The exam options are click the respective links to be taken to the applicable Cisco web page: It IS more expensive but if you try to do it all at once, you will probably spend more money failing and doing repeats in any case!

This course is probably too expensive for an individual student but there are good books and other study aids available. The following demos provide self-guided tours of chapters from each course.

After launching a demo, you can navigate through the chapter topics using the index or the arrows, and explore the media-rich, interactive activities and labs to view the types of content available in each curriculum. Packet Tracer software is available only to Academy instructors and students free of charge, and must be previously installed on your computer. This is also the Third Edition Which of the following is the most likely organization from which an enterprise could obtain an administrative assignment of a block of IPv6 global unicast IP addresses?

Global unicast addresses are not administratively assigned by an outside organisation. Which of the following is the shortest valid abbreviation for FE Inside a quartet, any leading 0s can be omitted, and one sequence of 1 or more quartets of all 0s can be replaced with double colons:: The correct answer replaces the longer 3-quartet sequence of 0s with Which of the following answers lists a multicast IPv6 address?

Global unicast addresses begin with Similarly, unique local addresses match FD Multicast IPv6 addresses begin with FF Which of the following answers list either a protocol or function that can be used by a host to dynamically learn its own IPv6 address?

Stateless autoconfiguration also allows the assignment by finding the prefix from some nearby router and calculating the interface ID using the EUI format. Which of the following help allow an IPv6 host to learn the IP address of a default gateway on its subnet?


Stateless RS is not a valid term or feature. A — The first 64 bits represent the dynamically created interface ID.

Need help: Gotta get my CCNA by the end of august. : ccna

B — A single interface may be assigned multiple IPV6 addresses of any type. C — Every IPV6 interface contains at least one loopback address. D — Leading zeros in an IPV6 16 bit hexadecimal field are mandatory. Which three of the following are IPv6 transition mechanisms? Below is a summary of IPv6 transition technologies: This mechanism allows IPv6 sites to communicate with each other over the IPv4 network without explicit tunnel setup.

The main advantage of this technology is that it requires no end-node reconfiguration and minimal router configuration but it is not intended as a permanent solution. Which two descriptions are correct about characteristics of IPv6 unicast addressing?

A — Global addresses start with B — Link-local addresses start with FF C — Link-local addresses start with FE D — There is only one loopback address and it is:: Below is the list of common kinds of IPv6 addresses: Select the valid IPv6 addresses. Answer C is correct because it is the normal IPv6 address.

Answer E is not correct because a global-unicast IPv6 address is started with binarydenoted as The entire global-unicast IPv6 address range is how2oass Question 7 of the 9tut.

Note the double colon:: This represents 96 bits set to zero leaving 32 bits for the IPv4 address which is incorporated into the IPv6 address. Any link-layer master router. The complete IPv6 how2pxss is manually specified for the interface. This is a normal Global Unicast IPv6 address with a network prefix of 64 bits. In full it would be: This is the course we followed in College but it is probably too expensive for private study!

The format is X: X where each X is a bit hexadecimal field. Leading zeros in a field are optional AND Successive fields of zeros can be displayed as a double-colon:: This is ccan main type of IPv6 address. Format of Global Unicast Address: All Global unicast addresses begin with What does this mean?

It means that the first 3 Binary Bits out of bits are the most significant AND that the first 3 bits must match the value in hex Therefore the entire global-unicast IPv6 address range begins at Perhaps the Hex 3s have not yet been issued?


It is a One-to-Many type of address. For efficiency, a packet that is sent to an anycast address is delivered to the closest interface. For that reason, anycast can also be thought of as a One-to-Nearest type of address. The address is allocated to a cccna of servers but the packet is only delivered to the nearest one.

An example is This gives a total of 48 bits for the Routing Prefix. Therefore the enterprise can use the next 16 bits as the Subnet Prefix giving a total prefix length of 64 bits.

This allows for 2 640-282 the power of 16 subnets – a huge number. General unicast address format routing prefix size varies. Transition from IPv4 to IPv6. The transition from IPv4 to IPv6 does not have to be done all at once.

The three most common transition methods are: Both protocol stacks run on the same device. This method enables IPv4 and IPv6 to coexist. Tunneling is the encapsulation of one protocol packet within another protocol.

For example, an IPv6 packet can be encapsulated within an IPv4 protocol. Cisco IOS Releases This translation allows direct communication between hosts that use different versions of the IP protocol. In relation to Tunneling techniques see question 5 in the www.

See also a question on Chris Bryant’s website. What are two ways that some networks can use IPv6 addreses and still communicate over the Internet with their other networks that use IPv4 choose two?


Closest equivalent in IPv4 is Intended for use in private networks e. Not routable on the Internet.

This replaces the obsolete Site Local Address. Site Local Address obsolete. The site local prefix FEC However problems arose with its use and it has been replaced by the Unique Local Address system.

All Nodes on the local network segment. All Routers on the local network segment. Note the use of “9” in both multicast addresses.
