LPIC-2 Advanced Networking Configuration Practice Question
This LPIC-2 practice question tests your understanding of advanced networking configuration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Exhibit
Refer to the exhibit.
Output of 'ip route show' on a Linux router:
default via 10.0.0.1 dev eth0 metric 100
10.0.0.0/24 dev eth0 proto kernel scope link src 10.0.0.2 metric 100
192.168.1.0/24 via 10.0.0.254 dev eth0 metric 50
192.168.2.0/24 dev eth1 proto kernel scope link src 192.168.2.1 metric 100
A packet destined to 192.168.1.100 is sent from this router. Which interface will be used to forward it?

A
eth0
The route to 192.168.1.0/24 uses eth0.
B
lo
Why wrong: Destination is not a local address.
C
eth1
Why wrong: There is no route for 192.168.1.0/24 via eth1.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
eth0
The router uses the routing table to determine the next hop for a packet destined to 192.168.1.100. Assuming a directly connected subnet (e.g., 192.168.1.0/24) is associated with eth0, the kernel will match the longest prefix and forward the packet out of eth0. This is standard IP forwarding behavior governed by the routing table (e.g., 'ip route show').
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

lo
Why it's wrong here
Destination is not a local address.
✗
eth1
Why it's wrong here

Why it's wrong here
A valid route exists via eth0.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the router will use the interface with the same IP subnet as the destination, but they forget to verify that the routing table actually contains a directly connected route for that subnet; without a matching route, the packet would be dropped or forwarded via a default route.
Detailed technical explanation
How to think about this question
Under the hood, the Linux kernel performs a routing lookup using the FIB (Forwarding Information Base), which is built from the routing table. The 'ip route get 192.168.1.100' command can be used to simulate the exact interface and next hop the kernel would choose. In real-world scenarios, misconfigured routing tables (e.g., missing default gateway or overlapping subnets) can cause packets to be sent out the wrong interface or silently dropped.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

The correct answer is: eth0 — The router uses the routing table to determine the next hop for a packet destined to 192.168.1.100. Assuming a directly connected subnet (e.g., 192.168.1.0/24) is associated with eth0, the kernel will match the longest prefix and forward the packet out of eth0.
