NEW QUESTION 5

The SteelHead makes a connection to its peers using the Out of Band splice. What does the OOB splice do?

• A. All optimized connections flow over the OOB splice.
• B. The OBB splice is only used by SteelHead mobile clients.
• C. The OBB splice is only used to check the peer SteelHead is available.
• D. It is control channel that is used to exchange version and feature information between SteelHeads.

Answer: D

Explanation:
An OOB splice is an independent, separate TCP connection made on the first connection between two peer Steelhead appliances used to transfer version, licensing and other OOB data between peer Steelhead appliances. An OOB connection must exist between two peers for connections between these peers to be optimized. If the OOB splice dies all optimized connections on the peer Steelhead appliances will be terminated.

NEW QUESTION 18

A server side SteelHead deployment is to be out-of-path (SSOOP).
Which of the below are limitations compared to physical or virtual in-path? (Choose two.)

• A. Auto discovery is not supported.
• B. Port or full transparency is not supported.
• C. Only one SteelHead is supported on the server side.
• D. Data store synchronization is not possible.
• E. Only enhanced auto discovery can be used.

Answer: AC

Explanation:
A: OOP configuration does not support auto-discovery. You must create a fixed-target rule on the clientside Steelhead.
C: An out-of-path deployment is generally located on the server-side and is often described as a server-side outof-path deployment.
In an out-of-path deployment, only a SteelHead primary interface is required to connect to the network. The SteelHead can be connected anywhere in the LAN. An out-of-path SteelHead deployment does not have a redirecting device. You configure fixed-target in-path rules for the client-side SteelHead. The fixed-target
in-path rules point to the primary IP address of the out-of-path SteelHead. The out-of-path SteelHead uses its primary IP address when communicating to the server. The remote SteelHead must be deployed either in a physical or virtual in-path mode.

NEW QUESTION 26

Automatic registration of devices with the SteelCentral Controller for SteelHead (SCC) requires which one of the following?

• A. RiOS 8.0 for SteelHead and 4.0 for Interceptor
• B. The SCC must have joined the Windows domain
• C. Pre-trusted SSL certificates on the devices and SCC
• D. The serial number of the managed device to be preconfigured in the SCC
• E. The name “riverbedcmc” to be an entry in DNS resolving to the SCC primary IP address

Answer: E

Explanation:
To use automatic registration, prepare the appliance for registration with the SCC by entering the IP address or DNS-registered hostname of the SCC when you run the configuration wizard on the appliance. Riverbed recommends that you set up your DNS servers to resolve riverbedcmc to the primary interface IP address of your SCC. If you configure your DHCP servers to forward the correct DNS settings, any appliance added into the network and powered on should automatically register with the SCC.
Alternatively, you can use the cmc enable and cmc hostname commands. If you do not change the default hostname, it remains riverbedcmc.
