Actual exam question for Linux Foundation's CKS exam

Question #: 62
Topic #: 5

Two tools are pre-installed on the cluster's worker node:

Using the tool of your choice (including any non pre-installed tool), analyze the container's behavior for at least 30 seconds, using filters that detect newly spawning and executing processes.

Store an incident file at /opt/KSRS00101/alerts/details, containing the detected incidents, one per line, in the following format:

Just use `ps` and `grep` to find new processes.

I feel confident about detecting processes, but I’m a bit unsure about the exact path for storing the incident file. Was it `/opt/KSRS00101/alerts/details`?

The incident file format looks familiar, but I might mix up the order of the fields. I should double-check that before submitting.

I think we also discussed using `ps` with specific flags to track new processes. I hope I can recall those flags during the exam.

I remember we practiced using `strace` to monitor process creation, but I'm not entirely sure how to filter the output correctly.

This seems straightforward enough. I'll just use `ps` or `top` to monitor the container, and then format the output to match the example.

Okay, I've got a plan - I'll use a tool like `strace` or `ltrace` to monitor the container's behavior, and then parse the output to extract the relevant details in the required format.

Easy peasy! The question clearly states that the Huawei 1288H V5 supports up to two high-performance GPUs, so the answer must be TRUE.

This question is making me hungry. I wonder if there's a tool that can analyze the behavior of a hot dog while it's being cooked. Now that would be a useful skill!

Wait, we're supposed to use a non-pre-installed tool? I bet the exam writers are just trying to trick us. I'm sticking with one of the pre-installed options, no matter what!

The example incident file looks clear, but I'm not sure which tool to use. I guess I'll need to experiment with the pre-installed tools to see which one works best.

This question seems straightforward, but the details about the incident file format are a bit confusing. I'll need to read it carefully a few times to make sure I understand.
