Study Azure AZ-305 Business Continuity: key concepts, common traps, and exam decision cues.
This chapter is where AZ-305 tests whether you can match the business tolerance for downtime and data loss to the right Azure protection pattern. The exam does not reward candidates for naming every resilience feature they know. It rewards candidates who can tell the difference between backup, disaster recovery, and high availability, then choose the least heavy design that still satisfies the recovery target.
Microsoft currently weights this skill area at 15-20% of the exam.
