Click the Exhibit button.
Which two statements describe the output shown in the exhibit? (Choose two.)
- A. Node 1 is controlling traffic for redundancy group 1.
- B. Redundancy group 1 experienced an operational failure.
- C. Redundancy group 1 was administratively failed over.
- D. Node 0 is controlling traffic for redundancy group 1.
Answer: A,C
Explanation:
The output shown in the exhibit displays the status of a chassis cluster redundancy group (RG) on an SRX Series device. A chassis cluster RG is a collection of objects, such as interfaces or services, that fail over together from one node to another in case of a failure or manual intervention. A chassis cluster RG can be primary on one node and backup on another node at any given time. Two statements that describe the output shown in the exhibit are:
Redundancy group 1 was administratively failed over: The output shows that redundancy group 1 has "Manual failover" set to "Yes". This indicates that redundancy group 1 was manually switched from one node to another using the request chassis cluster failover redundancy-group command.
Node 1 is controlling traffic for redundancy group 1: The output shows that node 1 has "Status" set to "Primary" for redundancy group 1. This means that node 1 is active and controlling traffic for redundancy group 1.
NEW QUESTION # 37
You want to permit access to an application but block application sub-Which two security policy features provide this capability? (Choose two.)
- A. URL filtering
- B. micro application detection
- C. APPID
- D. content filtering
Answer: A,B
Explanation:
The two security policy features that provide the capability to permit access to an application but block its sub-applications are URL filtering and micro application detection. URL filtering allows you to create policies that permit or block access to certain websites or webpages based on URL patterns. Micro application detection is a more sophisticated approach that can identify and block specific applications, even if they are embedded within other applications or websites. According to the Juniper Networks Certified Internet Specialist (JNCIS-SEC) Study Guide [1], "micro application detection is the most accurate way to detect and control applications." Content filtering and APPID are more general approaches and are not as effective in providing the level of granularity needed to block sub-applications.
NEW QUESTION # 38
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 command-and-control cloud feed
- C. the infected host cloud feed
- D. the allowlist and blocklist feed
Answer: C
Explanation:
Infected hosts are internal hosts that have been compromised by malware and are communicating with external C&C servers. Juniper ATP Cloud provides infected host feeds that list internal IP addresses or subnets of infected hosts along with a threat level. 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 cloud. You can also configure your SRX Series device to block traffic from these IP addresses using security policies.
NEW QUESTION # 39
You want to set up JSA to collect network traffic flows from network devices on your network.
Which two statements are correct when performing this task? (Choose two.)
- A. Superflows reduce traffic licensing requirements.
- B. Statistical sampling decreases event correlation accuracy.
- C. Statistical sampling increases processor utilization
- D. BGP FlowSpec is used to collect traffic flows from Junos OS devices.
Answer: B,D
Explanation:
The two correct statements when performing this task are A.
BGP FlowSpec is used to collect traffic flows from Junos OS devices, and C.
Statistical sampling decreases event correlation accuracy.
BGP FlowSpec is a Junos OS feature that allows network devices to send traffic flow information to a Juniper security device using BGP.
This allows the Juniper security device to monitor and collect the traffic flows and analyze them for suspicious activity.
Statistical sampling increases processor utilization by selecting only a subset of the data to be analyzed, which can help reduce the amount of data sent to the security device.
However, this also decreases the accuracy of event correlation, as some events may be missed due to the sampling. Superflows reduce traffic licensing requirements by offloading the processing of certain traffic flows to the device itself, instead of having it sent to the security device.
NEW QUESTION # 40

NEW QUESTION # 42
Which two statements are correct when considering IPS rule base evaluation? (Choose two.)
- A. IPS evaluates rules sequentially
- B. IPS applies the least severe action to traffic matching multiple rules.
- C. IPS applies the most severe action to traffic matching multiple rules,
- D. IPS evaluates rules concurrently.
Answer: C,D
Explanation:
Reference:
The Intrusion Prevention System (IPS) is a feature that provides protection against network-based threats. The IPS uses a rule base to evaluate network traffic and apply actions based on the rules that match the traffic.
When evaluating the rule base, the IPS evaluates the rules concurrently (option A). This means that the IPS can apply multiple rules to the same traffic simultaneously.
If multiple rules match the same traffic, the IPS applies the most severe action (option B). This means that if there are conflicting actions specified in different rules, the IPS will apply the action that has the highest severity. For example, if one rule specifies a "drop" action and another rule specifies a "log" action for the same traffic, the IPS will drop the traffic because dropping has a higher severity than logging.
NEW QUESTION # 43

- A. The current sessions are torn down and go through first path processing based on the new route.
- B. The current session are torn dowm only if the policy-rematch option has been enabled.
- C. The current sessions might change based on the corresponding security policy.
- D. The current sessions do not change.
Answer: D
NEW QUESTION # 46
After JSA receives external events and flows, which two steps occur? (Choose two.)
- A. Before the information is filtered, the information is formatted
- B. Before formatting the data, the data is analyzed for relevant information.
- C. After the information is filtered, JSA responds with active measures
- D. After formatting the data, the data is stored in an asset database.
Answer: A,B
Explanation:
Before formatting the data, the data is analyzed for relevant information. This is done to filter out any irrelevant data and to extract any useful information from the data. After the information is filtered, it is then formatted so that it can be stored in an asset database. After the data has been formatted, JSA will then respond with active measures.
NEW QUESTION # 47

- A. prior to security policy processing
- B. prior to the route lookup
- C. after source NAT services are applied
- D. after ALG services are applied
Answer: B
NEW QUESTION # 48
Which two statements are correct about the configuration shown in the exhibit? (Choose two.)
- A. Replacing the session-init parameter with session-lose will log unidentified flows.
- B. The others 300 parameter means unidentified traffic flows will be dropped in 300 milliseconds.
- C. The session-class parameter in only used when troubleshooting.
- D. Every session that enters the SRX Series device will generate an event
Answer: B,D
Explanation:
The configuration shown in the exhibit is for a Juniper SRX Series firewall. The session-init parameter is used to control how the firewall processes unknown traffic flows. With the session- init parameter set to 300, any traffic flows that the firewall does not recognize will be dropped after 300 milliseconds. Additionally, every session that enters the device, whether it is known or unknown, will generate an event, which can be used for logging and troubleshooting purposes.
The session-lose parameter is used to control how the firewall handles established sessions that are terminated.

- A. APBR
- B. AppFW
- C. AppQoS
- D. AppQoE
Answer: A
Explanation:
APBR (Application Path-Based Routing) is an AppSecure component which can be used to route traffic from the degraded link to the working link in order to reduce packet loss. APBR is a policy-based routing solution that allows you to configure rules to direct traffic to the most appropriate path, based on application, user, or network metrics.
NEW QUESTION # 53
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 SRX Series devices.
- B. Enable time synchronization on the domain controllers.
- C. Enable time synchronization on the JIMS server.
- 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.

What are two benefits of using a vSRX in a software-defined network? (Choose two.)
- A. no required software license
- B. infinite number of interfaces
- C. granular security
- D. scalability
Answer: C,D
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.

Which two features are configurable on Juniper Secure Analytics (JSA) to ensure that alerts are triggered when matching certain criteria? (Choose two.)
- A. building blocks
- B. events
- C. tests
- D. assets
Answer: B,C
Explanation:
The two configurable features on Juniper Secure Analytics (JSA) that can be used to ensure that alerts are triggered when matching certain criteria are events and tests. Events refer to the collection of data from different sources, while tests are used to define the criteria for which an alert is triggered. For example, you can use events to collect data from a firewall and tests to define criteria such as IP address, port number, and the type of traffic.
