The attack that is being performed is brute-force. A brute-force attack is a type of attack that tries to guess a password or a key by systematically trying all possible combinations of characters or values until the correct one is found. A brute-force attack can use common passwords, such as “123456”, “password”, or “qwerty”, as well as dictionaries, word lists, or patterns to speed up the process. A brute-force attack can target a remote system, such as a web server, an email account, or a network device, and gain unauthorized access to its data or resources. The other options are either different types of attacks or not related to password guessing. For example, a DoS, or Denial-of-Service, attack is a type of attack that floods a system with requests or traffic to overwhelm its capacity and prevent legitimate users from accessing it; an SQL injection attack is a type of attack that inserts malicious SQL statements into an input field or parameter of a web application to manipulate or compromise the underlying database; a phishing attack is a type of attack that sends fraudulent emails or messages that appear to come from a trusted source to trick users into revealing their personalor financial information. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.4 Given a scenario, identify common types of attacks against databases.

The database administrator should mask the sensitive data before giving the developers access to the environment. Data masking is a technique that replaces sensitive data with fictitious but realistic data, such as random numbers or characters, to protect it from unauthorized access or exposure. Data masking preserves the format and structure of the original data, but does notreveal its actual value. This allows developers to work with realistic data without compromising its confidentiality or compliance. The other options are either insufficient or excessive for this scenario. For example, auditing access to tables with sensitive data may help monitor and track who accesses the data, but does not prevent it from being seen; removing sensitive data from tables may compromise the quality or completeness of the data, and may not be feasible if there is a large amount of data; encrypting connections to the development environment may protect the data in transit, but not at rest or in use. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.

The query that the administrator should use to create the table is option B. This query uses the CREATE TABLE statement to define a new table named XYZ with three columns: ID, Name, and Age. Each column has a data type and a constraint, such as NOT NULL, PRIMARY KEY, or CHECK. The other options either have syntax errors, use incorrect keywords, or do not specify the table name or columns correctly. References: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify and apply database structure types.
