LPIC-2 Network Client Management Practice Question
Exhibit
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.100 192.168.1.200;
}
subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.100 192.168.2.200;
}
host special {
hardware ethernet 08:00:27:ab:cd:ef;
fixed-address 192.168.2.10;
}Refer to the exhibit. A client with MAC address 08:00:27:ab:cd:ef on the 192.168.1.0/24 network receives IP 192.168.2.10 instead of an IP from the 192.168.1.0 subnet. What is the most likely explanation?
⚠ Common exam trap
Test-takers frequently assume a relay agent or client misconfiguration is responsible, but the real issue is the DHCP server's host declaration overriding subnet pool selection with a fixed-address from a different subnet.
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 server's host declaration assigns a fixed-address from a different subnet.
The DHCP server's host declaration explicitly assigns a fixed-address to the client's MAC address (08:00:27:ab:cd:ef) from a different subnet (192.168.2.10). In ISC DHCP, the 'host' block with a 'fixed-address' directive overrides any subnet pool selection, forcing the server to offer that specific IP regardless of the relay agent or client's subnet. This is a common misconfiguration when administrators copy host declarations between subnet definitions without updating the address.
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 relay agent is misconfigured and forwards requests to the wrong subnet.
Why it's wrong here
Incorrect. The relay agent would affect which subnet pool is used, but the fixed-address host entry takes precedence regardless.
- ✗
The client's network interface is set to a static IP address.
Why it's wrong here
Incorrect. If the client had a static IP, it would not send DHCP requests; dynamic assignment would not occur.
- ✓
The server's host declaration assigns a fixed-address from a different subnet.
Why this is correct
Correct. The host entry for the client's MAC assigns an IP from 192.168.2.0, overriding the subnet automation.
- ✗
The client sent a DHCP request with an incorrect subnet mask.
Why it's wrong here
Incorrect. The client's subnet mask does not affect which IP the server assigns; the server uses its configuration.
