質問 # 85
How should a BIG-IP Administrator control the amount of traffic that a newly enabled pool member receives?
- A. set the Priority Group Activation
- B. set a Health Monitor
- C. set a Connection Limit
- D. set the Slow Ramp Time
正解：D
解説：
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.
質問 # 86
Refer to the exhibit. An LTM device is used to load balance web content over a secure channel.
The developers of the web content have done a trace using an HTTP profiler application. They believe that allowing the LTM device to compress traffic to the client will improve performance.
The client can utilize GZIP or deflate compression algorithms.
An LTM Specialist must implement the compression.
The LTM Specialist has completed the following actions:
1. Create the relevant profile.
2. Apply the relevant profile to the virtual server (VS).
After applying the relevant profile, the LTM device is failing to compress the traffic. Instead, the traffic is being served with an error.
What is the problem?
- A. The Protocol Profile (Server) option of "Allow Compression" needs to be enabled.
- B. The LTM device CANNOT SSL offload the traffic in order to read and compress it.
- C. The Protocol Profile (Client) option of "Allow Compression" needs to be enabled.
- D. The incorrect compression algorithm is applied to the compression profile.
正解：B
質問 # 87
