Correct answer & explanation
✓
Business Critical tier with zone redundancy
The Business Critical tier with zone redundancy provides an SLA of 99.995% and automatic recovery from zone-level failures without data loss. The Basic tier does not support zone redundancy. The General Purpose tier with zone redundancy offers a 99.99% SLA. The Hyperscale tier with zone redundancy offers a 99.95% SLA for zone-redundant configurations. Therefore, only the Business Critical tier meets the 99.995% uptime requirement with zone redundancy.
