PT0-002 · Question #71

The results of an Nmap scan are as follows: Which of the following device types will MOST likely have a similar response? (Choose two.)

The correct answer is B. Public-facing web server D. IoT/embedded device. This question asks to identify device types likely to show specific Nmap scan results, implying an understanding of common open ports for various systems.

Why each option

This question asks to identify device types likely to show specific Nmap scan results, implying an understanding of common open ports for various systems.

ANetwork device

Network devices typically expose management ports like SSH (22), Telnet (23), SNMP (161/UDP), and sometimes HTTP/S for web GUIs, which is a different set than just web services.

BPublic-facing web serverCorrect

A public-facing web server typically exposes HTTP (port 80) and HTTPS (port 443) services, which would be prominently displayed in an Nmap scan of open ports. These services are fundamental for serving web content to the internet.

CActive Directory domain controller

An Active Directory domain controller would primarily expose services like Kerberos (88), LDAP (389/636), DNS (53), SMB (445), and RPC (135), not primarily just web ports.

DIoT/embedded deviceCorrect

Many IoT and embedded devices include web-based administration interfaces (ports 80/443) for configuration and management, leading to similar open port scan results as web servers, alongside potentially other unique device-specific ports. These devices are often resource-constrained and might only run essential services, including a web interface.

EExposed RDP

Exposed RDP refers to a specific service (port 3389) for remote desktop access, not a general device type with a broad set of services that would necessarily resemble a web server.

FPrint queue

A print queue is a service typically running on a server (e.g., port 9100, 515, or SMB 445), not a standalone device type whose primary Nmap response would be described as similar to a web server or IoT device.
