An e-commerce user wants to optimize the purchased elastic cloud server to meet the cost- saving needs of the enterprise. Which of the following statements about optimization methods are correct?…

Question

Options

• AContinuously monitor and measure utilization for optimization opportunities
• BRefer to the operation and maintenance historical monitoring data to reasonably determine the
• CDetermine the number of servers based on historical and real-time operation and maintenance
• DBased on the operation and maintenance statistics, identify and shut down unused resources,

• A
  71% (30)
• C
  29% (12)

Explanation

Options A, B, and D are correct because they each represent a complete, actionable cost-optimization strategy: continuous monitoring (A) catches inefficiencies as they emerge, leveraging historical maintenance data (B) enables right-sizing decisions grounded in real usage patterns, and using operational statistics to identify and shut down unused resources (D) directly eliminates unnecessary spending.

Option C is the distractor because it proposes determining only the number of servers based on operational data, which is too narrow an approach. Cost optimization requires evaluating resource type, size, and utilization levels, not just server count, and simply adjusting quantity without addressing idle or underused resources can still result in wasteful spending.

Memory tip: Think of the correct answers as a complete cycle: observe (A), analyze history (B), and act on findings (D). C breaks the cycle by stopping at a single metric, server count, rather than taking the broader, more effective action of eliminating unused resources entirely.
