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
✓
DatabaseConnections
The DatabaseConnections metric shows the number of connections to the DB instance. Option B is wrong because FreeableMemory measures available memory, not connections. Option C is wrong because CPUUtilization measures CPU usage, not connections. Option D is wrong because DiskQueueDepth measures disk I/O.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
DatabaseConnections
Why this is correct
The DatabaseConnections metric directly provides the number of current connections, which can be compared to the maximum connections to determine threshold breaches.
- ✗
FreeableMemory
Why it's wrong here
Freeable memory is not related to connection count.
- ✗
CPUUtilization
Why it's wrong here
CPU utilization does not indicate the number of database connections.
- ✗
DiskQueueDepth
Why it's wrong here
Disk queue depth measures pending disk operations, not connections.
