CKA 2025 MOCK Q-05 HPA

 
In the exam, you need to maintain a rhythmic speed—that means working fast without wasting steps.
You’ll have to use shortcuts smartly and avoid repeating the same command unnecessarily.

These next 5 minutes could make a huge difference in your exam, so let’s begin.

Many people recommend using imperative commands in Kubernetes — like kubectl run or kubectl expose.
While these can be useful for quickly creating a Pod, I personally recommend:

Use imperative only for Pod creation, but for everything else — avoid it.

Why?

Because in the real world and exams, what really helps is:

• Knowing how to find the correct YAML

• Editing and understanding it properly

• Applying declarative files using kubectl apply -f

So instead of relying on imperative commands, get comfortable with:

• The official Kubernetes documentation

• Using Ctrl + F + apiVersion to jump straight to YAML examples

• The Kubernetes cheat sheet (we’ll cover that too)

Mastering how to quickly locate or build YAML files will help you more than memorizing one-liners.

We'll go through this in detail — including tricks to grab YAMLs fast, without scrolling, and how to tweak them for your exam.

Pro Tips

• If you're in a hurry, search the word apiVersion — 99% chance it’s just above the YAML block.
  (you should create your own thing so better practice whatever you use)

• Kubernetes rarely gives external .yaml files — most YAMLs are inline on the doc page.

vi Shortcut

Delete Word(s) in Vim

Command	What It Does
dw	Delete from cursor to end of word
daw	Delete entire word under cursor (including space)
diw	Delete inner word (just the word, no space)
d2w	Delete 2 words from cursor
dW	Delete until end of word (big word — space-separated, not punctuation-based)

Delete Line(s)

Command	What It Does
dd	Delete the entire current line
2dd	Delete 2 lines starting from current line
d$	Delete from cursor to end of line
D	Same as d$ (shorthand)
d0	Delete from cursor to start of line
:1,5d	Delete lines from line 1 to 5
:.,+3d	Delete current line and next 3 lines

Delete Inside or Around Text Objects

Command	What It Does
di"	Delete text inside double quotes
da"	Delete text around double quotes (including quotes)
di( or di)	Delete inside parentheses
da( or da)	Delete around parentheses, including them

Tips for Fast Practice

• You must be in normal mode (press Esc first).

• Use u to undo a delete (very handy).

• Use . to repeat the last delete (super fast for repeated actions).

• Use line numbers with :n commands for bulk deletions.
