How This Mock Exam Matches the Real EC-Council CEH Exam

Sample Questions from the Mock Exam Pool

Here are 10 real questions from the FlashGenius CEH question bank that powers this mock exam, with answers and detailed explanations:

Sample Question 1 — Cloud Computing

You are tasked with assessing the resilience of a cloud-based application against web attacks. Which of the following techniques would best help identify potential SQL injection vulnerabilities in the application?

  1. A. Manual code review of application source code
  2. B. Using a web vulnerability scanner with SQLi detection capabilities (Correct answer)
  3. C. Performing a brute force attack on the application login page
  4. D. Deploying a DDoS attack to observe how the application handles traffic spikes

Correct answer: B

Explanation: Using a web vulnerability scanner with SQLi detection capabilities is effective for identifying SQL injection flaws in web applications. Manual code review (option A) may miss issues without direct application access, and options C and D are not relevant to SQL injection testing.

Sample Question 2 — Cloud Computing

While performing a security assessment on a company's cloud infrastructure, you discover that the company is using an outdated version of a popular cloud management interface. What should be your primary concern regarding this discovery?

  1. A. The potential for data loss due to outdated software.
  2. B. The inability to scale resources effectively.
  3. C. The increased risk of known vulnerabilities being exploited. (Correct answer)
  4. D. The lack of support for new cloud features.

Correct answer: C

Explanation: Outdated software often contains known vulnerabilities that can be exploited by attackers, making this the primary concern. While other options may also be issues, they do not pose immediate security risks like option C.

Sample Question 3 — Cryptography

A client asks you to ensure that their corporate emails are being transmitted securely. Which of the following measures would best verify the use of strong encryption in email transmission?

  1. A. Check the SMTP server configuration for STARTTLS support. (Correct answer)
  2. B. Attempt to decrypt email traffic using a rainbow table.
  3. C. Capture email traffic and analyze it with a regular expression tool.
  4. D. Review user email clients for PGP or S/MIME encryption settings.

Correct answer: A

Explanation: Checking for STARTTLS support ensures that the SMTP server is capable of encrypting email transmissions. Options B and C are inappropriate for verifying encryption standards, and option D is not focused on transmission security.

Sample Question 4 — Cryptography

You are conducting a security audit on a company's file server. What is the best approach to assess the security of the stored files against unauthorized decryption?

  1. A. Execute a keylogger on the server to capture encryption keys.
  2. B. Use a vulnerability scanner to find known weaknesses in file encryption implementations.
  3. C. Analyze encryption policies and key management practices for compliance with best practices. (Correct answer)
  4. D. Attempt to crack encrypted files using a brute-force attack.

Correct answer: C

Explanation: Analyzing encryption policies and key management practices helps ensure compliance with best practices, protecting against unauthorized decryption. Option A is unethical, B is not specific to encryption, and D may be illegal and impractical.

Sample Question 5 — Denial-of-Service

While testing the security of a corporate network, you notice that the network has multiple critical services running on the default ports. To evaluate the potential for DoS attacks, which tool should you utilize to perform a SYN flood attack?

  1. A. THC-SSL-DOS
  2. B. LOIC
  3. C. Nessus
  4. D. Hping3 (Correct answer)

Correct answer: D

Explanation: Hping3 can be used to perform SYN flood attacks by sending numerous SYN packets to a target server, which is a classical form of DoS attack. THC-SSL-DOS is used for SSL-based flooding, LOIC is used for simple flooding attacks, and Nessus is a vulnerability scanner.

Sample Question 6 — Denial-of-Service

A client has requested a security test on their network to identify any vulnerabilities to application layer denial-of-service attacks. Which tool would be best to simulate this type of attack on their HTTP services?

  1. A. Slowloris (Correct answer)
  2. B. Wireshark
  3. C. Hydra
  4. D. Netcat

Correct answer: A

Explanation: Slowloris is a tool designed to perform application layer DoS attacks, specifically targeting HTTP servers by keeping many connections open and inactive. Wireshark is for packet analysis, Hydra is used for password attacks, and Netcat is a network utility tool not specifically for DoS attacks.

Sample Question 7 — Enumeration

A client has asked you to identify all shared resources on their network. Which command would be most effective in listing network shares on a Windows domain?

  1. A. net share
  2. B. nbtstat -n
  3. C. net view (Correct answer)
  4. D. ping

Correct answer: C

Explanation: The 'net view' command is used to display a list of shared resources in a Windows domain. 'net share' displays shares on the local computer, 'nbtstat -n' shows local NetBIOS names, and 'ping' checks connectivity.

Sample Question 8 — Enumeration

You are working on a Linux environment and need to find open network ports and their associated services. Which command can provide this information?

  1. A. ifconfig
  2. B. netstat -tuln (Correct answer)
  3. C. iptables
  4. D. tcpdump

Correct answer: B

Explanation: 'netstat -tuln' is used to list open ports and associated services on Linux. 'ifconfig' displays network interface configurations, 'iptables' is for configuring firewall rules, and 'tcpdump' captures network packets.

Sample Question 9 — Evading IDS, Firewalls, and Honeypots

During a penetration test, you identify a honeypot designed to detect unauthorized access. What is the most ethical way to handle this discovery?

  1. A. Avoid interacting with the honeypot and report its presence (Correct answer)
  2. B. Attempt to disable the honeypot
  3. C. Use it to gather intelligence on the network
  4. D. Ignore it and continue testing as planned

Correct answer: A

Explanation: The most ethical course of action is to avoid interaction with the honeypot to prevent alerting system administrators, and report its presence to the client. Disabling or exploiting the honeypot is unethical and could breach the terms of engagement.

Sample Question 10 — Evading IDS, Firewalls, and Honeypots

A company's external firewall is configured to allow HTTP and HTTPS traffic only. How can you exploit this configuration to bypass the firewall rules during a penetration test?

  1. A. Use HTTP tunneling to encapsulate non-HTTP traffic (Correct answer)
  2. B. Use FTP to transfer files
  3. C. Send ICMP packets for data transfer
  4. D. Conduct an SQL Injection attack

Correct answer: A

Explanation: HTTP tunneling can encapsulate other types of traffic within HTTP requests, allowing it to pass through the firewall. FTP and ICMP are typically blocked if not explicitly allowed, and SQL Injection does not address firewall bypass directly.

CEH Full Mock Exam FAQ

Is this CEH full mock exam really free?

Yes. The full-length 125-question CEH mock exam is completely free with no signup or credit card required. You get instant scoring, a per-domain performance breakdown, and detailed explanations for every question.

How closely does this mock exam match the real EC-Council CEH exam?

It mirrors the real CEH 312-50 structure: 125 multiple-choice questions with a 4-hour timer, and question distribution weighted by the official EC-Council exam blueprint across all 20 CEH modules — from Footprinting and Reconnaissance to Cloud Computing and Cryptography.

What score should I aim for on the full mock exam?

Aim for 70% or higher. The real CEH exam uses a variable cut score (typically 60–85% depending on question difficulty), so consistently scoring above 70% on full-length timed mocks is a solid readiness indicator.

What happens when the 4-hour timer runs out?

The exam submits automatically, just like the real test. Any unanswered questions are marked incorrect, and you immediately see your score, per-domain breakdown, and full answer review.

Can I retake the mock exam with different questions?

Yes. Each attempt draws a fresh weighted selection from our 1,500+ CEH question pool, so you can retake the mock exam multiple times and see new questions.

Should I take the quick test or the full mock exam first?

Start with the 10-question quick test to gauge your baseline, drill weak domains with the module-specific practice tests, then take the full 125-question mock exam to build test-day stamina and pacing.
