B. B and C

C. A, B, and C

D. Enable Optimizations on Interface inpath0_0

E. Enable L4/PBR/WCCP Support on Interface wan0_0

Correct Answer: B

Question 2

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. Simplified routing is not enabled

B. Steelhead-D is missing the "in-path neighbor allow-failure" command

C. Steelhead-B and Steelhead-C are missing the "in-path neighbor continue-intercept" command

D. The load balancing algorithm on the router is broken

E. Need to issue the command "in-path accept connections" on Steelhead-D

Correct Answer: B

Question 3

When deploying a Virtual Steelhead appliance, how much extra memory should be allocated for the extra VMware overhead?

A. 4%

B. 10%

C. 2%

D. 5%

E. 3%

Correct Answer: D

Question 4

In a recent in-path deployment, users are complaining that some of their CIFS drive-mapping connections do not appear to be optimized. Upon further analysis, you discover the file shares reside on a domain controller.
The Steelhead appliances are deployed in a default configuration. Which of the following is the most likely cause of the problem?

A. SMB Signing is set to required

B. Misconfigured Steelhead appliance

C. The Steelhead appliance lost an Opportunistic Lock on the file

D. Packet ricochet

E. No fixed-target rules installed

Correct Answer: A

Question 5

Why should you use promiscuous mode on each in-path virtual NIC for Virtual Steelhead appliance? (Select
2)

A. Promiscuous mode is not required

B. Only verbose mode should be configured

C. This configuration is mandatory for traffic optimization

D. Only regular mode should be configured

E. For LAN/WAN Virtual NICs to intercept traffic not destined for the virtual machine

Correct Answer: C,E

Question 6

What is the command to return a Steelhead appliance back to factory defaults?

A. (config) # reload factory

B. (config) # restart factory reload

C. (config) # reload clean empty

D. (config) # reset factory reload

E. (config) # restart clean

Correct Answer: D

Question 7

You have a number of SteelHeads running RiOS 9.x. At each datacenter site, there are a cluster of domain controllers, one of which the SteelHead is connected to. As the volume of users on the network increase, the load which the server-side SteelHeads are placing on the connected domain controller pushes the domain to its limits, and authentication failures sometimes occur. What is the best way to address this?

A. Disable Kerberos authentication on the SteelHeads so as to down negotiate to NTLM, specifying multiple domain controllers during the domain-join.

B. Increase the time Kerberos tickets are cached for individual users on the SteelHeads.

C. Configure domain controller load-balancing so the SteelHead can communicate with multiple domain controllers instead of just one.

D. Identify traffic which does not have a high rate of data reduction, and use in-path rules to path this traffic through.

Correct Answer: C

Question 8

What should you do when you receive the following message?

A. Switch off the Steelhead appliance

B. Reload the Steelhead appliance

C. Nothing. This is a warning message which means that the Steelhead appliance is resetting an internal state regarding this connection and it should not affect user performance.

D. Create a specific pass-through rule to bypass the above source and destination hosts

Correct Answer: C
