CompTIA DataSys+ Certification Exam Sample Questions (Q63-Q68):

NEW QUESTION # 63
Which of the following services is responsible for assigning, managing, and reclaiming IP addresses on a TCP
/IP-based network?

Answer: B

Explanation:
The service that is responsible for assigning, managing, and reclaiming IP addresses on a TCP/IP-based network is DHCP. DHCP, or Dynamic Host Configuration Protocol, is a service that automatically assigns IP addresses and other network configuration parameters, such as subnet mask, default gateway, DNS server, etc., to computers or devices on a network. DHCP helps simplify the administration and management of IP addresses on a network, as well as avoid conflicts or errors caused by manual or duplicate assignments.
DHCP also allows computers or devices to release or renew their IP addresses when they join or leave the network. The other options are either different services or not related to IP addresses at all. For example, DNS, or Domain Name System, is a service that translates domain names into IP addresses and vice versa; LDAP, or Lightweight Directory Access Protocol, is a service that provides access to directory information such as users, groups, or devices on a network; ISMTP is not a valid acronym or service. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.1 Given a scenario, select an appropriate database deployment method.


NEW QUESTION # 64
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?

Answer: C

Explanation:
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.


NEW QUESTION # 65
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?

Answer: C

Explanation:
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.


NEW QUESTION # 66
Which of the following scripts would set the database recovery model for sys.database?

Answer: D

Explanation:
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. Reference: CompTIA DataSys+ Course Outline, Domain 3.0 Database Management and Maintenance, Objective 3.1 Given a scenario, perform common database maintenance tasks.


NEW QUESTION # 67
Which of the following NoSQL database types best categorizes MongoDB?

Answer: D

Explanation:
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. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify common database types.
