Explanation
The SA would do the other three regardless of the need to alter configurations. In this situation, the SA would have to present the change to the CCB in order to do the alteration.
There is no clarification on whether the change management process has been gone through. Any changes, regardless of how small or big, must go through the change management process. This allows proposals to be heard by end-users, management, and possibly stockholders. From there, it will be reviewed and either approved or denied, with reasons specified. From there, the administrator(s) can do whatever processes are necessary.
Change management is a process or procedure that defines the steps, roles, and responsibilities for implementing, documenting, and communicating any changes or updates to a system or service. Change management can help ensure that any changes or updates are done in a controlled and consistent manner, minimizing any risks or impacts to the system or service. Performing change management is the first thing that a systems administrator should do before altering the configuration of one of the finance department's database servers, as it can ensure that the change request is approved, authorized, tested, and verified before applying it to the database server.

Explanation
The best method to maintain data confidentiality after discovering that the servers have been compromised and sensitive files have been exfiltrated is encryption. Encryption is a process that transforms data into an unreadable format using an algorithm and a key. Encryption can protect data at rest, in transit, or in use from unauthorized access, tampering, or leakage. The systems administrator should encrypt the sensitive files and their backups using strong encryption algorithms and keys, and also encrypt the network traffic using protocols such as SSL or IPSec.

Explanation
User permissions are not correct is the most likely cause of the error 403 (Forbidden) that is returned when a coworker attempts to use a deployment script after being set up for API access to a public cloud environment by an administrator. API (Application Programming Interface) is a set of rules or specifications that defines how different software components or systems can communicate and interact with each other. API access is the ability to use or access an API to perform certain actions or tasks on a software component or system. User permissions are the settings or policies that control and restrict what users can do or access on a software component or system. User permissions can affect API access by determining what actions or tasks users can perform using an API on a software component or system. User permissions are not correct if they do not match or align with the intended or expected actions or tasks that users want to perform using an API on a software component or system. User permissions are not correct can cause error 403 (Forbidden), which means that the user does not have the necessary permission or authorization to perform the requested action or task using an API on a software component or system.

Explanation
The correct answer is B. Community cloud.
A community cloud is a cloud deployment model that involves a shared infrastructure among several organizations that have common interests, goals, or requirements. A community cloud can provide a high degree of security, privacy, and compliance, as well as cost savings and efficiency, for the participating organizations. A community cloud can be managed by one or more of the organizations, or by a third-party service provider .
A private cloud is a cloud deployment model that involves a dedicated infrastructure for a single organization.
A private cloud can provide a high degree of control, customization, and security for the organization, but it may also incur higher costs and complexity. A private cloud can be managed by the organization itself, or by a third-party service provider .
A hybrid cloud is a cloud deployment model that involves a combination of two or more different cloud models, such as private, public, or community clouds. A hybrid cloud can provide the benefits of both models, such as scalability, flexibility, and cost-effectiveness, as well as address the challenges of each model, such as security, compliance, and performance. A hybrid cloud can be managed by the organization itself, or by one or more service providers .
A public cloud is a cloud deployment model that involves a shared infrastructure for multiple organizations or individuals. A public cloud can provide a high degree of scalability, accessibility, and affordability for the users, but it may also pose some risks in terms of security, privacy, and compliance. A public cloud is managed by a third-party service provider .

Explanation
A content delivery network (CDN) is a distributed network of servers that delivers web content to users based on their geographic location, origin server, and content delivery server. A CDN can assist with the increased workload caused by sudden continuous bursts of traffic, as it can reduce the load on the origin server by caching and serving static content from edge servers closer to the users. A CDN can also improve the performance and availability of web content delivery, as it can reduce latency, bandwidth consumption, and network congestion.
