Citrix Endpoint Management Administration — Question 55

Scenario: A Citrix Engineer needs to ensure that the flow of traffic to a web application does NOT overwhelm the server. After thorough testing, the engineer determines that the application can handle a maximum of 3,000 requests per minute. The engineer builds a limit identifier, rl_maxrequests, to enforce this limitation.
Which advanced expression can the engineer write in the Responder policy to invoke rate limiting?

Answer options

• A. SYS.CHECK_LIMIT(“rl_maxrequests”)
• B. SYS.CHECK_LIMIT(“rl_maxrequests”).CONTAINS(“Busy”)
• C. SYS.CHECK_LIMIT(“rl_maxrequests”).IS_VALID
• D. SYS.CHECK_LIMIT(“rl_maxrequests”).GE(3000)

Correct answer: A

Explanation

The correct answer, A, uses SYS.CHECK_LIMIT to check the specified limit identifier, rl_maxrequests, which directly relates to enforcing the request cap. Options B and C do not apply the rate limiting correctly, and option D checks if the limit is greater than or equal to 3000, which is not the intended use for invoking rate limiting.
