DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Which TWO actions should you take to achieve high availability for an Azure SQL Managed Instance with a 99.99% SLA? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Business Critical service tier.
To achieve the 99.99% SLA for Azure SQL Managed Instance, you must use the Business Critical service tier (which provides local redundancy) and deploy the instance as zone-redundant (which protects against zone failures). Option A (automated backups with long-term retention) is for data durability and recovery, not availability. Option D (geo-replication) is for disaster recovery, not high availability within a region. Option E (General Purpose) offers a lower SLA (99.99% only with zone redundancy, but still not the highest available; typically 99.99% is achieved with Business Critical and zone redundancy). Therefore, B and C are the correct choices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable automated backups with long-term retention.
Why it's wrong here
Backups do not affect the SLA.
- ✓
Use Business Critical service tier.
Why this is correct
Business Critical provides the highest SLA within a region.
- ✓
Deploy the instance as zone-redundant.
Why this is correct
Zone-redundant deployment is required for 99.99% SLA.
- ✗
Configure geo-replication to a secondary region.
Why it's wrong here
Geo-replication is for DR, not HA within the same region.
- ✗
Use General Purpose service tier.
Why it's wrong here
General Purpose offers 99.95% SLA, not 99.99%.
