]]>

The 350-601 DCCOR exam, formally Implementing and Operating Cisco Data Center Core Technologies, is Cisco’s core paper for the CCNP Data Center and CCIE Data Center tracks. Engineers arriving from the enterprise side usually assume it is a routing and switching exam with a few storage questions attached. The blueprint says otherwise. Network is 25% of the paper, and compute is also 25%. Storage network takes another 20%. That means three quarters of the exam sits in territory an enterprise engineer has often never touched: UCS chassis, service profiles, Fibre Channel zoning and VSANs. Automation and artificial intelligence takes 15%, and security the final 15%. This article breaks down every domain, what the automation content now includes, how the exam feeds three separate credentials at once, and how to sequence preparation so the unfamiliar half does not ambush you two weeks before the exam.

What Is the 350-601 DCCOR Exam?

The 350-601 DCCOR exam is Cisco’s data centre core exam, running 120 minutes with 90 to 110 questions and costing $400 USD through Pearson VUE. Passing it earns the Cisco Certified Specialist – Data Center Core credential outright, and the same pass satisfies the core requirement for both CCNP Data Center and CCIE Data Center.

That triple role is unusual and worth understanding before you book. One exam, three outcomes: a standalone specialist credential, the core half of a professional certification, and the written qualification for an expert track. It also counts toward recertification, so it has value even to engineers who already hold the professional credential.

Version and language

Cisco lists the exam as DCCOR v1.1 on its own current exam page, and offers it in English and Japanese. Cisco introduced minor updates to the CCNP Data Center certification and its specialist certifications in May 2025, so any study resource that predates that should be checked against the current objectives rather than trusted outright. The fee can also be settled with Cisco Learning Credits rather than a card payment, which matters when an employer is funding the attempt.

The full objective set is published on the official DCCOR exam page, and registration runs through Pearson VUE for Cisco.

What Is on the DCCOR Blueprint?

DCCOR splits across five domains, and no domain is small. The lightest two carry 15% each, which on a 100 question paper still means roughly fifteen questions apiece. There is no domain you can safely write off, and that is the single biggest planning difference between this exam and most professional-level papers.

The weightings below are where a study plan is actually built. Note that the pass mark is variable rather than a fixed percentage, so a strong showing in one domain does not reliably rescue a weak one.

Domain Weight Core content
Network 25% OSPFv2 and OSPFv3, MP-BGP, PIM, FHRP, RSTP+, LACP, vPC, VXLAN EVPN, ACI fabric and access policies, packet flow, telemetry, Nexus Dashboard
Compute 25% UCS rack servers and blade chassis, pools, policies and templates, SAN connectivity, server pools and boot policies, UCS-X in Intersight Managed Mode
Storage Network 20% Fibre Channel fabric initialisation, port channels, FCID, CFS, zoning, FCNS, device alias, NPV and NPIV, VSAN, NFS and iSCSI
Automation and Artificial Intelligence 15% EEM, Scheduler, Bash and Guest Shell, NX-API and REST, on-box Python, Ansible, POAP, Terraform CLI, Intersight, AI-enabling network technologies
Security 15% AAA and RBAC across all three layers, ACI contracts and microsegmentation, first-hop security, MACsec, port security, fabric binding

The complete objective list sits on the 350-601 exam syllabus, and it is worth reading in full before committing to a schedule.

Why Does Compute Carry as Much Weight as Network?

Compute carries 25% of DCCOR, exactly matching the network domain, because a Cisco data centre is a converged system rather than a network with servers attached. UCS is not peripheral equipment in this exam. Service profiles, pools and templates are examined at the same depth as routing protocols, and candidates who treat compute as revision material fail on a quarter of the paper.

The domain covers both rack servers and blade chassis, and the examinable work is configuration abstraction: how a service profile decouples identity from hardware, how pools supply MAC addresses, WWNs and UUIDs, and how templates keep hundreds of servers consistent. UCS-X in Intersight Managed Mode extends the same thinking into a cloud-managed control plane.

Where network engineers struggle

  • Treating a service profile as a config file rather than as a movable server identity.
  • Underestimating SAN connectivity inside the compute domain, which overlaps with the storage domain and is tested from both sides.
  • Skipping firmware impact, since the exam asks which updates on B-Series and C-Series servers are disruptive.
  • Ignoring backup and restore, which appears as compute configuration management rather than as a separate topic.

What Does the Network Domain Cover Beyond Routing?

The network domain is 25% of DCCOR and reaches well past traditional routing. It does include OSPFv2, OSPFv3, MP-BGP, PIM and first-hop redundancy, but the distinguishing content is overlay and fabric: VXLAN EVPN, ACI fabric setup, access policies and virtual machine manager integration, plus the packet-flow reasoning that ties them together.

