How to: Environment setup
As soon as your exam starts, you will want to setup `kubectl` and your chosen text editor as follows:

1. Setup `kubectl`
   ```sh
   alias k=kubectl # this is usually preconfigured in exam
   export dr="--dry-run=client -oyaml"
   ```
2. Setup text editor
   ```sh
   # vim
   printf "set tabstop=2\nset shiftwidth=2\nset expandtab" > ~/.vimrc
   # nano
   printf "set tabsize 2\nset tabstospaces" > ~/.nanorc
   ```

Questions use different Clusters and different Namespaces. Therefore, for each question:

1. Make sure you always run the command to switch to the Cluster for that question - command will be provided
2. Create a variable for the question's Namespace `ns=$QUESTION_NAMESPACE` to make things easy for yourself
3. Do not assume the default Namespace is `default`, always set and use your variable `ns=default`

```sh
