Which command configures a rate-limiting policy to threshold 1,000 requests per second?

• A. HTTP.REQ.LIMIT(<limit_identifier>)
• B. SYS.CHECK.LIMIT(<limit_identifier>)
• C. SYS.CHECK.LIMIT(<limit_identifier>) || CONNECTION.IP.LIMIT(<limit_identifier>)
• D. SYS.CHECK.LIMIT(<limit_identifier>) || HTTP.REQ.LIMIT(<limit_identifier>)

Answer: (B)

The rate limit is defined at the system level by a limit check. SYS.CHECK.LIMIT creates a global rate-limit definition (identified by a limit_identifier) that specifies how many events per second are allowed. When you want a global threshold like 1,000 requests per second, you configure this limit through SYS.CHECK.LIMIT, then apply it in a policy to enforce the global rate. Other commands focus on more specific scopes (such as per HTTP request or per IP), or require combining with the system limit, but they don’t establish the standalone global threshold by themselves. So, for configuring a global rate limit of 1,000 requests per second, SYS.CHECK.LIMIT() is the appropriate command.
