200-901 Practice Question: Which THREE of the following are characteristics…
Which THREE of the following are characteristics of IPv6? (Select exactly three.)
⚠ Common exam trap
Cisco often tests the misconception that IPv6 still uses ARP or that its address length is 32 bits, hoping candidates confuse IPv6 with IPv4 fundamentals.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
IPv6 does not have a built-in NAT requirement.
IPv6 was designed without a built-in requirement for Network Address Translation (NAT) because its vast 128-bit address space allows every device to have a globally unique public IP address. Unlike IPv4, which relies on NAT to conserve limited address space, IPv6 restores end-to-end connectivity by default, eliminating the need for address translation at the network edge.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
IPv6 does not have a built-in NAT requirement.
Why this is correct
IPv6 was designed with enough address space to avoid NAT.
- ✓
IPv6 uses a 128-bit address space.
Why this is correct
Correct, 128-bit addresses.
- ✗
IPv6 addresses are 32 bits in length.
Why it's wrong here
IPv6 addresses are 128 bits.
- ✓
IPv6 supports stateless address autoconfiguration (SLAAC).
Why this is correct
SLAAC allows hosts to configure an address without DHCP.
- ✗
IPv6 uses ARP to resolve MAC addresses.
Why it's wrong here
IPv6 uses Neighbor Discovery Protocol (NDP) instead of ARP.
