A. B. C. D.Correct Answer: C.
Option A is incorrect.
The disks could only be attached to a computer in the same Zone.
Hence, this is an invalid option.
Option B is incorrect.
The disks could only be attached to a computer in the same Zone.
Hence, this is an invalid option.
Option C is correct.
Attaching a disk in one region to a computer in a different region is not allowed by Google.
Option D is incorrect.
Refer to the explanations above for option A and option.

Attaching a disk in one region to a computer in a different region is a process known as cross-region disk attachment. This process can be done on Google Cloud Platform (GCP) to enable a virtual machine (VM) in one region to access a persistent disk located in another region. The correct statement regarding attaching a disk as described above is option A, "Attaching a disk in one region to a computer in a different region can be done to reduce latency."
Latency refers to the delay that occurs when data is transmitted over a network. In a cloud environment, where data is stored in different regions, the distance between the computer and the disk can result in high latency. By attaching a disk in one region to a computer in a different region, data access can be optimized to reduce latency. This is because data can be read and written from the disk located in the same region as the virtual machine, which can result in faster data transfer and improved performance.
Option B, "Attaching a disk in one region to a computer in a different region can be done to implement BCM," is incorrect. BCM stands for Business Continuity Management, which is the process of ensuring that essential business functions can continue in the event of a disruption. Cross-region disk attachment is not related to implementing BCM.
Option C, "Attaching a disk in one region to a computer in a different region is not allowed by Google," is also incorrect. Google Cloud Platform allows for cross-region disk attachment, which can be configured through the GCP Console, API, or command-line tools.
Therefore, the correct answer is option A, "Attaching a disk in one region to a computer in a different region can be done to reduce latency."
