Question: 1 / 510

Semaphores can be used to limit what in a resource pool?

The size of the pool

The number of resources being used at the same time

Semaphores are synchronization tools that can be used to restrict the number of concurrent threads that can access a resource pool. They are mainly used to control access to a finite set of resources such as database connections, file handles, or network connections. Option A is incorrect because semaphores do not affect the size of the pool itself, but rather the number of resources that can be used at one time. Option C is incorrect because semaphores do not control the type of resources in a pool, but rather the access to those resources. Option D is incorrect because semaphores do not have any impact on the lifetime of resources in a pool.
