The Complete Troubleshooting Series

372,76 zł

All three troubleshooting field manuals in a single checkout: CCNA 200-301, CCNP ENCOR 350-401, and CCNP ENARSI 300-410.

The series is built to be read as one arc. CCNA walks the OSI stack and teaches you to bisect. ENCOR reorganizes around exam domains and asks why the protocol behaves the way it does. ENARSI throws away the map entirely and starts from the symptom, the way real outages arrive.

Reference codes stay stable across all three. OSPF-ADJ-03 is the same fault at CCNA, at ENCOR, and inside an ENARSI symptom fan — same code, three altitudes. Eleven codes bridge ENCOR and ENARSI. That cross-referencing only works when you own the rungs above and below.

What you get:

  • CCNA 200-301 v1.1 — 55 pages, 28 faults
  • CCNP ENCOR 350-401 v1.2 — 47 pages, 33 faults
  • CCNP ENARSI 300-410 v1.1 — 33 pages, 24 faults

Three PDFs, one download. Aligned to current blueprints as of 2026.
