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

  2. Option-78
  3. SACK
  4. WSCALE
  5. None of the above

Answer(s): E



If using Fixed-target rules, what Steelhead specific probe options are associated with the SYN packet?

  1. Option-76 (0x4c)
  2. Option-78 (0x4e)
  3. Client-side Steelhead's in-path IP address
  4. Client-side Steelhead's port number

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?

  1. The load balancing algorithm on the router is broken
  2. Simplified routing is not enabled
  3. Steelhead-B and Steelhead-C are missing the “in-path neighbor continue-intercept” command
  4. Steelhead-D is missing the “in-path neighbor allow-failure” command
  5. Need to issue the command “in-path accept connections” on Steelhead-D

Answer(s): D
