Which action must be taken to assign a global unicast IPv6 address on an interface that is derived from the MAC address of that interface?
To assign a global unicast IPv6 address on an interface derived from the MAC address of that interface, you must enable Stateless Address Auto-Configuration (SLAAC) on the interface. SLAAC allows devices to automatically generate their own IPv6 addresses using the MAC address in conjunction with the network prefix received from router advertisements. This process typically involves using the EUI-64 format to extend the MAC address to 64 bits, which then becomes part of the IPv6 address.
i love how you can literally click for the correct answer but theres still people that come here and leave a comment saying," C is the correct answer"
The more people agreeing with the answer helps me sleep better at night.
they leave correct answer comment cause some question's answers on this website are wrong.
you must be new to these types of questions and answers. The reason it's done is because some answers can be incorrect and the more ppl input you get a better idea if the answer is valid or not.
Also, if you see different answers from different people, you will try to research, investigate, and then give a good opinion and feedback to everyone interested in the question!!!!!
For anyone that read @dave1992 comment, don't worry! The reason people doing it is because there is a lot of INCORRECT answer especially from #423 - #1057 ( I haven't check anything after that yet). So the more people COMMENTING it, the more it help others validate the answer so when you sit on the actual exam you know you got it right. this user @dave1992 here is just being a Smart As*. the saying goes: if you can't contribute positively, then just shut the F up.
C is the answer https://howdoesinternetwork.com/2013/slaac-ipv6-stateless-address-autoconfiguration
What is SLAAC? SLAAC stands for Stateless Address Autoconfiguration and the name pretty much explains what it does. It is a mechanism that enables each host on the network to auto-configure a unique IPv6 address without any device keeping track of which address is assigned to which node C is ok
Ref: IPv6 Configuration Guide, Cisco IOS XE Release 3SE (Catalyst 3850 Switches) “C H A P T E R 5 … SLAAC Address Assignment The most common method for IPv6 client address assignment is Stateless Address Auto-Configuration (SLAAC). SLAAC provides simple plug-and-play connectivity where clients self-assign an address based on the IPv6 prefix. This process is achieved. Stateless Address Auto-Configuration (SLAAC) is configured as follows: … • Hosts take the first 64 bits of the IPv6 prefix from the Router Advertisement message and combines it with the 64 bit EUI-64 address (in the case of ethernet, this is created from the MAC Address) to create a global unicast message. The host also uses the source IP address, in the IP header, of the Router Advertisement message, as its default gateway. The last 64 bits of the IP v6 address can be learned based on the following 2 algorithms: • EUI-64 which is based on the MAC address of the interface, or • Private addresses that are randomly generated. …”
C is correct SLAAC is a feature of IPv6 that allows devices to automatically configure their own IPv6 addresses without the need for a central server. When SLAAC is enabled, a device generates its interface identifier using its MAC address and combines it with the network prefix received from a router's advertisement.
Enable Stateless Address Auto-Configuration (SLAAC)
SLAAC is designed to be a simple, automatic approach to assigning IPv6 addresses. It is defined in RFC4862 and is specifically used to assign only a global unicast IPv6 address, an IPv6 prefix length, and, optionally, a default router.
Thanks for the comment. Followed the below Cisco article and other no Ciscos but could not gererate a global address automatically. I will stopped there cause fixation doesnt help.

Has anyone done the exam recently?
C is right. https://www.amarchaudhari.me/enable-ipv6-slaac-on-cisco-routers/
Correct Answer: C
C for me Contact me for full questions <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c7aaa6b3b3aeb3aeb487a8b2b3aba8a8ace9a4a8aa">[email protected]</a>
So how do we know the actual correct answer now? because i thought B is the Correct answer, and it made sense for me. Can someone Clarify?
B. Disable the EUI-64 bit process. The EUI-64 process automatically modifies the interface identifier portion of the IPv6 address based on the MAC address. By disabling the EUI-64 process, you can use other methods for generating the interface identifier, such as manual configuration or DHCPv6.
Correct answer is B
By default, when generating an IPv6 address from a MAC address, the EUI-64 process is used. This process involves taking the 48-bit MAC address and inserting "FFFE" in the middle, resulting in a 64-bit interface identifier. However, this method can potentially compromise privacy, as the MAC address can be easily traced back to the device.
