What is the Tanium TCA exam?
The Tanium Certified Administrator exam is the second rung in Tanium's certification program, sitting directly above the entry-level TCO. Tanium's own description: it identifies candidates who can demonstrate the ability to operationalize, maintain, and troubleshoot the platform in a Tanium Cloud environment. The exam runs under SKU TAN-EXAM-TCA and exam code TAN-4000, carries 60 score points across multiple choice and practical application items, runs 110 minutes, costs $250 in the United States, and requires the TCO certification as a prerequisite.
The published candidate profile expects a minimum of two years managing endpoint solutions for servers or workstations: managing users and permissions, performing core functionality and operations and management tasks, maintaining the platform, and performing basic troubleshooting in a Tanium Cloud environment. The recommended course is Tanium Administrator 3.0.
What is the TAN-4000 exam format?
Tanium's TCA exam overview states the format in one sentence: the exam consists of 60 score points total, including multiple choice items and practical application items, with a seat time of 110 minutes. That mix matters. Multiple choice rewards recognizing the right answer; practical application items reward having actually performed the task in a Tanium Cloud environment - which is why the vendor's candidate profile sets a two-year endpoint-management floor.
The certification workflow published in the same document runs in order: previously achieved Tanium Certified Operator certification, the Tanium Administrator 3.0 course, then the Tanium Certified Administrator exam. The required elements are the TCO prerequisite and a passing score on the TCA exam itself; the course is recommended, not mandated.
What does the TCA exam cover?
The published blueprint weights four domains, and the weighting tells you this is a keep-the-platform-healthy exam. Maintain leads at 44%: monitoring tool health, confirming clients are communicating properly, using an action group for a specific deployment type, migrating content from a disabled user, managing computer groups and API tokens, two-person integrity procedures, registering sensors with TDS, and optimizing client settings.
Initial Configuration carries 30%: logical groupings based on network locations and subnets, bandwidth throttling, Tanium client upgrades and installer artifacts, RBAC for user-based roles, when to create computer groups versus filter groups, when and how to create and modify action groups, personas, and client settings. Troubleshoot carries 18%: diagnosing reporting and communication issues, gathering logs or modifying log settings from an endpoint, diagnosing endpoint performance issues, and troubleshooting core platform and RBAC issues. The final 8% is Tanium Platform Advanced Knowledge: advanced question filtering and configuring Tanium integrations.
The document carries Tanium's standard caveat: the blueprint provides general guidelines for content likely to be included, related topics may appear on any specific delivery, and blueprints may change at any time without notice.
| # | Blueprint domain | Weight | Representative published tasks |
|---|---|---|---|
| 1 | Initial Configuration | 30% | Groupings by network location, bandwidth throttling, client upgrades, RBAC for user-based roles, personas |
| 2 | Maintain | 44% | Tool health, client communication, action groups, content migration, API tokens, sensor registration with TDS |
| 3 | Troubleshoot | 18% | Reporting and communication issues, endpoint logs, endpoint performance, core platform and RBAC |
| 4 | Tanium Platform Advanced Knowledge | 8% | Advanced question filtering, Tanium integrations |

Is the TCO really required before the TCA?
Yes - and the exam overview prints it in capitals: PREREQUISITES REQUIRED: TCO Certification. There is no published bypass. The intended path is sequential: earn the entry-level TCO, build administrator experience against the Tanium Administrator 3.0 course material, then sit TAN-4000.
The practical planning note is the two-year validity clock. Both the TCO and TCA are valid for two years, and the TCO recertification rule is the flexible one - TCO holders may recertify by passing any Tanium exam, which means passing the TCA itself keeps the chain alive. Sequence the sittings with the clocks in mind and you avoid paying for a prerequisite renewal at the worst moment.
How much does the TCA exam cost?
