NEW QUESTION # 21
What are two benefits of using a vSRX in a software-defined network? (Choose two.)
- A. scalability
- B. granular security
- C. no required software license
- D. infinite number of interfaces
Answer: A,B
Explanation:
- Scalability: vSRX instances can be easily added or removed as the needs of the network change, making it a flexible option for scaling in a software-defined network.
- Granular Security: vSRX allows for granular security policies to be enforced at the virtual interface level, making it an effective solution for securing traffic in a software-defined network.
The two benefits of using a vSRX in a software-defined network are scalability and granular security.
Scalability allows you to increase the number of resources available to meet the demands of network traffic, while granular security provides a level of control and flexibility to your network security that is not possible with a traditional firewall. With a vSRX, you can create multiple levels of security policies, rules, and access control lists to ensure that only authorized traffic can enter and exit your network.
Additionally, you would not require a software license to use the vSRX, making it an economical solution for those looking for increased security and flexibility.
NEW QUESTION # 22
When a security policy is deleted, which statement is correct about the default behavior of active sessions allowed by that policy?
- A. The active sessions allowed by the policy will continue
- B. The active sessions allowed by the policy will be marked as a legacy flow and will continue to be forwarded.
- C. The active sessions allowed by the policy will be dropped.
- D. The active sessions allowed by the policy will be reevaluated by the cached
Answer: B
Explanation:
When a security policy is deleted, the existing sessions that were previously allowed by that policy are not immediately dropped; instead, they are typically treated as legacy flows. This means they are allowed to continue until they naturally end or until the session timeout is reached. This behavior ensures that deleting a policy does not abruptly disrupt ongoing traffic flows that were previously authorized by that policy. This approach helps in avoiding unintended service disruptions, especially in production environments where active connections may be critical to operations.
NEW QUESTION # 23
Which two statements about SRX Series device chassis clusters are true? (Choose two.)
- A. Chassis cluster member devices must be the same model.
- B. Each chassis cluster member requires a unique cluster ID value.
- C. Redundancy group 0 is only active on the cluster backup node.
- D. Each chassis cluster member device can host active redundancy groups
Answer: A,D
Explanation:
In a chassis cluster, both nodes can host active redundancy groups. The active redundancy groups can be distributed between the two nodes, depending on the configuration and failover status, allowing each node to handle traffic for different sets of services or interfaces.
For the chassis clustering to function correctly, both nodes in the cluster must be of the same model.
This requirement ensures that the hardware capabilities, such as processing power and interface compatibility, are identical, which is crucial for maintaining consistent performance and behavior between cluster nodes.
NEW QUESTION # 24

Click the Exhibit button.
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 logging to the permit portion of the security policy.
- B. Add a match rule to the security policy with an appropriate threat level.
- C. Add an action to the permit portion of the security policy.
- D. Add a security intelligence policy to the permit portion of the security policy.
Answer: D
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.

NEW QUESTION # 31
What information does encrypted traffic insights (ETI) use to notify SRX Series devices about known malware sites?
- A. domain names
- B. dynamic address groups
- C. MAC addresses
- D. certificates
Answer: A
Explanation:
Encrypted traffic insights (ETI) uses domain names to notify SRX Series devices about known malware sites. ETI is a feature of the SRX Series firewall that can detect and block malware that is hidden in encrypted traffic. It works by analyzing the domain names of the websites that the encrypted traffic is attempting to access. If the domain name matches a known malware site, ETIwill send an alert to the SRX Series device, which can then take appropriate action to block the traffic. ETI is a useful tool for protecting against threats that attempt to evade detection by hiding in encrypted traffic.

- B. APPID
- C. URL filtering
- D. content filtering
Answer: A,B
Explanation:
Micro application detection is a feature that enables more granular control over applications by identifying and taking action on sub-features or specific behaviors within an application. For example, allowing access to Facebook while blocking Facebook Chat.
Application Identification (APPID) is a feature that identifies and controls applications based on their traffic patterns and characteristics. APPID can be configured to recognize not only the main application but also its various subcomponents, allowing for precise control over what is allowed or blocked.
NEW QUESTION # 33
You are troubleshooting unexpected issues on your JIMS server due to out of order event log timestamps.
Which action should you take to solve this issue?
- A. Enable time synchronization on the JIMS server.
- B. Enable time synchronization on the domain controllers.
- C. Enable time synchronization on the SRX Series devices.
- D. Enable time synchronization on the client devices.
Answer: B
Explanation:
To solve the issue of out of order event log timestamps on your JIMS server, you should enable time synchronization on the domain controllers. 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 and CSO for identity-based security policies. JIMS relies on the timestamps of the event logs generated by the domain controllers to track user logins, logouts, and IP address changes. If the domain controllers have different or inaccurate clocks, the event logs may have out of order or incorrect timestamps, which can cause JIMS to miss or misinterpret some events and affect its accuracy and performance. Therefore, you should ensure that all the domain controllers in your network are synchronized with a reliable time source, such as an NTP server or a Windows Time service.

How does the SSL proxy detect if encryption is being used?
- A. It queries the client device.
- B. It uses application identity services.
- C. It looks at the destination port number.
- D. It verifies the length of the packet
Answer: C
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.
NEW QUESTION # 37
Which solution enables you to create security policies that include user and group information?
- A. ATP Appliance
- B. NETCONF
- C. Network Director
- D. JIMS
Answer: D
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.
