Which two statements are true about a 6to4 tunnel connecting two IPv6 islands over the IPv4 Internet? (Choose two.) A. It embeds the IPv6 packet into the IPv4 payload with the protocol type set to 51. B. It works by appending the private IPv4 address (converted into hexadecimal format) to the 2002::/16 prefix. C. It embeds the IPv6 packet into the IPv4 payload with the protocol type set to 41. D. It works by appending the public IPv4 address (converted into hexadecimal format) to the 2002::/16 prefix. Answer: C,DExplanation: 6to4 embeds an IPv6 packet in the payload portion of an IPv4 packet with protocol type 41. Tosend an IPv6 packet over an IPv4 network to a 6to4 destination address, an IPv4 header withprotocol type 41 is prepended to the IPv6 packet. The IPv4 destination address for the prependedpacket header is derived from the IPv6 destination address of the inner packet (which is in theformat of a 6to4 address), by extracting the 32 bits immediately following the IPv6 destinationaddress's 2002::/16 prefix. The IPv4 source address in the prepended packet header is the IPv4address of the host or router which is sending the packet over IPv4. The resulting IPv4 packet isthen routed to its IPv4 destination address just like any other IPv4 packet. ReferencE. QUESTION NO: 354 Refer to the exhibit. Cisco 400-101 Exam "Pass Any Exam.

What will be the IP MTU of tunnel 0? QUESTION NO: 355 On an MPLS L3VPN, which two tasks are performed by the PE router? (Choose two.) A. It exchanges VPNv4 routes with other PE routers. B. It typically exchanges iBGP routing updates with the CE device. C. It distributes labels and forwards labeled packets. D. It exchanges VPNv4 routes with CE devices. E. It forwards labeled packets between CE devices. Cisco 400-101 Exam "Pass Any Exam. Any Time." - 290

Exchanges routing updates with the CE router Translates the CE routing information into VPN version 4 (VPNv4) routes Exchanges VPNv4 routes with other PE routers through the Multiprotocol Border Gateway Protocol (MP-BGP) A PE router binds a label to each customer prefix learned from a CE router and includes the label in the network reachability information for the prefix that it advertises to other PE routers. When a PE router forwards a packet received from a CE router across the provider network, it labels the packet with the label learned from the destination PE router. When the destination PE router

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
