• Question 6:

  A SteelHead is running RiOS v8.6 and has an inpath0_0 IP address of 192.168.1.10. It is later upgraded from v8.6 to v9.0. As part of an IT project, the inpath0_0 IP address is changed to 10.10.10.10 and the configuration saved. Some time passes and the administrator decides to revert to RiOS v 8.6. It hasn't been factory reset. The appliance boots and the Management Console User Interface is reachable, however, optimization no longer works. What has happened?

  A. The web GUI SSL certificate is no longer trusted and the services require a restart.

  B. The licenses are no longer valid and will need to be replaced and the services restarted.

  C. It is not possible to revert to older versions of RiOS and the optimization service has stopped as a precaution.

  D. The configuration has reverted to the one running under v8.6 and the inpath0_0 IP address is back to

  192.168.1.10.

  E. The configuration has been lost and the appliance is running factory default settings.

  Correct Answer: D

• Question 7:

  You plan to downgrade a SteelHead from RiOS v9.0.1 (Apr 17 2015) to 8.6.3 (Aug 7 2015). The appliance has not run v8.6.3 previously. Will this be successful?

  A. No, downgrades are only permitted if the target version was previously installed.

  B. No, it is not possible to downgrade RiOS.

  C. Yes, the configuration will be migrated successfully during any downgrade.

  D. Yes, v8.6.3 is a chronologically newer version.

  Correct Answer: A

• Question 8:

  The SteelHead REST API connectivity can be used for which of the following?

  A. To synchronize layer 7 signatures and QoS configurations with the NetProfiler.

  B. To export QoS and other statistics to the SteelCentral Controller for SteelHead (SCC).

  C. To push secure transport configuration from the SCC to the SteelHeads NetProfiler.

  D. To push topology information to the SteelHeads from the SCC for path selection.

  E. To synchronize layer 7 signatures with the NetShark devices.

  Correct Answer: B

• Question 9:

  A SteelHead is deployed in a VLAN bridge. Which VLAN ID should be configured on the in-path interface to support this environment?

  

  A. 1

  B. 100

  C. 200

  D. No configuration is necessary as LAN and WAN interfaces are on access ports

  E. It will require an in-path interface for each VLAN

  Correct Answer: C

• Question 10:

  (host and host ) or (host and host ) or (proto gre

  and ((ip[40:4] =

  and

  ip[44:4] = ) or (ip[40:4] = and ip[44:4] = )) or (port 7850)

  What part of the filter captures the traffic which the Interceptor has applied NAT to?

  A. (ip[40:4] = and ip[44:4] = )

  B. (host and host )

  C. (proto gre and ((ip[40:4] = and ip[44:4] = )

  D. (host and host )

  Correct Answer: A
