What is the effect of the 'user' directive in nginx.conf?

It sets the user and group for the master process

It specifies the user for accessing upstream servers

It restricts which users can access the NGINX configuration file

It defines the user and group under which worker processes run

An NGINX server is experiencing high CPU usage. The administrator suspects that worker processes are consuming too many resources. What is the most effective way to limit the number of worker processes?

Set 'worker_priority 0;' in the main context

Set 'worker_processes 2;' in the main context

Set 'worker_connections 1024;' in the events context

Set 'worker_rlimit_nofile 1024;' in the main context

An administrator is troubleshooting an NGINX server where workers are running as root. The administrator wants to change this to a non-privileged user. After adding 'user nginx;' to nginx.conf and reloading, the workers still run as root. What is the most likely reason?

The reload command was not executed

The 'user' directive was added to the wrong context

The 'user' directive is case-sensitive and should be 'User'

The nginx user does not exist on the system

In NGINX, what is the primary role of the master process?

To cache static files in memory for faster delivery

To read configuration, manage worker processes, and perform privileged operations

To handle incoming client connections and serve content

To execute application code for dynamic content generation
