SRX Series device chassis clusters are created by physically connecting two identical cluster-supported SRX Series devices using a pair of the same type of Ethernet connections. The connection is made for both a control link and a fabric (data) link between the two devices. The chassis cluster data plane is connected with revenue ports, which are the ports that carry user traffic. The chassis cluster can contain a maximum of two devices, as only two nodes can form a cluster. The chassis cluster data plane is not connected with SPC ports, which are the ports that provide services processing. The chassis cluster cannot contain more than two devices, as this would violate the cluster design. References: Chassis Cluster Overview, Connecting SRX Series Firewalls to Create a Chassis Cluster

Juniper ATP Cloud is a cloud-based service that provides advanced threat prevention for SRX Series devices. Juniper ATP Cloud can inspect files for malware by sending them to the cloud or performing a hash lookup. To reduce delays in the inspection of files, Juniper ATP Cloud performs the following two functions12:

• Juniper ATP Cloud allows the creation of allowlists. Allowlists are lists of trusted files or domains that are not sent to the cloud for inspection. This reduces the network traffic and the processing time for the files that are known to be safe. You can create allowlists from the Juniper ATP Cloud Web UI or the SRX Series device CLI.
• Juniper ATP Cloud performs a cache lookup on files. Cache lookup is a feature that checks if a file has been previously scanned by Juniper ATP Cloud and returns the cached verdict. This avoids sending the same file to the cloud again and saves bandwidth and time. Cache lookup is enabled by default and can be configured from the SRX Series device CLI. References:
