NEW QUESTION # 100
(Before installing a new database instance for an organization, a DBA needs to verify the amount of space, the hardware, and the network resources. Which of the following best describes this process?)
Answer: B
Explanation:
The correct answer is C. Checking for database prerequisites. According to CompTIA DataSys+ objectives, verifying prerequisites is a critical preparatory step before installing a new database instance.
Database prerequisites refer to the minimum and recommended requirements that must be met to ensure a successful installation and stable operation of the database system.
This process typically includes validating disk space availability, CPU capacity, memory (RAM), and network resources, as well as confirming operating system compatibility, required libraries, kernel parameters, and supporting services. DataSys+ emphasizes that failure to meet prerequisites can lead to installation errors, poor performance, instability, or security vulnerabilities after deployment. Therefore, DBAs are expected to thoroughly assess the environment before proceeding with installation.
Option A, performing patch management, refers to applying updates and fixes to existing systems to address bugs or security issues. This occurs after software is installed and operational, not before a new database instance is deployed. Option B, upgrading the database instance, involves moving from one version of a database to another and assumes an existing installation is already in place. Option D, provisioning the configuration, focuses on allocating and configuring resources (such as creating instances, users, or storage structures) after prerequisites have been validated.
CompTIA DataSys+ clearly separates environment validation from deployment and configuration activities. Checking prerequisites is a risk-reduction step that ensures the infrastructure can support the database workload and performance expectations from the start. It also supports capacity planning, compliance, and long-term maintainability.
Therefore, the process of verifying space, hardware, and network resources before installing a database instance is best described as checking for database prerequisites, making option C the correct and fully verified answer.
NEW QUESTION # 101
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: C
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.
NEW QUESTION # 102
Which of the following is a result of an on-path attack on a system?
Answer: B
Explanation:
A result of an on-path attack on a system is a Wi-Fi network that redirects to clones of legitimate websites. An on-path attack is a type of attack that intercepts and modifies the traffic between two parties without their knowledge or consent. An attacker can use an on-path attack to create a rogue Wi-Fi network that mimics a legitimate one, and then redirect the users to fake websites that look like the ones they intended to visit. The attacker can then steal the users' personal or financial information, such as usernames, passwords, credit card numbers, or bank account details. The other options are either results of different types of attacks or not related to attacks at all. For example, a website that has crashed and is no longer accessible may be a result of a denial-of-service attack, an email from an unknown source requesting bank account details may be a result of a phishing attack, and a web application that returns the addresses of its customers may be a result of a poor design or a data breach.
NEW QUESTION # 103
A database analyst notices a query statement is running slowly. Which of the following should the analyst review first?
Answer: D
Explanation:
Missing indexes are a common cause of slow queries, as indexes improve data retrieval speed by allowing efficient searching within tables.
NEW QUESTION # 104
Which of the following resources is the best way to lock rows in SQL Server?
Answer: C
Explanation:
The resource that is the best way to lock rows in SQL Server is RID. RID, or Row IDentifier, is an attribute that uniquely identifies each row in a heap table in SQL Server. A heap table is a table that does not have a clustered index, which means that the rows are not stored in any particular order. A RID consists of the file number, page number, and slot number of the row in the database. A RID can be used to lock rows in SQL Server to prevent concurrent access or modification by other transactions or users. A RID lock is a type of lock that locks a single row using its RID. A RID lock can be applied using the HOLDLOCK or XLOCK hints in a SELECT statement. The other options are either not related or not effective for this purpose. For example, TID, or Transaction IDentifier, is an attribute that uniquely identifies each transaction in a database; SID, or Security IDentifier, is an attribute that uniquely identifies each user or group in a Windows system; PID, or Process IDentifier, is an attribute that uniquely identifies each process in an operating system.
