300-410 Practice Question: Runs the following command to verify DHCPv4…

A network engineer runs the following command to verify DHCPv4 server bindings on router R1:

R1# show ip dhcp binding

Output: Bindings from all pools not associated with VRF:

IP address       Client-ID/              Lease expiration        Type

Hardware address/ User name

192.168.1.10     0050.7966.6800           Mar 01 2025 12:00 PM   Automatic
 192.168.1.11     0063.6973.636f.2d30      Mar 01 2025 01:00 PM   Automatic
 192.168.1.12     0100.1a.2b.3c.4d.5e     Mar 01 2025 02:00 PM   Automatic

What does this output indicate?

⚠ Common exam trap

Cisco often tests the distinction between 'Automatic' (dynamic) and 'Static' (manual) bindings in the DHCP binding table, leading candidates to mistakenly think all bindings are static when they see client IDs that look like MAC addresses.

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 server has dynamically assigned three IP addresses to clients.

The output shows three DHCP bindings with a 'Type' of 'Automatic', which indicates that the IP addresses were dynamically assigned by the DHCP server based on the pool configuration. The 'Client-ID' field contains the MAC address or client identifier provided by the client during the DORA process, confirming dynamic allocation rather than static mapping.

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 server has three static bindings configured.

    Why it's wrong here

    The type is 'Automatic', indicating dynamic assignments, not static.

  • The DHCP server has dynamically assigned three IP addresses to clients.

    Why this is correct

    Each entry shows an IP address, client identifier, lease expiration, and type 'Automatic', confirming dynamic assignments.

  • The DHCP server is out of IP addresses because all bindings are in use.

    Why it's wrong here

    The output only shows three bindings; it does not indicate whether the pool is exhausted.

  • The DHCP server is using relay agents because the client IDs are long hexadecimal strings.

    Why it's wrong here

    Client IDs can include MAC addresses or relay-agent IDs, but this does not necessarily indicate relay agents are in use.
