CompTIA Network+ (N10-008) — Question 15

A network administrator decided to use SLAAC in an extensive IPv6 deployment to alleviate IP address management. The devices were properly connected into the LAN but autoconfiguration of the IP address did not occur as expected. Which of the following should the network administrator verify?

Answer options

• A. The network gateway is configured to send router advertisements.
• B. A DHCP server is present on the same broadcast domain as the clients.
• C. The devices support dual stack on the network layer.
• D. The local gateway supports anycast routing.

Correct answer: A

Explanation

The correct answer is A because for SLAAC to function, the network gateway must send out router advertisements to inform devices of their network configuration. Option B is incorrect because having a DHCP server in the same broadcast domain does not directly affect SLAAC. Option C is not relevant since SLAAC does not require dual stack support. Option D is also incorrect as anycast routing is unrelated to the autoconfiguration process of IP addresses.
