Why each option

The FortiGate has entered system conserve mode, which by default triggers the blocking of new sessions to manage resource consumption.

AFortiGate generated an event log for system conserve mode.

While entering conserve mode generates an event log, the statement implies the output *is* the log generation itself, rather than confirming the mode and its actions.

BFortiGate has entered in to system conserve mode.Correct

When the FortiGate's memory usage crosses defined thresholds, it enters conserve mode to protect system stability, as indicated by output like 'Entering conserve mode'.

CBy default, the FortiGate blocks new sessions.Correct

A primary action of FortiGate conserve mode is to block new sessions by default, which prevents further memory allocation and allows existing sessions to complete gracefully.

DFortiGate changed the global av-failopen settings to idledrop.

System conserve mode manages memory and session resources but does not automatically change the global antivirus fail-open settings.
