  Correct Answer: AB

• Question 122:

  The adaptive data streamlining settings are:

  A. Default , RiOS SDR- L, RiOS SDR-M

  B. Default , RiOS DSR- Adaptive, RiOS DSR-M

  C. Default , RiOS SDR- Adaptive, RiOS SDR-M

  D. Default , RiOS SDR- Adaptive, RiOS SDR-L

  E. RiOS SDR- Adaptive, RiOS SDR-L, RiOS DSR-M

  Correct Answer: C

• Question 123:

  Adaptive data streamlining provides you:

  A. with the ability to fine tune the data streamlining capabilities, and enables you to obtain the right balance between optimal bandwidth reduction and optimal throughput

  B. with the ability to fine tune the data streamlining capabilities, and enables you to obtain the right balance between optimal bandwidth reduction and optimal acceleration

  C. with the ability to fine tune the compression capabilities, and enables you to obtain the right balance between optimal bandwidth reduction and optimal throughput

  D. with the ability to fine tune the compression capabilities, and enables you to obtain the right balance between optimal bandwidth reduction and optimal acceleration

  Correct Answer: A

• Question 124:

  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 125:

  Which of the following commands followed by "write memory" will allow you to turn off in-path optimization but turn it back on upon rebooting the Steelhead appliance?

  A. no in-path enable

  B. restart clean

  C. reload

  D. no service enable

  E. no interface in-path0_0 enable

  Correct Answer: D

• Question 126:

  D. 389

  E. 49

  Correct Answer: C

  A. 4 bytes

  B. 10 bytes

  C. 14 bytes

  D. 18 bytes

  E. 32 bytes

  Correct Answer: C

• Question 128:

  C. 14 bytes

  D. 18 bytes

  E. 32 bytes

  Correct Answer: D

• Question 129:

  A. 4 bytes of notification

  B. 10 bytes of TCP inner channel setup + 2 bytes of notification

  C. 14 bytes of TCP inner channel setup + 4 bytes of notification

  D. 18 bytes of TCP inner channel setup + 4 bytes of notification

  E. 32 bytes of TCP inner channel setup + 2 bytes of notification

  Correct Answer: C

  A. 0x4e

  B. 0x4d

  C. 0x4c

  D. 0x4b

  E. No probe is used

  Correct Answer: A
