.
1. A security administrator is implementing a system where users must provide
a password and a one-time code sent to their mobile device before gaining
access.
A) Single-factor authentication
B) Multi-factor authentication
C) Biometric authentication
D) Mutual authentication
Answer: B) Multi-factor authentication
Explanation: Multi-factor authentication (MFA) requires two or more different
,categories of credentials, such as something you know (password) and something
you have (mobile device).
2. An attacker is sending unsolicited emails that appear to be from a legitimate
bank, tricking users into clicking a link to a fraudulent website to steal
credentials.
A) Vishing
B) Phishing
C) Whaling
D) Pharming
Answer: B) Phishing
Explanation: Phishing is a broad social engineering attack via email. Vishing is
voice-based, and Whaling targets high-level executives specifically.
3. A company discovers that an employee has been using a USB drive to
exfiltrate sensitive customer data from a secure workstation that is not
connected to the internet.
A) Insider threat
B) Script kiddie
C) Hacktivist
D) Shadow IT
Answer: A) Insider threat
Explanation: An insider threat is someone within the organization, such as an
employee or contractor, who uses their authorized access to cause harm or steal
data.
4. Which of the following terms describes a security philosophy where no user
or device is trusted by default, even if they are inside the corporate network
perimeter?
A) Defense in depth
B) Zero trust
C) Air gapping
D) Network segmentation
Answer: B) Zero trust
Explanation: Zero Trust operates on the principle of "never trust, always verify,"
requiring continuous authentication and authorization for every access request.
,5. An organization wants to ensure that data remains confidential even if the
physical hard drives are stolen from a decommissioned server in the data
center.
A) Hashing
B) Full disk encryption
C) Digital signatures
D) Load balancing
Answer: B) Full disk encryption
Explanation: Encryption ensures that the data is unreadable without the correct
decryption key, protecting confidentiality at rest.
6. A security analyst notices a large number of spoofed ICMP packets being sent
to a broadcast address, causing a flood of responses to a single victim's IP
address.
A) SYN flood
B) Smurf attack
C) Replay attack
D) Man-in-the-middle
Answer: B) Smurf attack
Explanation: A Smurf attack is a type of DoS that uses ICMP broadcast traffic to
overwhelm a victim's system with amplified responses.
7. Which component of the CIA triad is being protected when an administrator
implements a RAID 1 configuration to ensure that data remains accessible if a
single drive fails?
A) Confidentiality
B) Integrity
C) Availability
D) Accountability
Answer: C) Availability
Explanation: Availability ensures that systems and data are ready and accessible
to authorized users when needed; redundancy (like RAID) supports this.
8. An attacker gains access to a web server and modifies the price of items in
the database without authorization, causing financial loss to the company.
A) Breach of confidentiality
, B) Breach of integrity
C) Breach of availability
D) Breach of non-repudiation
Answer: B) Breach of integrity
Explanation: Integrity refers to the accuracy and consistency of data;
unauthorized modifications violate this principle.
9. A software developer is using a technique where they provide random,
malformed data to an application's input fields to search for crashes or memory
leaks.
A) Static analysis
B) Fuzzing
C) Code signing
D) Sandboxing
Answer: B) Fuzzing
Explanation: Fuzzing is an automated software testing technique used to find
security vulnerabilities by inputting invalid or random data.
10. Which type of malware is designed to hide its presence on a system by
modifying the operating system's kernel or core files to remain undetected by
antivirus?
A) Ransomware
B) Rootkit
C) Spyware
D) Logic bomb
Answer: B) Rootkit
Explanation: Rootkits are sophisticated malware that operate at a deep level
(often the kernel) to hide themselves and other malicious processes.
11. An organization implements a policy where employees must take five
consecutive days of leave each year to allow for a review of their accounts for
potential fraud.
A) Job rotation
B) Separation of duties
C) Mandatory vacations
D) Least privilege
