An NGINX caching proxy serves a mix of static and dynamic content. The team wants to ensure that requests with a query string are not cached, to avoid caching personalized search results. Which configuration achieves this?

Include $query_string in the cache key.

Set proxy_cache_bypass $is_args;

Set cache_valid 0 for responses with a query string.

Set proxy_cache off for the location.

A company runs a multi-tenant SaaS platform. Each tenant has a unique subdomain. The platform uses NGINX as a reverse proxy to a backend that generates tenant-specific content. The team wants to cache responses to reduce backend load, but must ensure that one tenant never receives another tenant's data. What is the most important configuration consideration?

Set a short cache_valid time to minimize stale data.

Disable caching for all requests to ensure data isolation.

Include the tenant identifier (e.g., subdomain) in the cache key.

Use a large keys_zone to store more entries.
