質問 1：
You have an existing Steelhead appliance deployment which is achieving excellent optimization at five sites.
You have deployed a Steelhead appliance physically in-path at a new small branch office and many of the new branch office users' applications are unoptimized; however some of the new branch office users' access to the same applications are optimized. None of the Steelhead appliances are in admission control. What is the likely cause?
A. WAN link disconnection
B. Overloaded servers
C. Duplex mismatch between the new branch office Steelhead and a connected device
D. Network Asymmetry
E. Duplex mismatch between the data center Steelhead and a connected device
正解：D

質問 2：
You are configuring HighSpeed TCP in an environment with an OC-3 (155Mb/s) and 60 milliseconds of round-trip latency. You know that the rule of thumb is to set the WAN router queue length to BDP for the link.

C. 3,110 packets
D. 6,220 packets
E. 10,000 packets
正解：B

質問 3：
Regarding the registering of Steelhead appliances,
A. Local appliances (on the same IP subnet) are automatically registered every time because their 10-byte probe is intercepted by the CMC appliance
B. Local appliances can only be registered manually, since fixed-target rules may only be applied to remote Steelhead appliances
C. Remote appliances are registered when a fixed-target rule is applied to the appliance directing it to the CMC appliance
D. Remote appliances are registered by proxy via the server-side Steelhead appliance
E. Remote appliances are registered manually when they have not auto-registered with the CMC appliance
正解：E
