NCTI Questions and Answers Graded A Question ✔✔Answer What was the primary driver for development of IPv6? ✔✔To address the issue of IPv4 address exhaustion. When comparing IPv4 to IPv6, w... hich of the following statements is true ✔✔IPv4 uses a 32-bit address scheme, while IPv6 uses a 128-bit address scheme. In IPv6-enabled networks, static addressing is no longer allowed. ✔✔FALSE Without IPv4's network address translation (NAT), IPv6 offers simpler packet construction and better support for peer-to-peer and mobile-to-mobile types of communications. ✔✔TRUE In IPv6, Quality of Service (QoS) is radically changed, utilizing only the flow label for all QoS provisioning. ✔✔FALSE Unfortunately, only RIP (Routing Information Protocol) and OSPF (Open Shortest Path First) are capable of routing IPv6. ✔✔FALSE What size are IPv4 and IPv6 addresses, respectively? ✔✔32-bits, 128-bits. IPv4 addresses are written in dotted-decimal. Which of these best describes how IPv6 addresses are written? ✔✔Hexadecimal notation, dropping leading zeros in each hextet, using the "::" notation to represent missing all-zero hextets. IPv6 addresses are written in Binary Coded Decimal (BCD). ✔✔FALSE An example of a single 16-bit "hextet" in an IPv6 address could be shown like this: ✔✔:54a2:. What is an "IID"? ✔✔Interface Identifier. How large is a typical user-centric IPv6 subnet size, for a single subnet, using CIDR notation? ✔✔/64 What does the notation "2000::/3" mean, in terms of the initial IETF allocation for IPv6 global unicast space? ✔✔That global unicast addresses always start with the first three bits "001" (first 3 bits of the address per the "/3" notation). Which of these prefix lengths would be a reasonable assign [Show More]
