The correct answers are A and B. In SRX chassis clustering, the fabric link, represented by fab interfaces, is the data-plane connection between the two cluster nodes. Juniper describes the fabric as the back-to-back data connection used when traffic on one node must be processed on the other node or must exit through an interface on the other node; session-state information also passes over the fabric. This is especially visible in active/active clustering, where ingress and egress interfaces can reside on different nodes and transit traffic must cross the fabric link.

Option B is also correct because the fabric link still exists in active/passive clustering for cluster data-plane synchronization and inter-node state handling, even though active/passive designs minimize fabric transit traffic because only one node normally forwards traffic at a time. Juniper specifically states that active/passive mode minimizes traffic over the fabric link, not that the fabric link is unused.

Options C and D are not the intended answers. The cluster is identified by a configured cluster ID, and each chassis is identified by a node ID, but the fabric interface names themselves are not where the cluster ID is reflected. Reference topics: HA Clustering, fabric link, active/active clustering, active/passive clustering, session synchronization, inter-node traffic.

The correct answer is C. Enable connectivity between the SRX Series device and Juniper ATP Cloud. Juniper ATP Cloud cannot inspect files, receive verdicts, or apply cloud-based malware intelligence until the SRX is enrolled and has a working secure connection to the ATP Cloud service. Juniper states that SRX enrollment establishes a secure connection between the SRX Series Firewall and the Juniper ATP Cloud server, downloads and installs certificate authorities, creates local certificates, enrolls them with the cloud server, and establishes the secure cloud connection.

Option A is not the first required configuration setting because the anti-malware service depends on successful cloud onboarding and connectivity. Option B is premature because firewall/security policies can reference malware inspection only after the device is properly connected and enrolled. Option D is also later in the workflow; anti-malware policies define how files are inspected and what action is taken, but those policies are useless if the SRX cannot communicate with ATP Cloud. Juniper also notes that ATP Cloud requires both the Routing Engine and Packet Forwarding Engine to reach the Internet, and DNS must resolve the cloud URL. Reference topics: ATP Cloud onboarding, SRX enrollment, advanced anti-malware connection, secure cloud connectivity, anti-malware policy deployment.

The correct answers are B and D. A terminal rule is specifically designed to stop further rule evaluation. Juniper states that the IDP rule-matching algorithm normally checks traffic against all matching rules in the rulebase, but when a terminal rule matches the source, destination, zones, and application, IDP does not continue to check subsequent rules for that same traffic. Juniper also warns that traffic matching a terminal rule is not compared to later rules even if it does not match the attack object inside that terminal rule.

Option D is also correct because the Ignore Connection action stops scanning traffic for the rest of the connection if an attack match is found. Juniper defines Ignore Connection as disabling the rulebase for that specific connection after a match. Option A is wrong because a close action closes the connection by sending reset behavior, but it is not the rule-processing control mechanism being tested. Option C is a trap: the exempt rulebase is used to suppress known false positives after an IPS rule match, but the two direct mechanisms that end IDP rule processing are terminal rule matching and ignore connection. Reference topics: IDP rulebases, terminal rules, Ignore Connection action, rule-matching algorithm, false-positive exemption.
