Riverbed Riverbed Certifications 830-01 Questions & Answers

• Question 131:

  In a Steelhead deployment, the customer decides to use Full Transparency and block all incoming/ outgoing TCP connections on port 7800 on their firewall. However, they are finding all TCP connections are passing through the Steelheads (even ones that should be optimized via the in-path rule set). If Full Transparency uses the original IP addresses and TCP ports for inner connections, what is needed to fix the problem?

  A. "no in-path enable"; since we don't really need in-path in this case

  B. "destination oobtransparency"; since the OOB (out-of-band) splice needs transparency also

  C. "inner connection max 50"; since the default inner connection pool count of 20 is insufficient

  D. No command needed, the connections are really optimized even though we report connections are passed through

  Correct Answer: B

• Question 132:

  A single client-server TCP connection is made through two Steelhead appliances (default in-path deployment). This is a lab-controlled environment and no other client-server connections are made. How many TCP connections will exist between the in-path interfaces of both Steelhead appliances after the user connection is fully established?

  A. 1

  B. 20

  C. 22

  D. 42

  Correct Answer: C

• Question 133:

  In a Steelhead appliance deployment, the customer decides to use Full Transparency and block all incoming/outgoing TCP connections on port 7800 on their firewall. However, they are finding all TCP connections are passing through the Steelhead appliances (even ones that should be optimized via the in-path rule set). If Full Transparency uses the original IP addresses and TCP ports for inner connections, what is the most likely cause of all TCP connections passing through the Steelhead appliances?

  A. The OOB (out-of-band) splice connection cannot be made

  B. The user connections (if using the same ephemeral TCP port) are blocking each other, since the Steelhead appliance had to make all of these sequentially

  C. Full Transparency is only supported on Steelhead 3U appliances

  D. All connections are being blocked by the firewall

  Correct Answer: A

• Question 134:

  When using Correct Addressing, what is the out-of-band (OOB) splice connection described as?

  A. A virtual connection contained within one of the inner-connections which corresponds to a client- server connection

  B. A separate connection between the Primary IP addresses of the client and server Steelhead appliances

  C. A separate inner-connection between two Steelhead appliances not directly related to any one of the user inner connections

  D. No such construct exists

  Correct Answer: C

• Question 135:

  You are configuring HighSpeed TCP in an environment with an OC-3 (155Mb/s) and 60 milliseconds of round-trip latency. You know that the rule of thumb is to set the WAN router queue length to BDP for the link. Assuming 1500 byte packets, the queue length for this link would be closest to: (Hint: Use the calculator)

  A. 3,110 packets

  B. 6,220 packets

  C. 775 packets

  D. 150 packets

  E. 10,000 packets

  Correct Answer: C

• Question 136:

  Which command shows the last boot partition and the next boot partition? (Select 2)

  A. show bootvar

  B. show images

  C. show info

  D. show bootpar

  E. show system

  F. show version

  Correct Answer: AB

• Question 137:

  You are configuring HighSpeed TCP in an environment with an OC-3 (155Mb/s) and 60 milliseconds of round-trip latency. You know that the rule of thumb is to set the Steelhead appliance's WAN Default Send Buffer Size and WAN Default Receive Buffer Size to 2*BDP for the link. The buffer size setting for this link would be closest to: (Hint: Use the calculator)

  A. 4,665,000 bytes

  B. 9,330,000 bytes

  C. 3,110 bytes

  D. 6,220 bytes

  E. 2,325,000 bytes

  Correct Answer: E

• Question 138:

  What is the CLI command for starting the Configuration Wizard?

  A. # configuration wizard start

  B. (config) # configuration jump-start

  C. # configuration start

  D. (config) # wizard start

  E. restart clean

  Correct Answer: B

• Question 139:

  What steps take place during an upgrade process?

  A. The new software image will be loaded into the Backup partition; a reboot will be necessary to have the Steelhead appliance switch to the newer software

  B. The new software image will be loaded into the Booted partition; a reboot will be necessary to have the Steelhead appliance switch to the newer software

  C. The new software image will be loaded into the Backup partition; a restart will be necessary to have the Steelhead appliance switch to the newer software

  D. The new software image will be loaded into the Booted partition; a restart will be necessary to have the Steelhead appliance switch to the newer software

  E. The new software image will be loaded into the Backup partition; a configuration save will be necessary to have the Steelhead appliance switch to the newer software

  Correct Answer: A

• Question 140:

  What is the command to clear all statistics on a Steelhead appliance?

  A. (config) # stats clear-all

  B. (config) # clear-all stats

  C. (config) # reset stats

  D. (config) # reload stats clean

  E. (config) # clear stats

  Correct Answer: A
