CompTIA ITF+ Applications and Software Questions and Answers

Question 1

A small startup is developing a new mobile application. They need a cloud computing service model that allows them to build, test, and deploy their application without managing the underlying infrastructure such as servers, storage, and networking. Which of the following models BEST fits their needs?

Accepted Answer

Platform as a Service (PaaS)

Answer

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. IaaS would require them to manage the operating systems and middleware, while SaaS provides ready-to-use software, not a development platform. DaaS is focused on providing virtual desktops.

Question 2

A company purchases a software license that allows them to install a program on up to 50 computers within their organization, but only 10 users can actively run the software at the exact same time. What type of software license does this scenario describe?

Accepted Answer

Concurrent License

Answer

A concurrent license limits the number of users who can access the software simultaneously. Even though it might be installed on many machines, the license server only allows a specific number of active connections at once. A single-use license is for one user, open-source has different terms related to code access, and a perpetual license refers to the duration of the license, not the simultaneous usage.

Question 3

Which of the following is an example of application software, as opposed to system software?

Accepted Answer

Web Browser

Answer

A web browser is application software because it is designed for an end-user to perform a specific task—in this case, accessing the internet. Device drivers, firmware, and operating systems are all examples of system software, which manage the computer's hardware and provide a platform for applications to run.

Question 4

In a common three-tier application architecture model, which layer is responsible for interacting with the user and displaying information?

Accepted Answer

Presentation Layer

Answer

The Presentation Layer is the user interface (UI) of the application. It's what the end-user sees and interacts with, and it is responsible for displaying data and receiving user input. The Business Logic Layer handles processing and rules, while the Data Layer manages storage and retrieval of data.

Question 5

A user wants to install a new piece of software. Which of the following is considered a best practice to perform BEFORE starting the installation process?

Accepted Answer

Read the End-User License Agreement (EULA).

Answer

Reading the End-User License Agreement (EULA) is a crucial best practice before installation. It outlines the user's rights and restrictions regarding the software. The other options are poor security practices or relate to post-installation cleanup.
