Exam Questions and Answers
1: What is the primary purpose of the CompTIA Security+
certification?--- correct precise answer ---
The primary purpose of the CompTIA Security+ certification is to
validate foundational skills and knowledge in IT security, focusing
on risk management, threat assessment, and the implementation of
security measures to protect systems and data.

,Page 2 of 19
The six domains covered in the CompTIA Security+ (SY0-701) exam
are:1. Threats, Attacks, and Vulnerabilities2. Architecture and
Design3.
Implementation4. Operations and Incident Response5. Governance,
Risk, and Compliance6. Security Concepts and Technologies
3: What is the CIA triad in information security?--- correct precise
answer ---
The CIA triad in information security stands for Confidentiality,
Integrity, and Availability. It is a model designed to guide policies
for information security within an organization.
4: What is the difference between a vulnerability and a threat?---
correct precise answer ---
A vulnerability is a weakness in a system that can be exploited by a
threat, which is any potential danger to information or systems
that can exploit a vulnerability to cause harm.
5: What is the role of encryption in data security?--- correct precise
answer ---
Encryption is used in data security to protect sensitive information
by converting it into a code to prevent unauthorized access. It
ensures that data remains confidential and secure during storage
and transmission.
6: What is a firewall and how does it enhance security?--- correct
precise answer ---
, Page 3 of 19
A firewall is a network security device or software that monitors
and controls incoming and outgoing network traffic based on
predetermined security rules. It enhances security by acting as a
barrier between a trusted internal network and untrusted external
networks, like the internet.
7: What is the principle of least privilege?--- correct precise answer
---
The principle of least privilege is a security concept that states
users should be granted the minimum levels of access ?--- correct
precise answer --- or permissions ?--- correct precise answer ---
needed to perform their job functions. This reduces the risk of
accidental or intentional misuse of systems and data.
8: What is a phishing attack?--- correct precise answer ---
A phishing attack is a type of social engineering attack where an
attacker sends fraudulent communications, often through email,
that appear to come from a reputable source to trick individuals
into revealing sensitive information, such as passwords or credit
card numbers.
9: What is multi-factor authentication (MFA)?--- correct precise
answer ---
Multi-factor authentication (MFA) is a security process that
requires users to provide two or more verification factors to gain
access to a resource, such as a system or application. It enhances
security by adding additional layers of verification beyond just a
password.
