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

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?

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 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. What is causing this problem?

You notice that the secondary node of a chassis cluster has become disabled. What caused this

Users at a branch office report that they cannot reach an internal Web server. The users connect
through a single SRX Series device to reach the Web server. A security policy has been configured on
the device that allows traffic to flow between interfaces in the Trust zone. What is causing this
problem?

You are asked to troubleshoot a user communication problem. Users connected to the Trust zone
cannot communicate with other devices connected to the same zone. These users are able to
communicate with other devices in all other zones. How should you resolve this problem?

You have implemented AppTrack on your SRX Series device to track YouTube streaming video usage
in your network. However, many of the YouTube videos that your users are watching are shorter
than five minutes. You notice that the statistics for starting these short YouTube videos are not being
recorded by AppTrack. Which two actions would allow AppTrack to record the statistics for these
sessions? (Choose two.)

While attempting to set up IDP on an SRX Series device, the IDP attack database fails to download.
What is one reason for this behavior?

When attempting to delete IDP policies and configurations from an SRX Series device, a user enters
these configuration commands:
Delete security idp

Commit
However, after the commit has completed, the configuration is still present under the [edit security
