You are working on a workstation with the following MAC address: 10-01-64-AB-78-96. Which of the following will be the link-local address using the modified EUI-64 format?

FE80::1201:64FF:FEAB:7896

Your organization has been assigned a registered global routing prefix of 2001:FEED:BEEF::/48 by an ISP. Using your organization's IPv6 addressing scheme, you've used the next 16 bits beyond the global routing prefix to define the following subnets: 2001:FEED:BEEF:0001::/64 2001:FEED:BEEF:0002::/64 2001:FEED:BEEF:0003::/64 2001:FEED:BEEF:0004::/64 You need to statically assign an interface ID of 0000:0000:0000:0001 to the router interface connected to the 2001:FEED:BEEF:0003::/64 subnet. Which interface configuration command would you use to do this?

ipv6 address 2001:FEED:BEEF:0003::1/64

Your organization has decided to implement unique local unicast IPv6 addressing. A global ID of FD01:A001:0001::/48 been selected for the organization's IPv6 addressing scheme. The next 16 bits beyond the global ID have been used to define the following subnets: FD01:A001:0001:0001::/64 FD01:A001:0001:0002::/64 FD01:A001:0001:0003::/64 FD01:A001:0001:0004::/64 You need to statically assign an interface ID to a router interface connected to the FD01:A001:0001:0003::/64 subnet. To ensure uniqueness, the interface ID should be constructed using the MAC address of the router interface. Which interface configuration command would you use to do this?

ipv6 address FD01:A001:0001:0003::/64 eui-64

Based on the address prefix, for each IPv6 address on the right, identify the address type from the list on the left. (Addresses used might not represent actual addresses used in production.)

2001:6789:9078::ABCE:AFFF:FE98:0001 - Global unicast FD00::8907:FF:FE76:ABC - Unique local FEA0::AB89:9FF:FE77:1234 - Link-local FF00:98BD:6532::1 - Multicast FF02::1:2 - Multicast

Which of the following IPv6 addresses is equivalent to the IPv4 loopback address of 127.0.0.1?

::1

Consider the following IPv6 address: FE80:0000:0000:0055:0000:0000:000A:AB00 Which of the following are valid shortened forms of this address? (Select two.)

FE80::55:0000:0000:A:AB00 FE80:0000:0000:0055::000A:AB00

Which of the following are correctly-formatted IPv6 addresses? (Select three.)

FE80::AB01:7894 ::DAFC:8904 2001::78:ABC:891F

Which of the following IPv6 addresses is used by a host to contact a DHCP server?

FF02::1:2

Consider the following IPv6 address: FD01:0001:0001:005::7/64 Drag the component parts of this address on the left to the corresponding description on the right. Not all descriptions on the right have corresponding components on the left

Global Routing Prefix: Subnet ID: FD01:0001:0001:005 Interface ID: ::7 Prefix Length: /64 Global ID: 01:0001:0001 Unique Local Unicast Prefix: FD

Consider the following IPv6 address: 2001:0BEF:0BAD:0006::32/64 Drag the component parts of this address on the left to the corresponding description on the right. Not all descriptions on the right have corresponding components on the left.

Global Routing Prefix: 2001:0BEF:0BAD Subnet ID: 2001:0BEF:0BAD:0006 Interface ID: ::32 Prefix Length: /64 Global ID:

You need to design an IPv6 addressing scheme for your network. The following are key requirements for your design: Infrastructure hosts, such as routers and servers, will be assigned static interface IDs while workstations, notebooks, tablets, and phones will be assigned interface IDs dynamically. Internet access must be available to all hosts through an ISP Site-to-site WAN connections will be created using leased lines. Which type of IPv6 addressing is most appropriate for hosts in this network?

Global Unicast Addressing

Your company wants to begin the transition from IPv4 to IPv6. You want to stage the implementation on a host-by-host basis. You will enable IPv6 on existing hosts as time and budget allows. During the transition, all hosts in your site need to communicate with all other hosts. IPv6 should be used between hosts when both hosts support IPv6. NAT supported is not required. Which method should you use?

ISATAP

Which IPv6 address type is only valid within a subnet?

Link-local

Match the IPv6 prefix on the left with its description.

Link-local: FE80::/10 Multicast: FF00::/8 Unique local: FC00::/7

Your company has just started contracting with the government. As part of the contract, you have configured a special server for running a custom application. Contract terms dictate that this server use only IPv6. You have several hosts that need to communicate with this server. Hosts run only IPv4 and cannot be configured to run IPv6. Which solution would you use to allow the IPv4 clients to communicate with the IPv6 server?

NAT-PT

You have a special server at work with a custom application installed. Connections to the server that use the custom application must use IPv6. The server is currently running IPv4. You are the only person who connects to the server, and you always use your laptop for the connection. Your laptop supports both IPv4 and IPv6. The rest of your company network runs only IPv4. You need a cost-effective solution to allow your laptop to connect to the server. Your solution must also support communication through NAT servers. Which method should you use?

Teredo
