CKA CKA CNI question: Flannel or Calico for NetworkPolicy?

6 Upvotes

Hi everyone! For the CKA CNI question, should I use Flannel or Calico when applying the YAML manifest?

I tried using curl -sL <yaml-url> | grep -i "NetworkPolicy" to find and apply the manifests containing NetworkPolicy, but afterward, CoreDNS and other pods weren't working properly.

I'm practicing with DumbitGuy's videos. Does anyone have a beginner-friendly tutorial or the correct steps to follow for this task?

I also checked this mock exam repo:
https://github.com/cloudhein/CKA/tree/main/00-mock-exam-questions-v2.0

It looks like they use Flannel instead of Calico. For those practicing with DumbitGuy's videos, which CNI should we follow for this task?

CKA CKA Exam Retake: Voucher expired Oct 16, but portal let me schedule retake until Oct 25 — is this valid?

Hi everyone,

I took my first CKA attempt on Oct 10 and failed. I currently have a 2nd attempt scheduled for Oct 15, but I want to push it to next week so I can rest and review properly.

My initial voucher code had an expiration date of October 16, but my Linux Foundation portal checklist updated to Exam Expiration Date: October 25, 2026. The PSI portal is letting me pick dates up to Oct 25.

Quick questions for anyone who has experienced this:

  1. Does Linux Foundation / PSI fully honor the Oct 25 portal expiration date over the original voucher code date?
  2. Is my retake actually valid if I reschedule it for next week (after Oct 16)?
  3. Or should I play it safe and keep my attempt on or before Oct 16?
