DP-300 Configure and manage automation of tasks Practice Question
You are automating the creation of Azure SQL Databases using ARM templates. You need to ensure that the databases are created with the 'Hyperscale' service tier and with 'ZoneRedundant' enabled. Which ARM template property should you set?
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
✓
Set 'sku' to 'HS_Gen5_2' and 'properties.zoneRedundant' to true.
In ARM templates for Azure SQL Database, the 'sku' property defines the service tier and performance level. For Hyperscale, the 'sku' name is 'HS_Gen5_2' (Gen5, 2 vCores) and the 'sku.tier' is 'Hyperscale'. The 'zoneRedundant' property is set under 'properties' to true for zone redundancy. Option B is incorrect because 'requestedServiceObjectiveName' is used for DTU-based tiers, not vCore-based Hyperscale. Option C is incorrect because 'edition' is not a valid ARM template property; the tier is specified through 'sku.tier'. Option D is incorrect because 'maxSizeBytes' only sets the maximum database size, not the service tier.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set 'sku' to 'HS_Gen5_2' and 'properties.zoneRedundant' to true.
Why this is correct
The 'sku' property specifies the service tier, and 'zoneRedundant' is a property of the database.
- ✗
Set 'requestedServiceObjectiveName' to 'HS_Gen5_2' and 'zoneRedundant' to true.
Why it's wrong here
'requestedServiceObjectiveName' is for DTU-based tiers, not for vCore-based tiers.
- ✗
Set 'edition' to 'Hyperscale' and 'zoneRedundant' to true.
Why it's wrong here
'edition' is not a valid property in ARM templates for Azure SQL Database.
- ✗
Set 'maxSizeBytes' to a value and 'zoneRedundant' to true.
Why it's wrong here
'maxSizeBytes' does not define the service tier.
