    Q6 ospfv3 does ipv6

    I agree with that. OSPF with no extension considered to be OSPF version 1 supports no IPv6. Poorly asked question!

    As long as it is not mentioned which OSPF they are asking for, it is considered OSPF for IPv4

    Considering that OSPF and IS-IS are the only two link state protocols offered for the answer, the answer should be B and E. OSPFv3 supports IPv6. The question is poorly written.

    EIGRP also supports IPv6, doesn’t it….

    You are right, but it says link state routing protocol. EIGRP is advanced distance vector routing protocol. It is not link state routing protocol.

    Q2: 2000000+ hosts, 10000+ routers, partner and customer peering. Why internet connectivity? They are their own micro-internet!

    If all hosts will be located in area that is reasonable to connect (by cable or leased line) it can be part of the Internet when RIPE will assign AS for this Company.

    In this situation we have global company with sites distributed over the globe. It is not economically effective to buy lines or lambdas from existing operators. Even It can be impossible. Try to imagine how to connect some Ulan Bator with Caracas? It is economically feasible.
    Thats why this company use Internet.
