A company runs a high-traffic web application on a single backend server. They are deploying Squid as a reverse proxy to cache static content and reduce backend load. The backend server is already struggling with CPU usage. The administrator wants to maximize the cache hit ratio for static content while minimizing the load on the backend. Which configuration strategy is most effective?

Use 'refresh_pattern' rules to aggressively cache static content (e.g., images, CSS, JS) and set a longer 'minimum_expiry_time'.

Set 'cache_swap_low' to 90 and 'cache_swap_high' to 95 to keep the disk cache as full as possible.

Configure 'cache_peer' with the 'no-query' and 'originserver' options and set 'prefer_direct' to off.

Increase 'cache_mem' and set 'maximum_object_size_in_memory' to a high value to cache more objects in RAM.

A Squid proxy is experiencing slow response times. The administrator runs 'squid -k parse' and sees no errors. They also check the cache.log and see many lines like 'WARNING: Disk cache dir is nearly full'. The cache is configured with a single 100 GB disk. What is the most effective way to improve performance?

Add a second cache_dir on a different disk and reduce the size of the original cache_dir.

Set 'cache_swap_low' to 50 and 'cache_swap_high' to 60 to force more aggressive cache eviction.

Decrease the 'cache_mem' value to free up more RAM for the disk cache.

Increase the 'cache_swap_high' value to 100.
