A+ Graded
1. Which of the following is the BEST description of the CIA triad?
A) Control, Integrity, Access
B) Confidentiality, Integrity, Availability
C) Compliance, Integrity, Authorization
D) Confidentiality, Identification, Auditing
Answer: B
Rationale: The CIA triad stands for Confidentiality (protecting information from unauthorized access),
Integrity (ensuring data is accurate and unaltered), and Availability (ensuring systems and data are
accessible when needed). This is a core framework in security principles.
2. What type of security control is a firewall?
A) Physical
B) Managerial
C) Technical
D) Administrative
Answer: C
Rationale: A firewall is a technical control because it uses software and hardware to prevent or restrict
network traffic based on rules.
,3. Which term describes controls that identify and record unwanted activity?
A) Preventive
B) Detective
C) Compensating
D) Directive
Answer: B
Rationale: Detective controls are meant to detect and alert — for example, intrusion detection systems
(IDS), audit logs, and monitoring tools.
4. A security team installs locked filing cabinets to physically store sensitive documents, creates a
mandatory cleandesk policy with monthly audits, and reduces printed documents by moving to a
paperless workflow. How should these controls be classified?
A) Preventive, detective, and corrective
B) Preventive, preventive, and corrective
C) Detective, preventive, and corrective
D) Corrective, detective, and preventive
Answer: B
Rationale: The locked filing cabinets are preventive (stop the behavior). The cleandesk policy with audits
is also preventive because it enforces ongoing compliance. The paperless workflow is corrective because
it removes the root cause.
5. Which cryptographic concept converts plaintext into ciphertext?
A) Hashing
,B) Encryption
C) Tokenization
D) Auditing
Answer: B
Rationale: Encryption transforms readable data into an unreadable format (ciphertext) using keys so
that only authorized parties can decrypt it later.
6. What is the primary use of hashing in security?
A) Encrypting data for confidentiality
B) Ensuring data integrity
C) Providing access control
D) Auditing events
Answer: B
Rationale: Hashing produces a fixedlength output (hash) from input data; changes in the input produce
different hashes, so hashing helps verify that data hasn't been altered.
7. A security analyst wants to ensure that the privileges granted to an individual align with their role
within the organization. What is the primary concept the analyst should implement?
A) Mandatory Access Control (MAC)
B) RoleBased Access Control (RBAC)
C) Discretionary Access Control (DAC)
D) AttributeBased Access Control (ABAC)
Answer: B
, Rationale: RoleBased Access Control (RBAC) assigns permissions based on a user's role within the
organization, ensuring that privileges align with job responsibilities.
8. What is the main goal of Zero Trust architecture?
A) Trust all users inside the network by default
B) Enforce leastprivilege and continuously verify every access request
C) Eliminate the need for authentication
D) Allow all traffic from trusted IP addresses
Answer: B
Rationale: Zero Trust architecture enforces leastprivilege access and continuously verifies every access
request, never trusting any user or device by default.
9. Which of the following is an example of a physical security control?
A) Firewall
B) Encryption
C) Security guard
D) Access control list (ACL)
Answer: C
Rationale: A security guard is a physical control because it involves human presence to protect physical
assets. Firewalls and ACLs are technical controls, and encryption is a cryptographic control.
10. What does the "A" in the AAA framework stand for in cybersecurity?
