Explanation
Capacity planning is the process of determining the resources needed to meet the demand for a service or product. It involves estimating the number of staff members required to sustain the business in the case of a disruption, as well as other factors such as equipment, space, and budget Redundancy, geographic dispersion, and tabletop exercise are not directly related to determining the staff members needed for business continuity. Redundancy is the duplication of critical components or functions to increase reliability and availability . Geographic dispersion is the distribution of resources across different locations to reduce the impact of a localized disaster . Tabletop exercise is a simulation of a potential scenario that tests the effectiveness of a business continuity plan

Explanation
Mitigating controls are designed to reduce the impact or severity of an event that has occurred or is likely to occur. They do not prevent or detect the event, but rather limit the damage or consequences of it. For example, a backup system is a mitigating control that can help restore data after a loss or corruption.
In this case, the company is focused on reducing risks from removable media threats, which are threats that can compromise data security, introduce malware infections, or cause media failure123. Removable media threats can be used to bypass network defenses and target industrial/OT environments2. The company cannot prohibit removable media entirely because of certain primary applications that require them, so it implements mitigating controls to lessen the potential harm from these threats.
Some examples of mitigating controls for removable media threats are:
* Encrypting data on removable media
* Scanning removable media for malware before use
* Restricting access to removable media ports
* Implementing policies and procedures for removable media usage and disposal
* Educating users on the risks and best practices of removable media

Hybrid cloud since internal network and cloud computing is combined.
Private cloud = A cloud infrastructure setup and intended specifically for one client/customer.
Community Cloud = A cloud infrastructure shared by organizations within the same industry.
"Communitizes" the costs of cloud computing to reduce the cost burden per entity. Such as banking organizations going in together on a community cloud platform designed specifically for the banking industries cloud computing needs.
Hybrid = A mixed model where computing, storage, and applications are both on-premise and in the cloud, as well as utilizing more than one cloud service. Most organizations are a hybrid cloud.
Public = Any cloud service offered to the general public. Ranging from Google Drive, Microsoft Azure, Amazon Web Services, and Microsoft OneNote.

The scenario describes preventive controls, which are designed to stop malicious actors from gaining access to the organization's servers. This includes using multiple access points, such as a lobby, an access control vestibule, and multiple doors leading to the server floor, as well as caging the organization's hardware.
According to the CompTIA Security+ SY0-601 document, preventive controls are "designed to stop malicious actors from performing a malicious activity or gaining access to an asset." These controls can include technical solutions, such as authentication and access control systems, physical security solutions, such as locks and barriers, and administrative solutions such as policy enforcement.
