Using two different cloud solutions to store data is an example of platform diversity, which helps reduce dependency on a single cloud provider and enhances resilience against vendor-specific failures or outages.
Load balancing (A) distributes workloads across resources; parallel processing (B) refers to simultaneous processing of tasks; clustering (D) involves grouping servers to act as a single system.
Platform diversity is a recognized architectural strategy to improve availability and fault tolerance, covered in Security Architecture concepts for SY0-701#6:Chapter 10 CompTIA Security+ Study Guide#

The IT manager is creating a Business Continuity Plan (BCP). A BCP describes how an organization will continue to operate during and after a disaster or global incident. It ensures that critical business functions remain operational despite adverse conditions, with a focus on minimizing downtime and maintaining essential services.
* Physical security relates to protecting physical assets.
* Change management ensures changes in IT systems are introduced smoothly, without disrupting operations.
* Disaster recovery is a subset of business continuity but focuses specifically on recovering from IT- related incidents.

Tokenization is a process that replaces sensitive data, such as credit card information, with a non-sensitive equivalent (token) that can be used in place of the actual data. This technique is particularly useful in securely storing payment information because the token can be safely stored and transmitted without exposing the original credit card number.
