Quick Answer
The answer is top, as it is the command that displays current running processes in real time. Unlike ps, which captures a static snapshot of processes at a single moment, top continuously refreshes its output, showing dynamic updates of CPU and memory usage, process IDs, and resource consumption. On the CompTIA Linux+ XK0-005 exam, this question tests your understanding of process monitoring utilities and their distinct behaviors; a common trap is confusing top with ps, since both list processes, but only top provides live updates. The exam may present scenarios where you need to identify a tool for ongoing performance observation, making top the correct choice over htop (an enhanced alternative) or pstree (which shows parent-child relationships). To remember: think of top as the "live dashboard" that keeps scrolling, while ps is a "photograph" of a single moment.
This XK0-005 practice question tests your understanding of scripting, containers and automation. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 command will show the current running processes in real time?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
top
top continuously updates the list of processes.
pstree
Why wrong: pstree displays processes in a tree hierarchy, not real-time updates.
ps aux
Why wrong: ps aux shows a static snapshot of processes, not real-time.
htop
Why wrong: htop is also real-time but is an alternative, not the standard command.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
top
top provides a real-time view of running processes. ps gives a snapshot, htop is an alternative, and pstree shows a process tree.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
top
Why this is correct
top continuously updates the list of processes.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
pstree
Why it's wrong here
pstree displays processes in a tree hierarchy, not real-time updates.
ps aux
Why it's wrong here
ps aux shows a static snapshot of processes, not real-time.
htop
Why it's wrong here
htop is also real-time but is an alternative, not the standard command.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
ps aux shows a static snapshot of processes, not real-time.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related XK0-005 NAT questions on configuration and troubleshooting.
