The correct answer is D. aireplay-ng.

The scenario describes transmitting crafted wireless frames to interrupt active client connections so that the clients reconnect and generate fresh authentication handshakes. In the Aircrack-ng suite, aireplay-ng is the component used for packet injection and deauthentication-style attacks.

The referenced wireless testing material shows aireplay-ng being used to force client deauthentication during a handshake capture workflow, while airodump-ng is used to capture traffic, airmon-ng is used to enable monitor mode, and aircrack-ng is used later for cracking captured handshakes or keys .

Option A. airodump-ng is incorrect because it captures and monitors wireless traffic.

Option B. airmon-ng is incorrect because it places the wireless adapter into monitor mode.

Option C. aircrack-ng is incorrect because it performs the cracking phase after useful capture material has been collected.

Option D. aireplay-ng is correct because it injects frames, including deauthentication frames, to stimulate handshake capture.

Therefore, the best answer is D. aireplay-ng.

The correct answer is D. IPsec (Internet Protocol Security). The question specifically asks for a Layer 3 protocol that can provide end-to-end encryption for FTP traffic. IPsec operates at the Network Layer (Layer 3) of the OSI model and secures IP communications by providing confidentiality, integrity, authentication, and anti-replay protection.

Since standard FTP transmits usernames, passwords, and data in plaintext, it is vulnerable to packet sniffing and man-in-the-middle attacks. By implementing IPsec, all IP packets exchanged between the client and server can be encrypted regardless of the application being used. This means FTP traffic can be protected without modifying the FTP application itself.

Option A (FTPS) uses SSL/TLS to secure FTP but operates at higher layers. Option B (SFTP) is a secure file transfer protocol that runs over SSH and is considered an application-layer solution rather than a Layer 3 protocol. Option C (SSL) provides transport/session-layer encryption and is not a Layer 3 protocol.

CEH Exam Tip:

IPsec = Layer 3 (Network Layer) Encryption

SSL/TLS = Higher-layer Encryption

SFTP = SSH-based Secure File Transfer

FTPS = FTP over SSL/TLS

Therefore, the best answer is D. IPsec.

CEH v13 identifies spear-phishing as one of the most effective and targeted social engineering methods. It involves crafting highly personalized messages that reference real events, internal processes, or upcoming activities to build credibility and reduce suspicion. In this scenario, referencing board meetings—an event executive assistants frequently handle—creates a believable and urgent context for the request. CEH emphasizes that personalization significantly increases success rates because recipients perceive the sender as someone with legitimate access to internal information. A phone call impersonating IT support (Option B) is less convincing for retrieving agenda access-specific credentials. Mass phishing (Option C) lacks personalization and is easily flagged. LinkedIn social engineering (Option D) is long-term and less effective for obtaining immediate credentials. Therefore, a tailored spear-phishing email is the most effective approach.

The correct answer is B. Rogue AP because the scenario describes an unauthorized access point that has been physically connected to the internal wired network and is providing network access on the corporate VLAN without approval or inventory records. In CEH-aligned wireless security concepts, a rogue access point is any AP that is installed on an organization’s network without authorization, creating an unmanaged entry point that bypasses standard security controls. The key indicators here are: it is “previously unknown,” “neither provisioned by IT nor listed in the asset inventory,” and it is “physically connected to the hospital’s internal switch.”

The fact that the device is issuing IP addresses suggests it may be running a DHCP service or bridging into the internal network in a way that places clients directly onto the corporate VLAN. This can allow attackers to gain internal access from nearby wireless range and can also cause network instability if its DHCP responses conflict with the legitimate DHCP infrastructure. Additionally, the device “relaying internal traffic and providing remote connectivity back to an external host” points to an attacker using it as a covert foothold—effectively an unauthorized wireless bridge into the internal network and a channel for command-and-control or remote access.

Why not the other options: a misconfigured AP implies a legitimate AP deployed by IT but configured insecurely (weak encryption, default credentials, poor segmentation). A honeypot AP is typically deployed deliberately (often by defenders) to attract attackers for detection and research, not stealthy backhaul to an external host. An evil twin AP is a spoofed wireless AP that impersonates a legitimate SSID to lure victims; it does not necessarily require being physically plugged into the internal switch, and the defining trait is impersonation of a real AP/SSID. The defining trait here is unauthorized installation on the wired network, which is most directly a rogue access point.
