Tech+ Part 5 Review

You have recently purchased a software package and need to install it on your company’s computer. Which of the following options is the BEST step to ensure that your software installation is authenticated and legally compliant?

• Keep the purchase receipt in a safe place as proof of authenticity.

• Record the serial number of your computer where the software will be installed.

• Ensure your computer’s time and date settings are accurate before installation.

• Enter a valid product key provided by the software vendor during installation.

Answer explanation

Explanation: Entering the product key during installation confirms that you have a legitimate copy of the software and activates it under the vendor’s license. Receipts or serial numbers don’t actually unlock or validate the software itself.

Real-World Scenario: It’s like buying a new video game online and then typing in the unique code you received by email when you install it—without that code, you can’t play, even if you have the receipt.

In a company’s inventory management system, a programmer needs to create a process that checks each item’s stock level and alerts the manager if the quantity is below 10. Which type of programming structure is most suitable for this task?

• Declaring a variable for each item

• Using a loop to iterate through all the items

• Creating a constant for the number 10

• Using a single if-else statement

Answer explanation

Explanation: A loop lets the program automatically go through every inventory item one after the other and apply the same check, so you don’t have to write repetitive code for each.

Real-World Scenario: Imagine you have a stack of 100 trading cards and you want to see which ones you have fewer than 10 of—you’d flip through each card one by one (a loop) instead of writing a separate instruction for card #1, #2, #3, and so on.

In a project management application, a “Task” object has been created to track work items. If you want to record the due date for a “Task,” which aspect of the “Task” object will you utilize?

• Task vector

• DueDate attribute

• DueDate array

• Task method

Answer explanation

Explanation: An attribute (or property) stores information about an object. The DueDate attribute holds the specific deadline for that task.

Real-World Scenario: It’s like when you add a homework assignment to your phone’s to-do list—the field where you type “Due: May 27” is the DueDate attribute.

Which action is most effective in confirming that a recently patched critical application has maintained full functionality?

• Conduct an end-to-end test of the application’s key workflows.

• Wait for users to report any issues they experience while using the application.

• Run a vulnerability scan on the application to ensure the patches were applied.

• Observe whether the application launches without errors.

Answer explanation

Explanation: End-to-end testing walks through every main feature just like a real user would, so you can catch any broken parts after the patch. Simply launching or scanning for vulnerabilities won’t guarantee that all workflows still work.

Real-World Scenario: After updating your favorite game, you play through the first level and test saving, loading, and multiplayer to make sure nothing got broken—this is like an end-to-end test.

An employee is attempting to upgrade the storage of an older workstation that requires more space for video editing tasks. The current drive is running out of space and is also relatively slow. Which type of hard drive would be the best upgrade to speed up file read and write processes and provide more storage capacity?

• A flash drive with USB 3.0 connectivity

• An external hard drive with a Thunderbolt connection

• A High RPM spinning disk hard drive with more storage

• A Solid State Drive (SSD) with higher storage capacity

Answer explanation

Explanation: SSDs use flash memory (no moving parts) to deliver much faster read/write speeds than any spinning disk, while still offering large capacity.

Real-World Scenario: It’s like swapping out a slow camera memory card for a high-speed SD card—photos and videos save almost instantly instead of taking forever.

In programming, an “if-else” statement is used to execute different blocks of code depending on certain conditions.

• True

• False

Answer explanation

Explanation: An if-else branches your code: if the condition is true, one block runs; otherwise (else) a different block runs.

Real-World Scenario: In a game, if your health drops to zero you see “Game Over”; else you keep playing. That decision-making is an if-else.

What is the BEST method for someone who has limited technical experience to perform data entry into a database?

• Using a graphical interface designed for data entry

• Constructing a data insertion query with a specialized builder tool

• Designing a customized code snippet to automate data insertion

Answer explanation

Explanation: A graphical UI presents simple forms to fill out, so non-technical users can enter data without writing any code or queries.

Real-World Scenario: Filling out a Google Form for a school project is much easier than typing SQL commands into a terminal.

What level of privacy can generally be expected when browsing websites on the Internet?

• Low expectation of privacy on public websites

• Complete privacy at all times

• Privacy guaranteed by all service providers

• Privacy only when using private browsing modes

Answer explanation

Explanation: Public sites often track you with cookies and server logs, so you should assume that most of your activity is visible to the site and third parties.

Real-World Scenario: When you post a comment on a forum, anyone can read it and see your username—there’s no guarantee of privacy.

Which file system supports large files and includes features such as encryption and permissions, and is commonly used in modern versions of Windows?

• HFS

• NTFS

• FAT32

• Ext4

Answer explanation

Explanation: NTFS (New Technology File System) is Windows’ default, handling very large files plus security features like encryption and permissions.

Real-World Scenario: Your Windows laptop’s hard drive is almost always formatted as NTFS so you can store big game or movie files and keep folders secure.

While working on a project that requires storing a list of daily temperatures in a program, you choose to use a data structure that holds multiple temperature values in a single variable. You need to be able to access these values by referring to an index number. Which data structure should you use?

• String

• Loop

• Dictionary

• Array

Answer explanation

Explanation: Arrays hold ordered items of the same type and let you pick any one by its index (position) number.

Real-World Scenario: Think of an ice cube tray with numbered slots. If you want the cube in slot 4, you just grab that one. An array works the same way for data.
