Three additional parameters that are commonly specified when configuring the IP SLA ICMP echo operation are the timeout, frequency and threshold. Which of the following statements are FALSE about these parameters? Select THREE answers. The threshold commonly used in advanced IP SLA implementations The default timeout value varies depending on the type of IP SLAs operation you are configuring The threshold is specified in seconds and is used to specify the rate at which a specified Cisco IOS IP SLAs operation is sent into the network.

This value is specified in milliseconds and defaults to 5000 ms. The frequency is used to set the rising threshold used to generate a reaction event and stores the history information for the Cisco IOS IP SLA operation.
