NEWEST 2026/ 2027 TEST BANK| SY0-701 BY COMPTIA EXAM
PREP WITH COMPLETE 350 REAL EXAM QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)
ALREADY GRADED A+ (MOST RECENT!!)
Question 1
A systems administrator would like to set up a system that will make it difficult or
impossible to deny that someone has performed an action. Which of the following is the
administrator trying to accomplish?
A) Non-repudiation
B) Adaptive identity
C) Security zones
D) Deception and disruption
Correct Answer: A) Non-repudiation
Rationale: Non-repudiation ensures that an individual cannot deny having performed a
specific action, typically through digital signatures and audit logs .
Question 2
Which of the following types of controls decreases the likelihood of a cybersecurity
breach occurring?
A) Corrective
B) Transfer
C) Detective
D) Preventive
Correct Answer: D) Preventive
Rationale: Preventive controls are designed to stop security incidents before they occur by
reducing vulnerabilities and blocking threats. Detective controls identify incidents after
they occur; corrective controls restore systems after an incident .
,Question 3
A security analyst is implementing controls to protect the confidentiality of sensitive
customer data. Which of the following BEST addresses this objective?
A) Data backup and recovery procedures
B) Encryption of data at rest and in transit
C) Load balancing across multiple servers
D) Geographic dispersion of data centers
Correct Answer: B) Encryption of data at rest and in transit
Rationale: Encryption directly protects the confidentiality of data by making it unreadable
to unauthorized parties. Backups address availability, load balancing addresses
performance, and geographic dispersion addresses disaster recovery .
Question 4
Which of the following BEST describes the CIA triad?
A) Confidentiality, Integrity, Availability
B) Confidentiality, Identity, Authorization
C) Compliance, Integrity, Availability
D) Confidentiality, Integrity, Authentication
Correct Answer: A) Confidentiality, Integrity, Availability
Rationale: The CIA triad (Confidentiality, Integrity, Availability) is the foundation of
information security. Confidentiality ensures data is accessible only to authorized users;
Integrity ensures data is accurate and unaltered; Availability ensures data is accessible
when needed .
Question 5
Which of the following is an example of a physical security control?
A) Firewall
B) Encryption
C) Biometric reader
D) Intrusion detection system
,Correct Answer: C) Biometric reader
Rationale: Biometric readers (fingerprint, retina scanners) are physical security controls
that restrict access to facilities or systems. Firewalls and IDS are technical controls;
encryption is a cryptographic control .
Question 6
An organization wants to implement the principle of least privilege. Which of the
following BEST describes this principle?
A) Users should have the minimum level of access necessary to perform their job
functions
B) All users should have the same level of access
C) Users should have access to all resources by default
D) Only administrators should have access to sensitive data
Correct Answer: A) Users should have the minimum level of access necessary to
perform their job functions
Rationale: Least privilege ensures users have only the permissions needed to perform their
job functions, reducing the risk of unauthorized access or accidental damage .
Question 7
Which of the following is an example of a defense-in-depth strategy?
A) Using a single firewall to protect the network perimeter
B) Implementing multiple layers of security controls
C) Relying solely on encryption to protect data
D) Using only physical security measures
Correct Answer: B) Implementing multiple layers of security controls
Rationale: Defense-in-depth employs multiple layers of security controls (physical,
technical, administrative) so that if one layer fails, others continue to protect the
organization .
, Question 8
Which of the following is the BEST example of a deterrent control?
A) Firewall rules blocking unauthorized traffic
B) Security cameras and warning signs
C) Intrusion detection system alerts
D) Data backup and recovery procedures
Correct Answer: B) Security cameras and warning signs
Rationale: Deterrent controls discourage potential attackers through the perception of risk
or consequences. Warning signs, security cameras, and access control notices serve as
deterrents by signaling the presence of security measures .
Question 9
A company is implementing a Zero Trust architecture. Which principle is fundamental to
this approach?
A) Trust internal network traffic by default
B) Verify every access request regardless of location
C) Allow all traffic from trusted IP addresses
D) Disable all authentication requirements
Correct Answer: B) Verify every access request regardless of location
Rationale: Zero Trust assumes no implicit trust, regardless of whether the request
originates from inside or outside the network perimeter. Every access request must be
authenticated, authorized, and continuously validated .
Question 10
Which of the following concepts ensures that data has not been altered or tampered
with?
A) Confidentiality
B) Integrity
C) Availability
D) Non-repudiation
