Riverbed 199-01 Online Questions & Answers

• Question 31:

  You are troubleshooting a new Steelhead Mobile installation where none of the VPN users with Steelhead Mobile client installed are being optimized. You determine that the Steelhead appliance in the data center is not in-path for VPN users. What are your options to fix this? (Select 2)

  A. Use the Steelhead in an out-of-path deployment using fixed-target rules in the Steelhead appliance
  B. Use the Steelhead in a hybrid in-path/out-of-path deployment using fixed-target rules in the Steelhead Mobile client
  C. Put the Steelhead appliance in-path on the VPN concentrator segment using a multi-port NIC
  D. Install the Steelhead Mobile Controller on the VPN segment
  B. Use the Steelhead in a hybrid in-path/out-of-path deployment using fixed-target rules in the Steelhead Mobile client
  C. Put the Steelhead appliance in-path on the VPN concentrator segment using a multi-port NIC

• Question 32:

  You enabled port transparency but noticed that active FTP connections are failing. What may be the problem?

  A. The routers need to understand port transparency
  B. Port transparency only maintains destination ports
  C. Port transparency requires NAT
  D. You need to a fixed-target rule on the server-side for port transparency
  E. None of the above
  B. Port transparency only maintains destination ports

• Question 33:

  Refer to the exhibit.

  

  What option in the Acceleration policy used on Steelhead Mobile Client A will most likely enhance the users experience connecting to Server B, if Server B is an Exchange 2003 Server?

  A. Enable MAPI NSPI
  B. Increase the datastore size
  C. Enable latency-based location awareness
  D. Enable SSL optimization and import the Exchange certificate for Server B into Steelhead B
  E. Peering rule rejecting optimization with Steelhead A
  C. Enable latency-based location awareness

• Question 34:

  After a new physical in-path installation, all applications appear to be slower. Adding a pass-through rule does not seem to fix the problem. Which of the following is the most likely cause of the problem?

  A. Duplex mismatch
  B. Firewall blocking auto-discovery probes
  C. No fixed-target rules installed D. A and C
  E. A, B, and C
  A. Duplex mismatch

• Question 35:

  Refer to the exhibit.

  

  If Steelhead Mobile Client B offers up a share on the network, what is needed on Steelhead Mobile Client R to open an optimized connection to this share if enhanced auto-discovery is enabled on all Steelhead appliances?

  A. Default auto-discovery will work fine without modification
  B. The connection to Client B cannot be optimized because the Steelhead Mobile Controller cannot optimize incoming connections
  C. A fixed-target rule to Client B's IP address is needed in order for optimization to occur on Mobile Client B
  D. The addition of a peering rule
  A. Default auto-discovery will work fine without modification

• Question 36:

  A firewall at a remote site on the WAN side of Steelhead appliance (A) is stripping out the 76 and 78 values in the TCP options field. Steelhead appliance (B) is in the local cluster of appliances communicating with an Interceptor appliance. The desired result is for optimization to continue between Steelhead appliance (A) and Steelhead appliance (B) for all traffic originating from the remote site. A suggestion is made to use fixed target rule(s) to meet this objective. Based on the information provided select the best answer from the choices below:

  A. On Steelhead appliance (A) configure a fixed-target rule to the Interceptor in-path address
  B. On Steelhead appliance (A) configure a fixed target rule to the Interceptor in-path address with Steelhead appliance (B) as the backup target.
  C. On Steelhead appliance (A) configure a fixed target rule to the Steelhead appliance (B) in-path address
  D. Fixed target rules will not work with Steelhead appliances virtually out of path and communicating with Interceptors
  E. TCP option 76 or 78 are not relevant when an Interceptor appliance is used, Peer Affinity will automatically achieve this objective
  C. On Steelhead appliance (A) configure a fixed target rule to the Steelhead appliance (B) in-path address

• Question 37:

  Which of the following are Steelhead Mobile Controller alarms? (Select 2)

  A. Memory paging
  B. Datastore errors
  C. Peer version mismatch
  D. SSL errors
  E. File system full
  A. Memory paging
  E. File system full

• Question 38:

  What are an Interceptor appliance's main functions? (Select 2)

  A. Provides a way to intercept and redirect interesting traffic for optimization
  B. Monitors multiple links and redirect interesting traffic over a cluster of Steelhead appliances in a logical in-path deployment
  C. Replaces any existing Layer 4 switch in a given environment
  D. Used to configure and work with WCCP and PBR
  E. Required component Steelhead appliances in all Steelhead appliance deployments
  A. Provides a way to intercept and redirect interesting traffic for optimization
  B. Monitors multiple links and redirect interesting traffic over a cluster of Steelhead appliances in a logical in-path deployment

• Question 39:

  Given four Steelheads are deployed in a WCCP cluster and all Steelheads are optimizing traffic to and from the data center. Steelhead-A fails and only Steelhead-B and Steelhead-C are intercepting new connections while Steelhead-D is NOT optimizing any traffic. What is the likely problem?

  A. The load balancing algorithm on the router is broken
  B. Simplified routing is not enabled
  C. Steelhead-B and Steelhead-C are missing the "in-path neighbor continue-intercept" command
  D. Steelhead-D is missing the "in-path neighbor allow-failure" command
  E. Need to issue the command "in-path accept connections" on Steelhead-D
  D. Steelhead-D is missing the "in-path neighbor allow-failure" command

• Question 40:

  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.
