.
