Questions 102

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

830-01 Question 102

Options:
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

Questions 103

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:
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.

Questions 104

A SteelHead blocks all traffic when the appliance is powered off. What reasons could cause this behavior? (Choose two.)

Options:
A.

This behavior is by design.

B.

Router, switch and SteelHead interfaces have auto MDI/MDIX but incorrect cables have been used.

C.

Fail-to-block is enabled.

D.

The bypass NIC battery has failed.

E.

Router, switch and SteelHead interfaces are hard coded and incorrect cables have been used.

Questions 105

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?

Options:
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.

Questions 106

You have a pair of SteelHead appliances, both deployed in-path, both have a valid IP address on the in-path interfaces, optimizations are enabled and the service is started. They are unable to auto discover each other as a firewall is stripping the probes. How could you work around this on the SteelHeads?

Options:
A.

Enable Enhanced Auto Discovery on each SteelHead and restart the optimization service.

B.

Create a full transparency in-path rule on each SteelHead.

C.

Use static NAT entries for each in-path interface.

D.

Create a fixed-target in-path rule on each SteelHead pointing to the peer in-path IP address on port 7810.

E.

Create a port transparency in-path rule on each SteelHead

Questions 107

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?

Options:
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.

Questions 108

A user downloads a Microsoft Excel document from a server over an optimized connection. The transfer is very fast. The user makes some changes to the spreadsheet and then saves the document. The transfer is very slow. The user edited a Word document shortly before but that downloaded and saved at the same fast speeds. What happened to the Excel document?

Options:
A.

Microsoft Excel compresses and encrypts the data by default when saving Microsoft Excel data does not perform well for LZ compression and will always be slow.

B.

Microsoft Excel compresses the data by default when saving.

C.

Microsoft Excel reorders the entire data stream when it saves so it is now new (cold) data to the SteelHead.

D.

Microsoft Excel encrypts data by default when saving.

Questions 109

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:
A.

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

B.

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

C.

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

D.

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

E.

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