Which two solutions will fulfill the minimum requirements for this deployment? (Choose two.)
- A. a single vSRX
- B. a cSRX for firewall services and a separate cSRX for NAT services
- C. a vSRX for firewall services and a separate vSRX for NAT services
- D. a single cSRX
Answer: A,D
Explanation:
A single vSRX instance is capable of handling both firewall and NAT services simultaneously. This solution provides a streamlined and resource-efficient way to secure and manage network traffic within a private cloud environment.
Similar to the vSRX, a single cSRX can also provide both firewall and NAT services. The cSRX, being a containerized version of the SRX, is particularly suited for environments where high density and microservices architectures are used, offering high performance in a compact form factor.
NEW QUESTION # 49
Exhibit
Which two statements are correct about the configuration shown in the exhibit? (Choose two.)
- A. The session-class parameter in only used when troubleshooting.
- B. Every session that enters the SRX Series device will generate an event
- C. Replacing the session-init parameter with session-lose will log unidentified flows.
- D. The others 300 parameter means unidentified traffic flows will be dropped in 300 milliseconds.
Answer: B,C
Explanation:
The log session-init; command within the policy configuration specifies that an event log entry will be created every time a session is initialized, meaning each new session will generate a log event. This is useful for tracking and analyzing the traffic flows entering the device.
Changing session-init to session-close in the log statement would mean that the device logs sessions when they close instead of when they open. This setting is typically used to log details about the session upon termination, which can help in analyzing the duration, end status, and other parameters of sessions, including those of unidentified flows.

NEW QUESTION # 51
You want to manually failover the primary Routing Engine in an SRX Series high availability cluster pair.
Which step is necessary to accomplish this task?
- A. Implement the control link recover/ solution before adjusting the priorities.
- B. Issue the set chassis cluster disable reboot command on the primary node.
- C. Adjust the priority in the configuration on the secondary node.
- D. Manually request the failover and identify the secondary node
Answer: D
Explanation:
This step involves issuing a command to manually initiate a failover from the primary Routing Engine to the secondary. This can typically be done using a command like request chassis cluster failover redundancy-group <group-number> node <node-id>, where <group-number> is the redundancy group you are failing over, and <node-id> specifies the node to which you want to failover (usually the secondary node). This command forces the designated node to take over as primary for the specified redundancy group.
NEW QUESTION # 52
Which two statements are correct about security policy changes when using the policy rematch feature? (Choose two.)
- A. When a policy change includes changing the policy's action from permit to deny, all existing sessions are dropped.
- B. When a policy change includes changing the policy's source or destination address match condition, all existing sessions are dropped.
- C. When a policy change includes changing the policy's action from permit to deny, all existing sessions are maintained
- D. When a policy change includes changing the policy's source or destination address match condition, all existing sessions are reevaluated.
Answer: A,D
Explanation:
policy rematch is a feature that enables the device to reevaluate an active session when its associated security policy is modified. The session remains open if it still matches the policy that allowed the session initially. The session is closed if its associated policy is renamed, deactivated, or deleted1.

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 # 60
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,D
Explanation:
When JSA (Juniper Secure Analytics) receives external events and flows, the typical processing steps are:
Option C. Before the information is filtered, the information is formatted.
Data formatting is an initial step in the process where raw data from events and flows is converted into a standard format that can be more easily processed and analyzed by JSA.
Option A. After formatting the data, the data is stored in an asset database.
Once the data is formatted, it is stored in an asset database. This database acts as a repository for all the formatted data, enabling JSA to perform further analysis, correlation, and eventually, to maintain a comprehensive view of the network assets and activities.
These steps are part of JSA's comprehensive approach to security event management, which involves collecting, normalizing, and analyzing data to identify potential security threats and vulnerabilities efficiently.
NEW QUESTION # 61
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. Each chassis cluster member device can host active redundancy groups
- D. Redundancy group 0 is only active on the cluster backup node.
Answer: A,C
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 # 62
Which two features are configurable on Juniper Secure Analytics (JSA) to ensure that alerts are triggered when matching certain criteria? (Choose two.)
- A. assets
- B. tests
- C. events
- D. building blocks
Answer: B,D
Explanation:
Building blocks in JSA are reusable components that define specific attributes or behaviors in the network traffic. They can be used to create complex criteria for alerts. By combining multiple building blocks, you can specify detailed conditions under which alerts should be triggered, such as combinations of events or specific sequences of actions within the network.
Tests in JSA are conditions or rules that analyze log or flow data to detect unusual or malicious activity.
You can configure tests to evaluate the data against predefined criteria, which, when met, will trigger alerts. These tests are essential for identifying potential security incidents and ensuring that relevant alerts are issued in a timely manner.
NEW QUESTION # 63
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 client devices.
- D. Enable time synchronization on the JIMS server.
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.
