Practice Questions for Juniper JN0-232 Exam


Practice questions for the Juniper JN0-232 (JNCIA-SEC) exam play a critical role in reinforcing your understanding of Junos OS security concepts and SRX Series firewall operations. These questions are designed to closely reflect the real exam format, helping you become familiar with the types of scenarios, technical terminology, and multiple-choice structures you will encounter on exam day. High-quality JN0-232 practice questions focus on key topics such as security policies, NAT behavior, content security, and troubleshooting workflows, allowing you to assess your readiness, identify knowledge gaps, and improve your confidence. When combined with detailed explanations, practice questions not only test your knowledge but also deepen your practical understanding, making them an essential tool for achieving JNCIA-SEC certification success.

Question#1

You must monitor security policies on SRX Series devices dispersed throughout locations in your organization using a 'single pane of glass' cloud-based solution.
Which solution satisfies the requirement?

A. Juniper Sky Enterprise
B. J-Web
C. Junos Secure Connect
D. Junos Space

Explanation:
Junos Space is a management platform that provides a single pane of glass view of SRX Series devices dispersed throughout locations in your organization. It provides visibility into the security policies of the devices, allowing you to quickly identify and respond to security threats. Additionally, it provides the ability to manage multiple devices remotely and in real-time, enabling you to quickly deploy and update security policies on all devices. For more information, please refer to the Juniper Networks Junos Space Network Director User Guide, which can be found on Juniper's website.

Question#2

Which two statements are correct about NAT and security policy processing? (Choose two.)

A. The security policy is evaluated before destination NA
B. The security policy is evaluated after source NA
C. The security policy is evaluated before source NA
D. The security policy is evaluated after destination NA

Explanation:
The packet processing order in SRX with NAT and policies is:
Destination NAT (applies first, for inbound traffic).
Security Policy Evaluation (after destination NAT, before source NAT).
Source NAT (applies last, for outbound traffic).
Option A: Incorrect. Policies are not evaluated before destination NAT.
Option B: Correct. Security policies are evaluated before source NAT but after destination NAT. So in terms of order, policies are processed prior to source NAT.
Option C: Incorrect. Policies are not evaluated before source NAT ― they are evaluated before source NAT is applied.
Option D: Correct. Policies are evaluated after destination NAT.
Correct Statements: B and D

Question#3

What are two Juniper ATP Cloud feed analysis components? (Choose two.)

A. IDP signature feed
B. C&C cloud feed
C. infected host cloud feed
D. US CERT threat feed

Explanation:
The Juniper ATP Cloud feed analysis components are the IDP signature feed and the C&C cloud feed. The IDP signature feed provides a database of signatures from known malicious traffic, while the C&C cloud feed provides the IP addresses of known command and control servers. The infected host cloud feed and US CERT threat feed are not components of the Juniper ATP Cloud feed analysis.
To learn more about the Juniper ATP Cloud feed analysis components, refer to the Juniper Networks Security Automation and Orchestration (SAO) official documentation, which can be found at https://www.juniper.net/documentation/en_US/sao/topics/concept/security-automation-and-orchestration-overview.html. The documentation provides an overview of the SAO platform and an in-depth look at the various components of the Juniper ATP Cloud feed analysis.

Question#4

Which three Web filtering deployment actions are supported by Junos? (Choose three.)

A. Use IP
B. Use local lists.
C. Use remote lists.
D. Use Websense Redirect.
E. Use Juniper Enhanced Web Filtering.

Explanation:

Question#5

Which two user authentication methods are supported when using a Juniper Secure Connect VPN? (Choose two.)

A. certificate-based
B. multi-factor authentication
C. local authentication
D. active directory

Explanation:
"Local Authentication―In local authentication, the SRX Series device validates the user credentials by checking them in the local database. In this method, the administrator handles change of password or resetting of forgotten password. Here, it requires that an user must remember a new password. This option is not much preferred from a security standpoint.
• External Authentication―In external authentication, you can allow the users to use the same user credentials they use when accessing other resources on the network. In many cases, user credentials are domain logon used for Active Directory or any other LDAP authorization system. This method simplifies user experience and improves the organization’s security posture; because you can maintain the authorization system with the regular security policy used by your organization."
