Section 8 – SAF

QUESTION 1
Refer to the exhibit.
When the user of a phone registered to the Cisco Unified Communications Manager places a call to 3001 when the SAF network is down, what happens?
A.    The call fails.
B.    The call is rerouted to the PSTN with the constructed PSTN number as +442288223001
C.    The call is rerouted to the PSTN with the constructed PSTN number as 442288223001
D.    The call is rerouted to the PSTN with the constructed PSTN number as 0002288223001
E.    The call is rerouted to the PSTN with the constructed PSTN number as +0002288223001
Answer: C
Explanation:
OK, SAF, see 5-43 CIPT2,check the ToDID field number 0:442288223001

QUESTION 2
Refer to the exhibit.
What should the destination IP address be configured as on the HQ and BR1 SIP trunks?
A.    The HQ SIP trunk destination IP address should be 10.1.6.10. The BR1 SIP trunk destination IP address should be 10.1.5.10
B.    The destination IP address is not configurable. Each cluster will learn about the remote trunk IP address through SAF learned routes.
C.    The destination IP address will be learned automatically and configured on the SIP trunks after the Cisco Unified Communications Managers discover themselves.
D.    The HQ SIP trunk destination IP address should be the HQ SAF Forwarder IP address. The BR1 SIP trunk destination IP address should be the BR1 SAF Forwarder IP address.
Answer: B
Explanation:
Ok. See 5-40.
You can configure one SAF-enabled SIP trunk and one SAF-enabled H.323 trunk. With a SAF-enabled H.323 trunk, you have to first add a standard nongatekeepercontrolled ICT and then check the Enable SAF check box. Once the check box is checked, the IP address field is disabled. The reason is that the configured trunk does not refer to a particular destination IP address but instead acts as a template for a dynamically created trunk once a SAF call is placed. The destination IP address is then taken from the learned SAF service data.
The same concept applies to the SAF-enabled SIP trunk. The only difference is that the SAFenabled SIP trunk is a special trunk service type, which is selected before the trunk configuration page is shown. Therefore, there is no extra check box like there is at the nongatekeeper-controlled ICT. The SAF-enabled SIP trunk also does not have a destination IP address field.
