SRX Series devices have a maximum of how many rollback configurations?
Screens on an SRX Series device protect against which two types of threats? (Choose two.)
ICMP flood
Use the ICMP flood IDS option to protect against ICMP flood attacks. An ICMP flood attack typically occurs when ICMP echo requests use all resources in responding, such that valid network traffic can no longer be processed.
The threshold value defines the number of ICMP packets per second (pps) allowed to be send to the same destination address before the device rejects further ICMP packets.
IP spoofing
Use the IP address spoofing IDS option to prevent spoofing attacks. IP spoofing occurs when an invalid source address is inserted in the packet header to make the packet appear to come from a trusted source.
Which two statements are correct about the default behavior on SRX Series devices? (Choose two.)
SRX Series devices have a maximum of how many rollback configurations?
You have configured a UTM feature profile.
Which two additional configuration steps are required for your UTM feature profile to take effect? (Choose two.)
For the UTM feature profile to take effect, it must be associated with a security policy and a UTM policy. The security policy defines the traffic flow and the actions that should be taken on the traffic, while the UTM policy defines the security features to be applied to the traffic, such as antivirus, intrusion prevention, and web filtering. The UTM feature profile provides the necessary configuration for the security features defined in the UTM policy.
