NEW QUESTION 22
How should a BIG-IP Administrator control the amount of traffic that a newly enabled pool member receives.
- A. set a Health Monitor
- B. set the Slow Ramp Time
- C. set the Priority Group Activation
- D. set a Connection Limit
Answer: B
Explanation:
Explanation
Slow Ramp Time
Specifies the duration during which the system sends less traffic to a newly-enabled pool member. The amount of traffic is based on the ratio of how long the pool member has been available compared to the slow ramp time, in seconds. Once the pool member has been online for a time greater than the slow ramp time, the pool member receives a full proportion of the incoming traffic. Slow ramp time is particularly useful for the least connections load balancing mode.
Setting this to a nonzero value can cause unexpected Priority Group behavior, such as load balancing to a low-priority member even with enough high-priority servers.
