Where in the BIG-IP configuration is an iRule associated with a virtual server?

In the iRule's own configuration, by specifying the virtual server name.

In the virtual server's configuration, under the Resources or iRules section.

In the pool's configuration, under the Members section.

In the node's configuration, under the Monitor section.

A BIG-IP administrator needs to redirect all HTTP requests from `http://example.com` to `https://example.com`. The virtual server is listening on port 80. Which iRule event and command combination will accomplish this?

`when HTTP_REQUEST { HTTP::redirect "https://example.com[HTTP::uri]" }`

`when SERVER_CONNECTED { HTTP::redirect "https://example.com[HTTP::uri]" }`

`when HTTP_REQUEST { pool https_pool }`

`when CLIENT_ACCEPTED { HTTP::redirect "https://example.com[HTTP::uri]" }`

A BIG-IP administrator is troubleshooting a performance issue. An iRule that performs a complex regex on the HTTP request body has been applied to a virtual server. The administrator notices that the BIG-IP's CPU usage is high. What is the most effective way to reduce the CPU impact while still achieving the iRule's goal?

Disable the iRule and rely on the pool member to perform the same check.

Move the iRule to a different virtual server.

Optimize the regex pattern to be more efficient and reduce the frequency of the match.

Increase the number of pool members to distribute the load.
