NEW QUESTION # 118
A developer is designing a table that does not have repeated values. Which of the following indexes should the developer use to prevent duplicate values from being inserted?
Answer: A
Explanation:
The index that the developer should use to prevent duplicate values from being inserted is unique. A unique index is a type of index that enforces the uniqueness of the values in one or more columns of a table. A unique index ensures that no two rows in the table have the same value or combination of values in the indexed columns. A unique index helps to maintain data integrity and avoid data duplication or inconsistency. The other options are either not related or not effective for this purpose. For example, a single column index is a type of index that involves only one column of a table, but it does not prevent duplicate values unless it is also unique; an implicit index is a type of index that is automatically created by the database system when a constraint or a primary key is defined on a column or columns of a table, but it does not prevent duplicate values unless it is also unique; a composite index is a type of index that involves two or more columns of a table, but it does not prevent duplicate values unless it is also unique. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.
NEW QUESTION # 119
(Which of the following is a CPU-intensive operation that improves database performance and information retrieval?)
Answer: B
Explanation:
The correct answer is C. Index optimization. CompTIA DataSys+ identifies index management and optimization as a critical database maintenance activity that can be CPU-intensive but significantly improves query performance and information retrieval. Index optimization involves reorganizing, rebuilding, or analyzing database indexes to ensure they are structured efficiently and aligned with query usage patterns.
Indexes act as data access paths that allow the database engine to locate rows quickly without scanning entire tables. Over time, as data is inserted, updated, or deleted, indexes can become fragmented, inefficient, or poorly aligned with current workloads. Index optimization processes use CPU resources to analyze index statistics, rebalance tree structures, and rebuild index pages. While these operations temporarily consume CPU cycles, they result in faster query execution, reduced I/O operations, and improved overall system performance.
Option A, database compression, can reduce storage usage and I/O, but it primarily trades CPU for disk savings and does not directly optimize query access paths. Option B, patch management, involves applying software updates and security fixes and does not improve data retrieval performance. Option D, data corruption checks, are integrity and validation operations designed to detect or prevent data loss, not to enhance query performance.
CompTIA DataSys+ emphasizes that performance tuning often involves deliberate resource trade-offs. Index optimization is a prime example: it consumes CPU during maintenance windows to deliver long-term performance benefits during normal database operations. Well-optimized indexes reduce query latency, improve response times, and enhance user experience, especially in read-heavy or reporting environments.
DataSys+ also highlights best practices such as scheduling index maintenance during low-usage periods and monitoring CPU impact to avoid service disruptions. When implemented correctly, index optimization is one of the most effective ways to improve database performance and information retrieval.
Therefore, the CPU-intensive operation that improves database performance and information retrieval is index optimization, making option C the correct and fully verified answer.
NEW QUESTION # 120
Which of the following qualifiers removes duplicate records from a SQL SELECT statement when included in a query?
Answer: C
NEW QUESTION # 121
A database administrator would like to create a table named XYZ. Which of the following queries should the database administrator use to create the table?
Answer: D
Explanation:
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.
NEW QUESTION # 122
An automated script is using common passwords to gain access to a remote system. Which of the following attacks is being performed?
Answer: C
Explanation:
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 personal or financial information.
