Explanation:
Blank 1: A
Blank 2: D
Blank 3: C
Blank 4: B
The EEM applet monitors an interface parameter and triggers when the receive load crosses the configured threshold. The first missing value must be rxload because the applet is watching receive utilization on GigabitEthernet1/0. The second blank is entry-val 70, which defines the trigger threshold used with entry-op ge, meaning the event is triggered when the monitored value is greater than or equal to 70. After the event triggers, the CLI actions move into privileged mode, enter global configuration mode, and then must enter the target interface. Therefore, the next blank is int gig1/0. Once inside the interface, the script applies the access list with ip access-group important_traffic_ACL in, so the final snippet is ip access-group. This EEM workflow is an event-driven operational control: when utilization exceeds a threshold, the device applies a restrictive inbound ACL to preserve important traffic. The ENCOR concept is automation-based incident response using EEM, interface event detectors, and CLI actions.
