312-50v13 Exam Dumps : Certified Ethical Hacker Exam (CEH v13 AI)

CEH v13 clarifies that nbtstat is used only for NetBIOS name table enumeration, not for listing shared resources. Tags such as < 20 > indicate file server services, but share enumeration requires tools like net view or SMB enumeration utilities.

Thus, the inability to list shares is due to tool limitation, not service configuration. Option C is correct.

In CEH v13 Cryptography, this threat is formally referred to as “Harvest Now, Decrypt Later” (HNDL). It describes a long-term cryptographic risk where adversaries intercept and store encrypted communications today, even though they cannot decrypt them with current computational capabilities. The expectation is that future quantum computers will be powerful enough to break widely used public-key cryptographic algorithms.

CEH v13 emphasizes that quantum algorithms such as Shor’s Algorithm can theoretically break RSA, DSA, and ECC by efficiently solving integer factorization and discrete logarithm problems. However, the defining feature of this threat is not the act of breaking encryption itself, but rather the strategic collection and storage of encrypted data in advance.

Option C is incomplete because it focuses only on the cryptographic mechanism rather than the threat model. Options B and D are unrelated to the scenario described and refer to quantum communication integrity issues, not long-term cryptographic exposure.

CEH v13 highlights that sensitive data with long confidentiality lifetimes—such as government records, financial data, healthcare information, and intellectual property—is especially vulnerable to this threat. As a result, organizations are encouraged to adopt quantum-resistant (post-quantum) cryptographic algorithms proactively.

Thus, Option A accurately describes the threat model and aligns with CEH v13’s treatment of future cryptographic risks.

The correct answer is D, Split DNS. Split DNS, also called split-horizon DNS, uses separate DNS views or servers for internal and external name resolution. In this configuration, the DNS server in the DMZ provides public-facing records for external users, while the internal DNS server provides private records for internal hosts and services. This prevents sensitive internal hostnames, IP addresses, and infrastructure details from being exposed to the public. CEH networking topics describe DNS as the system that translates hostnames to IP addresses and vice versa, making DNS records valuable during footprinting and enumeration. CEH perimeter-security material also explains that a DMZ is a buffer area between the internal private network and the external public network, used for services that must be reachable externally. DNSSEC is used to protect DNS integrity cryptographically, DynDNS maps changing IP addresses to names, and “DNS Scheme” is not the standard term. Therefore, this configuration is Split DNS.
