QUESTION 89
Scenario: The network administrator at a company has HTTP-Inline and TCP-ECV monitors bound to services that send traffic to all production servers. A critical application component on these servers must be ugraded soon. A group of administrators will be working to upgrade this component as quickly as possible. The upgrade group has guaranteed that 60% of the production servers will be up at any time but has not guaranteed that any one server will be up at a given time. During the upgrade period, the network administrator wants the services bound to a server to be marked as DOWN in the NetScaler system the first time the response timeout is reached. The network administrator also wants the probe time to reflect the average time it takes to restart one of the production servers.

A.    Interval
B.    Retries
C.    Down Time
D.    Response Timeout
