NEW QUESTION # 80
You need to schedule a pod to run only on nodes that have specific hardware resources, such as a certain amount of memory or a particular GPU type. Explain how you can use node affinity to achieve this.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Node Affinity: Add an 'affinity' section to the 'spec.template.spec' section of your pod definition YAML file.

2. Set 'nodeSelectorTerms': In the 'nodeAffinity' section, specify requiredDuringSchedulinglgnoredDuringExecutioru to indicate that the node affinity rule must be met during pod scheduling. Within 'nodeSelectorTerms' , use 'matchExpressions' to match the node label 'kubernetes.io/hostname' to the value 'my-gpu-node'. Replace "my-gpu-node" with the actual hostname of the node that has the required resources. 3. Apply the Pod: Apply the YAML file to your cluster using 'kubectl apply -f my-resource-intensive-pod.yaml' Kubernetes will attempt to schedule the pod only on the node labeled 'my-gpu-node'. If the node is unavailable or if no nodes have the required labels, the pod will remain in a pending state until a suitable node becomes available.

NEW QUESTION # 82
You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000051
Context
You manage a WordPress application. Some Pods are not starting because resource requests are too high.
Your task Is to prepare a Linux system for Kubernetes . Docker is already installed, but you need to configure it for kubeadm .
Task
Complete these tasks to prepare the system for Kubernetes :
Set up cri-dockerd :
. Install the Debian package
~/cri-dockerd_0.3.9.3-0.ubuntu-jammy_am
d64.deb
Debian packages are installed using
dpkg .
. Enable and start the cri-docker service
Configure these system parameters:
. Set net.bridge.bridge-nf-call-iptables to 1

Answer:

Explanation:
Task Summary
You are given a host to prepare for Kubernetes:
* Use dpkg to install cri-dockerd
* Enable and start the cri-docker service
* Set net.bridge.bridge-nf-call-iptables to 1 via sysctl
Step-by-Step Instructions
1## SSH into the correct node
bash
CopyEdit
ssh cka000051
## Required - failure to connect to the correct host = zero score.
2## Install cri-dockerd
You are told the .deb file is already located at:
bash
CopyEdit
~/cri-dockerd_0.3.9.3-0.ubuntu-jammy_amd64.deb
Install it with dpkg:
bash
CopyEdit
sudo dpkg -i ~/cri-dockerd_0.3.9.3-0.ubuntu-jammy_amd64.deb
# If any dependencies are missing (e.g., golang or containerd), you might need:
bash
CopyEdit
sudo apt-get install -f -y
But usually, the exam system provides a pre-validated .deb environment.
3## Enable and start cri-docker service
Start and enable both services:
bash
CopyEdit
sudo systemctl enable cri-docker.service
sudo systemctl enable --now cri-docker.socket
sudo systemctl start cri-docker.service
Check status (optional but smart):
bash
CopyEdit
sudo systemctl status cri-docker.service
You should see it active (running).
4## Configure the sysctl parameter
Set net.bridge.bridge-nf-call-iptables=1 immediately and persistently.
Step A: Apply immediately:
sudo sysctl net.bridge.bridge-nf-call-iptables=1
Step B: Persist it in /etc/sysctl.d:
Create or modify a file:
echo "net.bridge.bridge-nf-call-iptables = 1" | sudo tee /etc/sysctl.d/k8s.conf Reload sysctl:
sudo sysctl --system
Verify:
sysctl net.bridge.bridge-nf-call-iptables
Should return:
net.bridge.bridge-nf-call-iptables = 1
# Now the system is ready for kubeadm with Docker (via cri-dockerd)!
ssh cka000051
sudo dpkg -i ~/cri-dockerd_0.3.9.3-0.ubuntu-jammy_amd64.deb
sudo systemctl enable cri-docker.service
sudo systemctl enable --now cri-docker.socket
sudo systemctl start cri-docker.service
sudo sysctl net.bridge.bridge-nf-call-iptables=1
echo "net.bridge.bridge-nf-call-iptables = 1" | sudo tee /etc/sysctl.d/k8s.conf sudo sysctl --system
