Riverbed 830-01 practice test

RCPE Certified Professional WAN Optimization Exam

Question 1

The SteelHead Out of Band splice (OOB) uses which addressing mode? Assume a default
A. Always correct addressing.
B. Depends on which addressing mode the first optimized connection uses.
C. Always transparent addressing.
D. Always destination transparency.




Question 2

What is the purpose of ‘Peer Affinity’ on the Interceptor?

  • A. To keep similarly sized SteelHead models peering with each other.
  • B. To ensure load is distributed evenly throughout the cluster.
  • C. To maximize the benefits of SDR by maintaining SteelHead peering relationships.
  • D. To ensure asymmetrically routed connections are optimized.
  • E. To make sure cluster SteelHeads remain connected to the same Interceptor.



Question 3

What is the first step in optimizing an SMTPS session?

  • A. An unencrypted SMTP connection is intercepted and optimized, before a START-TLS is issued.
  • B. START-TLS is issued immediately by the client and intercepted by the client side SteelHead.
  • C. SteelHeads do not currently support optimizing SMTPS sessions.
  • D. An SSL client HELLO is sent by the client and intercepted by the client side SteelHead.



Question 4

A SteelHead is running RiOS v8.6 and has an inpath0_0 IP address of It is later
upgraded from v8.6 to v9.0. As part of an IT project, the inpath0_0 IP address is changed to and the configuration saved. Some time passes and the administrator decides to revert
to RiOS v 8.6. It hasnt 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  • B. The licenses are no longer valid and will need to be replaced and the services restarted.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
  • E. The configuration has been lost and the appliance is running factory default settings. 156/157 Questions & Answers PDF P-



Question 5

Which deployment options are available to Virtual SteelHead on ESXi?

  • A. Physical In-path (with Riverbed bypass NIC)
  • B. Virtual In-path
  • C. Out-of-path
  • D. Server-side Out-of-Path
  • E. All of the above



Question 6

A customer uses a single URL for a service that uses many servers with different certificates. What
SSL options should be enabled to enhance performance?

  • A. Passive key derivation
  • B. SSL proxy support and SNI (Server name indication)
  • C. SSL advanced mode
  • D. Early start/late finish



Question 7

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). 155/157 Questions & Answers PDF P-
  • 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.



Question 8

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.



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?
Questions & Answers PDF

  • 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



Question 10

You are using TCPdumps on the server-side SteelHead to troubleshoot an application connectivity
issue. The following filter is used on the TCPdump:
(host <client IP> and host <server IP>) or (host <server IP> and host <steelheadinpath IP>) or (proto
gre and ((ip[40:4] = <hex server IP>
ip[44:4] = <hex client IP>) or (ip[40:4] = <hex client IP> and ip[44:4] = <hex server IP>)) or (port 7850)
What part of the filter captures the traffic which the Interceptor has applied NAT to?

  • A. (ip[40:4] = <hex client IP> and ip[44:4] = <hex server IP>)
  • B. (host <server IP> and host <steelhead inpath IP>)
  • C. (proto gre and ((ip[40:4] = <hex server IP> and ip[44:4] = <hex client IP>)
  • D. (host <client IP> and host <server IP>)
