NEW QUESTION # 37
Which solution enables you to create security policies that include user and group information?
- A. JIMS
- B. Network Director
- C. NETCONF
- D. ATP Appliance
Answer: A
Explanation:
The solution that enables you to create security policies that include user and group information is JIMS (Juniper Identity Management Service). JIMS collects and maintains a large database of user, device, and group information from Active Directory domains or syslog sources, and enables SRX Series devices to rapidly identify thousands of users in a large, distributed enterprise. With JIMS, you can create security policies that include user and group information, and enforce user-based access control policies to protect network resources.
NEW QUESTION # 38
You are configuring logging for a security policy.
In this scenario, in which two situations would log entries be generated? (Choose two.)
- A. every 10 minutes
- B. at session close
- C. every 60 seconds
- D. at session initialization
Answer: B,D
Explanation:
Log entries would be generated in two situations: at session initialization and at session close. At session initialization, the log entry would include details about the connection, such as the source and destination IP addresses, the service being used, and the action taken by the security policy.
At session close, the log entry would include details about the connection, such as the duration of the session, the bytes sent/received, and the action taken by the security policy.
NEW QUESTION # 39
Which method does the loT Security feature use to identify traffic sourced from IoT devices?

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 the domain Exchange server
- B. Connect JIMS to another SRX Series device.
- C. Connect JIMS to the domain SQL server.
- D. Connect JIMS to the RADIUS server
Answer: B
Explanation:
JIMS server is a Juniper Identity Management Service that collects user identity information from different authentication sources for SRX Series devices. It can connect to SRX Series devices and CSO platform in your network.
JIMS server is a service that protects corporate resources by authenticating and restricting user access based on roles. It connects to SRX Series devices and CSO platform to provide identity information for firewall policies. To reduce the load that JIMS server places on your network, you should connect JIMS to another SRX Series device. This way, you can distribute the identity information among multiple SRX Series devices and reduce network traffic.
NEW QUESTION # 44
Referring to the configuration shown in the exhibit, which two statements are true? (Choose two.)
- A. The log is being stored on the local Routing Engine.
- B. The syslog is configured for a user facility.
- C. The syslog is configured for an info facility.
- D. The log is being sent to a remote server.
Answer: B,D
NEW QUESTION # 45
You are asked to implement IPS on your SRX Series device.
In this scenario, which two tasks must be completed before a configuration will work? (Choose two.)
- A. Reboot the SRX Series device.
- B. Download the IPS signature database.
- C. Enroll the SRX Series device with Juniper ATP Cloud.
- D. Install the IPS signature database.
Answer: B,D
Explanation:
The two tasks that must be completed before a configuration for IPS on an SRX Series device will work are downloading the IPS signature database and installing the IPS signature database. The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to download and install the IPS signature database. Enrolling the SRX Series device with Juniper ATP Cloud is not necessary to make a configuration work, and rebooting the SRX Series device is not required either.
NEW QUESTION # 46
Which two statements are true about application identification? (Choose two.)
- A. Application signatures are the same as IDP signatures.
- B. Application signatures are not the same as IDP signatures.
- C. Application identification cannot identify nested applications that are within Layer 7.
- D. Application identification can identity nested applications that are within Layer 7.
Answer: B,D
Explanation:
Application identification is a feature that enables SRX Series devices to identify and classify network traffic based on application signatures or custom rules. Application identification can enhance security, visibility, and control over network applications. Two statements that are true about application identification are:
Application identification can identify nested applications that are within Layer 7: Nested applications are applications that run within another application protocol, such as HTTP or SSL. For example, Facebook or YouTube are nested applications within HTTP. Application identification can identify nested applications by inspecting the application payload and matching it against predefined or custom signatures.
Application signatures are not the same as IDP signatures: Application signatures are patterns of bytes or strings that uniquely identify an application protocol or a nested application. IDP signatures are patterns of bytes or strings that indicate an attack or an exploit against a vulnerability. Application signatures are used for application identification and classification, while IDP signatures are used for intrusion detection and prevention.
NEW QUESTION # 47
The DNS ALG performs which three functions? (Choose three.)
- A. The DNS ALG performs DNS load balancing.
- B. The DNS ALG modifies the DNS payload in NAT mode.
- C. The DNS ALG performs the IPv4 and IPV6 address transformations.
- D. The DNS ALG performs DNS doctoring.

Answer: B,C,D
NEW QUESTION # 48
You are asked to create an IPS-exempt rule base to eliminate false positives from happening.
Which two configuration parameters are available to exclude traffic from being examined?
(Choose two.)
- A. destination IP address
- B. destination port
- C. source IP address
- D. source port
Answer: C
Explanation:
To exclude traffic from being examined by IPS, you can use the source IP address and/or destination port as criteria for the exemption. This is achieved by configuring an IPS-exempt rule base that includes specific exemption rules based on these criteria.
NEW QUESTION # 49
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 physical interface for the fab link must be specified in the configuration.
- C. The Junos OS supports only one fab link.
- D. The fab link supports traditional interface features.
Answer: B,D
Explanation:
The physical interface for the fab link must be specified in the configuration. Additionally, the fab link supports traditional interface features such as MAC learning, security policy enforcement, and dynamic routing protocols. The fab link does not support fragmentation and the Junos OS supports up to two fab links.
NEW QUESTION # 50
Which statement defines the function of an Application Layer Gateway (ALG)?
- A. The ALG uses software processes for managing specific protocols.
- B. The ALG uses software that is used by a single TCP session using the same port numbers as the application.
- C. The ALG contains protocols that use one application session for each TCP session.
- D. The ALG uses software processes for permitting or disallowing specific IP address ranges.
Answer: A
Explanation:
The statement that defines the function of an Application Layer Gateway (ALG) is: The ALG uses software processes for managing specific protocols. An ALG is a security component that operates at the application layer (layer 7) of the OSI model and handles data associated with certain application protocols, such as SIP, FTP, RTSP, etc. An ALG acts as a proxy or intermediary between the client and the server applications and performs various functions, such as address and port translation, resource allocation, application response control, and synchronization of data and control traffic. An ALG can also inspect and modify the application payload to enable firewall or NAT traversal, prevent spoofing or DoS attacks, or enforce granular security policies based on application-specific commands.
