Sample Questions and Answers

Which of the following BEST describes a vulnerability scan that does not impact system performance or consume network bandwidth excessively?

A. Credentialed scan
B. Non-intrusive scan
C. Exploit-based scan
D. Authenticated scan

Correct Answer: B. Non-intrusive scan

Explanation:
A non-intrusive scan is designed to identify vulnerabilities without exploiting them or consuming significant resources. It uses passive detection techniques and is ideal for environments where performance must not be impacted. Unlike exploit-based or authenticated scans, it avoids direct interaction with system components beyond basic fingerprinting. This makes it safer for production environments and less likely to trigger alerts or cause disruptions.

A security analyst receives multiple reports of failed logins followed by successful access attempts. Which attack is MOST likely taking place?

A. SQL Injection
B. Brute Force
C. Credential Stuffing
D. Session Hijacking

Correct Answer: C. Credential Stuffing

Explanation:
Credential stuffing uses lists of stolen username/password combinations from data breaches to gain unauthorized access to accounts. The pattern of failed logins followed by success suggests that attackers are testing credentials until a match is found. This differs from brute-force attacks, which try random combinations rather than known pairs. It’s essential to detect this early to prevent lateral movement or privilege escalation.

During log analysis, a security analyst notices an abnormal number of DNS requests to random domains. What type of malware is MOST likely involved?

A. Ransomware
B. Botnet
C. Keylogger
D. Command and Control (C2)

Correct Answer: D. Command and Control (C2)

Explanation:
Frequent DNS requests to random or suspicious domains often indicate an attempt to contact a C2 server. This technique allows attackers to bypass firewall rules by using DNS as a covert communication channel. C2 infrastructure is essential for remote control of compromised hosts and often precedes malicious payload delivery or data exfiltration. Monitoring DNS traffic helps identify such activity early.

What is the PRIMARY reason for conducting a tabletop exercise in an organization’s incident response process?

A. To simulate ransomware execution
B. To test the backup systems
C. To evaluate team coordination and response procedures
D. To discover unknown vulnerabilities

Correct Answer: C. To evaluate team coordination and response procedures

Explanation:
Tabletop exercises simulate real-world incident scenarios in a controlled, discussion-based environment. The goal is to evaluate the effectiveness of an incident response plan and ensure all stakeholders understand their roles. These exercises help uncover procedural gaps, improve coordination, and refine communication strategies without interrupting operations. They are a vital part of improving overall security posture.

Which of the following BEST ensures the integrity of collected forensic data during an investigation?

A. Antivirus logs
B. Chain of custody
C. Log aggregation
D. Sandboxing

Correct Answer: B. Chain of custody

Explanation:
The chain of custody is a documented process that tracks the collection, handling, and storage of digital evidence. It ensures that evidence remains untampered and admissible in court. Every person who interacts with the evidence must be recorded to prevent disputes over its authenticity. This is critical in maintaining the credibility of a forensic investigation.

Which of the following metrics is MOST important when prioritizing patching in a vulnerability management program?

A. Patch release date
B. CVSS score
C. Vendor reputation
D. Exploit complexity

Correct Answer: B. CVSS score

Explanation:
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of vulnerabilities. It considers factors like exploitability, impact, and environmental variables. A higher CVSS score indicates greater risk and urgency, making it a vital metric for prioritization. While exploit complexity and vendor reputation matter, CVSS offers a comprehensive and widely accepted basis for decisions in patch management.

A security team notices traffic on port 445 from an unknown host. What is the BEST action to take?

A. Block all outbound HTTPS traffic
B. Quarantine the host for investigation
C. Restart the firewall
D. Disable DNS services

Correct Answer: B. Quarantine the host for investigation

Explanation:
Port 445 is commonly associated with SMB, which is often exploited in attacks like EternalBlue or lateral movement attempts. Unexpected traffic from an unrecognized host may indicate a compromised system. Quarantining the host helps prevent potential spread or data exfiltration while allowing deeper analysis. This proactive containment approach aligns with incident response best practices.

Which type of threat intelligence provides real-time data from sensors and logs within an organization’s environment?

A. Strategic
B. Tactical
C. Technical
D. Operational

Correct Answer: D. Operational

Explanation:
Operational threat intelligence focuses on real-time, actionable information gathered from internal systems, sensors, and logs. It helps teams understand the current threat landscape and take immediate action. This includes information about active attacks, attacker behavior, and infrastructure. Unlike strategic or tactical intel, operational data supports rapid detection and response efforts.

What BEST describes the role of a Security Information and Event Management (SIEM) system?

A. Manages encryption keys across devices
B. Automatically blocks all unauthorized traffic
C. Collects, analyzes, and correlates security data from multiple sources
D. Creates firewall rules based on heuristics

Correct Answer: C. Collects, analyzes, and correlates security data from multiple sources

Explanation:
A SIEM centralizes logs and events from various systems, including firewalls, servers, and applications. It applies correlation rules and analytics to detect suspicious patterns, generate alerts, and support compliance reporting. By aggregating and contextualizing security data, SIEMs help analysts identify threats quickly and respond more effectively, making them essential in modern security operations centers (SOCs).

What technique is MOST effective for detecting a rogue wireless access point?

A. Vulnerability scanning
B. Packet filtering
C. War driving
D. Wireless site survey

Correct Answer: D. Wireless site survey

Explanation:
A wireless site survey uses tools to map all active wireless signals in an area. It helps detect unauthorized or rogue access points broadcasting from within or near an organization. Comparing survey results against a list of approved devices allows quick identification of suspicious activity. This approach is more precise than general scanning or filtering and supports proactive wireless threat mitigation.

An analyst detects an increase in 404 errors in a short period. Which scenario is MOST likely occurring?

A. Brute force attack
B. Path traversal
C. Directory enumeration
D. SQL injection

Correct Answer: C. Directory enumeration

Explanation:
A surge in 404 (Not Found) errors suggests that an attacker is trying to discover valid URLs, directories, or resources on a web server. Directory enumeration involves making automated requests to guess paths to admin panels, scripts, or hidden files. If these attempts fail, they return 404s. Monitoring such anomalies helps detect early-stage reconnaissance.

What is the PRIMARY purpose of using a honeypot in a network?

A. Prevent DDoS attacks
B. Attract and analyze malicious activity
C. Encrypt data in motion
D. Automate access control

Correct Answer: B. Attract and analyze malicious activity

Explanation:
A honeypot is a decoy system designed to lure attackers. It mimics legitimate services to observe and log intrusion attempts without risking production environments. This tactic provides insight into attacker methods, tools, and behavior, helping teams strengthen defenses. Honeypots also divert attackers from valuable assets, increasing detection and response effectiveness.

Which technique allows analysts to identify when a threat actor has successfully pivoted within a network?

A. Signature-based detection
B. Threat hunting
C. Lateral movement detection
D. Social engineering testing

Correct Answer: C. Lateral movement detection

Explanation:
Lateral movement detection involves identifying unauthorized activity where an attacker moves from one compromised system to others within the same network. Detecting this movement helps analysts understand the attack path and stop adversaries before they reach high-value targets. Tools like EDRs and SIEMs are often configured to flag such suspicious inter-host behavior.
