.The translation mechanism isstateless and provides a 1:1 relationship between the internal addresses and external addresses.The use cases for NPTv6 outlined in the RFC includepeering with partner networks, multi homing, and redundancy and load sharing.Reference:http://www.cisco.com/c/dam/en/us/td/docs/solutions/SBA/August2012/Cisco_SBA_BN_IPv6Ad dressingGuide-Aug2012.pdfQUESTION 72A network engineer has left a NetFlow capture enabled over the weekend to gather information regarding excessive bandwidth utilization.The followingcommand is entered:switch#show flow exporter Flow_Exporter-1What is the expected output?A.configuration of the specified flow exporterB.current status of the specified flow exporterC.status and statistics of the specified flow monitorD.configuration of the specified flow monitorCorrect Answer: BSection: Infrastructure ServicesExplanationExplanation/Reference:www.vceplus.com - Download A+ VCE (latest) free Open VCE Exams - VCE to PDF Converter - VCE Exam Simulator - VCE Online - IT Certifications Explanation:show flow exporter exporter-name (Optional) Displays the current status of the specified flow exporter.Example:Device# show flow exporterFLOW_EXPORTER-1Reference: http://www.cisco.com/en/US/docs/ios-xml/ios/fnetflow/configuration/15-mt/cfg-de- fnflow-exprts.htmlQUESTION 73Which two functions are completely independent when implementing NAT64 over NAT-PT? (Choose two.)A.DNSB.NATC.port redirectionD.stateless translationE.session handlingCorrect Answer: ABSection: Infrastructure ServicesExplanationExplanation/Reference:Explanation:Network Address Translation IPv6 to IPv4, or NAT64, technology facilitates communication between IPv6-only and IPv4-only hosts and networks(whether in a transit, an access, or an edge network).This solution allows both enterprises and ISPs to accelerate IPv6 adoption while simultaneouslyhandling IPv4 address depletion.The DNS64 and NAT64 functions are completely separated, which is essential to the superiority of NAT64 over NAT-PT.Reference: http://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/enterprise-ipv6- solution/white_paper_c11-676278.htmlQUESTION 74Which two methods of deployment can you use when implementing NAT64?
