WGU Introduction to IT Sample Questions (Q112-Q117):

NEW QUESTION # 112
Which type of services are Google Apps, Dropbox, and GoToMeeting?

Answer: C

Explanation:
Google Apps, Dropbox, and GoToMeeting are all examples of Software-as-a-Service (SaaS). SaaS is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the internet. This contrasts with IaaS, which provides virtualized computing resources over the internet, and PaaS, which offers hardware and software tools over the internet.
1.Google Apps (now Google Workspace) provides productivity and collaboration tools.
2.Dropbox offers cloud storage and file synchronization services.
3.GoToMeeting is an online meeting, desktop sharing, and video conferencing software.
All three services are accessed over the internet and do not require users to manage hardware or software updates, which is characteristic of the SaaS model.
References: The information is verified by multiple sources that discuss cloud service models, including articles that specifically categorize Google Workspace, Dropbox, and GoToMeeting as SaaS12. Additionally, Google's support documentation for GoToMeeting integration with Google Workspace further supports this classification3.


NEW QUESTION # 113
What type of a system requirement involves preventing unauthorized access to data?

Answer: B

Explanation:
*Unauthorized access refers to gaining entry or access to a system, physical or electronic, without the permission of the owner or administrator.
*Security is the type of system requirement that involves preventing unauthorized access to data.
*Security measures include:
oAuthentication: Verifying user identity.
oEncryption: Protecting data from unauthorized viewing.
oAccess controls: Limiting who can access specific resources.
oFirewalls: Filtering network traffic.
*Ensuring security helps safeguard sensitive information and maintain data integrity.

NEW QUESTION # 114
What is a characteristic of cloud computing?

Answer: A

Explanation:
1.On-demand self-service:
oCloud computing services do not require human administrators. Users can provision, monitor, and manage computing resources as needed.
oWith data centers worldwide, cloud providers have vast compute and storage assets ready for use.
oDevelopers can select resources and tools through a self-service portal, building applications without waiting for physical servers.
oAdmins set policies, but within those guardrails, employees have the freedom to build, test, and deploy apps.

*Businesses are beginning to use big data to integrate vast amounts of electronic data into analysis in order to gain insight for better decision making.
*Explanation: Big data allows organizations to analyze large datasets to uncover patterns, trends, and correlations, leading to more informed decisions and strategic business moves1.
* Therefore, the correct answer is A. To integrate vast amounts of electronic data into analysis in order to gain insight for better decision making.


NEW QUESTION # 116
What is the role of the compiler?

Answer: D

Explanation:
1.Lexical Analysis:
oThe source code is first tested by the compiler's lexer, which breaks it down into tokens (such as keywords, identifiers, operators, and punctuation).
oThis step identifies the individual elements of the program.
2.Syntactic and Semantic Analysis:
oThe compiler performs syntactic analysis, checking the source code for syntax errors and ensuring it follows the correct language-specific rules.
oIf any errors occur, the compiler throws an error and stops the compilation.
oAdditionally, the compiler performs semantic analysis to find the meaning of the code.
oIt checks for logical errors, such as type mismatches, undeclared variables, and incorrect usage of operators.
3.Optimization:
oOnce the code is syntactically correct, the compiler performs low-level optimization to improve performance.
oThis may involve reducing memory usage or optimizing code for speed by rearranging instructions or eliminating unnecessary operations.
4.Output Code Generation:
oFinally, the compiler generates machine code corresponding to the original source code.
oThe resulting machine code resides in a binary file that the computer's hardware can execute directly.
Why Do We Use Compilers?
*Compilers catch syntax and semantic errors before running the code, saving time and preventing crashes.
*They optimize code for efficient execution, resulting in faster, more compact programs.
Disadvantages of a Compiler:
*Compiled code is platform-dependent, meaning it produces a machine-specific executable file.
*Code compiled on one type of machine won't run on another type without recompilation1.
