What was the primary driver for development of IPv6? - Correct
Answer - To address the issue of IPv4 address exhaustion.
When comparing IPv4 to IPv6, which of the following statements
is true - Correct Answer - 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.
- Correct Answer - 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. - Correct Answer
- TRUE
,In IPv6, Quality of Service (QoS) is radically changed, utilizing
only the flow label for all QoS provisioning. - Correct Answer -
FALSE
Unfortunately, only RIP (Routing Information Protocol) and OSPF
(Open Shortest Path First) are capable of routing IPv6. - Correct
Answer - FALSE
What size are IPv4 and IPv6 addresses, respectively? - Correct
Answer - 32-bits, 128-bits.
IPv4 addresses are written in dotted-decimal. Which of these best
describes how IPv6 addresses are written? - Correct Answer -
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). -
Correct Answer - FALSE
, An example of a single 16-bit "hextet" in an IPv6 address could be
shown like this: - Correct Answer - :54a2:.
What is an "IID"? - Correct Answer - Interface Identifier.
How large is a typical user-centric IPv6 subnet size, for a single
subnet, using CIDR notation? - Correct Answer - /64
What does the notation "2000::/3" mean, in terms of the initial
IETF allocation for IPv6 global unicast space? - Correct Answer -
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 assignment
for a service provider? - Correct Answer - /32
Which of these prefix lengths would be a reasonable assignment
for a small single-homed commercial enterprise with no more than
15 or 20 networks? - Correct Answer - /48.
