Cisco 300-615 DCIT: What the Troubleshooting Exam Actually Covers

What 300-615 DCIT Exam Actually Certifies

DCIT is not a "learn data center concepts" exam — it's a troubleshooting exam, full stop. Cisco built it to test whether you can diagnose and fix problems in a data center that's already built, not design or deploy one from scratch. That distinction matters more than it sounds: a candidate who's only ever done greenfield ACI deployments from a runbook can still fail this exam, because DCIT expects you to read symptoms (a VPC that's flapping, an EVPN route that isn't propagating, a UCS blade that won't boot from SAN) and work backward to the root cause.

Passing 300-615 earns you the standalone Cisco Certified Specialist – Data Center Operations certification. It also satisfies the concentration-exam requirement for the full Cisco Certified Network Professional (CCNP) Data Center certification, provided you've also passed the 350-601 DCCOR core exam.

Who 300-615 DCIT Exam Is For (and Who It's Not For)

This exam fits data center network engineers, NOC/operations staff, and TAC-adjacent roles who spend their days keeping an existing Nexus/UCS/ACI environment running rather than architecting new ones. If your job title includes "operations," "support," or "NOC," this is probably the concentration exam that maps most directly to daily work.

It's a poor fit for two groups. First, anyone who hasn't touched Cisco data center gear hands-on — the scenario-based questions assume you've actually sat in front of NX-OS and APIC CLIs under pressure, not just read about them. Second, candidates whose interest is purely ACI policy design or purely automation-and-orchestration; DCIT touches both but goes deep on neither the way DCACI (ACI-specific) or DCNAUTO (automation-specific) do.

Exam Format and Structure

Ninety minutes is tight for a troubleshooting exam. Cisco doesn't publish the exact question count or passing score for this exam — it never has for exams at this level — but expect a mix of straightforward multiple-choice recall questions and longer scenario-based items where you're given a topology, a symptom, and sometimes CLI output, and asked to identify the fault or the next diagnostic step.

The scenario questions are where most people run out of time. It's common to spend two or three minutes parsing a topology diagram and output snippet before you've even read the actual question. If you're used to knowledge-recall exams where you can move fast, budget extra time per question here and don't be surprised if you're watching the clock in the last 15 minutes.

Domains and Topics Covered

These are the official v1.2 domain weightings, current as of Cisco's most recent exam-topics revision:

Network and Compute Platforms together make up half the exam, so this is not primarily an ACI exam or primarily a UCS exam — it's genuinely split. Inside Network, expect OSPFv2/v3, MP-BGP, PIM, FHRP, vPC/LACP, VXLAN EVPN overlays, and a chunk of ACI-specific troubleshooting (fabric discovery, access policies, VMM integration, tenant policies, external connectivity). Compute Platforms covers UCS rack and blade troubleshooting down to chassis/IOM/VIC hardware interoperability and firmware. Storage Network is Fibre Channel-heavy: buffer credit starvation, NPV/NPIV, zoning, FCID. Automation covers EEM, Bash/guest shell on NX-OS, REST APIs, Python, Ansible, Terraform CLI, and Intersight — a noticeably modern list compared to earlier DCIT versions, which is worth knowing if you're studying from an older guide. Management and Operations folds in security topics too: AAA/RBAC across compute, network, and storage; MACsec; port security; and Nexus Dashboard/Intersight integration.

Cost Breakdown

The exam is $300 USD, payable directly through Pearson VUE or redeemable with Cisco Learning Credits if your employer purchases those in bulk. Cisco doesn't publish a separate discounted retake fee — a retake costs the same $300, and Cisco enforces a mandatory waiting period between attempts (five calendar days after a first fail, growing longer after repeated fails) rather than letting you rebook immediately. Regional pricing can vary outside the US; check the exact figure in your Pearson VUE account before registering, since Cisco's published price is the US baseline.

Prerequisites and Eligibility

Cisco does not enforce any formal prerequisite to sit 300-615 — no CCNA, no core exam, nothing gatekeeping registration.  though, this is a professional-level concentration exam, and most candidates who pass it have already cleared 350-601 DCCOR (or have equivalent years of hands-on data center experience). Walking in without that foundation is technically allowed and practically rough — DCCOR builds the baseline NX-OS and ACI knowledge that DCIT assumes you already have and then tests you on breaking and fixing it.

How 300-615 DCIT Exam Is Scored and What Passing Requires

Cisco scores this exam on a scaled range and doesn't publish the passing threshold, the raw number of questions, or a percentage-correct target for any exam at this level — that policy is consistent across the CCNP portfolio, not specific to DCIT. You'll see a pass/fail result immediately at the test center, with a detailed score report available online within 48 hours. The score report breaks performance down by domain, which is more useful for a retake than the pass/fail line itself, since it tells you whether you need to go back to Storage Network or Automation specifically.

Renewal and Recertification

The Cisco Certified Specialist – Data Center Operations credential (and the concentration credit toward CCNP Data Center) is valid for three years from the pass date. Cisco gives you two paths to renew: retake 300-615 itself (or a newer version of it) before expiration, or earn enough Continuing Education (CE) credits through Cisco's CE program — a mix of training, conference attendance, and other qualifying activity — without sitting the exam again. If you're actively working in Cisco data center environments, the CE path is usually less disruptive than re-testing.

How 300-615 DCIT Exam Compares to Its Closest Alternatives

Within the CCNP Data Center track itself, the concentration exam most often cross-shopped against DCIT is 300-620 DCACI (Implementing Cisco Application Centric Infrastructure). DCACI goes deep on ACI policy model and fabric implementation specifically; DCIT touches ACI troubleshooting but spends equal or greater weight on non-ACI Network, Compute, and Storage troubleshooting. If your day job is pure ACI operations, DCACI is arguably the tighter fit. If your job spans UCS, NX-OS, Fibre Channel, and ACI, DCIT matches more of what you actually do.

Outside the Cisco ecosystem, the nearest equivalent is Juniper's JNCIP-DC (exam code JN0-683) — also a 90-minute, Pearson VUE-delivered, troubleshooting-oriented professional data center exam, though it requires a prerequisite certification (JNCIS-DC or JNCIS-ENT) that DCIT does not, and it's built entirely around Junos OS and EVPN-VXLAN IP fabrics rather than Cisco's NX-OS/UCS/ACI stack. The two aren't interchangeable credentials — they validate expertise in different vendor ecosystems — but they occupy the same rung and serve the same hiring conversation for employers running mixed Cisco/Juniper data centers.

 Preparation Timeline

For someone already working daily in a Cisco data center environment with DCCOR-level knowledge, four to six weeks of focused study is a reasonable target, weighted toward whichever domain you touch least at work. Automation is the domain most engineers underprepare for, since Ansible/Terraform/Python scenarios show up more than day-to-day NOC work would suggest. If you're coming in without recent hands-on UCS or Fibre Channel exposure, add two to three weeks specifically for lab time — this exam's scenario questions punish people who've only read about SAN zoning and buffer credits rather than actually troubleshooting them.
