I prefer using `kubectl logs --tail` for better control.

Yup, that will capture all logs with 'started'.

I think you need to use `-f` for follow mode.

I think the pattern search is case-insensitive with "-i", but I need to double-check if I need quotes around "started".

I believe the output redirection to the file is done with ">", but I might be mixing it up with another command.

I remember practicing a similar question where we had to filter logs, but I can't recall if I used "grep" correctly.

I think the command should start with "kubectl logs" but I'm not sure about the exact syntax for filtering.

I'm pretty confident about this one. I think the correct answer is A - XML doesn't restrict which transmission protocols can be used.

I'm a bit confused by the wording of this question. I'll have to re-read it a few times to make sure I understand what they're asking.

The Goodbye handler doesn't sound like it would announce options at the start, so I'm leaning towards either the Directory or the Operator handler.

I think application whitelisting/blacklisting is definitely the right choice for blocking specific applications, but I'm not totally sure how it works in practice.

I think I've got it! I'll use an accumulator to keep track of the count, and then print out the final value. That way, I don't have to worry about manually incrementing a counter.

Is it just me, or does 'frontend' sound like the name of a superhero sidekick? 'The Mighty Frontend, defender of logs and vanquisher of 'started' patterns!'

This is a straightforward command to get the logs for the 'frontend' pod and search for the 'started' pattern, then write the output to the '/opt/error-logs' file. Easy peasy!

Yes, that's correct. It will search for the 'started' pattern in the logs of the 'frontend' pod and save it to the '/opt/error-logs' file.
