Quick Answer
The correct mapping is that Stateful DHCPv6 assigns both the IPv6 address and other configuration parameters, while Stateless DHCPv6 provides only parameters like DNS and domain information, with the IPv6 address coming from SLAAC. This distinction is rooted in how each mode handles address assignment: Stateful DHCPv6 maintains a lease database and assigns a full address, whereas Stateless DHCPv6 relies on Router Advertisements (RAs) for the prefix and the host’s EUI-64 or privacy extension for the interface identifier, then supplements with additional options. On the ENCOR 350-401 exam, this drag-and-drop task tests your ability to differentiate these DHCPv6 modes and SLAAC, often paired with DHCPv6-PD for prefix delegation and RA Guard as a security feature that blocks unauthorized RAs. A common trap is confusing Stateless DHCPv6 with SLAAC—remember that SLAAC provides the address via RAs, while Stateless DHCPv6 only fills in the missing parameters. A useful mnemonic: “Stateful gives the whole address; Stateless gives the extras; SLAAC gives the prefix and lets the host finish.”
350-401 NAT and DHCP Practice Question
This 350-401 practice question tests your understanding of nat and dhcp. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
✓
Stateful DHCPv6: Server assigns both IPv6 address and configuration parameters
Stateful DHCPv6 assigns both IPv6 address and other parameters. Stateless DHCPv6 provides only parameters (DNS, domain), while addresses come from SLAAC. SLAAC uses Router Advertisements for prefix and EUI-64. DHCPv6-PD delegates prefixes. RA Guard prevents rogue RAs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop each DHCPv6 mode on the left to its matching address assignment method on the right.
medium- ✓ P1.Stateful DHCPv6: DHCPv6 server assigns IPv6 addresses and other parameters
- ✓ P2.Stateless DHCPv6: DHCPv6 server provides only options (e.g., DNS), addresses via SLAAC
- ✓ P3.SLAAC: Host generates its own IPv6 address using router advertisements
- ✓ P4.DHCPv6-PD: DHCPv6 prefix delegation for assigning subnets
- ✓ P5.RA: Router Advertisement used in SLAAC to convey prefix and other info
Why P1: Stateful DHCPv6 assigns addresses from a server; stateless DHCPv6 provides other config info but uses SLAAC for addressing; SLAAC uses router advertisements for address autoconfiguration.
