350-001 · Question #90
Refer to the exhibit. When would the EEM applet be triggered?
The correct answer is C. every time that the input packet per second counter is above 10,000. An EEM applet using an interface threshold event with the 'above' operator fires each time the monitored counter exceeds the specified threshold value.

Why each option
An EEM applet using an interface threshold event with the 'above' operator fires each time the monitored counter exceeds the specified threshold value.
A trigger on values below 10,000 would require the 'lt' or 'below' operator, which is the opposite of what is configured.
Triggering on an increase of 1,000 would require a delta-based event type, not a static threshold comparison.
The EEM 'event interface' policy uses a threshold with a direction operator. When the operator is set to 'gt' or 'above' with a value of 10,000, the applet is triggered every time the input packets-per-second counter rises above 10,000, allowing automated responses to high-traffic conditions.
Triggering on a decrease of 1,000 would also require a delta-type event, and the direction would be downward rather than the configured upward threshold.
