問題 #58
A database administrator is new to a company and wants to create a document that illustrates the interaction between tables. Which of the following should the administrator create?

A. Data dictionary
B. Database reference manual
C. Troubleshooting guide
D. Entity relationship diagram

答案：D

解題說明：
The document that the administrator should create to illustrate the interaction between tables is an entity relationship diagram. An entity relationship diagram (ERD) is a graphical representation of the entities (tables), attributes (columns), and relationships (constraints) in a database. An ERD helps the administrator to visualize the structure and design of the database, as well as the dependencies and associations among the tables. The other options are either different types of documents or not related to the interaction between tables. For example, a troubleshooting guide is a document that provides instructions on how to solve common problems or errors in a database; a data dictionary is a document that describes the metadata (information about data) of a database; a database reference manual is a document that provides information on how to use or operate a database. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.

問題 #59
Which of the following describes the purpose of a snapshot?

A. To create an image of a database
B. To create a dynamic data replication
C. To create a
D. To create a synonym

答案：A

解題說明：
The purpose of a snapshot is to create an image of a database. A snapshot is a copy of the state and content of a database at a specific point in time. A snapshot can be used for various purposes, such as backup and recovery, testing and development, reporting and analysis, etc. A snapshot can be created using various techniques, such as full copy, incremental copy, differential copy, etc. A snapshot can also be created using various tools or commands provided by the database system or software. The other options are either incorrect or irrelevant for this question. For example, dynamic data replication is a process that copies and synchronizes data from one database server (the source) to one or more database servers (the target) in real time; a synonym is an alias or an alternative name for an object in a database; C is an incomplete option. References: CompTIA DataSys+ Course Outline, Domain 5.0 Business Continuity, Objective 5.2 Given a scenario, implement backup and restoration of database management systems.

問題 #60
Which of the following are ORM tools? (Choose two.)

A. PLSQL
B. PHP
C. T-SQL
D. Entity Framework
E. XML
F. Hibernate

答案：D,F

問題 #61
Which of the following NoSQL database types best categorizes MongoDB?

A. Key-value stores
B. Graph
C. Document
D. Column-oriented

答案：C

解題說明：
The NoSQL database type that best categorizes MongoDB is document. Document databases are databases that store and manage data as documents, which are collections of fields and values in formats such as JSON (JavaScript Object Notation) or XML (Extensible Markup Language). Document databases do not use any schema or structure to organize data, but rather use identifiers or indexes to enable flexible and dynamic access to data based on fields or values.
Document databases are suitable for storing large amounts of complex or unstructured data that have variable attributes or nested structures. MongoDB is an example of a document database that uses JSON-like documents to store and query data. The other options are either different types of NoSQL databases or not related to NoSQL databases at all. For example, column- oriented databases are databases that store and manage data as columns rather than rows; graph databases are databases that store and manage data as nodes and edges that represent entities and relationships; key-value stores are databases that store and manage data as pairs of keys and values.

問題 #62
Over the weekend, a company's transaction database was moved to an upgraded server. All validations performed after the migration indicated that the database was functioning as expected. However, on Monday morning, multiple users reported that the corporate reporting application was not working.
Which of the following are the most likely causes? (Choose two.)

A. The reporting application cannot keep up with the new, faster response from the database.
B. The reporting jobs that could not process during the database migration have locked the application.
C. The reporting application's mapping to the database location was not updated.
D. The access permissions for the service account used by the reporting application were not changed.
E. The new database server has its own reporting system, so the old one is not needed.
F. The database server is not permitted to fulfill requests from a reporting application.

答案：C,D

解題說明：
The most likely causes of the reporting application not working are that the access permissions for the service account used by the reporting application were not changed, and that the reporting application's mapping to the database location was not updated. These two factors could prevent the reporting application from accessing the new database server. The other options are either irrelevant or unlikely to cause the problem. Reference: CompTIA DataSys+ Course Outline, Domain 3.0 Database Management and Maintenance, Objective 3.2 Given a scenario, troubleshoot common database issues.
