Cisco 400-007 SPAS Exam Questions & Knowledge Points

400-007: Cisco Certification Exam Overview

Why This Exam Matters for SP Engineers

The Cisco 400-007 exam — formally known as Implementing Cisco Service Provider Advanced Solutions (SPAS) — sits within the CCNP Service Provider certification track as a concentration exam. It targets engineers who operate, design, or troubleshoot large-scale carrier-grade networks. Unlike enterprise-focused certifications, this exam demands fluency in technologies that underpin the global internet backbone: Multiprotocol BGP, MPLS label switching, Segment Routing, and advanced VPN architectures. If you work at an ISP, a telecom operator, or a hyperscaler's WAN division, this exam validates precisely the skill set you use daily.

What the Exam Actually Tests

The blueprint spans several dense technical pillars. You will encounter deep questions on MP-BGP route manipulation (communities, AS-Path prepending, route reflector topologies), MPLS LDP and RSVP-TE tunnel engineering, Layer 3/2 VPN services including EVPN and VPLS, and the increasingly critical Segment Routing (both SR-MPLS and SRv6) paradigms. Additional weight is given to QoS policy implementation across SP cores, multicast replication in provider networks, and IPv6 transition mechanisms such as 6PE/6VPE. Automation topics — RESTCONF, NETCONF, and YANG modeling — have also gained prominence in recent exam revisions.

Where Candidates Struggle Most

The difficulty curve of this exam is steep and uneven. Foundational BGP path selection or basic MPLS label operations are manageable with solid CCNP-level preparation. However, multi-layered scenario questions — such as diagnosing route leakage across three VRFs with overlapping route targets, or selecting the correct SRv6 micro-SID behavior for traffic steering — separate prepared candidates from truly expert ones. Many test-takers underestimate the troubleshooting-style items that present partial CLI outputs and require you to identify the single misconfiguration among several plausible distractors.

A Practical Study Path

Rather than reading cover to cover, anchor your preparation around lab practice. Build an MPLS core in EVE-NG or GNS3 with at least three PE routers, then layer L3VPN, EVPN, and Segment Routing policies on top. Focus two-thirds of your study hours on BGP advanced attributes and MPLS/VPN interactions, as these account for the majority of scenario questions.
