Referring to the exhibit, which IKE mode will be configured on the HQ-Gateway and Subsidiary- Gateway?

Main mode on both the gateways
Aggressive mode on both the gateways

Answer(s): B

QUESTION: 22

You are deploying threat remediation to endpoints connected through third-party devices. In this scenario, which three statements are correct? (Choose three.)

All third-party switches must support AAA/RADIUS and Dynamic Authorization Extensions to the RADIUS protocol.
The connector uses an API to gather endpoint MAC address information from the RADIUS server.
All third-party switches in the specified network are automatically mapped and registered with the RADIUS server.
The connector queries the RADIUS server for the infected host endpoint details and initiates a change of authorization (CoA) for the infected host.
The RADIUS server sends Status-Server messages to update infected host information to the connector.

Answer(s): A,B,D

Explanation:

For threat remediation in a third-party network, the RADIUS protocol is necessary to communicate with the RADIUS server for details about infected hosts. CoA enables security measures to be enforced based on endpoint information provided by the RADIUS server. Details on this setup can be found in Juniper RADIUS and AAA Documentation.

When deploying threat remediation to endpoints connected through third-party devices, such as switches, the following conditions must be met for proper integration and functioning:
Explanation of Answer A (Support for AAA/RADIUS and Dynamic Authorization Extensions):
Third-party switches must support AAA (Authentication, Authorization, and Accounting) and RADIUS with Dynamic Authorization Extensions. These extensions allow dynamic updates to be made to a session's authorization parameters, which are essential for enforcing access control based on threat detection.
Explanation of Answer B (Connector Gathers MAC Information via API):
The connector uses an API to gather MAC address information from the RADIUS server. This MAC address data is necessary to identify and take action on infected hosts or endpoints.
Explanation of Answer D (Connector Initiates CoA):
The connector queries the RADIUS server for infected host details and triggers a Change of

Authorization (CoA) for the infected host. The CoA allows the connector to dynamically alter the host's access permissions or isolate the infected host based on its threat status.

Threat Remediation via RADIUS: Dynamic remediation actions, such as CoA, can be taken based on information received from the RADIUS server regarding infected hosts.

QUESTION: 23

Exhibit:

Referring to the exhibit, which two statements are correct? (Choose two.)

You cannot secure intra-VLAN traffic with a security policy on this device.
You can secure inter-VLAN traffic with a security policy on this device.
The device can pass Layer 2 and Layer 3 traffic at the same time.
The device cannot pass Layer 2 and Layer 3 traffic at the same time.

Answer(s): B,C

Explanation:

The exhibit provides information about an SRX Series device operating in transparent mode (Layer 2) and Layer 3 routing at the same time. Let's break down the correct answers:
Explanation of Answer B (Secure Inter-VLAN Traffic with a Security Policy):

The SRX device can secure inter-VLAN traffic because it supports security policies for Layer 3 traffic between different VLANs. In this case, traffic moving between different VLANs (i.e., Layer 3 traffic) can be processed and controlled using security policies. Explanation of Answer C (Pass Layer 2 and Layer 3 Traffic Simultaneously):
The SRX device can handle both Layer 2 and Layer 3 traffic simultaneously. In mixed mode, the device is capable of switching traffic at Layer 2 (intra-VLAN) while also routing traffic at Layer 3 (inter-VLAN). This is evident from the global configuration showing transparent bridge mode and Layer 3 interfaces.

Reference:

Mixed Mode Overview: Juniper SRX devices in mixed mode can operate as both a Layer 2 switch and a Layer 3 router, allowing it to pass traffic at both layers simultaneously.

QUESTION: 24

You want to test how the device handles a theoretical session without generating traffic on the Junos security device.
Which command is used in this scenario?

request security policies check
show security flow session
show security match-policies
show security policies

Answer(s): A

Explanation:

The request security policies check command allows you to simulate a session through the SRX device, checking the security policy action that would apply without needing to send real traffic. This helps in validating configurations before actual deployment. For more details, see Juniper Security Policies Testing.

The command request security policies check is used to test how a Junos security device handles a theoretical session without generating actual traffic. This command is useful for validating how security policies would be applied to a session based on various parameters like source and destination addresses, application type, and more.
Explanation of Answer A (request security policies check):
This command allows you to simulate a session and verify which security policies would be applied to the session. It's a proactive method to test security policy configurations without the need to generate real traffic.
Example usage:
bash request security policies check from-zone trust to-zone untrust source 10.1.1.1 destination 192.168.1.1 protocol tcp application junos-https

Security Policies Check: This command provides a way to simulate and verify security policy behavior without actual traffic.
