What the OTCA actually examines: four Linux Foundation domains led by the API and SDK at 46 percent, the Collector pipeline rules that turn into questions, the debugging objectives most candidates leave until last, and a hands-on preparation order for a 90 minute, 60 question exam.
Four year-stamped names, one credential, and a duration most study pages get wrong. What the Qlik Sense System Administrator exam tests on a Windows site, and what it leaves to Qlik Cloud.
An infrastructure engineer weighing up an AI credential needs one answer first: is it written for me? Here is the experience Nutanix assumes, and a way to test yourself against it.
Servers, identity providers and moving deployments between environments, named task by named task: that is the Analytics-Arch-201 objective list.
Vector embedding, fine tuning and task-specific language models are examinable topics on this credential, sitting in its heaviest domain. Most study material still describes the syllabus that came before them.
Fitting a model accounts for just over half this paper. The rest is the work either side of the fit, and those are the domains an analyst is least likely to have picked up informally. Here is how the five domains divide, and why input preparation and model measurement should be studied as one subject.
Native Apps is the SnowPro Specialty exam that treats you as a software vendor rather than a data professional. Manifests, setup scripts, execution rights, release channels and Marketplace listings carry the paper, and two thirds of the marks sit in the two domains that assume you have actually shipped something.
The capabilities are the same and the labels are not. Google has confirmed that this exam was updated for the move from Vertex AI to Gemini Enterprise Agent Platform, which means the component names in last year’s study notes are the wrong answers now.
On most protocol exams architecture is the biggest domain. On MCPA it is the smallest at 14 percent, while running a tool call and authorising it take half the marks between them. Sixty questions, 120 minutes, 75 percent, and a specification published as dated revisions rather than numbered releases.
Sixty correct answers from seventy-five, across six domains weighted within five points of each other. There is no topic you can write off, and the biggest one is retrieval rather than prompting.
