Objective 1.8
200-301Configure and verify IPv6 addressing and prefix.
Objective 1.8 sits in Network Fundamentals, which carries 20% of the CCNA exam. The questions below are original, written from the official objective title above, and each explanation cites the Cisco page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
Hosts in VLAN 10 cannot reach hosts in VLAN 20 over IPv6.
Switch# show run interface Vlan10interface Vlan10 ipv6 address 2001:DB8:A:10::1/64!Switch# show run interface Vlan20interface Vlan20 ipv6 address 2001:DB8:A:20::1/64!Switch# show ipv6 route% IPv6 routing not enabledWhat is missing?
Correct.
Checked against cisco.com, August 2026Concept
Giving interfaces addresses makes a device reachable on each of those segments. Moving traffic between the segments is a separate function that has to be switched on at the global level, and until it is, every interface behaves as an endpoint rather than as a transit point.
Why B
Both SVIs already carry a global address, so each VLAN can reach the switch itself. Forwarding between them stays off until the global command is entered, which is why the route table reports that routing is not enabled and transit traffic is discarded.

Now you: objective 1.8 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An engineer checks an SVI before troubleshooting address resolution.
Device# show ipv6 interface Vlan1Vlan1 is up, line protocol is up IPv6 is enabled, link-local address is FE80::20B:46FF:FE2F:D940 Global unicast address(es): 3FFE:C000:0:1:20B:46FF:FE2F:D940, subnet is 3FFE:C000:0:1::/64 [EUI] Joined group address(es): FF02::1 FF02::2 FF02::1:FF2F:D940 MTU is 1500 bytesWhat role does the third joined group serve?
Sample question 2 of 3
IPv6 hosts on a segment obtain usable addresses with no DHCP server and nothing typed on the hosts. Which mechanism is at work?
Sample question 3 of 3
A host builds its own global IPv6 address. Which two inputs does the stateless mechanism combine?
That’s 3 of the full CCNA bank.
