NEW QUESTION # 97
You just finished setting up your command-and-control (C&C) category with Juniper ATP Cloud.
You notice that all of the feeds have zero objects in them.
Which statement is correct in this scenario?
- A. The security intelligence policy must be configured; on a unified security policy
- B. No action is required, the feeds take a few minutes to download.
- C. Set the maximum C&C entries within the Juniper ATP Cloud GUI.
- D. Use the commit full command to start the download.
Answer: B
Explanation:
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.

NEW QUESTION # 101
Exhibit
You are asked to track BitTorrent traffic on your network. You need to automatically add the workstations to the High_Risk_Workstations feed and the servers to the BitTorrent_Servers feed automatically to help mitigate future threats.
Which two commands would add this functionality to the FindThreat policy? (Choose two.)
- A.
- B.
- C.
- D.
Answer: B,C
Explanation:
Explanation
To track BitTorrent traffic on your network, you need to use the Security Intelligence feature, which allows you to apply actions to traffic based on predefined or custom feeds. The High_Risk_Workstations and BitTorrent_Servers are examples of custom feeds that you can create and populate with IP addresses of devices that match certain criteria. To automatically add the workstations and servers to the respective feeds, you need to use the administration-feed option under the application-services security-intelligence hierarchy.
This option specifies the feed name and the action to be taken for the traffic that matches the feed. For example, to add the workstations to the High_Risk_Workstations feed and drop the traffic, you would use:
set security policies from-zone untrust policy FindThreat then permit application-services security-intelligence administration-feed High_Risk_Workstations drop To add the servers to the BitTorrent_Servers feed and log the traffic, you would use:
set security policies from-zone untrust policy FindThreat then permit application-services security-intelligence administration-feed BitTorrent_Servers log Option B and Option C show the correct commands for these scenarios. Option A and Option D are incorrect because they use the wrong syntax for the administration-feed option. They also use the wrong feed names, as the feeds are case-sensitive and must match the ones defined under the security-intelligence hierarchy.

NEW QUESTION # 102
Which two statements are correct about AppTrack? (Choose two.)
- A. AppTrack can be configured for any defined logical system on an SRX Series device.
- B. AppTrack can only be configured in the main logical system on an SRX Series device.
- C. AppTrack collects traffic flow information including byte, packet, and duration statistics.
- D. AppTrack identifies and blocks traffic flows that might be malicious regardless of the ports being used.
Answer: A,C
Explanation:
AppTrack is a feature that allows you to monitor and analyze the application traffic on your SRX Series device. It can be configured for any defined logical system, which is a virtual router or switch within a physical device. AppTrack collects statistics such as bytes, packets, and duration for each application flow and displays them in reports or logs. AppTrack does not identify or block malicious traffic, that is the function of AppSecure or IDP/IPS.

NEW QUESTION # 104
Which two statements are correct about JSA data collection? (Choose two.)
- A. The Flow Collector parses logs.
- B. The Flow Collector can use statistical sampling
- C. The Event Collector parses logs
- D. The Event Collector collects information using BGP FlowSpec.
Answer: B,C
Explanation:
Explanation
Juniper Secure Analytics (JSA) is a security information and event management (SIEM) system that consolidates, analyzes, and manages surveillance data from network devices, endpoints, and applications. JSA uses two types of data collectors: Event Collector and Flow Collector1 The Event Collector collects and parses logs from various log sources, such as firewalls, routers, servers, and intrusion detection or prevention systems. The Event Collector normalizes the log data into a common format and sends it to the JSA console for further analysis and correlation. The Event Collector supports different protocols for log collection, such as syslog, SNMP, JDBC, and SDEE12 The Flow Collector collects and processes network traffic data from various flow sources, such as Flowlog files, NetFlow, J-Flow, sFlow, and Packeteer. The Flow Collector enriches the flow data with additional information, such as application identification, geolocation, and threat intelligence. The Flow Collector sends the flow data to the JSA console for further analysis and correlation. The Flow Collector can use statistical sampling to reduce the amount of flow data that is collected and processed, which can improve the performance and scalability of the system12 The Event Collector does not collect information using BGP FlowSpec, which is a protocol that allows the distribution of traffic flow specification rules among BGP peers. BGP FlowSpec is not a supported flow source for JSA3 The Flow Collector does not parse logs, which are textual records of network activity generated by log sources. The Flow Collector only handles flow data, which are binary records of network traffic generated by flow sources12 References: 1: Data Collection | JSA 7.5.0 | Juniper Networks 2: Data Collection - TechLibrary - Juniper Networks 3: Understanding BGP FlowSpec - TechLibrary - Juniper Networks

NEW QUESTION # 107
While working on an SRX firewall, you execute the show security policies policy-name <name> detail command.
Which function does this command accomplish?
- A. It identifies the different custom policies enabled.
- B. It shows policy counters for a configured policy.
- C. It shows the system log files for the local SRX Series device.
- D. It displays details about the default security policy.
Answer: B
Explanation:
The function that the show security policies policy-name <name> detail command accomplishes is showing policy counters for a configured policy. Policy counters are statistics that indicate how many times a policy has been matched by traffic and what actions have been taken by the policy. Policy counters can help you monitor and troubleshoot the performance and effectiveness of your security policies. The show security policies policy-name <name> detail command displays detailed information about a specific policy, such as its source zone, destination zone, description, state, hit count, byte count, packet count, action count, and session count.
NEW QUESTION # 108
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 a log message will be generated.
- B. Packets from the infected hosts with a threat level of 8 will be dropped and no log message will be generated.
- C. Packets from the infected hosts with a threat level of 8 or above 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 no log message will be generated.
Answer: D
NEW QUESTION # 109
You are asked to reduce the load that the JIMS server places on your Which action should you take in this situation?
- A. Connect JIMS to another SRX Series device.
- B. Connect JIMS to the domain SQL server.
- C. Connect JIMS to the domain Exchange server
- D. Connect JIMS to the RADIUS server
Answer: C
Explanation:
Explanation
JIMS uses eventlogs on Domain contollers or Exchange Servers to determine logon events. So to decrease the load on a Domain Controller you could use the Exchange Server to read logs.
