JN0-335 Exam Questions Tutorials

SRX does not identify the iot device. It streams the metadata to Juniper ATP cloud and Junipe ATP cloud identifies the device.

 SSL proxy is a transparent proxy that performs SSL encryption and decryption between the client and the server. It allows inspection of encrypted traffic by terminating the SSL connection from either end and applying security policies to the clear text. SSL proxy can leverage pre-match or post-match results to determine whether to apply SSL proxy to a session. Pre-match results are based on the initial packet of the session, while post-match results are based on the application identification after the session is established. In the exhibit, the session shows that the application services identification is “ssl-proxy”, which means that SSL proxy is applied based on the pre-match results. The cache lookup status for application services is “on”, which means that the SRX Series device uses the application system cache to store the pre-match results for faster processing. Therefore, the correct answer is D. SSL proxy leverages pre-match result. References: = SSL Proxy, Configuring SSL Proxy, and Application System Cache

The infected host cloud feed is a list of IP addresses that have been identified as compromised or infected by malware. The feed is updated by Juniper ATP Cloud based on the detection of malicious activity from the hosts, such as contacting known command-and-control servers. When a host on the network reaches the configured threat level threshold, its IP address is automatically added to the infected host cloud feed and blocked from communicating with any other hosts on the Internet. The other feeds are not relevant for this situation. The command-and-control cloud feed is a list of IP addresses that are known to be used by malware for remote control and communication. The allowlist and blocklist feed is a user-defined list of IP addresses that are either allowed or denied by the SRX Series device. The custom cloud feed is a user-defined list of IP addresses that are associated with a specific category or threat level. References:
