NEW QUESTION # 118
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: C
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.
NEW QUESTION # 119
A company needs to prepare a document that establishes the responsibilities, metrics, penalties, and other generalities that a provider would have to fulfill for customers to use its platforms.
Which of the following documents meets these requirements?
Answer: D
Explanation:
The document that meets these requirements is an SLA. An SLA, or Service Level Agreement, is a contract between a service provider and a customer that defines the scope, quality, and terms of the service delivery. An SLA typically includes the responsibilities, metrics, penalties, and other generalities that a provider would have to fulfill for customers to use its platforms. An SLA also establishes the expectations and obligations of both parties, as well as the methods for measuring and monitoring the service performance. The other options are either different types of documents or not related to service delivery. For example, a DOU, or Data Use Agreement, is a document that governs the sharing and use of data between parties; an MOU, or Memorandum of Understanding, is a document that expresses a mutual agreement or intention between parties; a SOW, or Statement of Work, is a document that describes the specific tasks and deliverables of a project or contract. Reference: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.4 Given a scenario, implement service level agreements.
NEW QUESTION # 120
A company needs information about the performance of users in the sales department. Which of the following commands should a database administrator use for this task?
Answer: C
Explanation:
The command that the database administrator should use for this task is SELECT. The SELECT command is a SQL statement that retrieves data from one or more tables or views in a database. The SELECT command can also use various clauses or options to filter, group, sort, or aggregate data according to specific criteria or conditions. By using the SELECT command, the database administrator can obtain information about the performance of users in the sales department, such as their sales volume, revenue, commission, etc. The other options are either not related or not suitable for this task. For example, DROP is a SQL command that deletes an existing table or object from a database; UPDATE is a SQL command that modifies existing data in one or more rows of a table; DELETE is a SQL command that removes existing data from one or more rows of a table. 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 # 121
Which of the following does a database administrator need to know before planning the setup of a new server for a client?
Answer: B
Explanation:
Knowing the size and importance of the server is crucial for proper planning, as it determines the required resources, configurations, and level of redundancy needed to meet the client's needs.
NEW QUESTION # 122
A database administrator needs a tool to document and explain the relationships between data in an organization's database. Which of the following is the best tool to accomplish this task?
Answer: B
Explanation:
The best tool for the database administrator to document and explain the relationships between data in an organization's database is a UML editor. A UML editor is a software application that allows users to create, edit, and visualize diagrams using the Unified Modeling Language (UML). UML is a standard language for modeling software systems and their components, such as classes, objects, relationships, behaviors, etc. UML can also be used to document and explain the relationships between data in an organization's database by creating entity relationship diagrams (ERDs), which are graphical representations of the entities (tables), attributes (columns), and relationships (constraints) in a database. A UML editor can help the administrator to document and explain the relationships between data by providing features such as drag-and-drop, templates, symbols, validation, etc. The other options are either not suitable or not optimal for this task. For example, a text editor is a software application that allows users to create and edit plain text files; a word processor is a software application that allows users to create and edit text documents; an SQL query is a statement that performs an operation on a database using Structured Query Language (SQL). Reference: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.
