  6. 6. Cisco 350-029 ExamExplanation:QUESTION NO: 11In the Carrier Support Carrier (CsC) feature, which two protocols run CSC-PE and CSC-CS(Choose two)A. EBGPv4 with a sending communityB. IGP and LDPC. EBGPv4 with a sending labelD. IGP and EBGPv4E. IGP and RSVPANSWER: B,DExplanation:QUESTION NO: 12Which three are optional extensions of the Frame Relay Local Management Interfacespecification? (Choose three)A. switched virtual circuitB. virtual circuit statusC. simple flow controlD. multicastingE. permanent virtual circuitANSWER: B,C,D Explanation:http://www.cisco.com/en/US/docs/internetworking/troubleshooting/guide/tr1918.htm#wp1020573lLMI Extensions In addition to the basic Frame Relay protocol functions for transferring data, theconsortium Frame Relay specification includes LMI extensions that make supporting large,complex internetworks easier. Some LMI extensions are referred to as "common" and areexpected to be implemented by everyone who adopts the specification. Other LMI functions arereferred to as "optional." A summary of the LMI extensions follows:•Virtual circuit status messages(common)—Provide communication and synchronization between the network and the userdevice, periodically reporting the existence of new PVCs and the deletion of already existingPVCs, and generally provide information about PVC integrity. Virtual circuit status messagesprevent the sending of data into black holes—that is, over PVCs that no longer exist.•Multicasting 6
  7. 7. Cisco 350-029 Exam(optional)—Allows a sender to transmit a single frame but have it delivered by the network tomultiple recipients. Thus, multicasting supports the efficient conveyance of routing protocolmessages and address resolution procedures that typically must be sent to many destinationssimultaneously.•Global addressing (optional)—Gives connection identifiers global rather than localsignificance, allowing them to be used to identify a specific interface to the Frame Relay network.Global addressing makes the Frame Relay network resemble a local-area network (LAN) in termsof addressing; Address Resolution Protocols, therefore, perform over Frame Relay exactly as theydo over a LAN.•Simple flow control (optional)—Provides for an XON/XOFF flow controlmechanism that applies to the entire Frame Relay interface. It is intended for devices whosehigher layers cannot use the congestion notification bits and that need some level of flow control.QUESTION NO: 13Which two models are the models of DiffServ-Aware Traffic Engineering? (Choose two)A. Policy-based ModelB. Class based ModelC. Russian Doll ModelD. Global Tunnel ModelE. Maximum Allocation ModelANSWER: C,EExplanation:QUESTION NO: 14Refer to the exhibit 7
