Sample Questions

One example from each Security+ domain

Domain 1: General Security ConceptsObjective 1.1

A security administrator implements a system that requires users to swipe a badge and enter a PIN before accessing the data center. This is an example of which security concept?

A. Single sign-on
B. Multifactor authentication
C. Role-based access control
D. Discretionary access control

AI Explanation

This describes multifactor authentication (MFA) because it requires two different types of factors: something you have (badge) and something you know (PIN). SSO relates to accessing multiple systems with one login. RBAC and DAC are authorization models, not authentication methods.

Domain 2: Threats, Vulnerabilities & MitigationsObjective 2.2

An attacker sends an email that appears to be from the CEO, urgently requesting a wire transfer to a new vendor. This attack is BEST described as:

A. Vishing
B. Smishing
C. Spear phishing
D. Whaling

AI Explanation

Whaling is a phishing attack that specifically targets high-level executives or impersonates them. While this is also spear phishing (targeted), whaling is more specific because it involves executive impersonation. Vishing uses voice calls, and smishing uses SMS.

Domain 3: Security ArchitectureObjective 3.1

A company wants to allow employees to access internal applications from personal devices without installing corporate software. Which solution BEST meets this requirement?

A. VDI (Virtual Desktop Infrastructure)
B. MDM (Mobile Device Management)
C. DLP (Data Loss Prevention)
D. NAC (Network Access Control)

AI Explanation

VDI provides virtual desktop sessions that employees can access from any device without installing software locally. MDM requires software installation on devices. DLP prevents data exfiltration. NAC controls network access but doesn't provide application access.

Domain 4: Security OperationsObjective 4.3

During an incident response, the security team takes a forensic image of a compromised server before disconnecting it from the network. Which incident response phase does this represent?

A. Preparation
B. Detection and Analysis
C. Containment, Eradication, and Recovery
D. Post-Incident Activity

AI Explanation

Taking a forensic image and disconnecting the server are containment activities. The team is preserving evidence (forensic image) while stopping the spread (disconnecting). Preparation happens before incidents. Detection identified the compromise. Post-incident is lessons learned.

Domain 5: Security Program ManagementObjective 5.1

An organization must comply with GDPR for its European customers. Which of the following would be the FIRST step in achieving compliance?

A. Implement encryption on all databases
B. Conduct a data inventory and mapping exercise
C. Train all employees on GDPR requirements
D. Hire a Data Protection Officer

AI Explanation

Before implementing any controls, you must understand what personal data you have and where it flows. Data inventory and mapping identifies what needs protection. Encryption, training, and hiring a DPO are all important but come after you understand your data landscape.
