For more information on loT Security, please refer to the Juniper Security, Specialist (JNCIS-SEC) study guide.
NEW QUESTION # 57
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. Download the IPS signature database.
- B. Reboot the SRX Series device.
- C. Enroll the SRX Series device with Juniper ATP Cloud.
- D. Install the IPS signature database.
Answer: A,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 # 58
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 be marked as a legacy flow and will continue to be forwarded.
- B. The active sessions allowed by the policy will be reevaluated by the cached
- C. The active sessions allowed by the policy will continue
- D. The active sessions allowed by the policy will be dropped.
Answer: D
Explanation:
When a security policy is deleted, the active sessions allowed by the policy will be dropped. The default behavior is that all active sessions allowed by the policy will be terminated and the traffic will no longer be forwarded. There is no way to mark the active sessions as a legacy flow or to reevaluate them by the cached rules.
Reference:
According to Juniper Networks Security, Specialist (JNCIS-SEC) Study Guide, when a security policy is deleted, the active sessions allowed by that policy will be dropped. This behavior is the default behavior of the device. There is no way to mark the active sessions as a legacy flow or to re-evaluate them against cached rules. The device will terminate the active sessions and will no longer forward traffic for those sessions.
NEW QUESTION # 59
Your manager asks you to provide firewall and NAT services in a private cloud. Which two solutions will fulfill the minimum requirements for this deployment? (Choose two.)
- A. a cSRX for firewall services and a separate cSRX for NAT services
- B. a single vSRX
- C. a vSRX for firewall services and a separate vSRX for NAT services
- D. a single cSRX
Answer: A,C
Explanation:
A single vSRX or cSRX cannot provide both firewall and NAT services simultaneously. To meet the minimum requirements for this deployment, you need to deploy a vSRX for firewall services and a separate vSRX for NAT services (option B), or a cSRX for firewall services and a separate cSRX for NAT services (option C).
NEW QUESTION # 60
Which two statements are correct about Juniper ATP Cloud? (Choose two.)

- B. Once the target threshold is met, Juniper ATP Cloud continues looking for threats from 0 to 5 minutes.
- C. The threat levels range from 0-10.
- D. The threat levels range from 0-100.
Answer: B,C
Explanation:
According to the Juniper Networks JNCIS-SEC Study Guide, Juniper ATP Cloud sets target thresholds for security events and then continuously scans the environment for any activity that exceeds this threshold. Once the threshold is met, Juniper ATP Cloud continues looking for threats for a period of 0 to 5 minutes. The threat levels range from 0 to 10, with 0 being the lowest and 10 being the highest.
NEW QUESTION # 61
You are asked to determine how much traffic a popular gaming application is generating on your network.
Which action will you perform to accomplish this task?
- A. Enable AppQoS on the proper security zones
- B. Enable screen options on the proper security zones
- C. Enable AppTrack on the proper security zones.
- D. Enable APBR on the proper security zones
Answer: C
Explanation:
AppTrack is a feature of Juniper Networks firewall solutions that allows administrators to track applications, users, and the amount of traffic generated by those applications on the network.
AppTrack can be enabled on specific security zones of the network to monitor traffic on those zones. This feature can be used to determine how much traffic a popular gaming application is generating on the network.
AppTrack is a feature of the Junos OS that provides visibility into the applications and users on your network. It tracks the usage of applications and provides detailed reports on the amount of traffic generated by each application. By enabling AppTrack on the proper security zones, you can determine how much traffic a popular gaming application is generating on your network.

NEW QUESTION # 63
Which three statements about SRX Series device chassis clusters are true? (Choose three.)
- A. Recovery from a control link failure requires that the secondary member device be rebooted.
- B. A control link failure causes the secondary cluster node to be disabled.
- C. Chassis cluster member devices synchronize configuration using the control link.
- D. Chassis cluster control links must be configured using RFC 1918 IP addresses.
- E. Heartbeat messages verify that the chassis cluster control link is working.
Answer: B,C,E
Explanation:
1. Chassis cluster member devices synchronize configuration using the control link: This statement is correct because the control link is used for configuration synchronization among other functions.
2. A control link failure causes the secondary cluster node to be disabled: This statement is correct because a control link failure causes the secondary node to become ineligible for primary role and remain in secondary role until the control link is restored.
3. Heartbeat messages verify that the chassis cluster control link is working: This statement is correct because heartbeat messages are sent periodically over the control link to monitor its status.

- A. AppQoS
- B. AppFW
- C. AppQoE
- D. APBR
Answer: D
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 # 69

NEW QUESTION # 70
Which solution enables you to create security policies that include user and group information?
- A. NETCONF
- B. JIMS
- C. Network Director
- D. ATP Appliance
Answer: B
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 # 73
Which two statements are correct about chassis clustering? (Choose two.)
- A. The cluster ID is used to identify each device in the chassis cluster.
- B. The node ID is used to identify each device in the chassis cluster.
- C. A system reboot is required to activate changes to the cluster.
- D. The node ID value ranges from 1 to 255.
Answer: B,D
Explanation:
The node ID value ranges from 1 to 255 and is used to identify each device in the chassis cluster.
The cluster ID is also used to identify each device, but it is not part of the node ID configuration. A system reboot is not required to activate changes to the cluster, but it is recommended to ensure that all changes are applied properly.
