NEW QUESTION # 21
(A company's database was hacked. A security officer conducted an audit and discovered that an attacker used a rainbow table to break into one of the user accounts to access the database. Which of the following is the best immediate response to this attack?)
Answer: D
Explanation:
The correct answer is D. Password hash salting. According to CompTIA DataSys+ objectives, rainbow table attacks specifically target hashed passwords by using precomputed hash values to quickly reverse weak or unsalted hashes back into their original plaintext passwords. If an attacker successfully used a rainbow table, it strongly indicates that the database stored password hashes without proper salting or used weak hashing algorithms.
Password salting is a defensive technique where a unique random value (the salt) is added to each password before hashing. This ensures that even if two users have the same password, their resulting hashes are different. More importantly, salting renders rainbow tables ineffective because the attacker would need to generate a separate rainbow table for every possible salt value, which is computationally impractical.
DataSys+ highlights salting as a critical immediate control to protect stored credentials once a password compromise is identified.
Option C, strong passwords, is a preventative control but not the best immediate response. Even strong passwords can be compromised if hashes are unsalted and exposed. Option A, security and awareness training, addresses user behavior but does not mitigate the technical weakness exploited in this attack. Option B, implementing security policies and procedures, is important for long-term governance but does not directly stop rainbow table attacks against existing password hashes.
CompTIA DataSys+ emphasizes that when credential storage mechanisms are compromised, administrators must prioritize cryptographic protections at the database level. This includes salting, using strong hashing algorithms, and forcing credential resets. Among the options provided, password hash salting is the most direct and effective response to prevent the same attack vector from succeeding again.
Therefore, the best immediate response is D. Password hash salting, making it the verified and correct answer aligned with CompTIA DataSys+ guidance.
NEW QUESTION # 22
Which of the following describes a scenario in which a database administrator would use a relational database rather than a non-relational database?
Answer: A
Explanation:
A scenario in which a database administrator would use a relational database rather than a non-relational database is when an organization wants to maintain consistency among the data in the database. A relational database is a type of database that organizes data into tables with predefined columns and rows, and enforces rules and constraints to ensure data integrity and accuracy. A relational database also supports transactions, which are sets of operations that must be executed as a whole or not at all, to prevent data corruption or inconsistency. The other options are either not exclusive to relational databases or not relevant to the choice of database type. For example, data encryption can be applied to both relational and non-relational databases, processing complex data sets may require specialized tools or techniques that are not dependent on the database type, and storing a large number of videos, photos, and documents may be better suited for a non-relational database that can handle unstructured or semi-structured data. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify and apply database structure types.
NEW QUESTION # 23
A server administrator wants to analyze a database server's disk throughput. Which of the following should the administrator measure?
Answer: A
Explanation:
The factor that the administrator should measure to analyze a database server's disk throughput is IOPS. IOPS, or Input/Output Operations Per Second, is a metric that measures the number of read and write operations that a disk can perform in one second. IOPS indicates the performance or speed of a disk and how well it can handle multiple requests or transactions. Higher IOPS means higher disk throughput and lower latency. IOPS can be affected by various factors, such as disk type, size, speed, cache, RAID level, etc. The other options are either not related or not sufficient for this purpose. For example, RPfvl is not a valid acronym or metric; latency is the time delay between a request and a response; reads are the number of read operations performed by a disk.
NEW QUESTION # 24
Which of the following statements contains an error?
Answer: C
Explanation:
The statement that contains an error is option B. This statement is missing the FROM clause, which specifies the table or tables from which to retrieve data. The FROM clause is a mandatory clause in a SELECT statement, unless the statement uses a subquery or a set operator. The correct syntax for option B would be:
SELECT EmpId FROM employee WHERE EmpId=90030 AND DeptId=34
Copy
The other options are either correct or valid SQL statements. For example, option A selects the employee ID from the employee table where the employee ID is equal to 90030; option C selects all columns from the employee table where the employee ID is equal to 90030; option D selects the employee ID from the employee table without any filter condition. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.

Which of the following should the manager use to best mitigate the situation?
