Resource Analysis

System Performance
Log Analysis
Solve
As a senior DevOps engineer, you are tasked with diagnosing performance issues on a Linux server running Ubuntu 20.04. The server hosts several critical applications, but lately, users have been experiencing significant slowness. Initial monitoring shows that CPU and memory utilization are consistently high. To identify the root cause, you check the output of `top` and `ps` commands, which indicate that a particular process is consuming an unusually high amount of resources. However, the process name is generic and does not clearly indicate which application or service it belongs to. You also examine `/var/log/syslog` for any unusual entries but find nothing out of the ordinary. Based on this situation, which of the following steps would most effectively help you identify and resolve the performance issue?
A: Increase the server's physical memory and CPU capacity.
            B: Use the `lsof` command to identify the files opened by the suspect process.
            C: Reboot the server to reset all processes.
            D: Examine the `/etc/hosts` file for any incorrect configurations.
            E: Run the `netstat` command to check for abnormal network activity.
            F: Check the crontab for any recently added scheduled tasks.

Solve
You are in charge of developing a Bash script for setting up a continuous integration pipeline for a web application. The source code is hosted in a Git repository. The script's goals include:
            
            1. Ensuring the local copy of the repository in /var/www/html is updated to the latest version.
            2. Creating a .env file with APP_ENV=production in the project root if it doesn't already exist.
            3. Running a test suite with ./run_tests.sh and handling any test failures appropriately.
            4. Logging the current timestamp and commit hash in deployment_log.txt in the project root if tests pass.
            
            Which of the following script options would most effectively and safely accomplish these tasks?
