CompTIA Network+ (N10-007) — Question 404

A network technician wants to address PCs on a subnet with IPv6 in addition to IPv4. The subnet currently uses a DHCP server that only supports IPv4. Which of the following should the technician use to assign IPv6 addresses automatically without DHCP?

Answer options

• A. APIPA
• B. MAC reservations
• C. EUI-64
• D. IPv4 to IPv6 tunnel

Correct answer: C

Explanation

The correct option is C, EUI-64, as it is a method used to automatically create IPv6 addresses by deriving them from the MAC address of a device. Other options like APIPA are for automatic IPv4 addressing, MAC reservations are for static address assignment, and an IPv4 to IPv6 tunnel is used for communication between IPv6 and IPv4 networks, not for assigning addresses.
