NEW QUESTION 4

Manually moving an entry from the SSL grey list to the white list on a SteelHead enables trust between which hosts?

• A. Client-side SteelHead and server-side SteelHead
• B. Client PC and server-side SteelHead
• C. Client-side SteelHead and server
• D. Server-side SteelHead and server

Answer: A

Explanation:
The Riverbed SSL solution optimizes data transfers that are encrypted using SSL, provided that SteelHeads are deployed locally to both the client-side and server-side of the network.
Note: Secure Peering Using the Self-Signed Peer White, Gray, and Black Lists
You can use peering lists to configure peer certificates on SteelHeads running RiOS 5.0 or later. When SSL optimization is enabled, and an optimizable SSL connection is attempted across the SteelHeads, the remote peer is detected and its peering certificate is automatically populated into the self-signed peer gray list. The connection remains unoptimized because the remote peer is listed in the self-signed peer gray list.
You can examine the peer certificate for authenticity and move any peer from the gray list to either the white list or the black list. If you trust the remote peer, move it into the self-signed peer white list to begin optimizing the SSL connection. If you do not trust the remote peer, move it into the self-signed peer black list to prevent the SSL connection from being optimized.

NEW QUESTION 9

How does the SteelHead monitor path availability in Path Selection?

• A. Path availability is not monitored until traffic is sent over that pat
• B. Then the SteelHead uses standard TCP timeouts to monitor path integrity.
• C. The SteelHead uses ICMP ping to monitor path availability.
• D. The SteelHead creates an inner channel on each path and keep-alive packets are used to track availability.
• E. UDP keep-alives are periodically sent across each pat
• F. If a SteelHead does not receive two of these within a pre-defined timeout period, the path is declared down.

Answer: B

Explanation:
RiOS 8.5 path selection technology provides the ability to deterministically re-direct select traffic and application flows through alternate WAN routes based on service metrics, such as path availability and priority.
Availability is determined by whether the host at the remote end of a path can be reached via endto-end Internet Control Messaging Protocol (ICMP):
