質問 9

A recently installed branch SteelHead is successfully optimizing connections inbound from other locations.
However, users report that their connections originating from that branch don't seem to be any faster and the Current Connections report shows their connections to be in pass-through. In-path rules correctly specify that auto-discovery should occur. What might be the problem?

（A）There is a duplex mismatch on the LAN port.

（B）There is asymmetry in the network.

（C）The optimization service on the branch SteelHead is not running.

（D）The SteelHead LAN and WAN ports have been wired in reverse.

（B）Place the Steelhead Mobile Controller in-path directly behind the VPN gateway and use auto-discovery on the Steelhead Mobile client

（C）Place a Steelhead appliance in-path behind the WAN router and have the Steelhead Mobile client use auto-discovery rules

（D）Place a Steelhead in-path directly behind the VPN gateway and use auto-discovery on the Steelhead Mobile client

質問 13

A customer already has a SteelHead appliance in their datacenter and wants to add Steelhead Mobile. Their current deployment has their VPN gateway in parallel with their server-side SteelHead. The customer doesn't want to interrupt VPN clients by moving the SteelHead in-path with the VPN gateway, so they will test using a fixed-target rule to the SteelHead in-path interface. Take a look at this diagram:

Will the client traffic be optimized to the server 192.168.1.10?

（A）No, the SteelHead Mobile client will report 'asymmetry' and fail to optimize.

（B）No, the fixed-target rule should be directed to the SteelCentral Controller for SteelHead Mobile IP address.

（C）Yes, the fixed-target rule will direct traffic to the SteelHead correctly.

（D）Yes, the WAN router will redirect traffic to the SteelHead using PBR.
