A sample answer to question 1

How would you deploy a batch of fifty new laptops so they are ready for users with minimal hands-on time?

I would use zero-touch provisioning with Windows Autopilot where the organisation uses Intune. The supplier or I register the hardware hashes in the tenant, we assign a deployment profile, and when a user or technician switches on the laptop and signs in, it joins Entra ID, enrols in Intune and pulls down policies, applications and updates automatically. I set up an enrolment status page so it does not let the user in until essential apps are installed. In an on-premises environment I would use an MDT or Configuration Manager task sequence to image and install software instead. Before the batch, I would build and test the profile on one or two devices, confirm BIOS versions, drivers and BitLocker escrow, and check the licences. I would label each device, record serials in the asset register, and do a spot check of several against a build checklist. For hand-out I would book users in and brief them on first sign-in and MFA setup.

Common mistake to avoid: Hand-building each laptop; skipping a pilot and a final quality check
