300-410 Practice Question: Runs the following command to verify DHCPv6 pool…
A network engineer runs the following command to verify DHCPv6 pool configuration on router R1:
R1# show ipv6 dhcp pool
Output: Pool DHCPv6_POOL : Prefix number: 1 Prefix: 2001:DB8:1::/48 Preferred lifetime 604800, valid lifetime 2592000 Expires at Mar 01 2025 12:00 PM (2592000 seconds) DNS server: 2001:DB8::1 Domain name: example.com Active clients: 5
What does this output indicate?
⚠ Common exam trap
Cisco often tests the distinction between DHCPv6 address assignment and prefix delegation, where candidates mistakenly interpret 'Active clients' as hosts with IPv6 addresses rather than routers that have received delegated prefixes.
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
✓
The DHCPv6 pool has 5 active clients and provides prefix delegation, DNS, and domain name.
The output shows a DHCPv6 pool configured with prefix delegation (2001:DB8:1::/48), DNS server, and domain name, along with 5 active clients. This confirms that the pool is used for stateful DHCPv6 (prefix delegation) and provides additional options, making option A correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The DHCPv6 pool has 5 active clients and provides prefix delegation, DNS, and domain name.
Why this is correct
The output shows a prefix for delegation, DNS server, domain name, and 5 active clients.
- ✗
The DHCPv6 pool is used only for stateless address autoconfiguration (SLAAC).
Why it's wrong here
The pool includes a prefix for delegation, which is used for stateful prefix delegation, not SLAAC.
- ✗
The DHCPv6 pool has 5 clients with addresses from the prefix 2001:DB8:1::/48.
Why it's wrong here
The prefix is for delegation, not for address assignment; the clients may have delegated prefixes.
- ✗
The DHCPv6 pool has a preferred lifetime of 2592000 seconds.
Why it's wrong here
The preferred lifetime is 604800 seconds; the valid lifetime is 2592000 seconds.
