The correct answers are A and B. In SRX chassis clustering, the fab interface is the fabric data-plane link between cluster nodes. Juniper explains that data-plane software synchronizes session state using runtime objects, or RTOs, across the fabric data link, and this fabric link also supports forwarding traffic between nodes when ingress and egress processing occur on different chassis members.
swfab is also a chassis-cluster data-plane-related interface used for Layer 2 switching fabric functionality.
Juniper's Ethernet switching on chassis cluster documentation describes swfab0 and swfab1 as pseudointerfaces created for Layer 2 fabric functionality, enabling switching across the nodes. Option C, fxp1, is wrong because fxp1 is the control link interface used for cluster control-plane communication, heartbeats, and synchronization signaling, not a data-plane fabric interface. Option D, fxp0, is wrong because fxp0 is the out-of-band management interface. The clean separation is: fxp0 = management, fxp1 = control link, fab = routed/data fabric, and swfab = Layer 2 switching fabric.

The correct answers are A and C. In an SRX chassis cluster, redundant Ethernet interfaces are configured as reth interfaces. Juniper defines a reth interface as a pseudointerface that includes at least one physical interface from each node in the cluster. Therefore, assigning a physical interface from node0 and a physical interface from node1 to the same reth interface is mandatory for redundant Ethernet operation. Juniper also states that before configuring chassis cluster redundant Ethernet interfaces, you must set the number of redundant Ethernet interfaces.
Option C maps to the required reth-count configuration under the chassis cluster hierarchy. Without defining the number of reth interfaces, Junos does not know how many redundant Ethernet pseudointerfaces are available for the cluster configuration. Option B is wrong because setting a retry interval is not a required step for creating a reth interface or redundancy group. Option D is wrong because heartbeat behavior belongs to cluster control-link monitoring and chassis-cluster node health, not to the required configuration steps for Ethernet reth membership. The required design steps are: define reth capacity, create/configure the reth interface, assign child physical links from both nodes, and associate the reth with the proper redundancy group. Reference topics: HA Clustering, redundant Ethernet interfaces, reth-count, reth child interfaces, redundancy groups.

The correct answers are B, D, and E. Security Director device onboarding depends on management reachability and valid administrative access. Juniper's device discovery documentation states that Junos Space discovers network devices using SSH, with optional ping and SNMP, and connects to the physical device to retrieve running configuration and status information. It also explains that device authentication uses administrator login credentials, SSH credentials, SNMP settings, or keys depending on the discovery method.
Option E is required because Security Director must target a reachable management IP address or hostname.
Juniper's discovery-profile workflow explicitly uses the target IP address, hostname, IP range, or subnet to locate devices. Option D is required because invalid username/password or insufficient privileges prevent discovery and management; Juniper's device-management guidance identifies credentials as required input for discovering devices. Option B is required because onboarding uses SSH, so the correct SSH service and port must be reachable. Juniper's device access procedure explicitly includes a Port field for the SSH connection.
Option A is wrong because chassis serial number is not the normal troubleshooting field for Security Director discovery. Option C is wrong because active security policies do not determine whether Security Director can initially discover and onboard the device. Reference topics: Security Director, device discovery, SSH access, management IP reachability, authentication credentials.

The correct answers are C and D. The cSRX is Juniper's containerized SRX firewall, intended for lightweight virtual and container environments where rapid deployment and high density matter. Juniper's cSRX documentation lists supported security capabilities including basic firewall policy, NAT, Intrusion Detection and Prevention, content security/UTM functions, ATP Cloud, SSL Proxy, AppID, AppFW, and AppTrack.
That supports option C, because cSRX provides SRX security services in a containerized footprint rather than requiring a full VM-based firewall appliance.
Option D is also correct because Juniper identifies the cSRX's small footprint and minimum resource reservation requirements as key benefits; it is designed to scale more densely than VM-based firewall options.
Juniper's Day One cSRX guide specifically identifies faster deployment, a small footprint, and reduced resource consumption as major benefits. Option A is not the best answer for this exam item because the question asks for cSRX deployment benefits, not merely forwarding-mode support. Option B is wrong because the tested cSRX advantage is not a default three-zone configuration. Reference topics: cSRX container firewall, virtual SRX deployment, firewall/NAT/IPS/UTM services, lightweight resource footprint.

The correct answers are A and C. Juniper ATP Cloud uses a malware-analysis pipeline. When a file is submitted, the first step is a cache lookup based on the file hash. Juniper explains that if the file has already been analyzed, the stored verdict is returned to the SRX Series Firewall and there is no need to re-analyze the file. That directly supports C and eliminates B, because analysis does not continue when a cached verdict is found.
If the cache lookup does not return a verdict, the remaining ATP Cloud analysis techniques are used. Juniper describes the pipeline model in which each analysis technique creates a verdict number, and those verdicts are combined into a final verdict score from 0 to 10. That final threat score is what the SRX compares against ATP Cloud policy settings to permit or block the session.
Option D is wrong because ATP Cloud does not simply return the first score generated by any one feature.
The expected behavior is cumulative/final scoring across the remaining analysis pipeline. Reference topics:
