   An NGINX configuration has `keepalive_requests 100;` at the `http` block level. A `server` block for a high-traffic site sets `keepalive_requests 50;`. A `location` block within that server for `/api` does not define `keepalive_requests`. What is the effective `keepalive_requests` value for requests to `/api`?

   • A50, because the location inherits from the server block, which overrides the http block.
   • BThe default value of 1000, because the location block resets the value.
   • C50, but only if the location block explicitly includes `keepalive_requests 50;`.
   • D100, because the http block's value is the highest-level and always applies.

   An administrator is configuring NGINX and notices that a directive set at the `http` block level is not being applied to a `server` block. The directive is `add_header`. The `server` block does not define `add_header`. What is the most likely reason for this behavior?

   • AThe `server` block has a syntax error that prevents inheritance from applying.
   • BThe `http` block is not a valid parent context for `add_header`.
   • CThe `add_header` directive is an inheritance exception and must be defined in each context where it is needed.
   • DThe directive is deprecated and NGINX ignores it in newer versions.

   An NGINX configuration has `sendfile on;` at the `http` block level. A `server` block for a large file download service does not define `sendfile`. A `location` block within that server for `/downloads` sets `sendfile off;`. What is the effective `sendfile` setting for requests to `/downloads`?

   • AOn, because the http block's setting is the highest-level and always applies.
   • BOff, but only for the exact `/downloads` path; other paths in the server will use the http block's setting.
   • COff, because the location block overrides the inherited value from the server block.
   • DOn, because the server block inherits from http, and the location cannot override it.

   An administrator sets `server_tokens off;` at the `http` block level to hide NGINX version information. They notice that responses from a specific `server` block still show the version. The `server` block does not define `server_tokens`. What could explain this behavior?

   • AThe `server_tokens` directive is an inheritance exception and must be set in each server block.
   • BThe `server` block has a `location` that overrides the setting.
   • CThe directive only applies to the main context, not the http block.
   • DThe `http` block setting is being overridden by a default value in the server block.
