JN0-335 Dumps - Security, Specialist (JNCIS-SEC) Practice Exam Questions

Earning the JNCIS-SEC boosts your credibility as a security professional specializing in Juniper technologies. Certified professionals are often preferred for roles such as network security engineers, SOC analysts, and firewall administrators, and many report salary bumps post-certification.

This exam is ideal for IT professionals with intermediate knowledge of network security, especially those working with SRX Series devices. If you're already familiar with Junos OS and want to validate your skills in intrusion prevention and advanced firewall configuration, this certification is for you.

The exam covers:

• Security zones and policies
• Unified Threat Management (UTM)
• Intrusion Detection and Prevention (IDP)
• Security Director
• Advanced NAT and IPsec VPNs

    These topics reflect real-world enterprise security practices using Juniper Networks.

Unlike vendor-neutral certifications like CompTIA Security+, JNCIS-SEC dives deep into Juniper-specific implementations, giving you hands-on expertise in SRX firewall technologies—a huge advantage if you're working in or planning to join a Juniper-based environment.

The certification is valid for three years. During this period, you can maintain your status by retaking the exam or advancing to a higher-level certification like JNCIP-SEC.

The JN0-335 is a multiple-choice exam administered by Pearson VUE. It typically consists of 65 questions with a time limit of 90 minutes. The passing score is not publicly disclosed but is scaled based on difficulty.

While not mandatory, it's strongly recommended to first complete the JNCIA-SEC (JN0-231). This foundational knowledge ensures you understand basic Junos OS operations and security fundamentals.
