7. Routing Policy & Firewall Filters

DOMAIN DESCRIPTIONS

    1. Networking Fundamentals

• Essentials such as collision/broadcast domains, routers/switches, Ethernet, Layer 2/3 addressing, IPv4/IPv6, subnetting, CoS, and protocol types (connection-oriented vs connectionless).

    2.Junos OS Fundamentals

• Core architecture components include the control vs forwarding plane, routing engine, PCC, traffic processing, and exception handling.

    3. User Interfaces

• Command-line interface (CLI) modes, navigation, help usage, candidate vs active configurations, rollbacks, configuration file management, and basic J-Web usage.

    4. Configuration Basics

• First-time setup, system services like NTP, SNMP, system logging, user authentication, configuration archival, and rescue configs.

    5. Operational Monitoring & Maintenance

• Use of show and monitor commands, interface stats/errors, diagnostic tools (ping, traceroute, SSH), Junos upgrades, shutdown, and root recovery.

    6. Routing Fundamentals

• The difference between routing vs forwarding tables, static routing, route preference, and use cases for dynamic routing protocols.

    7. Routing Policy & Firewall Filters

• Policy structure, match/action criteria, import/export policy flow, default routing policies, and IPv4 unicast RPF.

PREPARATION STRATEGY

1. Begin with the exam objectives document to guide your study.
2. Use Juniper’s Introduction to the Junos OS or networking fundamentals courses for structured learning.
3. Leverage Juniper's free hands-on platform called vLabs, along with Open Learning modules for labs and CLI practice.
