Cisco DCCOR 350-601 Exam Guide 2026

DCCOR 350-601 — Implementing Cisco Data Center Core Technologies — is the core exam for CCNP Data Center and the qualifying exam for CCIE Data Center. This brief uses the official blueprint, v1.2.

What DCCOR certifies

Data centre infrastructure end to end: the network fabric, compute (UCS and server virtualisation), storage networking, automation, and security. It is a broad exam because the data centre role is broad — you are expected to be competent across all four infrastructure pillars rather than specialised in one.

Exam format

The five domains and their weights

Network and Compute are 50% between them, and adding Storage Network takes the three infrastructure pillars to 70%. Automation and Security share the remaining 30% evenly.

That distribution is a useful corrective. Candidates who come from a routing-and-switching background often over-index on Network and neglect Compute — which is worth exactly as much. UCS, server virtualisation and application high availability are half the infrastructure story here.

Compute is half the infrastructure story

Worth isolating, because it is the single most common preparation error on this exam.

Candidates arriving from a routing and switching background read “data centre” as “data centre networking”. They prepare thoroughly for VXLAN, EVPN and fabric design, then meet a paper where Compute is worth exactly as much as Network — 25% each — and lose a quarter of the exam to material they treated as secondary.

Service profiles deserve particular attention. The idea that server identity and configuration are abstracted from physical hardware is the conceptual centre of UCS, and it underpins a disproportionate share of the compute questions. If you can explain what a service profile is, what a template does, and why pools exist, you have the spine of the domain.

The same discipline applies to Storage Network at 20%. Fibre Channel, FCoE and zoning are unfamiliar to most enterprise network engineers, and a fifth of the exam is a lot to concede to unfamiliarity.

The AI rename, and why it matters

In blueprint v1.2, domain 4 is titled Automation and Artificial Intelligence. Cisco made the identical change to the ENCOR 350-401 blueprint at its own v1.2, where domain 6 carries the same name at the same 15% weighting.

Practically, this is the domain most likely to be stale in older courseware. A 15% domain is roughly one question in seven — enough to matter, and enough that material written against an earlier blueprint will leave a visible gap.

Completing CCNP Data Center

DCCOR is the core exam, and Cisco professional certifications require core plus one concentration. Pass DCCOR and one data-centre concentration exam and CCNP Data Center is complete.

The concentration options cover the specialisms within the track — design, troubleshooting, ACI, and automation among them — so the second exam is where you signal what you actually do. Confirm the current list with Cisco before booking, as available concentrations change.

DCCOR also serves as the qualifying exam for CCIE Data Center. That dual role is worth knowing: the work you put into the core exam is the same work that opens the expert track, so there is no wasted effort if you later go that way.

Common preparation mistakes

Studying without a data centre

The obvious problem with this exam is that most candidates cannot lab it. Nexus switches, fabric interconnects and Fibre Channel fabrics are not home-lab equipment, and that is the single biggest practical obstacle to preparing for DCCOR.

Three workable substitutes:

• Cisco’s simulation and sandbox environments. Cisco publishes lab environments covering data centre platforms, including reservable sandboxes for its management interfaces. Check the current catalogue before paying for third-party rack time.
• Employer kit, out of hours. If your organisation runs UCS or Nexus, a read-only account plus permission to explore a non-production domain is worth more than any course. Most of what is examined is visible without changing anything.
• Documentation for storage. Fibre Channel and FCoE are the hardest to simulate and, fortunately, among the most learnable from reading — zoning logic in particular is conceptual rather than tactile.

Prioritise ruthlessly. If you can get hands on only one thing, make it UCS service profiles. The abstraction of server identity from physical hardware is the conceptual centre of the compute domain, that domain is worth 25% of the exam, and it is the idea candidates most often half-understand from reading alone.

Frequently Asked Questions

What are the DCCOR 350-601 domains?

In blueprint v1.2: Network (25%), Compute (25%), Storage Network (20%), Automation and Artificial Intelligence (15%) and Security (15%).

How long is the DCCOR exam?

120 minutes. It is the core exam for both CCNP Data Center and CCIE Data Center.

What changed in blueprint v1.2?

The automation domain was renamed to Automation and Artificial Intelligence, mirroring the same change Cisco made to the ENCOR 350-401 blueprint at v1.2.

Does DCCOR count toward CCIE?

Yes. Like the other Cisco core exams, DCCOR serves as the qualifying exam for the corresponding CCIE track as well as the CCNP core requirement.
