SC-300 exam tips: how to approach it
The most useful SC-300 tip is to learn the handful of distinctions that the questions keep testing, and to read each scenario for the one constraint that selects the answer. Most wrong answers on SC-300 are plausible features applied to the wrong situation: the right service, but the wrong scope, licence or permission type.
Distinctions that decide questions
| Pair | Rule of thumb |
|---|---|
| Delegated vs application permission | A user is present: delegated. A daemon runs alone: application, with admin consent |
| Eligible vs active | Eligible needs activation in PIM; active is in force now |
| System- vs user-assigned managed identity | System ties to one resource; user-assigned is shared and reusable |
| Entra joined vs registered vs hybrid joined | Corporate cloud-only; personal; corporate and in on-premises AD |
| PHS vs PTA | PHS validates in the cloud and survives an on-premises outage; PTA validates on-premises |
| Connect Sync vs Cloud Sync | Full topology and device options versus lightweight cloud-managed agents |
| User risk vs sign-in risk | Compromised account: password change. Suspicious sign-in: MFA |
| Report-only vs enabled | Report-only logs the result without enforcing |
| Entra role vs Azure RBAC role | Directory tasks versus resource tasks |
| Storage vs Log Analytics vs Event Hubs | Cheap archive, query, stream |
Read the scenario for the constraint
Underline words such as least privilege, without a VPN, without helpdesk involvement, minimise administrative effort, automatically, temporary, external. Each narrows the answer. “Automatically” points to dynamic groups, access package expiry, auto-apply on a review or cross-tenant synchronization. “Temporary” points to PIM, a Temporary Access Pass or an expiring package.
Check the licence
Several features need Entra ID P1, P2 or governance licences: dynamic groups, Conditional Access, ID Protection, PIM, access reviews and entitlement management. If a scenario names a licence tier, test your answer against it. Do not memorise a table; learn which feature family each tier unlocks, and confirm in current documentation.
Conditional Access questions
- Remember that all matching policies apply and block wins.
- Check exclusions: emergency access accounts and service accounts are the usual ones.
- Ask whether a policy is in report-only mode before concluding it failed.
- For a policy that does not apply, think of conditions: wrong platform, a client app type, a location, or a user not in scope.
Code snippets
You will meet short KQL queries (SigninLogs, AuditLogs, where, summarize, project) and PowerShell or Microsoft Graph PowerShell commands. You rarely have to write one from nothing; you choose the dropdown values or say what the code returns. Practise by running three or four basic KQL queries on real sign-in logs.
Case studies and yes/no series
On a case study, read the requirements list first, then the questions, and only then the background. On yes/no series, remember that the same scenario may allow different solutions per item; judge each against the requirement, not against the previous one. You usually cannot return to a series once answered.
Time
You have 100 minutes. Do not spend more than two or three minutes on a single item; mark it and move on if the interface allows. For the day itself, see the exam day guide, and for the mechanics see the exam format.
Final week
- Repeat the official practice assessment and compare with your first score.
- Re-run the lab for your weakest domain.
- Take the free practice test and review every answer, including those you got right.
- Read the change log in the study guide so you know what moved on October 28, 2026.
- Rest. The exam rewards clear reading more than cramming.
