You are having problems establishing an IPsec tunnel between two SRX Series devices.
What are two explanations for this problem? (Choose two.)
Answer : AC
Incorrect:
B, D: Antivirus and TCP MSS clamping has no relation to IPSec tunnels.
Two SRX Series devices are having problems establishing an IPsec VPN session. One of the devices has a firewall filter applied to its gateway interface that rejects UDP traffic.
What would resolve the problem?
Answer : D
UDP port 500 is used by IKE.
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?
Answer : B
You want to allow remote users using PCs running Windows 7 to access the network using an IPsec VPN. You implement a route-based hub-and-spoke VPN; however, users report that they are not able to access the network.
