Explanation
RAID 1 is a type of RAID level that creates an exact copy or mirror of data on two or more disks. RAID 1 can provide redundancy and fault tolerance, as it can survive the failure of one disk without losing any data. RAID
1 can also improve read performance, as it can access data from multiple disks simultaneously. The administrator should configure RAID 1 to set up mirroring on a storage array. References: CompTIA Cloud+ Certification Exam Objectives, page 9, section 1.4

User quotas are a feature that allows the administrator to limit the amount of storage space that a user or a group of users can consume on a file server. User quotas can help to control storage usage by preventing users from storing excessive or unnecessary files, as well as by enforcing fair and consistent storage policies across the organization. User quotas can also help to monitor and report on the storage consumption and trends of the users, and alert the administrator or the users when they are approaching or exceeding their quota limits.

Explanation
Simple Network Management Protocol (SNMP) is a protocol that enables monitoring and managing network devices and components in an IP network. SNMP can help monitor all computer, storage, and network components of a private cloud environment, as it can collect and report information about their status, performance, configuration, and events. SNMP can also help troubleshoot and optimize the private cloud environment, as it can detect and alert any issues or anomalies related to the network devices and components.

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.
