You have configured the custom attack signature shown in the exhibit. This configuration is valid, but you want to improve the efficiency and performance of your IDP.
Which two commands should you use? (Choose two.)

Your company is using a dynamic VPN configuration on their SRX device. Your manager asks you to enforce password expiration policies for all VPN users.
Which authentication method meets the requirement?

You have just committed the new IDP policy shown in the exhibit. However, you notice no action is taken on traffic matching the R4 IDP rule.
Which two actions will resolve the problem? (Choose two.)

HostA (1.1.1.1) is sending TCP traffic to HostB (2.2.2.2). You need to capture the TCP packets locally on the SRX240. Which configuration would you use to enable this capture?

You have already configured a hub-and-spoke VPN with one hub device and two spoke devices. However, the hub device has one neighbor in the Init state and one neighbor in the Full state.
What would you do to resolve this problem?

You are asked to troubleshoot ongoing problems with IPsec tunnels and security policy processing. Your network consists of SRX240s and SRX5600s.
Regarding this scenario, which two statements are true? (Choose two.)

You are asked to design a solution to verify IPsec peer reachability with data path forwarding.
Which feature would meet the design requirements?

You have a group IPsec VPN established with a single key server and five client devices.
Regarding this scenario, which statement is correct?

A new server has been set up in your environment. The administrator suspects that the firewall is blocking the traffic from the new server. Previously existing servers in the VLAN are working correctly. After reviewing the logs, you do not see any traffic for the new server.
Referring to the exhibit, what is the cause of the problem?

You are attempting to establish an IPsec VPN between two SRX devices. However, there is another device between the SRX devices that does not pass traffic that is using UDP port 4500.
How would you resolve this problem?

An SRX Series device is configured for inline tap mode.
What will occur if Drop Packet is selected?
