In a company, you need to add a new record for a recently hired employee into the employee database. Which command should you use to accomplish this task?
CREATE
SELECT
INSERT
UPDATE
Answer Description
To add a new record to a relational database, the INSERT command is used in SQL (Structured Query Language). This command allows you to insert new data into a table. The SELECT command is used to retrieve data, not to insert it. The CREATE command is used mainly to create new database objects like tables, not specific records. The UPDATE command is used to modify existing data within the database.

Creating a database involves defining a schema before any data can be stored within it.
True
False
Answer Description
The statement is correct because a schema must be defined for a database to structure the data, indicating how the data will be organized, which tables will be used, and the relationships between these tables. Without a schema, the database cannot efficiently organize or manage the data.

What device is necessary for establishing a connection between a home network and the Internet?
Modem
Switch
Repeater
Router
Hub
Answer Description
A modem connects a local network to the Internet by converting digital data from a computer to analog signals for transmission over telephone lines, cable systems, or satellite communications. Routers direct traffic on a network, switches connect devices within a network, hubs are basic networking devices that connect multiple devices, and repeaters regenerate signals to extend the reach of a network. However, only modems convert signals for Internet connectivity.

A mobile app for a library contains a 'Book' object with information about each book. If an app feature needs to display the title of a book, which aspect of the 'Book' object would the feature need to reference?
The feature would construct a new class to extract the title information.
The feature would invoke a method of the 'Book' object.
The feature would need to reference a property of the 'Book' object.
The feature would require a new variable outside the 'Book' object.
Answer Description
In object-oriented programming, a property is an attribute of an object that holds data. The title of the book would be stored in a 'title' property of the 'Book' object. Methods perform actions or computations, not store data. Classes define the structure of an object but are a blueprint, not individual data points. A variable is a storage location paired with an associated symbolic name (an identifier), which contains some known or unknown quantity of information referred to as a value; while a property can be accessed with variables, the property itself contains the information you want to retrieve, in this case, the title of the book.

Which query would efficiently retrieve the first name and last name of all employees in the 'Staff' table whose last name begins with the letter 'S' and are sorted in ascending order by their first name?
SELECT * FROM Staff WHERE LastName = 'S*';
SELECT FirstName, Surname FROM Staff WHERE Surname LIKE 'S%';
SELECT FirstName, LastName FROM Staff WHERE LastName LIKE 'S%' ORDER BY FirstName ASC;
SELECT FirstName, LastName FROM Staff WHERE LastName LIKE 'S%' ORDER BY FirstName DESC;
Answer Description
The correct answer is 'SELECT FirstName, LastName FROM Staff WHERE LastName LIKE 'S%' ORDER BY FirstName ASC;' because it includes all the necessary clauses for the specified conditions. It selects only the columns needed ('FirstName', 'LastName'), uses a WHERE clause with the LIKE operator to filter last names starting with 'S' (indicated by 'S%'), and sorts the results by 'FirstName' in ascending order. The other options are incorrect either due to missing the sorting condition ('ORDER BY'), incorrect sorting order, assuming a column that doesn't exist, or using incorrect wildcard character for selection.

In a professional office setting, you are responsible for ensuring the company's financial records are preserved against accidental loss. Which of the following backup strategies should you recommend to safeguard these critical files?
On-demand backups before major updates
Regular backups to cloud storage
Daily on-site backups only
Weekly backups to an external hard drive
Answer Description
Regular backups to cloud storage ensure that critical files are not only saved frequently but are also stored off-site, which protects against local disasters like fire, theft, or hardware failure. This approach adheres to the best practices for backing up essential data and provides a resilient recovery option. Daily on-site backups, while important, may not provide adequate protection against local disasters. Weekly backups might not give frequent enough data recovery points for critical financial records, leading to potential data loss. On-demand backups rely on manual intervention and may not occur with the necessary regularity for important documents.

