B.debug call script
C.debug custom script
D.debug voice application
Correct Answers: D

5: What is the impact of setting an RSVP policy per location pair with a default interlocation RSVP service policy?
A.additional bandwidth capacity will be added to the default interlocation RSVP service policy
B.the RSVP policy will only be associated with one type of call; for example, if it is associated with video calls, audio calls will not be impacted
C.an RSVP mandatory mid-call retry counter will be added to calls that encounter mid-call retry errors
D.the default interlocation RSVP service policy will be overridden
Correct Answers: D

6: Which two methods can be used to challenge the identity of an IP phone from a Cisco Unified Communications Manager server? (Choose two.)

B.TLS
C.SRTP
D.digest authentication
E.HTTPS
F.SFTP
Correct Answers: B D

7: Which two statements about phone hardening are accurate? (Choose two.)
A.GARPs can be allowed in order to monitor phone access more closely.
B.By default, Cisco Unified Communications Manager disables the PC port on all Cisco IP phones that have a PC port. It is possible to enable the PC Port setting in the Phone Configuration window of Cisco Unified Communications Manager Administration.
C.Disabling settings access automatically sets the current Contrast, Ring Type, Network Configuration, Model Information, Status, and Volume settings to the default for that phone.
D.Disabling PC voice VLAN access will cause packets received from the PC port that uses the voice VLAN tag to drop.
E.Disabling settings access prohibits access to all the options that are normally displayed when the Settings button on the phone is pressed.
Correct Answers: D E

8: A remote site has lost connectivity with the centralized Cisco Unified Communications Manager cluster. The remote site H.323 gateway is configured to support SRST. Which three statements about SRST are true? (Choose three.)
A.The remote site IP phones initiate registration with the SRST gateway.
B.The gateway sends Keepalives to Cisco Unified Communications Manager to determine when connectivity is restored.
C.The IP phones send Keepalives to Cisco Unified Communications Manager to determine when connectivity is restored.
D.The gateway fallback process takes control of the voice ports so calls can be placed to the PSTN.
E.The IP phones re-register with Cisco Unified Communications Manager when they see responses to the Keepalives.
F.When connectivity is restored Cisco Unified Communications Manager instructs the phones to unregister with the gateway and re-register with Cisco Unified Communications Manager.
Correct Answers: A C E

9: How is recovery from SRST mode back to Cisco Unified Communications Manager call processing accomplished?
A.The IP phones receive Keepalives from Cisco Unified Communications Manager. They then register with Cisco Unified Communications Manager and cancel their registration with the SRST gateway.
B.The IP phones receive a response to Keepalives sent to Cisco Unified Communications Manager. They then register with Cisco Unified Communications Manager and cancel their registration with the SRST gateway.
C.The SRST gateway receives Keepalives from Cisco Unified Communications Manager. The SRST gateway then rejects the IP phone registrations with instructions to register with Cisco Unified Communications Manager.
D.The SRST gateway receives a response to Keepalives sent to Cisco Unified Communications Manager. The SRST gateway then rejects the IP phone registrations with instructions to register with Cisco Unified Communications Manager.
Correct Answers: B

10: When you configure a region to use the G.729 codec, which other codecs can be utilized in the region?
A.The region can use all the codecs supported by Cisco Unified Communications Manager.
B.The region will use all of the codecs supported by Cisco Unified Communications Manager as long as a software Media Termination Point is available.
C.The region will only use the codec configured in the region configuration field and any other codecs of equal or lower bandwidth.
D.The region will use the configured codec and the default codec as long as it does not exceed the configured bandwidth for the region.
