Questions # 31:

When optimizing applications that open many short-lived HTTP connections, which operating mode will give the best performance?

Options:

Full Transparency

Full Transparency with reset

Correct Addressing

Port Transparency

Any of the above, because performance is not affected by these

Expert Solution

Questions # 32:

A customer would like to optimize an in-house application running over UDP. What is required in order to do this? (Choose two.)

Options:

Packet-mode optimization enabled in the General Service Settings.

Auto-Discover UDP rules correctly configured on the client-side SteelHead.

Fixed target rules correctly configured on the client-side and server-side SteelHeads.

An UDP license purchased and installed on all SteelHeads.

Only TCP is supported for optimization on SteelHead appliances.

Questions # 33:

While performing a health check for a Steelhead appliance at a remote site, you noticed some of the pass-through traffic should have been optimized. The pass-through reason for the suspicious traffic is "SYN on WAN side". Upon further investigating, you also noticed that all of the traffic initiated at the data center is pass-through while all of the traffic initiated at the remote site is optimized. There is only one path between the data center and the remote site and both Steelhead appliance are physically in-path. What are the possible causes? (Select 2)

Options:

There is a pass-through in-path rule configured on the data center Steelhead appliance.

There is a pass-through in-path rule configured on the remote site Steelhead appliance.

There is a pass-through peering rule configured on the data center Steelhead appliance.

The LAN and WAN interfaces on the data center Steelhead appliance are reversed.

The LAN and WAN interfaces on the remote site Steelhead appliance are reversed.

Questions # 34:

You would like to upgrade a Virtual SteelHead VCX755-L to VCX755-H. What is required to permit the upgrade to succeed? (Choose three.)

Options:

Additional bypass cards

Additional CPU(s)

An upgrade license key

Additional Storage capacity for data store

Additional Memory

Questions # 35:

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?

Options:

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

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

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

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

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

Question # 36

-- Exhibit --

Refer to the exhibit. A Steelhead administrator has recently decided to implement two Interceptor appliances and one Steelhead appliance on his data center. After configuring the Interceptor, he noticed they are not forwarding traffic to the Steelhead. Why? (Select 2)

Options:

The Steelhead appliance was not added into the Interceptor appliance configuration.

The Interceptor appliance was not added into the Steelhead appliance "add an IC" option on the Steelhead appliance config.

The Interceptor appliance was not added as a connection forwarding neighbor on the Steelhead appliance.

The Steelhead appliance is down.

Refer to the exhibit. On the Current Connections report, what does the number under "WAN KB" represent?

Options:

Segments

Datagrams

References

Packets

Expert Solution

Questions # 38:

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

Options:

To keep similarly sized SteelHead models peering with each other.

To ensure load is distributed evenly throughout the cluster.

To maximize the benefits of SDR by maintaining SteelHead peering relationships.

To ensure asymmetrically routed connections are optimized.

To make sure cluster SteelHeads remain connected to the same Interceptor.

Expert Solution

Questions # 39:

Consider a SteelHead deployment with SMB optimization and SMB signing enabled on all SteelHeads. The client is configured to have signing enabled and the server has signing disabled. What will happen to SMB connections between these two hosts?

Options:

The connection will be unsigned but allowed. The SteelHead does not need to have SMB signing enabled to accommodate this connection.

The connection will not be allowed, as signing is enabled on the client and disabled on the server.

The connection will be allowed and will be signed as the client determines whether SMB signing is used or not.

The connection will be allowed, and will be signed between the client and client-side SteelHead.

Expert Solution

Questions # 40:

You have a SteelCentral Controller for SteelHead Mobile with a policy that includes auto-discovery rules, enabled Location Awareness and set a minimum latency of 10ms. Your client is now in the branch office, has received this policy and the nearest SteelHead is 2 ms away. What will happen to connections?

Options:

The branch steelhead will pass through the traffic because of the RVBD in-path rule.

The SteelHead Mobile client will bypass the branch SteelHead using Enhanced Auto Discovery.

The SteelHead Mobile client will not optimize, letting the branch SteelHead do the optimization.

The branch SteelHead will shut-down the SteelHead mobile client services as they are not needed in branch.

The SteelHead Mobile client will optimize as normal, sharing information with the branch SteelHead.
