A BIG-IP device shows its peer's trust status as 'untrusted' in the Configuration utility. What is the most likely cause?

The peer device is in standby mode.

The peer device is currently offline.

The peer device has a different software version.

The peer device was re-imaged or had its certificates regenerated, breaking the trust.

An administrator runs `tmsh show cm device` and sees the output: `Trust Status: trusted` for the peer. What does this indicate about the configuration synchronization?

The devices are in the same HA group.

The devices can securely synchronize configuration changes.

The devices cannot synchronize configuration changes.

A two-device sync-failover pair has device A active and device B standby. The trust status is 'trusted'. Suddenly, device A shows HA status 'offline' and device B becomes active. What is the most likely cause?

The trust relationship was broken, causing device A to go offline.

Device A was rebooted for maintenance, and device B took over.

Device B manually forced failover, causing device A to go offline.

Device A experienced a hardware failure or network outage, causing it to go offline and failover to device B.

A BIG-IP device in a sync-failover pair shows HA status 'active'. What does this indicate about the device's role?

The device is ready to take over traffic if the active device fails.

The device is currently processing traffic for the virtual servers.

The device is offline and not part of the HA pair.

The device is not processing traffic and is not ready to take over.

A two-device sync-failover pair has device A active and device B standby. The trust status is 'trusted'. Device A shows HA status 'active' and device B shows HA status 'standby'. What is the overall operational readiness of the pair?

The pair is in a split-brain condition and both devices are active.

The pair is fully operational with redundancy; failover will occur if device A fails.

The pair is operational but device B is not ready to take over.

The pair is operational but failover is not possible because trust is broken.
