Community-vetted answers to 30 common questions about this exam.

Questions from real practice questions

Each Q&A comes from a specific community question — follow the link for its full analysis.

Which Technique Does NOT Help Detect a Honeypot?

Brute force only tests credential or input weaknesses; it generates noisy failed attempts that honeypots log and IDS alerts on, without exposing honeypot-specific fingerprints.

VMware virtual NICs often use known OUI prefixes, so seeing a VMware MAC on a supposed physical host is a strong virtualization artifact and honeypot clue.

Which Security Strategy Best Addresses an Unidentified Vulnerability Breach?

Defense-in-Depth adds layered controls, but it does not by itself define the continuous prediction, prevention, detection, and response cycle the question asks for.

Risk Management identifies and treats risks, but the CEH scenario emphasizes an ongoing comprehensive defense strategy rather than a risk lifecycle process.

How to Confirm XSS When CSP Allows Only Same-Domain Scripts?

The CSP disallows inline scripts, so the browser blocks the payload before execution; a blocked probe cannot prove the input is exploitable.

Yes. If the injected input causes the allowed same-origin script to execute, that demonstrates script execution under the stated CSP and confirms the vulnerability.

What Is the Correct Sequence of Vulnerability-Management Life Cycle Steps?

Monitoring is continuous oversight that confirms fixes hold and surfaces new assets or drift, so it follows remediation and verification. Placing it early (option B) leaves nothing meaningful to monitor.

Verification re-tests the finding to prove the patch or configuration change actually closed it. Verifying before remediation, as options B and D do, checks a system that was never fixed.

What Is Web Server Footprinting in CEH Reconnaissance?

A describes website footprinting or mirroring of site content; CEH defines web server footprinting as system-level data collection such as server names, OS versions, and account details.

A vulnerability scanner actively probes for weaknesses during scanning or vulnerability analysis; footprinting is earlier information gathering that builds the server's system-level profile before exploitation.

Which Attack Technique Did Stephen Use Against Industrial Systems?

The stem asks for the attack technique Stephen used to gain entry; no HMI compromise is described, and the damage is the malware's later impact rather than the initial vector.

The email targeted a specific employee who manages sales software at the operational plant, making it a crafted, recipient-specific social engineering attack.

Which Nmap Switch Helps Evade IDS or Firewalls?

-T selects timing templates such as paranoid or sneaky; slower timing may reduce noise, but it is not the dedicated decoy switch that hides the scanner's source identity.

It adds spoofed decoy IP addresses to the scan so IDS and firewall logs see multiple apparent sources and struggle to identify the real attacker.

How to Keep Full Control of Cloud Encryption Keys at Rest?

That is a BYOK model: the provider's encryption service still uses your key material to encrypt and decrypt, so key custody is shared; client-side encryption keeps all key operations with the client.

No. SSL/TLS protects data in transit between the client and the cloud; data at rest must be encrypted with keys the client controls, as in client-side encryption.

How Should YARA Rules Reduce IDS False Positives from Goodware?

They let the IDS recognize and exclude known-benign files that currently trigger alerts, so analyst time is reserved for genuine threats; malware detection rules can remain active separately.

Broad all-file matching would likely increase noise and false positives, not reduce the goodware alerts; the question asks you to fix the known false-positive source first.

Which Network-Level Session Hijacking Uses Forged ICMP and ARP Spoofing?

TCP/IP hijacking takes over an existing TCP session by manipulating sequence numbers; it does not rely on forged ICMP redirects and ARP spoofing to insert a host into the path.

RST hijacking sends forged TCP reset packets to drop a session, while the MITM ICMP/ARP technique reroutes traffic through the attacker's machine.

Why does secure LDAP enumeration fail without use_ssl in ldap3?

A wrong port would normally stop the TCP/LDAP connection entirely; because the stem says the connection succeeded, the fault is the ldap3 SSL configuration, not the port.

Use Server(host, port=636, use_ssl=True), then bind and search; without use_ssl=True the library does not initialize LDAPS correctly.

Which DNSRecon Command Performs Reverse DNS on an IP Range?

AXFR attempts a full zone transfer from a nameserver and is not a reverse lookup for IP addresses; it usually fails unless the server is misconfigured.

It runs standard enumeration and can return SOA, NS, A, AAAA, MX, SRV, and PTR data depending on the target and nameserver.

Which Zenmap Scan Hides the Scanner's IP While Finding Open Ports?

It spoofs packets from a zombie host and infers open ports by watching the zombie's IPID changes, so the target never sees the tester's real address.

No. -sA maps firewall behavior rather than open TCP ports and still sends probes from the scanner's IP address.

Which Control Best Counters a Broad Range of Social Engineering Techniques?

A honeypot lures and analyzes attackers after they probe the network; it does not stop an employee from being tricked into revealing credentials or granting access.

Only partially — EDR may catch malicious payloads on an endpoint, but it cannot prevent a user from authorizing a fraudulent wire transfer or disclosing information over the phone.

Which Measure Best Prevents Email-Delivered Targeted Malware Attacks?

Scanning is mainly detective and occurs after the attachment lands or runs, so it may miss zero-day or obfuscated malware. Patching closes the vulnerabilities that let the payload execute.

No. Autorun settings control removable drives and optical media; they do not stop a user from opening an email attachment or a document that exploits an unpatched application.
