NEW QUESTION # 136
Which method is used to send the incoming call request to the client when the traversal server receives an incoming call for the traversal client?

A. opening an outbound connection directly to the client through the firewall
B. using an existing keep alive connection opened by the client
C. requesting for permission from the firewall
D. opening an inbound connection directly to the client through the firewall

Answer: B

Explanation:
When the traversal server (Expressway-E) receives an incoming call for the traversal client (Expressway-C), it uses the existing keepalive connection that was initiated by the traversal client. This is a core principle of the Mobile and Remote Access (MRA) architecture, which relies on outbound connections from inside to outside to traverse NAT/firewalls securely and without requiring inbound openings.

NEW QUESTION # 137

A. * transform with a pattern string of *(.*)@example.com(:5060)?"
* replace a suing of \1@example.com
B. * transform with a pattern string of "(.*)@example.com(:5060)?"
* replace a string of \1@example.com\2
C. search rule with a pattern string of "(.*)@example.com(:5060)?"
* replace a string of \1@example.com\2
D. * search rule with a pattern string of "(.*)@example.com(:5050)?"
