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.
Which of the following commands creates a new network namespace named 'test'?
netns add test
Why wrong: The full command is 'ip netns add'.
network namespace add test
Why wrong: No such command exists.
ip netns add test
This is the correct syntax to create a new network namespace.
ip netns create test
Why wrong: The verb is 'add', not 'create'.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ip netns add test
The correct command to create a new network namespace named 'test' is 'ip netns add test'. The 'ip netns' command is part of the iproute2 suite and is the standard tool for managing network namespaces in Linux. The 'add' subcommand creates a new namespace by binding it to a mount point under /var/run/netns/.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
netns add test
Why it's wrong here
The full command is 'ip netns add'.
network namespace add test
Why it's wrong here
No such command exists.
ip netns add test
Why this is correct
This is the correct syntax to create a new network namespace.

ip netns create test
Why it's wrong here
The verb is 'add', not 'create'.
Common exam traps
The trap here is that candidates may confuse the 'ip netns' subcommands, incorrectly using 'create' instead of 'add', or omitting the 'ip' prefix, because they are misled by the generic verb 'create' or the phrase 'network namespace' from other contexts like Docker or systemd-nspawn.
Trap categories for this question
Command / output trap
The full command is 'ip netns add'.
Detailed technical explanation
Network namespaces provide isolated network stacks, including separate interfaces, routing tables, and firewall rules. When 'ip netns add test' is executed, it creates a bind mount of /proc/1/ns/net to /var/run/netns/test, allowing processes to be attached to the namespace via 'ip netns exec'. This is fundamental for container networking, where each container typically runs in its own namespace to achieve isolation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the LPIC-2 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
