DP-300 Practice Question: Monitor, configure, and optimize database resources
You are optimizing an Azure SQL Database that uses the Business Critical tier. Which TWO factors affect the maximum log rate?
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
✓
Service level objective (SLO)
The maximum log rate in Azure SQL Database Business Critical tier is determined by the service level objective (SLO) which includes a preset log rate limit, and the number of vCores as part of that SLO. The number of log files does not affect the log rate; log write throughput is governed by the storage performance tied to the SLO. Backup retention period and page compression level have no impact on log rate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Service level objective (SLO)
Why this is correct
Correct. The service level objective (SLO) defines the resource limits, including the maximum log rate.
- ✓
Number of vCores
Why this is correct
Correct. The number of vCores is part of the SLO and directly influences the log rate limit.
- ✗
Backup retention period
Why it's wrong here
Incorrect. Backup retention period affects how long backups are kept but does not impact the log write rate.
- ✗
Number of log files
Why it's wrong here
Incorrect. The number of log files is not a configurable factor; the log rate is governed by the SLO and vCores.
- ✗
Page compression level
Why it's wrong here
Incorrect. Page compression level affects storage size and I/O but not the transaction log write rate.
