1. Which of the following is the main function of a security operations center
(SOC)?
A. To perform software development
B. To monitor and respond to cybersecurity incidents
C. To manage network infrastructure
D. To perform regular hardware maintenance
Answer: b) To monitor and respond to cybersecurity incidents
Rationale: A Security Operations Center (SOC) is responsible for monitoring
security threats, detecting incidents, and responding to them promptly to minimize
damage.
2. What is a "Man-in-the-Middle" (MITM) attack?
A. An attack where the attacker intercepts and alters communication between two
parties
B. An attack that spreads malware across multiple devices
C. An attack that encrypts data and demands a ransom for decryption
,D. An attack that floods a network with traffic to cause it to crash
Answer: a) An attack where the attacker intercepts and alters communication
between two parties
Rationale: A MITM attack occurs when an attacker secretly intercepts and
potentially alters the communication between two parties without their knowledge.
3. What does the term "phishing" refer to?
A. A type of malware
B. Sending unsolicited emails to collect personal information
C. An attack that blocks network access
D. A technique to hide network traffic
Answer: b) Sending unsolicited emails to collect personal information
Rationale: Phishing involves sending fraudulent communications that appear to be
from a legitimate source to deceive recipients into sharing sensitive information.
4. What is the main purpose of a Public Key Infrastructure (PKI)?
A. To establish a secure channel for communication
B. To manage user access control
, C. To monitor and log network activities
D. To provide secure email encryption and authentication
Answer: a) To establish a secure channel for communication
Rationale: PKI is used to manage digital certificates and public-private key pairs,
enabling secure communication, authentication, and data encryption.
5. What is the process of converting plaintext into ciphertext to protect its
confidentiality?
A. Hashing
B. Encryption
C. Authentication
D. Decryption
Answer: b) Encryption
Rationale: Encryption is the process of converting plaintext into ciphertext to
prevent unauthorized access to data.
6. What is the primary goal of cybersecurity?
A. To reduce network traffic
(SOC)?
A. To perform software development
B. To monitor and respond to cybersecurity incidents
C. To manage network infrastructure
D. To perform regular hardware maintenance
