Quick Answer
The correct answer is that the DHCP database is stored in flash and is functioning correctly. This is confirmed by the output of the show ip dhcp database command, which reveals the URL points to flash:/dhcpdb with read/write access, and the status line shows "Last read succeeded" with a write scheduled immediately. The DHCP database status indicates the router can successfully read and write DHCP bindings to flash memory, which is the default persistent storage location for DHCP database persistence on Cisco IOS devices. For the Cisco CCNP ENARSI 300-410 exam, this command tests your understanding of DHCP database storage and troubleshooting; a common trap is assuming a "scheduled write" implies a problem, when in fact it confirms normal operation. Remember the memory tip: "Read succeeded, write queued" means the database is healthy and ready to update.
This 300-410 practice question tests your understanding of dhcp (ipv4 and ipv6). Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
A network engineer runs the following command on Router R1:
R1# show ip dhcp database
URL : flash:/dhcpdb Read/write : Read/Write Last updated : Mar 01 2020 00:00:00 Status : Last read succeeded. Next write scheduled in 0 seconds.
Based on this output, which statement is correct?
The DHCP database is stored in NVRAM and is read-only.
Why wrong: It is stored in flash and is read/write.
The DHCP database is stored in flash and is functioning correctly.
The status shows success.
The DHCP database write failed and needs to be rescheduled.
Why wrong: The last read succeeded.
The DHCP database is empty because no bindings exist.
Why wrong: The output does not indicate emptiness.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The DHCP database is stored in flash and is functioning correctly.
The output shows the DHCP database is stored in flash (URL: flash:/dhcpdb) with read/write access, and the status indicates the last read succeeded with a write scheduled in 0 seconds. This confirms the database is functioning correctly, as the router can read and write DHCP bindings to flash memory, which is the default storage location for DHCP database persistence.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
The DHCP database is stored in NVRAM and is read-only.
Why it's wrong here
It is stored in flash and is read/write.
The DHCP database is stored in flash and is functioning correctly.
Why this is correct
The status shows success.
Related concept
Read the scenario before looking for a memorised answer.
The DHCP database write failed and needs to be rescheduled.
Why it's wrong here
The last read succeeded.
The DHCP database is empty because no bindings exist.
Why it's wrong here
The output does not indicate emptiness.
Common exam traps
Cisco often tests the distinction between DHCP database storage locations (flash vs. NVRAM vs. TFTP) and the interpretation of status messages like 'Last read succeeded' versus 'Last write failed', tricking candidates into assuming a failure or empty database without reading the full output.
Trap categories for this question
Command / output trap
The output does not indicate emptiness.
Detailed technical explanation
The DHCP database stores bindings (IP-to-MAC mappings) to survive a router reload; by default, Cisco IOS uses flash memory for this purpose, but the location can be changed with the 'ip dhcp database' command. The 'Next write scheduled in 0 seconds' indicates the router is ready to write any new bindings immediately, as DHCP bindings are written to the database periodically (default every 10 minutes) or when the lease database changes. In real-world scenarios, if flash becomes full or corrupted, the router may fail to write, leading to loss of DHCP bindings after a reboot.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 300-410 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.
