JN0-231 Juniper Security-Associate (JNCIA-SEC) Free Practice Exam Questions (2025 Updated)

The number of concurrent Secure Connect user licenses that an SRX Series device has by default is 2. Secure Connect is a feature of Juniper SRX Series devices that allows you to securely connect to remote networks via IPsec VPN tunnels. Each SRX Series device comes with two concurrent Secure Connect user licenses by default, meaning that it can support up to two simultaneous IPsec VPN connections. For more information, please refer to the Juniper Networks SRX Series Services Gateways Security Configuration Guide, which can be found on Juniper's website.

For the UTM feature profile to take effect, it must be associated with a security policy and a UTM policy. The security policy defines the traffic flow and the actions that should be taken on the traffic, while the UTM policy defines the security features to be applied to the traffic, such as antivirus, intrusion prevention, and web filtering. The UTM feature profile provides the necessary configuration for the security features defined in the UTM policy.

Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References:

Understanding UTM (Unified Threat Management) Features on SRX Devices:UTM is a security framework available on Juniper SRX Series devices that integrates multiple security features to protect against various threats. UTM functionalities are focused on advanced traffic inspection, content management, and threat prevention.

Explanation of Each Option:

Option A: Antivirus

UTM on SRX Series devices includes an antivirus feature that scans traffic for malware and viruses.

This feature is implemented using either:

Sophos Antivirus: A cloud-based solution.

Kaspersky Antivirus: A local database-based solution.

The antivirus feature detects and blocks malicious files, providing robust malware protection.

Correct.

Option B: NAT

Network Address Translation (NAT) is a fundamental networking feature on SRX devices but is not part of the UTM suite.

NAT is used to translate private IP addresses to public IP addresses and does not provide traffic filtering or threat management.

Incorrect.

Option C: IDP (Intrusion Detection and Prevention)

IDP is a separate feature on SRX devices for detecting and mitigating intrusions, but it is not part of the UTM framework.

IDP focuses on identifying malicious traffic patterns and blocking threats at the network level, whereas UTM focuses on content inspection and filtering.

Incorrect.

Option D: Content Filtering

Content filtering is a key UTM feature that blocks or allows traffic based on URL categories, keywords, and custom filtering rules.

This feature is used to restrict access to inappropriate or harmful websites and manage user behavior.

Correct.

UTM Features on SRX Devices Include:

Antivirus: Scans and blocks malware in real time.

Content Filtering: Manages access to websites and controls internet usage.

Web Filtering: Enforces policies on web content based on URL categories.

Spam Filtering: Blocks spam emails.

Juniper Security Reference:

Refer to the Juniper UTM Documentation for detailed configuration and feature details.

The default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel is 5 seconds. DPD is a mechanism that enables the IPsec device to detect if the peer is still reachable or if the IPsec VPN tunnel is still active. The DPD interval determines how often the IPsec device sends DPD packets to the peer to check the status of the VPN tunnel. A value of 5 seconds is a common default, but the specific value can vary depending on the IPsec device and its configuration.

The two statements that are correct about IPsec security associations are that they are bidirectional and that they are established during IKE Phase 2 negotiations. IPsec security associations are bidirectional, meaning that they provide security for both incoming and outgoing traffic. IPsec security associations are established during IKE Phase 2 negotiations, which negotiates the security parameters and establishes the security association between the two peers. For more information, please refer to the Juniper Networks IPsec VPN Configuration Guide, which can be found on Juniper's website.
