The Home page in the Management Console for the CMC appliance can be configured to display what information?

A. Default login used by the CMC appliance for each appliance

B. Last hour of throughput across all managed appliances

C. Status of each individual alarm for each managed Steelhead appliance

D. Last 20 lines of a Steelhead appliance's system log file

While looking at the Current Connections page on a client-side Steelhead, you noticed that there is more CIFS traffic on the WAN than on the LAN for some connections. What may be the problem? 1) The source data is compressed or encrypted 2) File server not located on the same subnet as the server-side Steelhead 3) The Steelhead is counting both CIFS optimized and unoptimized traffic 4) CIFS read-ahead 5) CIFS write-behind

A. 1, 4

B. 4, 5

C. 1, 2, 3

D. 1, 2, 5

E. 3, 5

Where in the Steelhead appliance can you verify IP address settings? (Select 2)

A. Interface Statistics

B. View the configuration

C. Neighbor Statistics

D. QoS Statistics

E. Log messages

In configuring failover settings, which of the following ports is set as the default for communicating with the backup Steelhead appliance?

A. 7600

B. 7744

C. 7766

D. 7820

E. 7850

The fair peering feature on Interceptor appliances can be enabled:

A. For each load-balancing rule, including the default rule.

B. For each load-balancing rule, excluding the default rule.

C. Only for the default rule.

D. For each load-balancing rule and in-path rule

E. For each load-balancing rule, in-path rule, including the default rule.

After completing the SRDF configuration on both Steelhead appliances and restarting the optimization service, the SRDF connections in the Current Connections report show a red protocol error icon in the Notes column. What could be a cause of this issue?

A. A SRDF protocol error can occur when attempting to optimize traffic originating from the LAN-side of the Steelhead appliance. Please check the LAN-side Symmetrix array for compatibility.

B. The red icon indicates that RiOS is optimizing the connection normally.

C. A SRDF protocol error can occur when attempting to optimize traffic originating from the WAN- side of the Steelhead appliance. Please check the WAN-side Symmetrix array for compatibility.

D. Symmetrix needs to be enabled on the EMC server.

You have a number of SteelHeads running RiOS 9.x. At each datacenter site, there are a cluster of domain controllers, one of which the SteelHead is connected to. As the volume of users on the network increase, the load which the server-side SteelHeads are placing on the connected domain controller pushes the domain to its limits, and authentication failures sometimes occur. What is the best way to address this?

A. Increase the time Kerberos tickets are cached for individual users on the SteelHeads.

B. Identify traffic which does not have a high rate of data reduction, and use in-path rules to path this traffic through.

C. Disable Kerberos authentication on the SteelHeads so as to down negotiate to NTLM, specifying multiple domain controllers during the domain-join.

D. Configure domain controller load-balancing so the SteelHead can communicate with multiple domain controllers instead of just one.

A version 9 SteelCentral Controller for SteelHead (SCC) connects to managed appliances using which protocols?

A. SNMP

B. SSH and HTTPS

C. SSH and API access

D. SSH only

E. SNMP and SSH

If data store synchronization is to be successful, which of these must be true?

A. There must be a resilient path between the SteelHeads to prevent a split brain situation.

B. The in-path IP addresses must be reachable from each other and connected physically in-path.

C. The SteelHeads must be the same model and run the same RiOS version.

D. The master must be the same or larger data store than the backup.

E. The SteelHeads must be in a serial cluster arrangement.
