CKA受験前に知っておきたいQ&A

Linux Foundation Certified Kubernetes Administrator (CKA) Program 認定 CKA 試験問題：

問題 #1

For this item, you will have to ssh to the nodes ik8s-master-0 and ik8s-node-0 and complete all tasks on these nodes. Ensure that you return to the base node (hostname: node-1) when you have completed this item.
Context
As an administrator of a small development team, you have been asked to set up a Kubernetes cluster to test the viability of a new application.
Task
You must use kubeadm to perform this task. Any kubeadm invocations will require the use of the --ignore- preflight-errors=all option.
* Configure the node ik8s-master-O as a master node. .
* Join the node ik8s-node-o to the cluster.

問題 #2

Task
Create a new Ingress resource as follows:
. Name: echo
. Namespace : sound-repeater
. Exposing Service echoserver-service on
http://example.org/echo
using Service port 8080
The availability of Service
echoserver-service can be checked
i
using the following command, which should return 200 :
[candidate@cka000024] $ curl -o /de v/null -s -w "%{http_code}\n"
http://example.org/echo

問題 #3

Given a partially-functioning Kubernetes cluster, identify symptoms of failure on the cluster.
Determine the node, the failing service, and take actions to bring up the failed service and restore the health of the cluster. Ensure that any changes are made permanently.
You can ssh to the relevant I nodes (bk8s-master-0 or bk8s-node-0) using:
[student@node-1] $ ssh <nodename>
You can assume elevated privileges on any node in the cluster with the following command:
[student@nodename] $ | sudo -i

問題 #4

Create a deployment as follows:
* Name: nginx-random
* Exposed via a service nginx-random
* Ensure that the service and pod are accessible via their respective DNS records
* The container(s) within any pod(s) running as a part of this deployment should use the nginx Image Next, use the utility nslookup to look up the DNS records of the service and pod and write the output to /opt
/KUNW00601/service.dns and /opt/KUNW00601/pod.dns respectively.

問題 #5

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
