Questions

Answer the following questions to test your knowledge of this chapter:

1. What is the primary goal of ergonomics in JVM tuning?
   1. Minimizing code compilation time
   2. Automatically adjusting JVM configuration based on runtime characteristics
   3. Maximizing heap size for all applications
   4. Disabling garbage collection for enhanced performance
2. Which GC is often chosen by ergonomics as the default for single-processor systems or when memory is limited?
   1. Serial GC
   2. Parallel GC
   3. G1 GC
   4. ZGC
3. In the context of garbage collection, what does “multi-mapping” refer to?
   1. Multiple mapping of virtual memory addresses to physical memory
   2. The use of multiple garbage collection algorithms simultaneously
   3. Multithreading during garbage collection
   4. Allocating memory in multiple regions simultaneously
4. Why might developers prefer manual GC configuration over ergonomics?
   1. Manual tuning is more cost-effective
   2. Ergonomics is not compatible with modern JVM versions
   3. Developers have better control over performance...
