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
Options A, D, and E are correct. DatabaseConnections can indicate a memory leak if connections are not closed, consuming memory. SwapUsage indicates memory pressure when physical memory is insufficient. FreeableMemory shows available memory; a decreasing trend may suggest a leak. Option B is incorrect because CPUUtilization is not a direct memory metric. Option C is incorrect because ReadIOPS relates to I/O operations, not memory.
