c) To combine log data from multiple sources into a single view.
2. Which of the following is NOT a benefit of using composite logs?
a) Centralized visibility of system events. b) Simplified debugging of system issues. c) Improved performance due to reduced log file size. d) Automatic log analysis and reporting.

Scenario: Imagine you have two separate log files: app_log.txt and server_log.txt.
app_log.txt contains information about events within your application, like user logins and requests. server_log.txt contains information about the server's performance, like CPU usage and memory usage.
Task: Using a text editor or a simple scripting language (like Python or Bash), create a new composite log file called combined_log.txt that merges the contents of both app_log.txt and server_log.txt.
Hint: You can use commands like cat or echo to combine the files, and redirect the output to a new file.
Here's a simple way to combine the log files using Bash:
bash cat app_log.txt server_log.txt > combined_log.txt
This command uses `cat` to read the contents of both `app_log.txt` and `server_log.txt` and redirects the output to a new file called `combined_log.txt`.