The Tanium Candidate Handbook fee table lists the TCA exam at $250 in the United States. Payment is collected by Pearson VUE during registration, at the time of registration. The alternative route is a prepaid voucher: exam voucher SKUs sit on the Tanium Price List and are quoted through your Tanium account team or partner representative, each voucher covers exactly one exam attempt, and vouchers are valid for up to 12 months with no extensions granted.
The full cost picture includes the rules around the fee. Reschedule or cancel at least 48 hours before the appointment or the fee is forfeited, and a no-show forfeits it too. Retakes are full-price attempts on a waiting ladder: 7 days after a first failure, 14 calendar days after the second, and 21 days before the fourth and fifth attempts. Two failed TCA attempts means $750 in exam fees for three sittings.
Can you take the TCA exam at home?
Yes. Tanium's certifications page states its exams are delivered by Pearson VUE and available at authorized testing centers or remotely in an online proctored format, and the Pearson VUE Tanium program page names the two secure delivery methods: a Pearson test center, or OnVUE Online Proctored, where testing occurs from the comfort of your home or office while being monitored by an offsite Pearson live proctor.
The at-home route has published rules. Check-in opens 30 minutes before the appointment, and arriving more than 15 minutes late means the exam cannot be started. All communication with the proctor is in English. You present a current, unexpired government-issued ID with a photo and signature - a passport, driver's license, national or state ID card, or alien registration card - and restricted IDs such as US military IDs cannot be used for online testing. Scheduling runs through the Tanium Career Certifications portal into Pearson VUE, and every candidate accepts Tanium's Candidate Agreement on exam-content confidentiality.
What score do you need to pass, and how long does the TCA last?
Tanium does not publish a passing score. The Candidate Handbook states that Tanium exams are pass/fail, the scores needed to pass are determined through statistical analyses and are subject to change, and passing score requirements are not published because exam questions and passing scores may adjust as exam content changes. Results typically arrive within 24 hours in the candidate portal; pass and the Credly badge follows, miss and you receive section-level performance information.
The retake policy is a ladder: a 7-day wait after the first failed attempt, 14 calendar days after the second, 14 days before the third attempt, and 21 days before the fourth and fifth. Attempts beyond the fifth are case by case through [email protected], and no retakes are permitted beyond the fifth attempt for one calendar year. The credential is valid for two years, and TCA holders recertify by taking the TCA exam - Tanium recommends recertifying at least two months before expiration and makes no exceptions for expired certifications.
How hard is the TCA exam, and what trips candidates up?
The honest answer starts with the format: practical application items do not reward recognition, they reward having done the task. An administrator who has configured RBAC for user-based roles, built action groups for a specific deployment type, and migrated content from a disabled user will recognize the exam's center of gravity; one who has only watched those tasks will not. Tanium's two-year experience floor in the published candidate profile is the vendor pricing that gap.
The second trap is weighting blindness. Candidates who study the platform evenly discover that Maintain alone carries 44% of the blueprint - nearly half the exam lives in tool health, client communication, groups, API tokens, two-person integrity, sensor registration with TDS, and client-setting optimization. The third trap is the prerequisite chain: sitting TAN-4000 with a lapsed or missing TCO makes the attempt worthless regardless of the score. Add the unpublished passing threshold and the 7/14/21-day retake ladder, and the expensive failure mode is always the unplanned one.
The bottom line on the Tanium TCA exam
TAN-4000 is a 110-minute administrator exam with 60 score points split between multiple choice and practical application items, a blueprint that puts 44% of its weight on platform maintenance, a hard TCO prerequisite, a $250 US fee, at-home OnVUE delivery, unpublished passing scores, and a 7/14/21-day retake ladder. Tanium gives you the blueprint and the profile of who the exam is built for; the rest is execution.
If the exam itself is the obstacle - the timeline, the maintenance-domain depth, or the retake math - send your role, your Tanium background, your window, and your deadline. You get an honest feasibility answer against the current exam coverage, and if the engagement makes sense, the sitting is handled end to end with the service fee due only after your pass posts.
