Memory ___________ and leaks are critical issues that can severely impact application performance.

Question

Options

• Aexpansion
• Bupgrades
• Ccompression
• Dthrashing

• A
  4% (1)
• C
  4% (1)
• D
  91% (21)

Explanation

Memory thrashing (D) is the correct fill-in because thrashing and leaks are a classic pair of critical memory issues - thrashing occurs when a system spends more time swapping data between RAM and disk than executing actual work, causing severe performance degradation that pairs naturally with the concept of memory leaks.

• A (expansion) is wrong because "memory expansion" simply means adding more RAM - it's a solution, not a problem.
• B (upgrades) is wrong for the same reason; upgrading memory is a hardware improvement, not a performance issue.
• C (compression) is wrong because memory compression is a technique used by operating systems to fit more data in RAM - again, a feature, not a critical issue.

Memory tip: Think "thrash and leak" as a rhyming pair - both are things going wrong with memory (thrashing wastes CPU cycles on excessive paging; leaking wastes memory that's never freed), making them natural exam companions.
