Explanation:
A false positive is a result that indicates a vulnerability or a problem when there is none. In this case, the vulnerability scanning report shows that the telnet service on port 23 is open and uses an insecure network protocol. However, the security analyst performs a test using nmap and a script that checks for telnet encryption support. The result shows that the telnet server supports encryption, which means that the data transmitted between the client and the server can be protected from eavesdropping. Therefore, the reported vulnerability is a false positive and does not reflect the actual security posture of the server. The security analyst should verify the encryption settings of the telnet server and client and ensure that they are configured properly3.

Explanation:
Zero Trust architecture is based on the principle of "never trust, always verify," meaning all traffic between systems must be authenticated and authorized before communication is allowed, regardless of network location.
Policy enforcement (A) is important but broader. Authentication (B) is a component of Zero Trust, and confidentiality (D) refers to data protection, not access validation.
Zero Trust is a modern security framework emphasized in Security Architecture for securing enterprise environments 【 6: Chapter 3†CompTIA Security+ Study Guide 】 .

Explanation:
The act described is espionage, where classified information is stolen and provided to adversaries or unauthorized parties, usually for political, military, or strategic advantage.
Data exfiltration (B) is the technical act of stealing data but doesn’t specify motivation. Financial gain (C) or blackmail (D) could be motivations but are not clearly indicated here.
Espionage is a classic threat actor motivation outlined in the Threats domain 【 6: Chapter 2†CompTIA Security+ Study Guide 】 .

Explanation:
Classification is the process of assigning a level of sensitivity and handling requirements to data, which informs its lifecycle management, retention, and disposal methods. In regulated industries such as banking, proper data classification ensures that data subject to legal or regulatory requirements is destroyed according to those requirements at the end of its retention period. This directly guides how the data should be handled and disposed of.
Reference: CompTIA Security+ SY0-701 Official Study Guide, Domain 5.4: "Classification dictates data handling, storage, retention, and destruction policies in compliance with regulatory requirements."
Exam Objectives 5.4: “Given a scenario, implement data security and privacy practices.”

Explanation:
Monitoring outbound traffic is essential for detecting unauthorized data exfiltration from a system. A new vulnerability that allows malware to move data unauthorizedly would typically attempt to send this data out of the network. By monitoring outbound traffic, security tools can detect unusual data transfers, trigger alerts, and help prevent the exfiltration of sensitive information.
