Tokenization involves the replacement of sensitive data fields with key or token values, which can ultimately be mapped back to the original, sensitive data values. Masking refers to the overall approach to covering sensitive data, and anonymization is a type of masking, where indirect identifiers are removed from a data set to prevent the mapping back of data to an individual. Encryption refers to the overall process of protecting data via key pairs and protecting confidentiality.

Explanation
Explanation:
The four possible approaches to risk are as follows: accept (do not patch and continue with the risk), avoid (implement solutions to prevent the risk from occurring), transfer (take out insurance), and mitigate (change configurations or patch to resolve the risk). Each of these answers contains at least one incorrect approach name.

Business continuity and disaster recovery (BCDR) solutions largely sit idle until they are actually needed. This traditionally has led to increased costs for an organization because physical hardware must be purchased and operational but is not used. By using a cloud system, an organization will only pay for systems when they are being used and only for the duration of use, thus eliminating the need for extra hardware and costs. Portability is the ability to easily move services among different cloud providers. Broad network access allows access to users and staff from anywhere and from different clients, and although this would be important for a BCDR situation, it is not the best answer in this case. On-demand self-service allows users to provision services automatically and when needed, and although this too would be important for BCDR situations, it is not the best answer because it does not address costs or the biggest benefits to an organization.

When leasing space in a data center versus utilizing cloud services, a customer has a much greater control over its systems and services, from both the hardware/software perspective and the operational management perspective. Costs, regulations, and security are all prime considerations regardless of the hosting type selected. Although regulations will be the same in either hosting solution, in most instances, costs and security will be greater factors with leased space.
