MS-900 Describe cloud concepts Practice Question
A tenant administrator is advising a department that wants to keep services available during a hardware failure. Cloud concept or benefit best matches this requirement?
⚠ Common exam trap
Watch out — candidates often confuse high availability with disaster recovery or data protection features like DLP, but high availability specifically focuses on minimizing downtime during failures, not on preventing data loss or classifying data.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
High availability
High availability (C) is the correct answer because it directly addresses the requirement to keep services available during a hardware failure. High availability refers to a system's ability to remain operational and accessible despite component failures, typically achieved through redundancy, failover clustering, and load balancing. In Microsoft 365, this is implemented via redundant infrastructure across multiple datacenters and automatic failover mechanisms, ensuring service continuity without manual intervention.
