CompTIA FC0-U61 CompTIA IT Fundamentals+ Certification Exam Practice Test

Answer : C

A query language is a type of programming language that is used to manipulate and retrieve data from databases. A query language allows users to specify what data they want to access, filter, sort, join, or perform calculations on, without having to know how the data is stored or organized. A query language usually consists of keywords, operators, expressions, and clauses that form statements or commands. One of the most common and widely used query languages is SQL (Structured Query Language), which is supported by many relational database management systems (RDBMS).

A query language would most likely include tables and the select command, as these are essential components of working with databases. A table is a collection of data that is organized into rows and columns, where each row represents a record and each column represents a field or an attribute. A table can have a name, a schema (the definition of the columns and their data types), and constraints (the rules that enforce the integrity and validity of the data). For example, in the following SQL code, a table named Customers is created with four columns: CustomerID, Name, Email, and Phone:

Answer : B

When working with storage, different units of measurement are used to express the amount of data. The most common units are bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). Each unit is equal to 1,000 of the previous unit, except for bytes, which are the smallest unit. Therefore, 1,000,000MB can also be notated as 1,000GB or 1TB. The other options are incorrect because they are either too large or too small to represent 1,000,000MB. For example, 0.01PB is equal to 10,000GB or 10TB, which is much larger than 1,000,000MB. Similarly, 100GB is equal to 100,000MB or 0.1TB, which is much smaller than 1,000,000MB. And 10,000,000KB is equal to 10,000MB or 0.01TB, which is also much smaller than 1,000,000MB.Reference:

Answer : B

DSL stands for Digital Subscriber Line, which is a type of broadband internet service that uses copper telephone cabling. A network technician installing an RJ11 connector, which is the standard connector for telephone lines, is most likely using DSL as the network connection type. Fiber, satellite, and cable are other types of internet service, but they use different connectors and cables than RJ11.Reference:CompTIA IT Fundamentals+ (Exam FC0-U61) Module 4 / Unit 2 / Connecting to a Network, page 6;CompTIA Network+ N10-008 Certification Study Guide, Chapter 2: Network Devices and Cabling, page 55.

Answer : A

Boolean data types are data types that can only have one of two possible values: true or false. When evaluating Boolean expressions, such as logical operators (AND, OR, NOT) or comparison operators (=, <, >, etc.), the result is also a Boolean value. Therefore, there are only two possible results when evaluating Boolean data types: true or false.Reference:

Answer : A

A type 1 hypervisor OS, also known as a bare-metal hypervisor, is a software layer that runs directly on the hardware and allows multiple operating systems to run as virtual machines on the same host. This is the best choice for the test server because it provides the highest performance, isolation, and flexibility for testing different operating systems. A type 1 hypervisor OS can also support live migration, replication, and backup of virtual machines. A server OS is an operating system that is designed to run on a server, which is a computer that provides services to other computers on a network. A server OS may not support multiple operating systems or virtualization, and may have different hardware and software requirements than a test server. An embedded OS is an operating system that is embedded in a device, such as a smartphone, tablet, or smart TV. An embedded OS is usually optimized for a specific function and hardware, and may not support multiple operating systems or virtualization. A workstation OS is an operating system that is designed to run on a workstation, which is a high-end computer that is used for intensive tasks, such as graphics, video editing, or engineering. A workstation OS may support multiple operating systems or virtualization, but it may not have the same features and capabilities as a type 1 hypervisor OS, such as live migration, replication, and backup of virtual machines.Reference:

Answer : A

A web-based installation is a type of installation that uses a web browser to access and configure the settings of a device, such as a wireless router. A web-based installation typically requires the user to enter the IP address of the device in the browser's address bar, and then log in with a default username and password. The user can then modify the settings of the device according to their preferences and needs. A web-based installation is different from other types of installations, such as plug-and-play, driver-based, and server-based, which do not use a web browser to configure the device.Reference:How to Set Up a Wireless Router: A Step-By-Step Guide, step 3;CompTIA IT Fundamentals (ITF+) Certification Guide, page 98.

Answer : C

A VPN (Virtual Private Network) connection is a secure way of transmitting data over the internet by creating an encrypted tunnel between the sender and the receiver. This protects data in transit from being intercepted, modified, or stolen by unauthorized parties. VPNs can also mask the identity and location of the users, adding another layer of privacy and security. Backup tapes, encrypted flash drives, and FTP (File Transfer Protocol) are methods of storing or transferring data, but they do not protect data in transit as effectively as VPNs.Reference:
