LPIC-2 Advanced Networking Configuration Practice Question
This LPIC-2 practice question tests your understanding of advanced networking configuration. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An administrator needs to add a static route to the destination network 192.168.100.0/24 via gateway 10.0.0.1. Which TWO of the following commands accomplish this? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ip route add 192.168.100.0/24 via 10.0.0.1
Option A is correct because the `ip route add` command is the modern Linux utility for adding static routes, specifying the destination network and gateway via the `via` keyword. Option E is correct because the legacy `route add -net` command also adds a static route, using the `gw` parameter to define the gateway, and both commands achieve the same result of adding a route to 192.168.100.0/24 via 10.0.0.1.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse adding a static route with adding an IP address to an interface (Option C) or with a firewall rule (Option D), and they may overlook that `nmcli` requires an additional activation step to apply the route immediately.
Trap categories for this question
Keyword trap
The nmcli syntax for adding a route requires the 'via' keyword or different format.
Detailed technical explanation
How to think about this question
Under the hood, both `ip route add` and `route add` modify the kernel's routing table (FIB), which the kernel uses to determine the next hop for outbound packets. The `ip` command from the iproute2 suite is the modern replacement for the deprecated `route` command, and it supports more advanced features like multiple routing tables, nexthop objects, and policy routing. In real-world scenarios, using `nmcli` for persistent routes is common in NetworkManager-managed systems, but the question asks for immediate addition, making `ip route` and `route` the correct choices.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
