Final answer:
The correct answer is option c, which corresponds to the RPO (Recovery Point Objective) of 12 hours, indicating the company's tolerance for data loss.
Step-by-step explanation:
The correct answer is option c. RPO = 12. RPO stands for Recovery Point Objective, which is the maximum tolerable period in which data might be lost from an IT service due to a major incident. If a company is comfortable with losing 12 hours worth of newly entered data, it means that the company can afford to lose data that has been entered in the last 12 hours before a disaster occurs without significant harm to the business. In this case, they have an RPO of 12 hours. RTO, or Recovery Time Objective, relates to the maximum tolerable length of time that a service level can be down after a disaster and is not the correct term in this context. The fact that data backups are done on tape each evening is related to the method of backing up data but does not directly answer the question regarding the amount of data loss a company is willing to tolerate.
Data backup being done on a tape each evening (option d) implies the data is being backed up, but it does not specify the time period beyond each evening. Options a and b are not applicable as they represent Recovery Time Objective (RTO) rather than Recovery Point Objective (RPO).
