Microsoft Defender for Cloud is one service that answers two different questions: how securely are my resources configured? and is anything attacking the workloads running on them? Keep those two halves separate in your head and this whole topic becomes easy points. The diagram above draws them as two pillars — learn which feature belongs to which.
Pillar one: posture (CSPM)
Cloud security posture management is the assessment half, and it is free and on by default for every subscription. It gives you three things the exam names again and again:
- Secure Score — a single percentage that rates how secure your configuration is. It is a measure of progress: it rises as you fix things, and falls when you add unhardened resources.
- Security recommendations — the prioritized to-do list behind that score. Each one flags a specific weakness (an unencrypted disk, an open port, missing endpoint protection) and the action that hardens it. Remediating recommendations is exactly what pushes Secure Score up.
- The regulatory compliance dashboard — your resources measured against standards such as ISO 27001 and SOC 2, with passing and failing controls listed. (Note the contrast: this is your environment’s compliance; Microsoft’s own platform certifications live on the Service Trust Portal.)
Pillar two: protection (workload plans)
The second pillar actively defends running workloads, and this is the paid layer. Protection is delivered as Defender plans enabled per resource type — Defender for Servers, Defender for Storage, Defender for Databases, and more. Turn on the plan for a resource type and Defender adds threat detection tuned to it, raising threat alerts when it spots suspicious activity.
One workload feature the exam loves is just-in-time (JIT) VM access: management ports like RDP and SSH stay closed, opening only for a short, approved window when an admin actually needs in. That shrinks the attack surface without blocking legitimate work.
It reaches beyond Azure
Defender for Cloud is not limited to resources born in Azure. Through Azure Arc, servers running on-premises or in another cloud can be onboarded and protected from the same dashboard — so hybrid and multi-cloud estates get one posture-and-threats view. If a question stresses “across all environments from one place,” that is the capability being tested.
The one-line map
Split every Defender question by pillar first. Posture words — Secure Score, recommendations, compliance dashboard, free tier — point to CSPM. Protection words — threat alerts, per-resource plans, just-in-time access, paid — point to workload protection. The real exam mixes multiple-choice, true/false, and drag-and-drop formats; the seven samples above are standard multiple-choice, and every explanation carries a “why not the others” so the wrong options teach you as much as the right one.
Updated for AZ-900 (July 2026). The sample questions above are our own work
in the style of the exam — not real exam items. The exam itself is set and marked
by the certification body.
