The two correct statements when performing this task are A.
BGP FlowSpec is used to collect traffic flows from Junos OS devices, and C.
Statistical sampling decreases event correlation accuracy.
BGP FlowSpec is a Junos OS feature that allows network devices to send traffic flow information to a Juniper security device using BGP.
This allows the Juniper security device to monitor and collect the traffic flows and analyze them for suspicious activity.
Statistical sampling increases processor utilization by selecting only a subset of the data to be analyzed, which can help reduce the amount of data sent to the security device.
However, this also decreases the accuracy of event correlation, as some events may be missed due to the sampling. Superflows reduce traffic licensing requirements by offloading the processing of certain traffic flows to the device itself, instead of having it sent to the security device.

JIMS server is a Juniper Identity Management Service that collects user identity information from different authentication sources for SRX Series devices. It can connect to SRX Series devices and CSO platform in your network.
JIMS server is a service that protects corporate resources by authenticating and restricting user access based on roles. It connects to SRX Series devices and CSO platform to provide identity information for firewall policies. To reduce the load that JIMS server places on your network, you should connect JIMS to another SRX Series device. This way, you can distribute the identity information among multiple SRX Series devices and reduce network traffic.

The two tasks that must be completed before a configuration for IPS on an SRX Series device will work are downloading the IPS signature database and installing the IPS signature database. The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to download and install the IPS signature database. Enrolling the SRX Series device with Juniper ATP Cloud is not necessary to make a configuration work, and rebooting the SRX Series device is not required either.

Based on SSL proxy is a feature that allows SRX Series devices to decrypt and inspect SSL/TLS traffic for security purposes. According to SRX Series devices support two types of SSL proxy:
Client-protection SSL proxy also known as forward proxy - The SRX Series device resides between the internal client and outside server. It decrypts and inspects traffic from internal users to the web.
Server-protection SSL proxy also known as reverse proxy - The SRX Series device resides between outside clients and internal servers. It decrypts and inspects traffic from web users to internal servers.

Infected hosts are internal hosts that have been compromised by malware and are communicating with external C&C servers3. Juniper ATP Cloud provides infected host feeds that list internal IP addresses or subnets of infected hosts along with a threat level3. Once the Juniper ATP Cloud global threshold for an infected host is met, that host is added to the infected host feed and assigned a threat level of 10 by the cloud4. You can also configure your SRX Series device to block traffic from these IP addresses using security policies4.
