NAT64B. 6RDC. 6to4 tunnelsD. Carrier-grade NATAnswer: DExplanation:Carrier Grade NAT is a large-scale NAT, capable of providing private-IPv4-to-public-IPv4 translation in the order of millions of translations. Carrier Grade NAT can support several hundred thousand subscribers with the bandwidth throughput of at least 10Gb/s full-duplex. With IPv4 addresses reaching depletion, Carrier Grade NAT is vital in providing private IPv4 connectivity to the public IPv4 internet. In addition, Carrier Grade NAT is not limited to IPv4 NAT; it can also translate between IPv4 and IPv6 addresses.New QuestionRefer to the exhibit.

(Choose two.)A. BFDB. NSF/SSOC. PIM NSRD. PIM triggered joinE. IGMP triggered reportF. MSDPAnswer: BDExplanation:Triggered joins are sent when the primary or the secondary RPF information changes. No RPF change prunes are sent for MoFRR streams.mofrrTo perform a fast convergence (multicast-only fast reroute, or MoFRR) of specified routes/flows when a failure is detected on one of multiple equal-cost paths between the router and the source, use the mofrr command under PIM configuration mode.mofrr rib acl_nameno rib acl_nameNew QuestionWhich two statements correctly describe the RPF check when a multicast packet arrives at a router? (Choose two.)A. The router looks up the source address in the unicast routing table to determine if the packet has arrived on the interface that is on the reverse path back to the sourceB. The router looks up the destination address in the unicast routing table to determine if the packet has arrived on the interface that is on the reverse path back to the destinationC. If the packet has arrived on the interface leading back to the destination, the RPF check passes and the packet is forwarded. If the RPF check fails, the packet is droppedD. If the packet has arrived on the interface leading back to the source, the RPF check passes and the packet is forwarded. If the RPF check fails, the packet is droppedAnswer: ADExplanation:Reverse Path Forwarding (RPF)RPF is a fundamental concept in multicast routing that enables routers to correctly forward multicast traffic down the distribution tree. RPF makes use of the existing unicast routing table to determine the upstream and downstream neighbors. A router will only forward a multicast packet if it is received on the upstream interface.This RPF check helps to guarantee that the distribution tree will be loop free.RPF CheckWhen a multicast packet arrives at a router, the router will perform an RPF check on the packet. If the RPF check is successful, the packet will be forwarded. Otherwise it will be dropped.For traffic flowing down a source tree, the RPF check procedure works as follows:Step 1. Router looks up the source address in the unicast routing table to determine if it has arrived on the interface that is on the reverse path back to the source.Step 2. If packet has arrived on the interface leading back to the source, the RPF check is successful and the packet will be forwarded.Step 3. If the RPF check in 2 fails, the packet is dropped.!!!RECOMMEND!!!1.|2019 Latest 642-885 Exam Dumps (PDF & VCE) Instant Download:https://www.braindump2go.com/642-885.html2.|2019 Latest 642-885 Study Guide Video Instant Download: YouTube Video: YouTube.com/watch?v=M1BVAH--VqE --------------------------------------------------- Images: --------------------------------------------------- --------------------------------------------------- Post date: 2019-06-14 07:21:06 Post date GMT: 2019-06-14 07:21:06 Post modified date: 2019-06-14 07:21:06 Post modified date GMT: 2019-06-14 07:21:06 ____________________________________________________________________________________________ Export of Post and Page as text file has been powered by [ Universal Post Manager ] plugin from www.gconverters.com
