Splunk Interview Questions (8+ Questions)

System resources are being consumed by unusually large process. We need to identify parent process that has most children. For that we can use pstree command because Linux provides the pstree command to display hierarchical process tree, including processes and command arguments. We need to write everything in the process tree report TXT file. We can get process IDs and arguments by adding those two flags. We have a lot of children processes under this process, and it has ID 189. Isolate only this by typing pstree -p 189.

We have a pipeline with three jobs, lint, test, and build. The problem is all the three run in parallel with no ordering, which means that the build could succeed even if linting or testing failed. What we need to do over here is to enforce a strict sequence, which would be lint first, then test, and finally build. By default, jobs in a GitHub Actions workflow run in parallel, which means at the same time. So they start at the same time and don't wait for each other, and the needs keyword over here is what changes that. So what is different is that job B needs job A, that job B won't start until and unless job A has completed successfully. And if job A, for whatever reason, fails, then job B is completely skipped entirely, and this is how we enforce ordering between jobs. We can create a chain where each job depends on the one before it. Since dependency is transitive, we can have C to be dependent on B only. We can write something like needs lint and test, to make a job which will wait for both the lint and test to complete.

def is_valid(s: str) -> bool:
stack = []
close_to_open = {")": "(", "]": "[", "}": "{"}

for c in s:
    if c in close_to_open:
        if stack and stack[-1] == close_to_open[c]:
            stack.pop()
        else:
            return False
    else:
        stack.append(c)
        
return True if not stack else False
