How do the master process and worker processes interact in NGINX?

Workers periodically restart the master process to apply configuration changes

The master process handles all network I/O and passes data to workers

The master process spawns, monitors, and signals worker processes

Workers send requests to the master process for processing

An NGINX server is configured with 'user nginx;'. The server needs to write to a cache directory /var/cache/nginx. The directory is owned by root:root with permissions 755. What should the administrator do to allow workers to write to the cache?

Change the owner of /var/cache/nginx to nginx

A security policy requires that NGINX worker processes run with the least privilege necessary. The server only serves static files and does not need to write to any files. What is the most appropriate user for the worker processes?

The root user, to ensure all files are accessible

The 'www-data' user, which is the default on Debian

A dedicated 'nginx' user with read-only access to the web root

The 'nobody' user, which has no permissions
