질문 # 49
A database administrator needs to ensure continuous availability of a database in case the server fails. Which of the following should the administrator implement to ensure high availability of the database?
정답：C
설명：
The option that the administrator should implement to ensure high availability of the database is replication. Replication is a process that copies and synchronizes data from one database server (the primary or source) to one or more database servers (the secondary or target). Replication helps ensure high availability of the database by providing redundancy, fault tolerance, and load balancing. If the primary server fails, the secondary server can take over and continue to serve the data without interruption or data loss. The other options are either not related or not suitable for this purpose. For example, ETL is a process that extracts, transforms, and loads data from one source to another for analysis or reporting purposes; database dumping is a process that exports the entire content of a database to a file for backup or migration purposes; backup and restore is a process that copies and recovers data from a backup device or media in case of a disaster or corruption. Reference: CompTIA DataSys+ Course Outline, Domain 5.0 Business Continuity, Objective 5.3 Given a scenario, implement replication of database management systems.

Which of the following is used to document the system catalog in a database?
정답：A
설명：
A data dictionary documents the system catalog by providing metadata about database objects, their structure, and relationships within the database.
질문 # 51
(A database administrator realizes that certain data was not captured correctly when it was imported. Which of the following commands should the administrator use to fix the issue?)
정답：C
설명：
The correct answer is A. UPDATE. CompTIA DataSys+ classifies the UPDATE command as a Data Manipulation Language (DML) statement used to modify existing data within a table. When data is imported incorrectly-such as having wrong values, missing fields, or improperly formatted entries-the appropriate corrective action is to update the affected records rather than removing data structures or deleting records outright.
The UPDATE command allows a database administrator to correct specific columns or rows by setting them to the proper values while preserving the rest of the dataset. This aligns with DataSys+ best practices, which emphasize data integrity, minimal disruption, and precision when fixing data-related issues. By using a WHERE clause, the administrator can target only the incorrect records, reducing risk and avoiding unnecessary data loss.
Option B, DROP TABLE, is a DDL command that completely removes a table and all its data and structure.
This is an extreme action and would not be appropriate when only certain data values are incorrect. Option C, DELETE, removes rows from a table, which may result in loss of valid data rather than correcting it. Deletion is only appropriate when data should no longer exist, not when it needs correction. Option D, ALTER TABLE, is also a DDL command used to modify table structure (such as adding or changing columns), not to fix incorrect row-level data.
CompTIA DataSys+ stresses the importance of choosing the least destructive and most targeted command when resolving data issues. Correcting imported data typically involves adjusting values rather than altering schema or removing data entirely.
Therefore, to fix incorrectly captured imported data while maintaining database integrity and availability, the administrator should use the UPDATE command, making option A the correct and fully verified answer.
질문 # 52
A DBA is reviewing the following logs to determine the current data backup plan for a primary data server:
Which of the following best describes this backup plan?
정답：C
설명：
The backup plan that best describes the logs is weekly full, daily incremental. This means that a full backup of the entire database is performed once a week, and then only the changes made since the last backup are backed up every day. This can be inferred from the logs by looking at the size and duration of the backups. The full backups are larger and take longer than the incremental backups, and they occur every seven days. The other backup plans do not match the pattern of the logs.
질문 # 53
A database administrator is assisting developers with finding the best tables and columns to include in an application. Which of the following resources is the most relevant for this task?
정답：B
설명：
A data dictionary provides detailed information about database tables, columns, and their attributes, helping developers understand the structure and relationships to select the best tables and columns for the application.
