Quick Answer
The correct configuration order for DHCP pool and relay agent begins with defining the DHCP pool and network, then setting the default router and DNS server, followed by excluding addresses, and finally enabling the relay agent on the client-facing interface, with verification of bindings and statistics as the last step. This sequence is technically necessary because the DHCP pool must be created and its parameters established before you can exclude specific addresses from that pool, and the relay agent configuration depends on the interface being ready to forward client broadcasts to the server. On the Cisco CCNP ENARSI 300-410 exam, this drag-and-drop task tests your understanding of the logical dependency between DHCP server configuration and relay functionality, often trapping candidates who mistakenly place address exclusion before defining the pool or who enable the relay agent before the pool is fully configured. A common memory tip is to think of building the house before installing the doorbell: the pool is the house, exclusions are the locked doors, and the relay agent is the doorbell that forwards requests. Remember the mnemonic "Pool, Router, Exclude, Relay" to lock in the correct order.
300-410 DHCP (IPv4 and IPv6) Practice Question
This 300-410 practice question tests your understanding of dhcp (ipv4 and ipv6). This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Correct answer & explanation
✓
Configure DHCP pool with network and mask
First, you must define the DHCP pool with a name and network. Then, you set the default router and DNS server. Next, you exclude any addresses from the pool. Finally, you enable the DHCP relay agent on the interface facing clients to forward requests to the DHCP server.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 300-410 subnetting questions on CIDR, address ranges, and subnet selection.
