HCT Performance Optimization

Question 1

What is the first step in performance optimization?

Accepted Answer

Establish baseline measurements and identify bottlenecks

Answer

Upgrade all hardware immediately

Answer

Add more resources without analysis

Answer

Optimize everything simultaneously

Question 2

Why is monitoring important for performance management?

Accepted Answer

It provides real-time visibility into system behavior and early warning of issues

Answer

It is only needed during initial setup

Answer

It uses too many resources to be practical

Answer

It only benefits large-scale systems

Question 3

What is the 80/20 rule as applied to performance optimization?

Accepted Answer

80% of performance gains come from optimizing 20% of the code or configuration

Answer

Spend 80% of time optimizing and 20% testing

Answer

Optimize 80% of components and ignore 20%

Answer

Performance should be 80% of the project budget

Question 4

When should performance testing be conducted?

Accepted Answer

Throughout the development lifecycle and before major releases

Answer

Only after receiving user complaints

Answer

Once during initial deployment only

Answer

Only for applications with more than 1000 users

Question 5

What is capacity planning?

Accepted Answer

Predicting future resource needs based on growth trends and requirements

Answer

Buying maximum resources upfront

Answer

Only planning for current usage levels

Answer

Waiting until resources are exhausted to add more

Question 6

How do you determine if an optimization was successful?

Accepted Answer

Compare post-optimization metrics against the established baseline

Answer

Rely on subjective user feedback

Answer
