IPv6 design is one of the hottest topic nowadays due to IPv4 address exhaustion. Most of the RIR (Regional Internet Registries) allocated their available IPv4 addresses already.
Migration to IPv6 only network and understanding IPv6 transition mechanisms such as Dual Stack IPv6 design, IPv6 tunnelling mechanisms and IPv6 translation mechanisms such as NATPT, NAT 64 + DNS64 , SLB 64 is very important.
All are the mechanisms have pros and cons and understanding those is a good consultant opportunity for the network designers.
If you are not good at IPv6, you should start today. You might think that there are more important topics such as SDN, Cloud, IOT but that is not true. IPv6 is a foundational mechanism for all of them and you can’t have successful SDN, Cloud or IOT design without solid IPv6 knowledge.
It is not too late, start test your IPv6 design knowledge with this test and be honest yourself ! Identify your weak areas in IPv6 and start study. This website and my design training course together cover all aspects of IPv6 design.
There are 30 IPv6 design questions and answers in this test.
There are IPv6 addressing design, IPV6 migration and transition mechanisms (Dual Stack, Tunnelling, Translation, IPv6 Only) design, IPv6 multicast,IPv6 security, IPv6 routing and IPv6 Business Cases questions in this test.
You should finish in 100 minutes.