VXLAN EVPN is the piece enterprise engineers most often meet for the first time here. Building a layer two segment across a routed underlay changes how you think about flooding, learning and failure domains, and the exam expects you to reason about unicast, multicast and broadcast behaviour inside that model rather than recite a configuration.

The overlay encapsulation itself is specified in IETF RFC 7348, and reading the header format once makes the troubleshooting questions considerably easier.

Operations content inside the network domain

The domain also carries the operational half of the job: configuration management, infrastructure monitoring with NetFlow and SPAN, streaming telemetry, and the capabilities of Nexus Dashboard. Cisco has folded AI-assisted monitoring into this material, so the questions ask what a platform surfaces and why, not just how to enable a feature.

Cloud service and deployment models appear here too, referenced to a specific standards document rather than to a vendor definition.

“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”

Peter Mell and Tim Grance, authors of NIST Special Publication 800-145

That definition is the one the syllabus points at, and the NIST cloud definition is short enough to read in ten minutes.

How Deep Does the Storage Network Domain Go?

Storage network is 20% of DCCOR and goes deeper into Fibre Channel than most candidates expect. Switch fabric initialisation, port channels, FCID assignment, Cisco Fabric Services, zoning, the name server, device aliases, NPV and NPIV, and VSANs are all named objectives, and they are tested as operational knowledge rather than as terminology.

Fibre Channel behaves nothing like Ethernet, and that is the point of the domain. The fabric assigns addresses, the name server distributes them, and zoning decides who may talk to whom. An engineer who understands why a fabric login sequence matters will answer these questions comfortably; one who has only memorised the command syntax will not.

The IP storage half

NFS and iSCSI appear as concept-level objectives rather than configuration ones, which is a reasonable reflection of how mixed most real data centres now are. You need to be able to say where each fits and what it costs you, not build one from scratch.

Monitoring appears again here, with SPAN and Nexus Dashboard applied to the storage fabric. That repetition across three domains is deliberate: Cisco is testing whether you can apply one operational toolkit across network, compute and storage rather than learning three separate ones.

What Did the Automation and AI Domain Add?

Automation and artificial intelligence is 15% of DCCOR and is the domain that has changed most. It now spans on-box automation, external orchestration and a genuinely new requirement: describing the high-performance network technologies that make AI workloads viable inside data centre infrastructure.

The on-box half is familiar Cisco territory. Embedded Event Manager, the Scheduler, Bash Shell and Guest Shell on NX-OS, on-box Python, and the NX-API REST interface with JSON and XML encodings all appear as implementation objectives, meaning you should be able to use them rather than describe them.

The orchestration half

The evaluation objectives name a specific toolset: Ansible, Python, POAP, Nexus Dashboard, PowerShell, Terraform CLI and Intersight. The verb is evaluate rather than implement, so the exam wants you to pick the right tool for a scenario. Knowing that the Ansible project is agentless and idempotent, for example, is what makes a scenario question answerable.

The AI infrastructure objective is the newest material of all, and it is descriptive rather than hands-on. What matters is understanding why AI training traffic stresses a fabric differently from ordinary east-west traffic, and which fabric characteristics address that. The Cisco data centre AI article covers where that thinking leads next.

Which Security Topics Appear Across All Three Layers?

Security is 15% of DCCOR and is deliberately spread across network, compute and storage rather than isolated in one place. Authentication, authorisation and accounting with role-based access control appears in all three, which is the domain’s organising idea: the same access model applied consistently across a converged stack.

On the network side the objectives name ACI contracts and microsegmentation, first-hop security features, keychain authentication and MACsec. Contracts are the conceptual centre here, because ACI inverts the usual model: nothing communicates until a contract permits it, which is the opposite default from a traditional VLAN.

Compute and storage security

Compute security is narrower, covering AAA and RBAC within UCS management. Storage adds port security and fabric binding on top of AAA and RBAC, which are the mechanisms that stop an unauthorised device or switch from joining a Fibre Channel fabric.

Because the domain is thin in each individual place but present everywhere, the efficient way to study it is alongside each of the other domains rather than as a block at the end.

Does DCCOR Lead to CCNP or CCIE Data Center?

Both, and to a third credential as well. Passing 350-601 earns Cisco Certified Specialist – Data Center Core immediately. It also serves as the core exam for CCNP Data Center, which is completed by adding one concentration exam, and as the written qualification for CCIE Data Center, which is completed by passing the lab.

