CompTIA DataSys+ Certification Exam 認定 DS0-001 試験問題 (Q106-Q111):質問 # 106
Which of the following have data manipulation and procedural scripting power? (Choose two.)
  • A. PQL
  • B. T-SQL
  • C. Advanced
  • D. SQL
  • E. PL/SQL
  • F. SQL
正解：B、E
解説：
The two options that have data manipulation and procedural scripting power are PL/SQL and T-SQL. PL/SQL, or Procedural Language/Structured Query Language, is an extension of SQL that adds procedural features to SQL for Oracle databases. PL/SQL allows users to create and execute stored procedures, functions, triggers, packages, etc., using variables, loops, conditions, exceptions, etc., in addition to SQL commands. PL/SQL helps improve the performance, functionality, modularity, and security of SQL queries and applications. T-SQL, or Transact-SQL, is an extension of SQL that adds procedural features to SQL for Microsoft SQL Server databases. T-SQL allows users to create and execute stored procedures, functions, triggers, etc., using variables, loops, conditions, exceptions, etc., in addition to SQL commands. T-SQL helps improve the performance, functionality, modularity, and security of SQL queries and applications. The other options are either not related or not having both data manipulation and procedural scripting power. For example, PQL, or Power Query Language, is a data analysis and transformation language for Microsoft Power BI and Excel; Advanced SQL is a term that refers to the advanced features or techniques of SQL, such as subqueries, joins, aggregations, etc.; SQL, or Structured Query Language, is a standard language for manipulating and querying data in relational databases, but it does not have procedural features. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.

質問 # 107
Which of the following scripts would set the database recovery model for sys.database?
  • A.
  • B.
  • C.
  • D.
正解：A
解説：
The script that would set the database recovery model for sys.database is option A. This script uses the ALTER DATABASE statement to modify the recovery model of the sys.database to full with no wait. The other options either have syntax errors, use incorrect keywords, or do not specify the recovery model correctly.

質問 # 108
Which of the following is used to write SQL queries in various programming languages?
  • A. Excel
  • B. Object-relational mapping
  • C. Indexing
  • D. Normalization
正解：B
解説：
The option that is used to write SQL queries in various programming languages is object- relational mapping. Object-relational mapping (ORM) is a technique that maps objects in an object-oriented programming language (such as Java, Python, C#, etc.) to tables in a relational database (such as Oracle, MySQL, SQL Server, etc.). ORM allows users to write SQL queries in their preferred programming language without having to deal with the differences or complexities between the two paradigms. ORM also provides users with various benefits such as code reuse, abstraction, validation, etc. The other options are either not related or not effective for this purpose. For example, indexing is a technique that creates data structures that store the values of one or more columns of a table in a sorted order to speed up queries; Excel is a software application that allows users to organize and manipulate data in rows and columns; normalization is a process that organizes data into tables and columns to reduce redundancy and improve consistency.

質問 # 109
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?
  • A. Composite
  • B. Implicit
  • C. Single column
  • D. Unique
正解：D
解説：
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.

質問 # 110
Which of the following cloud delivery models provides users with the highest level of flexibility regarding resource provisioning and administration?
  • A. SaaS
  • B. PaaS
  • C. DBaaS
  • D. IaaS
正解：D
解説：
The cloud delivery model that provides users with the highest level of flexibility regarding resource provisioning and administration is IaaS. IaaS, or Infrastructure as a Service, is a cloud delivery model that provides users with access to virtualized computing resources, such as servers, storage, network, and operating systems, over the internet. Users can provision, configure, and manage these resources according to their needs and preferences, without having to worry about the maintenance or security of the physical infrastructure. IaaS offers users the most control and customization over their cloud environment, as well as the ability to scale up or down as needed. The other options are either different cloud delivery models or not related to cloud computing at all. For example, DBaaS, or Database as a Service, is a cloud delivery model that provides users with access to database management systems and tools over the internet; SaaS, or Software as a Service, is a cloud delivery model that provides users with access to software applications and services over the internet; PaaS, or Platform as a Service, is a cloud delivery model that provides users with access to development platforms and tools over the internet. Reference: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.1 Given a scenario, select an appropriate database deployment method.
