70-410 Test Bank, Lesson 10, Configuring IPv4 and IPv6 Addressing

1. What is the primary reason IPv6 has not completely replaced IPv4?

a. Administrators are hesitant and reluctant to change.

2. As defined by the original Internet Protocol standard, what are the three classes of IP addresses used for networks, and what differentiates them?

a. Class A, B, C, differing by how many bits distinguish the networks from the hosts

10. What is a tunneling protocol that emulates an IPv6 link using an IPv4 network, primarily for Windows workstation operating systems?

a. ISATAP

2. Your company environment includes Windows Server versions 2003, 2008 (including R2) and 2012 (including R2). Desktops range from Windows XP and Vista. To transition to IPv6, what versions have IPv6 support running by default?

a. Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, and Vista

1. In the IPv6 space, what is the equivalent of a registered IPv4 address, routable worldwide and unique on the Internet?

a. global unicast address

6. What is the primary benefit of the IPv6 address space over the IPv4 address space?

a. number of possible hosts and networks

3. Given the IPv6 address: 21cd:0053:0000:0000/64, what does the "slash 64" at the end signify?

a. the square of the number of address bytes

5. Certain IPv6 addresses can be contracted. Which of the following answers is the contracted form of 21cd:0053:0000:0000/64?

d. 21cd:53::/64

11. What encapsulates IPv6 packets within User Datagram Protocol (UDP) datagrams between two registered IPv4 nodes in order to traverse IPv4 networks?

d. Teredo

2. In the IPv6 space, what kind of network address do systems automatically assign themselves, similarly to an APIPA address in IPv4?

d. link-local unicast address

14. What is an example of a valid IPv6 address

b. 21cd:0053:0000:0000:e8bb:04f2:003c:c394

9. What is the technology intended to help transition IPv4 networks to IPv6, by expressing IPv4 addresses in IPv6 format?

b. 6to4

4. What is Intra-Site Automatic Tunnel Addressing Protocol (ISATAP)?

b. ISATAP emulates an IPv6 link for use on an IPv4 network.

1. Which IPv4-to-IPv6 transition technology works through NAT IPv4 routers by establishing tunnel endpoints behind non-IPv6 routers that encapsulate IPv6 packets with UDP datagrams?

b. Teredo

4. Given the IPv6 address: 21cd:001b:0000:0000/8, what does the "/8" at the end signify?

b. network bits

7. In general terms, there are three ways a computer receives an IPv4 or IPv6 address. Which of the following is NOT one of them?

b. peer allocation

13. How does Classless Inter-Domain Routing help reduce waste of IP addresses?

b. subnetting method that divides between network bits and host bits anywhere, not only between octets

3. In the IPv6 space, what are the equivalent of the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 private network addresses in IPv4?

b. unique local unicast address

15. What is an example of a valid IPv4 address?

c. 192.29.1.42

3. What is an example of Automatic Private IP Addressing (APIPA) in IPv4?

c. A Windows workstation assigns itself an address on the 169.254.0.0./16 network

12. What is a subnetting method that enables you to place the division between the network bits and the host bits anywhere in the address, not just between octets?

c. CIDR

8. Rather than manually assign IPv6 addresses to computers, how can administrators ensure each Windows computer receives a link-local unicast address upon starting?

c. Stateless IPv6 Address Autoconfiguration

4. What IPv6 address type functions to identify the routers within a given address scope and send traffic to the nearest router, as determined by the local routing protocols?

c. anycast address
