Which of the following scenarios would dictate the use of a 64-bit processor instead of a 32-bit processor?
The correct answer is D. Implementation of more than 4GB of RAM. A 64-bit processor is required over a 32-bit processor when a system needs to utilize more than 4GB of RAM.

Why each option
A 64-bit processor is required over a 32-bit processor when a system needs to utilize more than 4GB of RAM.
Implementing access control lists (ACLs) is a software feature that does not dictate processor architecture for memory addressing.
The number of network cards does not inherently require a 64-bit processor; system bus capabilities and driver support are more relevant.
Implementing iSCSI attached storage is a storage protocol and does not specifically mandate a 64-bit processor over a 32-bit processor for its functionality.
32-bit processors are fundamentally limited to addressing 2^32 bytes of memory, which equates to 4GB. To access and utilize memory beyond this 4GB threshold, a system must employ a 64-bit processor and a 64-bit operating system, as 64-bit architectures can address vastly larger amounts of RAM.
