NEW QUESTION # 40
Which two statements are correct about Juniper ATP Cloud? (Choose two.)
- A. The threat levels range from 0-100.
- B. The threat levels range from 0-10.
- C. Once the target threshold is met, Juniper ATP Cloud continues looking for threats levels range from 0 to 10 minutes.
- D. Once the target threshold is met, Juniper ATP Cloud continues looking for threats from 0 to 5 minutes.
Answer: A,B
Explanation:
In many threat intelligence and evaluation systems, including Juniper ATP Cloud, the threat levels are often scored on a scale to provide a quick reference of the potential risk associated with a threat. A common range for these threat levels is from 0 to 10, with 0 representing minimal or no threat and 10 representing a severe threat.
Alternatively, some systems may use a more granular scoring system ranging from 0 to 100, providing a more nuanced assessment of threat levels. This range allows for finer differentiation between the levels of threat severity.
NEW QUESTION # 41
A client has attempted communication with a known command-and-control server and it has reached the configured threat level threshold.
Which feed will the clients IP address be automatically added to in this situation?
- A. the custom cloud feed
- B. the allowlist and blocklist feed
- C. the infected host cloud feed
- D. the command-and-control cloud feed
Answer: C
Explanation:
Infected hosts are internal hosts that have been compromised by malware and are communicating with external C&C servers3. Juniper ATP Cloud provides infected host feeds that list internal IP addresses or subnets of infected hosts along with a threat level3. Once the Juniper ATP Cloud global threshold for an infected host is met, that host is added to the infected host feed and assigned a threat level of 10 by the cloud4. You can also configure your SRX Series device to block traffic from these IP addresses using security policies4.
NEW QUESTION # 42
Which two statements are true about the fab interface in a chassis cluster? (Choose two.)
- A. The fab link does not support fragmentation.
- B. The fab link supports traditional interface features.
- C. The physical interface for the fab link must be specified in the configuration.
- D. The Junos OS supports only one fab link.
Answer: A,C
Explanation:
The fabric link, used for data traffic synchronization between cluster nodes, is designed to handle packets at full size. It does not support packet fragmentation, which means that packets should be sized appropriately to avoid issues related to packet size limitations on the fab interface.
For chassis clustering, the specific physical interfaces used as fabric links (fab links) must be explicitly defined in the configuration. This specification is crucial to ensure proper data flow between nodes for state synchronization and other clustering functions.

You are asked to create a security policy that will automatically add infected hosts to the infected hosts feed and block further communication through the SRX Series device.
What needs to be added to this configuration to complete this task?
- A. Add a security intelligence policy to the permit portion of the security policy.
- B. Add logging to the permit portion of the security policy.
- C. Add a match rule to the security policy with an appropriate threat level.
- D. Add an action to the permit portion of the security policy.
Answer: A
Explanation:
To create a security policy that will automatically add infected hosts to the infected hosts feed and block further communication through the SRX Series device, you need to add a security intelligence policy to the permit portion of the security policy. A security intelligence policy is a policy that allows you to block or monitor traffic from malicious sources based on threat intelligence feeds from Juniper ATP Cloud or other providers. One of the feeds that you can use is the Infected-Hosts feed, which contains IP addresses of hosts that are infected with malware and communicate with command-and-control servers.
You can create a profile and a rule for the Infected-Hosts feed and specify the threat level and the action to take for the infected hosts. Then, you can link the security intelligence policy with the firewall policy and apply it to the traffic that you want to protect.

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.
NEW QUESTION # 49
When a security policy is modified, which statement is correct about the default behavior for active sessions allowed by that policy?
- A. Only policy changes that involve modification of the application will cause the active sessions affected by the change to be dropped.
- B. The active sessions allowed by the policy will continue unchanged.
- C. The active sessions allowed by the policy will be dropped.
- D. Only policy changes that involve modification of the action field will cause the active sessions affected by the change to be dropped.
Answer: B
Explanation:
When you modify a security policy on the SRX Series device, the default behavior is that the existing sessions that match the policy will continue unchanged. This means that the policy modification will only affect new sessions that are initiated after the change. However, you can change this behavior by using the clear-policy-session command, which will clear all the sessions that match the modified policy and force them to re-evaluate the new policy.

Which two statements about SRX Series device chassis clusters are correct? (Choose two.)
- A. The chassis cluster can contain a maximum of two devices.
- B. The chassis cluster data plane is connected with revenue ports.
- C. The chassis cluster data plane is connected with SPC ports.
- D. The chassis cluster can contain a maximum of three devices.
Answer: A,B
Explanation:
Two statements that are correct about SRX Series device chassis clusters are:
The chassis cluster data plane is connected with revenue ports: 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 cluster has two types of links: control links and fabric links. The control links are used for exchanging heartbeat messages and configuration synchronization between the nodes. The fabric links are used for forwarding data traffic between the nodes. The fabric links are connected with revenue ports, which are regular Ethernet interfaces that can also be used for normal traffic when not in cluster mode.
The chassis cluster can contain a maximum of two devices: A chassis cluster can only consist of two nodes: node 0 and node 1. The nodes must be the same model, have the same hardware configuration, run the same software version, and have the same license keys. The nodes share a common configuration and act as backup for each other in case of failure.

Which two statements are correct about a policy scheduler? (Choose two.)
- A. A policy scheduler can only be applied when using the policy-rematch feature.
- B. A policy scheduler determines the time frame that a security policy is actively evaluated.
- C. A policy scheduler can be defined using a daily schedule.
- D. A policy scheduler can be dynamically activated based on traffic flow volumes.
Answer: B,C
Explanation:
A policy scheduler is a feature that allows a security policy to be activated or deactivated for a specified time period. You can define schedulers for a single or recurrent time slot within which a policy is active.
Two statements that are correct about a policy scheduler are:
A policy scheduler can be defined using a daily schedule: You can configure a scheduler to be active every day for a certain time interval, such as from 8:00 AM to 5:00 PM. You can also exclude specific days from the daily schedule, such as weekends or holidays.
A policy scheduler determines the time frame that a security policy is actively evaluated: When you associate a scheduler with a security policy, the policy is only available for policy lookup during the time frame specified by the scheduler. When the scheduler is off, the policy is inactive and cannot be matched by any traffic.

NEW QUESTION # 54
Click the Exhibit button.
Referring to the exhibit, what will the SRX Series device do in this configuration?
- A. Packets from the infected hosts with a threat level of 8 will be dropped and no log message will be generated.
- B. Packets from the infected hosts with a threat level of 8 or above will be dropped and no log message will be generated.
- C. Packets from the infected hosts with a threat level of 8 will be dropped and a log message will be generated.
- D. Packets from the infected hosts with a threat level of 8 or above will be dropped and a log message will be generated.
Answer: B
Explanation:
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.
