Q10Security
While investigating why Mobile and Remote Access to Cisco TelePresence equipment no longer works for an organization, you find that several administrators may have made configuration changes without anyone knowing. Internal communication appears to work, but no external system can register or place calls anywhere. After gathering symptoms, you also find that no internal systems can call out. What is missing from TraversalZone that causes this issue?

Correct Answer A. Link to DefaultZone
Explanation below :
"Using Links and Pipes to Manage Access and Bandwidth
You can also manage calls from unrecognized systems and endpoints by configuring the "links" and "pipes" associated with the Default Zone. For example, you can delete the default links to prevent any incoming calls from unrecognized endpoints, or apply pipes to the default links to control the bandwidth consumed by incoming calls from unrecognized endpoints."

Selected Answer: A
The Expressway comes preconfigured with the Default Zone and default links between it and the Traversal Subzone. You can also manage calls from unrecognized systems and endpoints by setting the "links" and "pipes" tied to the Default Zone.
