To configure a rate-limiting policy setting DNS requests to a threshold of 1,000 per second, the administrator needs to define the system-level limit and the specific HTTP request limit. The command SYS.CHECK.LIMIT(<limit_identifier>) is used to define a system-level limit, while HTTP.REQ.LIMIT(<limit_identifier>) sets a limit on the rate of HTTP requests. Combining these two expressions using the '||' operator properly applies the rate limit based on both criteria.
B conf order: 1. Stream Selector: entity for which you want to throttle access 2. Limit Identifier: checks if the amount of traffic exceeds a specified value 3. binding a traffic rate policy: sys.check_limit(<limit_identifier>)
Answer D: https://docs.citrix.com/en-us/citrix-adc/current-release/appexpert/rate-limiting/configuring-binding-traffic-rate-policy1.html "The policy expression must be a compound expression that contains at least two components: - An expression that identifies traffic to which the rate limit identifier is applied http.req.url.contains("my_aspx.aspx"). - An expression that identifies a rate limit identifier sys.check_limit(“my_limit_identifier”)
The command combines two policy expressions to achieve the desired rate-limiting behavior. Here's a breakdown of the command components: SYS.CHECK.LIMIT(<limit_identifier>): This expression is used to define a system-level limit based on the specified limit identifier. It sets a limit on the overall system resources that can be consumed by the policy. HTTP.REQ.LIMIT(<limit_identifier>): This expression is used to set a limit on the rate of HTTP requests, in this case, DNS requests. The <limit_identifier> is a placeholder that should be replaced with an appropriate identifier specific to the policy. By combining these expressions using the "||" operator, the policy is configured to apply the rate limit based on both the system-level limit and the rate of DNS requests.
