CKA 2025 MOCK Q -11 TLS

  You’re managing a web server running in a Kubernetes Deployment called secure-site , located in the web-zone namespace. Its NGINX configuration comes from a ConfigMap called site-tls-config . 🧩 Task: Update the ConfigMap ( site-tls-config ) to ensure that only TLS version 1.3 is accepted by the server. Older versions like TLS 1.2 should be blocked completely. Once the ConfigMap is updated: Make sure the secure-site deployment picks up the changes. You might need to restart or roll it out again. Test it with this command: curl --tls-max 1.2 -k https://neokloud.in:32443 The command should fail , because the server should now reject anything below TLSv1.3.   echo "[1/8] Creating namespace: web-zone" kubectl create ns web-zone || true echo "[2/8] Generating TLS certificate for neokloud.in" mkdir -p /tmp/tls && cd /tmp/tls openssl req -x509 -nodes -days 365 \   -newkey rsa:2048 \   -keyout tls.key \   -out tls.crt \   -su...

CKA 2025 MOCK Q-05 HPA

5 Mock Questions on Horizontal Pod Autoscaler (HPA) 🔶 Question 1: Scale Based on Custom CPU Target and Scale-Up Cooldown You have a Deployment named api-backend in the default namespace. Task: Create an HPA targeting 70% CPU usage Min: 1, Max: 10 replicas Set scale-up cooldown (delay before scaling up again) to 30 seconds File name: hpa-backend.yaml Bonus: Set the HPA to avoid scaling up rapidly even if CPU spikes.   cat <<EOF | kubectl apply -f - apiVersion: apps/v1 kind: Deployment metadata:   name: api-backend   namespace: default spec:   replicas: 2   selector:     matchLabels:       app: api-backend   template:     metadata:       labels:         app: api-backend     spec:       containers:   ...
