Indirect evidence is evidence that does not directly prove a fact, but rather implies or infers it from other facts or circumstances. Indirect evidence is also known as circumstantial evidence or corroborating evidence. A video of a suspect entering a data center that was captured on the same day that files in the same data center were transferred to a competitor is an example of indirect evidence, because it does not directly show that the suspect was involved in the file transfer, but rather suggests a possible connection or correlation between the two events. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 5: Security Policies and Procedures, Lesson 5.3: Digital Forensics, Topic 5.3.1: Evidence, page 5-24.

Full packet captures are essential for troubleshooting security and performance issues as they provide detailed information on network traffic (option B). They also allow for reassembling fragmented traffic from raw data, enabling analysts to review complete transactions or sessions (option C). References := Cisco Cybersecurity Operations Fundamentals - Module 3: Network Data and Event Analysis

Reflective XSS, also known as Non-Persistent XSS, occurs when an attacker sends a malicious script to a user through a web application, and the script is executed immediately in the user’s browser without being stored on the server. This type of attack is typically carried out by including the malicious script in a URL, which is then sent to the victim. When the victim clicks on the link, the script runs in their browser, reflecting the attacker’s actions without storing the payload for repeated use12. References: OWASP Foundation’s documentation on Cross-Site Scripting (XSS) provides detailed information on the different types of XSS attacks, including Reflective XSS

 Full packet capture requires the largest amount of storage space because it involves recording all packets that pass through a network, including all headers and payloads. This type of data collection is comprehensive and allows for detailed analysis, but due to the volume of data it encompasses, it demands significant storage capacity1.

References := The Cisco Secure Network Analytics Data Store Design Guide discusses the storage requirements for different types of network data collection, highlighting the substantial storage needs for full packet captures1.
