Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inside the junos-icmp application object definition.
Why it's wrong here
Application objects define match criteria for security policies, not routing engine access.
- ✗
Inside the global SCREEN option profile under ICMP flood settings.
Why it's wrong here
SCREEN options drop or alert on ICMP, they do not permit inbound control access.
- ✓
Under the security zone host-inbound-traffic system-services icmp configuration.
Why this is correct
Host-inbound traffic settings permit system services like ping/icmp to reach the routing engine.
- ✗
Under the security policies between the untrust and trust zones.
Why it's wrong here
Transit policies apply to traffic passing through the SRX, not traffic terminating on the routing engine itself.
