You wish to optimize SSL connections to an internal server. Where should the server certificate and private key be installed?

A.

Client-side and server-side SteelHead Certificate Authority list

B.

Server-side SteelHead SSL server certificate list

C.

Client-side SteelHead and server-side SteelHead SSl server certificate list

D.

Client-side SteelHead SSL Server certificate list

A recently installed branch SteelHead is successfully optimizing connections inbound from other locations. However, users report that their connections originating from that branch don’t seem to be any faster and the Current Connections report shows their connections to be in pass-through. In-path rules correctly specify that auto-discovery should occur. What might be the problem?

A.

Simplified Routing should be enabled.

B.

There is asymmetry in the network.

C.

The optimization service on the branch SteelHead is not running.

D.

There is a duplex mismatch on the LAN port.

E.

The SteelHead LAN and WAN ports have been wired in reverse.

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The licenses are no longer valid and will need to be replaced and the services restarted.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

What configuration policies can be used on the SteelCentral Controller for SteelHead (SCC) for Interceptor deployments?

A.

The SCC can be used to create all configuration for the Interceptors and its associated SteelHeads, as long as all the devices are in the same SCC group.

B.

The SCC can create in-path rules policies the same as a SteelHead, as long as that is the only page enabled for the Interceptor.

C.

The SCC can be used to configure the cluster of registered Interceptors and SteelHeads. Then, in-path rules and load balancing rules can be pushed to the interceptors.

D.

The SCC can be used to create cluster policies, for the Interceptor to SteelHead connections only and not in-path or load balancing rules.

E.

The SCC can only monitor the health, backup the configuration and upgrade Interceptors. Policies are only for SteelHeads. Interceptors and SteelHead Mobile are not supported.

When configuring encrypted Lotus Notes optimization and the standard port is configured to require encryption, which of the following is true?

A.

An alternate unencrypted port must be open on the server, and a copy of the server ID file must be imported to the server side SteelHead.

B.

An alternate unencrypted port must be open on the server, and a proxy server ID file must be created on the server-side SteelHead.

C.

An encrypted port must be open on the server, and a proxy server ID file must be created on the server-side SteelHead.

D.

An encrypted port must be open on the server, and a copy of the server ID file must be imported to the server-side SteelHead.

You are using TCPdumps on the server-side SteelHead to troubleshoot an application connectivity issue. The following filter is used on the TCPdump:

(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)

A.

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

B.

(host and host )

C.

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

does not capture packets with an 803.3Q tag.

D.

does not capture packets with an 802.11Q tag.

B.

He is collecting traffic using tcpdump on the Steelhead WAN interface
