You are asked to ensure that if the session table on your SRX Series device gets close to exhausting its resources, that you enforce a more aggress.ve age-out of existing flows. In this scenario, which two statements are correct? (Choose two.)
- A. The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high-watermark value is met.
- B. The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the low-watermark value is met.
- C. The high-watermark configuration specifies the percentage of how much of the session table is left before disabling a more aggressive age- out timer.
- D. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer
Answer: A,D
Explanation:
The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high-watermark value is met. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer.
This ensures that the session table does not become full and cause traffic issues, and also ensures that existing flows are aged out quickly when the table begins to get close to being full.

Which two statements are correct about JSA data collection? (Choose two.)
- A. The Flow Collector can use statistical sampling
- B. The Event Collector parses logs
- C. The Event Collector collects information using BGP FlowSpec.
- D. The Flow Collector parses logs.
Answer: A,B
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 # 41
Which two functions does Juniper ATP Cloud perform to reduce delays in the inspection of files? (Choose two.)
- A. Juniper ATP Cloud uses a single antivirus software package to analyze files.
- B. Juniper ATP Cloud allows end users to bypass the inspection of files.
- C. Juniper ATP Cloud allows the creation of allowlists.
- D. Juniper ATP Cloud performs a cache lookup on files.
Answer: C,D
Explanation:
Juniper ATP Cloud is a cloud-based service that provides advanced threat prevention and detection for your network. It integrates with SRX Series firewalls and MX Series routers to analyze files and network traffic for signs of malicious activity. Two functions that Juniper ATP Cloud performs to reduce delays in the inspection of files are:
Juniper ATP Cloud allows the creation of allowlists: Allowlists are lists of trusted files or file hashes that are excluded from scanning by Juniper ATP Cloud. You can create allowlists based on file name, file type, file size, file hash, or sender domain. By using allowlists, you can reduce the number of files that need to be uploaded to Juniper ATP Cloud for analysis and improve the performance and efficiency of your network.
Juniper ATP Cloud performs a cache lookup on files: Cache lookup is a process that checks if a file has been previously scanned by Juniper ATP Cloud and if there is a cached verdict for it. If there is a cached verdict, Juniper ATP Cloud returns it immediately without scanning the file again. If there is no cached verdict, Juniper ATP Cloud uploads the file for analysis. By using cache lookup, you can reduce the time and bandwidth required for scanning files by Juniper ATP Cloud.

NEW QUESTION # 44
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 infected host cloud feed
- C. the command-and-control cloud feed
- D. the allowlist and blocklist feed
Answer: B
Explanation:
Explanation
The infected host cloud feed is a list of IP addresses that have been identified as compromised or infected by malware. The feed is updated by Juniper ATP Cloud based on the detection of malicious activity from the hosts, such as contacting known command-and-control servers. When a host on the network reaches the configured threat level threshold, its IP address is automatically added to the infected host cloud feed and blocked from communicating with any other hosts on the Internet. The other feeds are not relevant for this situation. The command-and-control cloud feed is a list of IP addresses that are known to be used by malware for remote control and communication. The allowlist and blocklist feed is a user-defined list of IP addresses that are either allowed or denied by the SRX Series device. The custom cloud feed is a user-defined list of IP addresses that are associated with a specific category or threat level. References:

NEW QUESTION # 49
Which two statements are correct about the Junos IPS feature? (Choose two.)
- A. IPS uses protocol anomaly rules to detect unknown attacks.
- B. IPS is integrated as a security service on SRX Series devices.
- C. IPS is a standalone platform running on dedicated hardware or as a virtual device.
- D. IPS uses sandboxinQ to detect unknown attacks.
Answer: A,B
Explanation:
Explanation
The Junos IPS feature is a security service that is integrated on SRX Series devices, which are high-performance network security platforms that offer firewall, VPN, IPS, application security, and unified threat management capabilities. The Junos IPS feature uses various methods to detect and prevent intrusions, such as signature-based detection, protocol anomaly detection, behavioral anomaly detection, and custom signatures. Signature-based detection compares network traffic against predefined patterns of known attacks and blocks traffic when a match is found. Protocol anomaly detection monitors network traffic for deviations from the expected or normal behavior of common protocols, such as HTTP, FTP, SMTP, and DNS, and blocks traffic when an anomaly is detected. Behavioral anomaly detection monitors network traffic forchanges in the baseline behavior of hosts, networks, or applications, and blocks traffic when a significant deviation is detected. Custom signatures allow administrators to create their own patterns of attacks based on specific criteria, such as IP addresses, ports, protocols, or payload content, and block traffic when a match is found.
The Junos IPS feature does not use sandboxing to detect unknown attacks, as this is a function of the Juniper ATP Cloud service, which is a cloud-based service that provides advanced malware detection and prevention for the network. The Junos IPS feature is not a standalone platform, but rather a service that runs on SRX Series devices, which can be deployed as physical or virtual appliances. References:

NEW QUESTION # 50
You are trying to create a security policy on your SRX Series device that permits HTTP traffic from your private 172 25.11.0/24 subnet to the Internet. You create a policy named permit-http between the trust and untrust zones that permits HTTP traffic. When you issue a commit command to apply the configuration changes, the commit fails with the error shown in the exhibit.
Which two actions would correct the error? (Choose two.)
- A. Modify the security policy to use the built-in Junos-http applications.
- B. Create a custom application named http at the [edit applications] hierarchy.
- C. Issue the rollback 1 command from the top of the configuration hierarchy and attempt the commit again.
- D. Execute the Junos commit full command to override the error and apply the configuration.
Answer: A,B
Explanation:
The error message indicates that the Junos-http application is not defined, so you need to either create a custom application or modify the security policy to use the built-in Junos-http application.
Doing either of these will allow you to successfully commit the configuration.
NEW QUESTION # 51
How does the SSL proxy detect if encryption is being used?
- A. It verifies the length of the packet
- B. It looks at the destination port number.
- C. It queries the client device.
- D. It uses application identity services.
Answer: B
Explanation:
The SSL proxy can detect if encryption is being used by looking at the destination port number of the packet. If the port number is 443, then the proxy can assume that the packet is being sent over an encrypted connection. If the port number is different, then the proxy can assume that the packet is not encrypted. For more information, please refer to the Juniper Networks JNCIS-SEC Study Guide.
Reference:
The SSL proxy is a security feature that provides visibility and control over SSL/TLS encrypted traffic. When SSL proxy is enabled, it intercepts SSL/TLS traffic and decrypts it to allow visibility into the content of the encrypted traffic. However, before decrypting the traffic, the SSL proxy must first determine if the traffic is encrypted.
To detect if encryption is being used, the SSL proxy looks at the destination port number. If the destination port number is a known SSL/TLS port (e.g., TCP port 443), the SSL proxy assumes that encryption is being used and intercepts the traffic. If the destination port is not a known SSL/TLS port, the SSL proxy does not intercept the traffic and allows it to pass through the device unmodified.
