nmap (Network Mapper) is the best tool in this scenario. It can scan the 192.168.1.0/24 subnet to discover live hosts, open ports (like Telnet on port 23), and device types. It’s ideal for mapping and auditing the network.

A. dig is a DNS lookup tool; not useful for identifying hosts on a subnet.

C. tracert shows the path packets take to a destination, not for host discovery.

D. telnet is the protocol being used, not a tool for scanning or identifying devices.

If the IP phone works but the workstation doesn ' t, it indicates that the Voice VLAN is functioning correctly, but the Data VLAN (C) is either misconfigured or missing. The workstation typically connects through the phone, which tags voice and data traffic separately using VLANs.

B. Native VLAN is for untagged traffic on trunk ports, but doesn’t control access directly.

Enterprise authentication (such as WPA2-Enterprise) utilizes unique credentials for each user, typically integrating with an authentication server like RADIUS. This allows for tracking and logging user activity, ensuring that all connections can be traced back to individual users. PSKs (Pre-Shared Keys) are shared among users and do not provide individual accountability. Captive portals can identify users but are less secure than enterprise authentication, and Wired Equivalent Privacy (WEP) is outdated and not recommended for security purposes.

Malware refers to any malicious software that can exfiltrate confidential data, including spyware, trojans, and rootkits. This fits the scenario where unauthorized data transfer is occurring.

Breakdown of Options:

A. Adware – Displays ads, does not typically steal data.

B. Ransomware – Encrypts files but does not exfiltrate data.

C. Darkware – Not a real cybersecurity term.

D. Malware – Correct answer. Malicious software is responsible for unauthorized data exfiltration.