What are the advantages of cloud storage for backups?
How often should backups be performed based on data criticality?
What are some best practices for implementing a backup strategy?
Why is it important to consider the location where backups are stored?
To comply with data storage laws that require all data to be stored off-site
To ensure data can be recovered even if the primary site is compromised
To reduce the cost of storage by using less expensive off-site facilities
To make data recovery faster by keeping it close to the primary data
Answer Description
The correct answer is 'To ensure data can be recovered even if the primary site is compromised'. Backing up data in a different physical location helps protect against natural disasters, theft, or other incidents that could occur at the primary site, which might render local backups useless if they are destroyed or unreachable along with the original data.

A new employee needs to connect their laptop to the conference room projector for a presentation. They are provided with a cable that has the same connector on both ends. What type of cable should they ensure they have in order to transmit both audio and video from the laptop to the projector?
DisplayPort cable
HDMI cable
VGA cable
RJ-45 cable
Answer Description
HDMI cables carry both audio and video signals between devices and have the same connector on both ends, which makes them the suitable choice for connecting a laptop to a projector for presentations that include sound and visual content. DisplayPort and VGA cables also carry video signals but DisplayPort cables can carry audio as well; however, they have a different connector than HDMI. RJ-45 is typically used for network connections and does not carry audio or video signals.

What should you consider when sharing documents with colleagues using a file-sharing service?
Share files via an open public link.
Email the documents directly from your personal account.
Upload files to a service that does not mention security features.
Use a service that encrypts files during transfer.
Answer Description
Using a service that encrypts files ensures that the data is protected during transfer and storage. This is important as unencrypted files could be easily intercepted or accessed by unauthorized users. Selecting a platform that emphasizes encryption helps safeguard sensitive information. Other options, such as public sharing or services that do not specify security measures, expose data to unnecessary risks.

Samantha is working at a graphic design company and needs to purchase a new computer. Her tasks involve heavy image processing and 3D rendering. When comparing two similar computer processors, why would she prefer a processor with a 3.2 GHz clock speed over one with a 2.5 GHz clock speed?
The 3.2 GHz processor can perform more cycles per second, which allows it to process tasks faster.
The 3.2 GHz processor has less thermal output, making the computer run cooler.
The 2.5 GHz processor will make the computer run more quietly.
The 2.5 GHz processor uses less energy, which makes it more environmentally friendly.
Answer Description
The clock speed of a processor is measured in GHz (gigahertz) and represents how many cycles per second the processor can perform. A higher clock speed means the processor can perform more cycles each second, leading to faster processing of tasks. For tasks that involve heavy processing like image editing and 3D rendering, a higher clock speed would generally result in better performance, therefore a 3.2 GHz processor would be preferred over the 2.5 GHz one.

Alice is working on a website that calculates the total cost of products selected by a user. She notices that she is repeatedly writing the same code to calculate the sum of prices. To make her code more efficient, she decides to group this repeated code in one place so that she can call it whenever she needs to perform the calculation. What is the programming concept Alice is utilizing to improve her code?
Variables
Objects
Arrays
Functions
Answer Description
Alice is using the concept of functions. Functions allow a programmer to create a reusable set of instructions. Instead of writing the same code over and over, a function can be defined once and called multiple times whenever the operation is needed. This enhances code readability and maintainability. The other options provided do not directly refer to grouping code for reusability; 'variables' store data values, 'arrays' hold multiple values in a single variable, and 'objects' encapsulate data and behavior but are not specifically for grouping and reusing a set of instructions.

You are performing a routine clean-up on your computer. Which of the following is the BEST method to remove unwanted software that ensures it is no longer taking up system resources?
Deleting the program's desktop shortcut
Using the operating system's uninstall feature
Defragmenting the hard drive
Rebooting the computer
Answer Description
Uninstalling a program using the system's built-in uninstall feature is the best option to remove unwanted software because it is designed to safely remove all components of the software from the system, without leaving behind residual files that could take up resources or cause conflicts. Rebooting the computer or deleting the program's desktop shortcut would not remove the actual software from the system. Defragmenting the hard drive could improve performance but would not remove any software.
