Selected Answer: B
An IPv6 address type that provides communication between subnets and cannot route on the Internet is a link-local address. Link-local addresses are used for communication within a single network segment or link, such as between devices on a local area network (LAN). They are not intended to be routable over the Internet and are not assigned to devices that need to communicate with devices on other networks. Link-local addresses are identified by the prefix "FE80::/10" and are automatically generated by the device when it is connected to a network. They are usually used in conjunction with other types of IPv6 addresses, such as global unicast addresses, which are used for communication over the Internet. It's important to note that link-local addresses are not the same as loopback addresses, which are used for communication between a device and itself and are identified by the prefix "::1/128". Loopback addresses are not used for communication with other devices.

How is Unique-local the right answer when you are saying that Link-local is the right one?

link local is wrong because link-local (fe80::/10) addresses are used for communication only within the same link (same subnet). They cannot communicate across different subnets.

The IPv6 address type that provides communication between subnets but cannot route on the Internet is the Unique Local Address (ULA). The ULA range is defined in RFC 4193 and is reserved for private use within an organization or site. It is similar to IPv4's private IP address ranges (e.g., 10.0.0.0/8, 192.168.0.0/16) and is not globally routable on the public Internet. The ULA range uses the fc00::/7 prefix and allows organizations to create their own private addressing scheme for internal network communication while ensuring uniqueness within their own network.

Selected Answer: B
Unique local unicast addresses are analogous to private IPv4 addresses in that they are used for local communications, intersite VPNs, and so on, except for one important difference – these addresses are not intended to be translated to a global unicast address. They are not routable on the internet without IPv6 NAT, but they are routable inside a limited area, such as a site.

"A IPv6 Unique Local Address is an IPv6 address in the block FC00::/7" I thought unique local addresses began with FD, not FC?

For the people asking about the link-local address. Extracted from Official Cert Guide CCNA 200-301 Volume 1 page 566: IPv6 defines rules so the packets sent to any link-local addresses should not be forwarded by any router to another subnet...

why is A not the right answer? link local, isnt routable, unique local routable within the lan.

A is not the right answer because link local addresses do not communicate with other subnets. They only communicate with devices on their local link. B is correct as it is similar to the private addresses in IPv4. They can be routed internally but not across the Internet.

From my understanding, unique local is routable (inter-vlan) not across the internet.
