質問 2：
Which statement describes how garbage collection is used?
A. Garbage collection compresses the heap space through data compression.
B. Garbage collection frees memory by removing dead objects from the heap.
C. Garbage collection uses a properly tuned garbage collection agent to gather unused data in the heap and purge it from the system.
D. Garbage collection forces the freeing of memory in the heap by dumping the objects in the order of least used to most used.
正解：B

質問 7：
A customer is having performance problems and needs to understand how to resolve these performance issues. Their environment runs a single Java Virtual Machine (JVM).
How can clustering help with the performance issues?
A. Clustering creates multiple TCP/I P ports for a single JVM to allow for more connections to the application.
B. Clustering provides failover so that the failure of an overburdened application server can be met by a hot standby cluster member.
C. Clustering speeds garbage collection by having more garbage collectors to purge the application space.
D. Clustering provides a means to spread some of the workload across multiple heap spaces.
正解：B
