Examens: Service Provider Routing and Switching, Specialist (JNCIS-SP) (JN0-364)

The Service Provider Routing and Switching track enables you to demonstrate a thorough understanding of networking technology in general and Juniper Networks service provider routing and switching platforms. JNCIS-SP, the specialist-level certification in this track, is designed for networking professionals with beginner to intermediate knowledge of routing and switching implementations in Junos. The written exam verifies your basic understanding of routing and switching technologies and related platform configuration and troubleshooting skills.

This track contains four certifications:

- JNCIA-Junos: Junos, Associate. For details, see  JNCIA-Junos.

- JNCIS-SP: Service Provider Routing and Switching, Specialist. For details, see the sections below.

- JNCIP-SP: Service Provider Routing and Switching, Professional. For details, see  JNCIP-SP.

- JNCIE-SP: Service Provider Routing and Switching, Expert. For details, see JNCIE-SP.
