   An engineer configures a new phone in Cisco UCM. The phone boots and gels an IP address when it connects to the network, however the phone fails to register with Cisco UCM. The engineer observes that the phone has a status Rejected in Cisco UCM. What must be verified first when troubleshooting the issue?

   • Awhether auto-registration is enabled in Cisco UCM
   • Bwhether the phone is in the correct VLAN
   • Cwhether the Initial Trust List and Certificate Trust List files on the phone are correct
   • Dwhether the phone’s MAC address is correct in Cisco UCM

   Show answer

   Answer: C

   Explanation

   I think the best answer here is C: A. whether auto-registration is enabled in Cisco UCM - Auto reg isn't mentioned and is not required for a manually configured phone to register. B. whether the phone is in the correct VLAN - If the phone is rejected it was able to communicate with the CUCM and attempt to download it's configuration indicating there is not a network issue with connecting to TFTP or the CUCM. C. whether the Initial Trust List and Certificate Trust List files on the phone are correct - An expired ITL or an ITL from a different server will cause a Rejection. D. whether the phone’s MAC address is correct in Cisco UCM - If the MAC was incorrect it would not show rejected, it would show as none or unknown. The MAC has to be right for it to get rejected in the first place.

   SIP proxies have operations defined in RFC 3261 and supporting extensions. Though no IETF RFC completely defines how SBCs must function, SBCs evolved over the years. Which two operations demonstrate the high-level differences between SBCs and SIP proxies? (Choose two.)

   • ASIP proxies are SDP-aware and can change the SDP bodies.
   • BSIP proxies add a Via header and optionally a Record-Route header, and the rest of the headers are left untouched.
   • CSBCs can modify headers such as To, From, Contact, and Call-ID. It can introduce new headers into the SIP message.
   • DStateful proxies are context-aware and can terminate communication sessions by themselves.
   • ESBCs are capable of interworking completely different protocols to set up, modify, and tear down communication sessions. It includes SIP, H.323, and MGCP protocols.

   An engineer configures Class-Based Weighted Fair Queuing, but must still configure Low Latency Queuing to prioritize voice audio traffic and guarantee 5 Mbps of bandwidth. Which Cisco IOS command must be run in the voice class map?

   • Apriority
   • Bpriority 5
   • Cpriority 5000
   • Dpriority level 5

   Show answer

   Answer: C

   Explanation

   From this doc: https://www.cisco.com/c/en/us/support/docs/quality-of-service-qos/qos-packet-marking/10100-priorityvsbw.html The Cisco IOS Configuration Guides describe the priority command as a reserve for "a priority queue with a specified amount of available bandwidth for CBWFQ traffic…to give priority to a traffic class based on the amount of available bandwidth within a traffic policy." The next example explains what these definitions mean. You create a priority queue with these sets of commands: Router(config)#policy-map policy-name Router(config-pmap)#class class-name Router(config-pmap-c)#priority kpbs [bytes]

   An engineer is configuring a PRI card on a Cisco ISR 4300 Series Router. When the engineer configures the voice PRI on the router, this error is received: "T1 0/1/0: No DSP resources to configure voice feature". Which action must the engineer take to resolve the issue if a PVDM card was installed in the motherboard?

   • AInstall the NIM card on a different slot.
   • BReplace the memory slot in the motherboard.
   • CReplace the flashcard, restart the router, and try it again.
   • DInstall the PVDM directly to the NIM card.

   Show answer

   Answer: D

   Explanation

   There is only one PVDM slot on the motherboard. The Time Division Multiplexing (TDM) cards cannot use the motherboard PVDMs. Dependent upon the number of channels required, the appropriate DSP module is installed on the NIM. For IP services such as to transcode and conference, the PVDM4 DSP module can be installed on the motherboard of the ISR 4000 Series platform. If the show inventory output shows this information, it signifies that the PVDM card is installed on the motherboard. https://www.cisco.com/c/en/us/support/docs/routers/4000-series-integrated-services-routers/118792-config-isr-00.html I think D
