• IP addressing and subnetting

• Layer 2 and Layer 3 networking concepts

• TCP/IP protocols and characteristics

• Fiber-optic connector types

Domain 2: Junos OS Fundamentals

This domain focuses on the core architecture and operation of the Junos OS. Candidates must understand:

• Junos OS architecture and modular design

• The separation of control and forwarding planes

• Junos OS software components and processes

Domain 3: User Interfaces

This domain covers the various interfaces used to interact with Junos OS devices. Candidates must understand:

• CLI modes and navigation

• Management interfaces and access methods

• Configuration and operational modes

Domain 4: Configuration Basics

This domain covers the fundamental configuration tasks in Junos OS. Candidates must understand:

• Configuration hierarchy and syntax

• Initial device configuration

• Configuration management and file handling

Domain 5: Operational Monitoring and Maintenance

This domain covers operational monitoring and maintenance procedures in Junos OS. Candidates must understand:

• Monitoring tools and commands

Key Concepts Tested in the JN0-106 Exam

OOB Management Interface Configuration

When setting up initial configuration on a Juniper router, the out-of-band (OOB) management interface (typically fxp0.0 or em0.0) must be configured with an IP address to ensure management traffic is isolated from the default routing table (inet.0). This is essential for maintaining management access separate from production traffic.

Authentication Services

Junos OS supports multiple authentication methods for user access. The exam tests knowledge that Junos OS supports local authentication as well as RADIUS and TACACS+ for centralized authentication and accounting services.

Login Classes

Junos OS provides configurable login classes that determine user privileges. The exam assesses understanding of how many login classes are assignable to a user account and how they control access to operational and configuration commands.

Routing and Filtering

Both firewall filters and routing policies are used to control traffic and routing behavior in Junos OS. Candidates must understand the differences between these mechanisms and when to apply each.
