300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ipv6 dhcp interface GigabitEthernet0/1
GigabitEthernet0/1 is in server mode Using pool: POOL6 Preference value: 0 Hint from client: ignored Rapid-Commit: disabled
Based on this output, which statement is correct?
⚠ Common exam trap
Cisco often tests the ability to read the exact output of 'show ipv6 dhcp interface' and distinguish between server, client, and relay modes, where candidates may misinterpret 'server mode' as client mode or overlook the 'Rapid-Commit: disabled' line.
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 interface is configured as a DHCPv6 server using pool POOL6.
The command output explicitly states 'GigabitEthernet0/1 is in server mode' and 'Using pool: POOL6', which confirms that the interface is acting as a DHCPv6 server. The DHCPv6 server assigns IPv6 addresses and other configuration parameters from the specified pool to requesting clients.
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 interface is configured as a DHCPv6 client.
Why it's wrong here
The output explicitly states the interface is in server mode with a pool assigned, so it cannot be a client. It is tempting because DHCPv6 clients also reference pools indirectly, but client mode would show a client configuration and server address, not 'Using pool: POOL6'.
- ✓
The interface is configured as a DHCPv6 server using pool POOL6.
Why this is correct
The output explicitly states "GigabitEthernet0/1 is in server mode" and "Using pool: POOL6", confirming the interface operates as a DHCPv6 server bound to that pool. This directly satisfies the stem's requirement to identify the interface's DHCPv6 role and its assigned address pool.
- ✗
The interface is using rapid-commit for faster address assignment.
Why it's wrong here
The output states 'Rapid-Commit: disabled', directly contradicting this option. It is tempting because rapid-commit is a real DHCPv6 feature for two-message address assignment, but the interface clearly has it turned off, so it is not in use here.
- ✗
The interface is in DHCPv6 relay mode.
Why it's wrong here
The output states the interface is in server mode, not relay mode. It is tempting because relay agents also reference pools and forward DHCPv6 messages, but a relay would show 'relay mode' and destination addresses rather than 'Using pool: POOL6' with a preference value.
