You are asked to set up an IPsec tunnel to the destination 192.168.103.2. After applying the configuration, you notice in the show security ike security-associations output that the destination stays in a down state.
Referring to exhibit, what is causing the problem?

Your SRX Series device has the following configuration:
user@host> show security policies
...
Policy: my-policy, State: enabled, Index: 5, Sequence number: 1
Source addresses: any Destination addresses: any
Applications: snmp
Action: reject
From zone: trust, To zone: untrust
...
When traffic matches my-policy, you want the device to silently drop the traffic; however, you notice that the device is replying with ICMP unreachable messages instead.
What is causing this behavior?

You are having problems establishing an IPsec tunnel between two SRX Series devices.
What are two explanations for this problem? (Choose two.)
