Juniper JN0-335 Exam Dumps

The fab interface is a fabric link that connects the two nodes in a chassis cluster. A chassis cluster is a high-availability feature that groups two identical SRX Series devices into a cluster that acts as a single device. The fab interface has two functions:

Real-time objects (RTOs) are exchanged on the fab interface to maintain session synchronization: RTOs are data structures that store information about active sessions, such as source and destination IP addresses, ports, protocols, and security policies. RTOs are exchanged between the nodes on the fab interface to ensure that both nodes have the same session information and can take over the traffic in case of a failover.

In an active/active configuration, inter-chassis transit traffic is sent over the fab interface: In an active/active configuration, both nodes in a cluster can process traffic for different redundancy groups (RGs). RGs are collections of interfaces or services that fail over together from one node to another. If traffic needs to transit from one RG to another RG that is active on a different node, it is sent over the fab interface.

If your JIMS server is unable to view event logs, two actions that you would take to solve this issue are:

Enable remote event log management within Windows Firewall on the necessary Exchange servers: JIMS (Juniper Identity Management Service) is a Windows service that collects user, device, and group information from Active Directory domains or syslog sources and provides it to SRX Series devices for identity-based security policies. JIMS relies on the event logs generated by the domain controllers and Exchange servers to track user logins, logouts, and IP address changes. If the Windows Firewall on the Exchange servers blocks the remote event log management, JIMS cannot access the event logs and obtain the user identity information. Therefore, you need to enable remote event log management within Windows Firewall on the Exchange servers that are configured as event sources in JIMS.

Enable remote event log management within Windows Firewall on the necessary domain controllers: Similarly, if the Windows Firewall on the domain controllers blocks the remote event log management, JIMS cannot access the event logs and obtain the user identity information. Therefore, you need to enable remote event log management within Windows Firewall on the domain controllers that are configured as event sources in JIMS.

According to the Juniper Networks JNCIS-SEC Study Guide, when you set up your command-and-control (C&C) category with Juniper ATP Cloud, all of the feeds will initially have zero objects in them. This is normal, as it can take a few minutes for the feeds to download. No action is required in this scenario and you will notice the feeds start to populate with objects once the download is complete.

The exhibit shows a configuration snippet for security intelligence on an SRX Series device. Security intelligence is a feature that allows you to block or monitor traffic from malicious sources based on threat intelligence feeds from Juniper ATP Cloud or other providers. The configuration defines a profile for ATP Infected-Hosts, which is a feed that contains IP addresses of hosts that are infected with malware and communicate with command-and-control servers. The configuration also defines a rule for threat level 8, which is a parameter that indicates the severity of the threat. Based on this configuration, the SRX Series device will do the following:

Packets from the infected hosts with a threat level of 8 or above will be dropped: The action block-and-drop under the rule means that the device will block any traffic from the infected hosts that have a threat level equal to or higher than 8. This will prevent the hosts from sending or receiving malicious commands or data.

No log message will be generated: The absence of any log option under the rule means that the device will not generate any log message for the blocked traffic. This may reduce the load on the device and the logging server, but it may also limit the visibility and analysis of the security events.

B) Chassis cluster member devices synchronize configuration using the control link: This statement iscorrectbecause the control link is used for configuration synchronization among other functions.

C) A control link failure causes the secondary cluster node to be disabled: This statement iscorrectbecause a control link failure causes the secondary node to become ineligible for primary role and remain in secondary role until the control link is restored.

E) Heartbeat messages verify that the chassis cluster control link is working: This statement iscorrectbecause heartbeat messages are sent periodically over the control link to monitor its status.
