Ahmed has hundreds of systems spread across multiple locations and wants to better handle the amount of data that they create. Which of the following two technologies can help with this?

Using log aggregation to pull together logs from multiple sources, and performing collection and initial analysis on log collectors can help centralize and handle large log volumes. Capturing packets is useful for network traffic analysis to identify issues or security concerns. Security monitoring is an overall function for security information and event management (SIEM) and doesn’t specifically help in this case. Both sentiment analysis and user's behavior analysis are targeted at users and groups rather than at how data is collected and managed.