One 350-601 DCCOR pass leads to three outcomes: Cisco Certified Specialist Data Center Core, CCNP Data Center and CCIE Data Center

That structure changes how the exam should be approached. If your goal is CCNP, DCCOR is half the work and the concentration exam should be chosen for your actual job. If your goal is CCIE, DCCOR is the entry ticket to a much longer road, and the depth you build now pays off later rather than being enough on its own.

Choosing what comes next

The concentration options cover data centre design, infrastructure troubleshooting, ACI implementation and automation. A useful rule is to pick the concentration covering the work you do least well rather than the one covering what you already do daily, since the core exam has already validated the shared ground. A detailed look at the core exam’s own topics sits in this 350-601 exam topics breakdown.

How Should You Sequence a DCCOR Study Plan?

A DCCOR plan should start with the domain you know least, not the one you know best, because the exam’s pass mark is variable and no domain is small enough to sacrifice. Three to five months is realistic for a working engineer. The sequence below front-loads the unfamiliar half.

  1. Audit yourself honestly against the five domains first, because an enterprise engineer usually finds compute and storage network unfamiliar while a storage specialist finds the overlay material harder, and the plan should start wherever the gap is widest.
  2. Spend the first block on compute, learning how a service profile decouples server identity from hardware and how pools and templates keep a fleet consistent, since this is 25% of the paper and the least transferable from enterprise work.
  3. Move to storage network next and learn Fibre Channel as its own model rather than as Ethernet with different names, focusing on fabric initialisation, zoning and the name server.
  4. Take the network domain third, concentrating on VXLAN EVPN and ACI rather than on the routing protocols you already know, and reason through unicast, multicast and broadcast behaviour in an overlay.
  5. Cover automation by actually running the tools, using on-box Python and the NX-API against a sandbox rather than reading about them, and be ready to justify choosing one orchestration tool over another.
  6. Fold security into each domain as you finish it rather than saving it for the end, since AAA and RBAC recur in all three layers and are far easier to remember in context.
  7. Finish with full timed papers at 120 minutes, reviewing every wrong answer against the objective it came from so weak domains surface before exam day rather than during it.

Frequently Asked Questions

How many questions are on the 350-601 DCCOR exam?

DCCOR carries 90 to 110 questions in 120 minutes. The count varies between forms, so plan for roughly 70 seconds per question if you want time left to review anything you flagged.

How much does the DCCOR exam cost?

The fee is $400 USD. Cisco also accepts Cisco Learning Credits for the exam, which is often the simpler route when an employer is funding the attempt rather than reimbursing it.

What is the passing score for 350-601?

The pass mark is variable, sitting at roughly 750 to 850 out of 1000 depending on the form. Because it is not a fixed percentage, writing off a whole domain is far riskier than it looks.

Which DCCOR domain carries the most weight?

Network and compute tie at 25% each, followed by storage network at 20%. Automation and artificial intelligence and security each carry 15%, so no domain is small enough to ignore safely.

Does DCCOR count toward CCIE Data Center?

Yes. The same pass satisfies the core requirement for CCNP Data Center and serves as the written qualification for CCIE Data Center, and it earns Cisco Certified Specialist – Data Center Core in its own right.

Is DCCOR harder for enterprise network engineers?

Usually, because compute and storage network together are 45% of the paper and neither maps onto enterprise routing and switching work. Engineers from a storage or server background often find the overlay content harder instead.

What automation tools does the exam name?

The objectives name EEM, the Scheduler, Bash and Guest Shell, on-box Python, the NX-API REST interface, Ansible, POAP, Nexus Dashboard, PowerShell, Terraform CLI and Intersight. Most are evaluated by fit rather than by syntax.

What languages is the exam offered in?

English and Japanese. Both deliver the same blueprint under the same 120 minute limit, and registration for either runs through Pearson VUE.

How long does DCCOR preparation take?

Three to five months is realistic for a working engineer studying part time. The variable is how much of the compute and storage material is genuinely new, since that half drives most of the timeline.

Does passing DCCOR renew existing certifications?

Yes, the exam can be used toward recertification. That makes it worth considering even for engineers who already hold the professional credential and simply need to keep it current.

Conclusion

DCCOR is not a networking exam with extras bolted on. Compute matches network at 25%, storage network adds another 20%, and the automation domain now reaches into AI infrastructure. The blueprint is telling you plainly that Cisco treats the data centre as one converged system and expects you to do the same.

The practical route through it is to start where your gap is widest rather than where you are comfortable, learn Fibre Channel on its own terms, treat VXLAN EVPN and ACI as the network content that actually differentiates this exam, and run the automation tools instead of reading about them. Fold security in as you go. Working through the published objectives domain by domain is the fastest way to find out which quarter of the paper you have been quietly avoiding.
