300-410 Practice Question: Runs the following command to verify DHCPv4 pool…
A network engineer runs the following command to verify DHCPv4 pool configuration on router R1:
R1# show ip dhcp pool DHCP_POOL
Output: Pool DHCP_POOL : Utilization mark (high/low) : 100 / 0 Subnet size (first/next) : 0 / 0 Total addresses : 254 Leased addresses : 100 Pending event : none 1 subnet is currently in the pool : Current index IP address range Leased addresses
192.168.1.1 192.168.1.1 - 192.168.1.254 100
What does this output indicate?
⚠ Common exam trap
Cisco often tests the distinction between the 'Utilization mark' (a configurable threshold for alerts) and actual pool utilization, causing candidates to misinterpret the 100% high mark as meaning the pool is full.
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 DHCP pool has 254 addresses available, and 100 are currently leased.
The output shows 'Total addresses: 254' and 'Leased addresses: 100', meaning the pool contains 254 total addresses (the /24 subnet) and 100 are currently leased, leaving 154 available. The 'Utilization mark (high/low): 100 / 0' indicates the thresholds for alerts, not actual usage, and the pool is not exhausted.
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 DHCP pool has 254 addresses available, and 100 are currently leased.
Why this is correct
The pool spans 192.168.1.1–192.168.1.254, giving 254 usable host addresses, of which 100 are leased. This directly satisfies the stem's request to interpret the "Total addresses" and "Leased addresses" counters, confirming current utilisation without indicating exhaustion or conflict.
- ✗
The DHCP pool is exhausted because 100 addresses are leased.
Why it's wrong here
100 leased addresses out of 254 total leaves 154 available, so the pool is not exhausted. Exhaustion would show leased addresses equal to total addresses with a pending event; the utilisation mark of 100/0 is a threshold setting, not current usage.
- ✗
The DHCP server is using a database agent to store leases.
Why it's wrong here
The output shows only pool parameters and lease counts; a database agent would appear as an explicit 'Database agent' or 'Database :' line with its IP address. It is tempting because database agents do persist bindings across reloads, but that is configured separately with 'database url', not evidenced by this utilisation output.
- ✗
The DHCP pool has a utilization mark of 100%, meaning it is full.
Why it's wrong here
The 100/0 line is the high/low utilisation threshold for logging, not current usage; 100 of 254 addresses are leased, so the pool is not full. Confusing the threshold with actual utilisation is tempting, but the 'Leased addresses' and 'Current index' fields give the real occupancy.
