A differential backup is a type of backup that copies all the files that have changed since the last full backup. A differential backup requires more storage space than an incremental backup, which only copies the files that have changed since the last backup of any type, but it also requires less time to restore in case of data loss. By combining a full, weekly backup with daily differential backups, the administrator can ensure that only two backup sets are needed to restore a full backup as quickly as possible.

A database server is a server that hosts a database management system (DBMS) that stores, organizes, and manipulates data. A database server is suitable for housing customer sales records, as it can provide fast and secure access, query and analysis capabilities, backup and recovery options, and scalability and performance optimization. Some examples of database servers are Microsoft SQL Server, Oracle Database, MySQL, and PostgreSQL. Verified References: [What is a Database Server?]

Password length is the first password policy that the administrator should implement to help mitigate the chance of a successful brute-force attack. A brute-force attack is a method of guessing passwords by trying all possible combinations of characters until the correct one is found. The longer the password, the more combinations there are, and the more time and resources it takes to crack it. Therefore, password length is a key factor in password strength and security.

Wiping the drives is the most appropriate step to recycle and reuse the system drives. Wiping the drives means erasing all the data on the drives and overwriting them with random or meaningless data. This can help prevent data leakage, comply with regulations, and prepare the drives for a new installation or configuration. Wiping the drives is different from deleting or formatting the drives, which only remove the references to the data but not the data itself. References: (Objective 1.3)
