• Question 233:

  Refer to the exhibit.

  

  A user from one of your branch offices reports connections to servers are failing after a new deployment. The exhibit shows how the Steelhead appliances have been deployed. Which of the following will most likely fix the issue? (Select 2)

  A. Fixed-target rule is needed on the client-side Steelhead appliance

  B. Change the WCCP to use Redirect Out instead of Redirect In

  C. Remove Redirect-IN from the LAN at the Branch Office

  D. Add Redirect-IN on the WAN at the HQ

  E. Remove fixed-target rule from the server-side Steelhead appliance

  Correct Answer: AD

• Question 234:

  The exhibit shows a data center side serial clustering deployment. In this organization, not every remote site has a Steelhead appliance deployed, and all remote locations will be connecting to the data center.

  

  For connections initiated from the data center, there is a possibility that the Steelhead appliances shown in the exhibit will end up peering with each other, rather than the intended remote Steelhead appliances.

  Where are peering rules needed to prevent this problem?

  A. A only

  B. B only

  C. B and C

  D. A and B

  Correct Answer: D

• Question 235:

  Refer to the exhibit.

  

  A customer has a server-side out-of-path deployment, and reports that connections from some of their remote branch offices are not being optimized. What is the most likely problem?

  A. A missing fixed-target rule on the server-side Steelhead appliance

  B. A missing fixed-target rule on the client-side Steelhead appliance

  C. The WAN interface is connected to the server-side Steelhead appliance

  D. The LAN interface is connected to the server-side Steelhead appliance

  E. Using port 7810 in the fixed-target rule instead of 7800

  Correct Answer: B

• Question 236:

  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

  Correct Answer: A

• Question 237:

  A Windows Vista client tries to download a file from a Windows 2008 server over a 45Mbps link with 200ms. Assuming the connection is optimized, given the default configuration on the Steelhead, what optimization techniques would be applied? 1) Data Streamlining 2) Transport Streamlining 3) MS-SQL Transaction Prediction 4) HighSpeed TCP 5) MX-TCP

  A. 1, 2, 3

  B. 1, 2

  C. 1, 2, 3, 4

  D. 1, 2, 3, 5

  E. 1, 3, 4

  Correct Answer: B

• Question 238:

  Refer to the exhibit.

  

  You configured CIFS prepopulation at Corp-A but it is not working. What is likely the cause of the issue?

  A. CIFS prepopulation requires WCCP

  B. Primary interface needs to be on a different subnet

  C. CIFS prepopulation requires a fixed-target rule

  D. The Primary interface needs to be on the LAN side of the Steelhead appliance

  E. CIFS prepopulation requires SMBv2

  Correct Answer: D

• Question 239:

  Refer to the exhibit.

  

  You noticed the following entry in the logs. What is the cause of the problem?

  A. Complete asymmetry

  B. Server-side asymmetry

  D. Multi-syn retransmit

  E. SYN retransmit

  Correct Answer: C

• Question 240:

  Refer to the exhibit.

  

  Corp-A and Corp-B have overlapping address space and therefore the network administrator implemented NAT to overcome this. Users from Corp-A NAT to 172.16.1.0/24 and users from Corp-B NAT to 172.16.2.0/24. Users in Corp-A use the destination address of 172.16.2.0/24 to access the resources in Corp-B. The servers in Corp-B use the client IP for authentication. What do you need to do in order to make this deployment work? (Select 2)

  A. Configure Full Transparency

  B. Configure out-of-path

  C. Configure Port Transparency

  D. Configure OOB Transparency

  E. Steelhead appliances cannot be deployed in this network

  Correct Answer: AD
