Exam 200-301 topic 1 question 113 discussion

It should be B! Only reachable from the internal network, not the internet. https://www.ciscopress.com/articles/article.asp?p=2803866&seqNum=4 Global unicast: A routable address in the IPv6 Internet, similar to a public IPv4 address. Link-local: Used only to communicate with devices on the same local link. Loopback: An address not assigned to any physical interface that can be used for a host to send an IPv6 packet to itself. Unspecified address: Used only as a source address and indicates the absence of an IPv6 address. Unique local: Similar to a private address in IPv4 (RFC 1918) and not intended to be routable in the IPv6 Internet. However, unlike RFC 1918 addresses, these addresses are not intended to be statefully translated to a global unicast address. IPv4 embedded: An IPv6 address that carries an IPv4 address in the low-order 32 bits of the address.

If "the internal network" is 1 subnet for all nodes = C If "the internal network" is more than 1 subnet for all nodes = B Best practice is probably B, easier to for scaling by implementing more subnets in the future. But it's still a Cisco question...

B. Unique local is similar to IPv4's private addresses. You can't even ping an IPv6 link local, so I wouldn't say C.

B Unique Local Addresses (ULAs) are designed for use within a single organization or site. They are not globally routable and are intended to be unique within a confined network or domain. ULAs provide internal addressing for devices within an organization's network without the need for public Internet routing.

for me B and C could be correct because Assigning either a ULA or a LLA to the device ensures that its IPv6 address is reachable only within the internal network and cannot be accessed from the public Internet. Depending on the specific requirements and network setup, the engineer can choose between these two types of addresses.

Its B, a link local address cannot be a destination address

B is correct

It is unique local, yes.

B is correct

B is the correct answer not otherwise

Only internal it's unique local

Link-local: Used only to communicate with devices on the same local link.

There is: IP address be reachable only from the internal network. (Not networkS.)

From Wikipedia, the free encyclopedia A unique local address (ULA)[1] is an Internet Protocol version 6 (IPv6) address in the address range fc00::/7.[2] These addresses are non-globally reachable[3] (routable only within the scope of private networks, but not the global IPv6 Internet). For this reason, ULAs are somewhat analogous to IPv4 private network addressing, but with significant differences. Unique local addresses may be used freely, without centralized registration, inside a single site or organization or spanning a limited number of sites or organizations.

If 1 subnet C If multiple subnets B

B is correct

Yes..B.is correct.
