Riverbed 830-01 Online Questions & Answers

• Question 231:

  While looking at the Current Connections page on a client-side Steelhead, you noticed that there is more CIFS traffic on the WAN than on the LAN for some connections. What may be the problem? 1) The source data is compressed or encrypted 2) File server not located on the same subnet as the server-side Steelhead 3) The Steelhead is counting both CIFS optimized and unoptimized traffic 4) CIFS read-ahead 5) CIFS write-behind

• Question 232:

  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. Remote appliances are registered when a fixed-target rule is applied to the appliance directing it to the CMC appliance
  C. Remote appliances are registered by proxy via the server-side Steelhead appliance
  D. Remote appliances are registered manually when they have not auto-registered with the CMC appliance
  E. Local appliances can only be registered manually, since fixed-target rules may only be applied to remote Steelhead appliances
  D. Remote appliances are registered manually when they have not auto-registered with the CMC appliance

• Question 234:

  When using GRE tunneling, you notice an application stops working and you know the application marks packets with the DF (Don't Fragment) flag. What is the cause of this?

  A. You cannot perform GRE encapsulation on packets which have the DF flag set.
  B. The additional 24-byte overhead used by GRE encapsulation has pushed the packets over the MTU size.
  C. GRE encapsulation has hidden the original IP header so the DF flag is no longer seen by the router and therefore it cannot forward the packet.
  D. Having the DF flag set results in the Steelhead being unable to use the TCP flow to monitor the path state, and the path selection rules is set to `drop' if the path is down.
  B. The additional 24-byte overhead used by GRE encapsulation has pushed the packets over the MTU size.

• Question 235:

  4) Hybrid Mode

  5) Proxy File Services (PFS)

• Question 236:

  Company X has many offshore oil rigs they want to bring optimization to. The only available connection is through a satellite that has frequent bursts of packet loss. There are very few users per rig and HTTPS-based SharePoint performance is so poor they often time out pulling down even a small file. CIFS often does not work at all. They are considering the Steelhead Mobile solution to solve this problem. You suggest they deploy a Steelhead in-path at the data center and:

  A. Steelhead Mobile with FEC turned on to help with lossy links
  B. Steelhead Mobile with HS-TCP configuration
  C. Steelhead Mobile running MX-TCP to deal with the loss
  D. Deploy Steelhead appliances with MX-TCP to deal with the loss
  E. Deploy Steelhead appliances with HS-TCP, Window Scaling, fixed-target rules, and TCP New Reno to overcome the loss
  D. Deploy Steelhead appliances with MX-TCP to deal with the loss

• Question 237:

  On the Steelhead Mobile Controller, what VPNs require the use of Reorder Intermediate Drivers? (Select 2)

  A. Nortel VPN
  B. Cisco VPN client
  C. Check Point
  D. OpenVPN
  E. Riverbed VPN client
  A. Nortel VPN
  C. Check Point

• Question 238:

  If a Steelhead appliance is configured for logical in-path mode:

  A. The Primary interface cannot be on the same subnet
  B. The LAN In-path interface will be disabled
  C. The WAN In-path interface will be disabled
  D. The Steelhead appliance listens for the Interceptor on TCP port 7860
  B. The LAN In-path interface will be disabled

• Question 239:

  Which of the following are configurable attributes of an Interceptor appliance? (Select 3)

  A. Synchronizing datastore
  B. Sharing connection state with a parallel Interceptor appliance
  C. Redirect to a Steelhead appliance cluster
  D. Failover to another Interceptor appliance
  B. Sharing connection state with a parallel Interceptor appliance
  C. Redirect to a Steelhead appliance cluster
  D. Failover to another Interceptor appliance

• Question 240:

  If the VPN concentrator that a Steelhead Mobile client connects to is not in path with a Steelhead appliance, what changes could be made to the Riverbed infrastructure to allow optimization from the Steelhead Mobile clients?

  A. Enable out-of-path support on server-side Steelhead
  B. Add a fixed-target rule in the Steelhead Mobile Acceleration policy
  C. Enable peering rule in Steelhead Mobile client
