You wish to utilize a SteelHead to fill a high bandwidth, high latency WAN link without data reduction. The link is 622mbps and 500ms latency. What steps should you take to fill the pipe?

A.

Enable HSTCP, configure the WAN buffers and enable SDR/LZ.

B.

Enable HSTCP, configure the WAN buffers and disable SDR/LZ.

C.

Max-TCP and HS-TCP are only for optimized flows, so data reduction cannot be disabled but will fill the pipe anyway.

D.

Enable MXTCP, configure the WAN buffers and disable SDR/LZ.

E.

Enable MXTCP, configure the WAN buffers and enable SDR/LZ.

In a virtual-inpath deployment, when the Steelhead appliance exports data to a flow data collector:

A.

All traffic has the LAN and WAN interface index.

B.

All traffic has the WAN interface index.

C.

All traffic has the LAN interface index.

D.

All traffic has the primary interface index.

What type of problem does the error message below indicate:

Sep 7 22:53:50 SH pm[18184]: [pm.NOTICE]: Output from sport:

/opt/rbt/bin/sport (pid 27529) received signal 12 (SIGUSR2) marking bit

A.

It is not a problem. The message is displayed when a system dump is generated.

B.

The management process crashed

C.

The optimization process crashed

D.

The management process received permission to apply QoS marking

E.

The sport process received permission to apply QoS marking

A parallel SteelHead deployment between datacenters is being discussed by a customer and an Integrator. The customer would like to configure connection forwarding between the SteelHeads in two datacenters with 20 ms RTT between them. What would be the possible outcome, if the nearest branch SteelHead is 40 ms away?

A.

The latency between the Neighbor SteelHeads will mean that Connection Forwarding will not come up.

B.

All asymmetrically routed traffic will suffer from increased latency from the nearer branches.

C.

The Nagle algorithm timer can be adjusted so as to mitigate the symptoms from the closer branches.

D.

There will be little or no impact as it only affects the initial connection.

E.

Suboptimal performance only from HTTP traffic due to increased connection times.

In a WCCP environment with R3, SH10 and SH11, it was observed that SH11's WCCP state is "read error". What is the possible cause?

A.

The Steelhead is not receiving i-see-you messages from the router

B.

The Steelhead is not sending here-i-am messages to the router

C.

The Steelhead is not receiving removal query messages from the router

D.

Everything is in order – working properly

SteelHead SaaS is configured using the default redirection port. Which statement correctly describes the configuration that must be applied to a firewall at the branch location?

A.

Allow UDP 9545 from/to In-path interfaces

B.

Allow 443 traffic from/to Primary interface

C.

Allow TCP 9545 from/to In-path interfaces

D.

Allow TCP 9545 from/to Primary interfaces

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.

The SteelHead Out of Band splice (OOB) uses which addressing mode? Assume a default configuration.

A.

Always correct addressing.

B.

Depends on which addressing mode the first optimized connection uses.

C.

Always transparent addressing.

D.

Always destination transparency.

You plan to downgrade a SteelHead from RiOS v9.0.1 (Apr 17 2015) to 8.6.3 (Aug 7 2015). The appliance was previously running v8.6.3 but was factory reset after the upgrade. Will this be successful?

A.

No, there is no longer a configuration file for v8.6.3

B.

Yes, the current v9.0.1 configuration file will be migrated

C.

Yes, the old configuration file from v8.6.3 will be loaded

D.

No, it is not possible to downgrade RiOS

You are troubleshooting a TCP connection that is not being optimized. On the Current Connections report, you expand the connection and see the pass-through reason is ‘Pre-existing connection’. Without restarting the oprimization service, how could you get this connection to optimize?

A.

Reset the connection in the Current Connections report.

B.

Create a full-transparency in-path rule for the source and destination hosts.

C.

Create a fixed-target in-path rule for the source and destination hosts.

D.

Enable auto-kick-off on the default in-path rule.

E.

Enable Simplified Routing in ‘all’ mode.
