Linux Foundation Certified Kubernetes Administrator (CKA) Program Exam 認定 CKA 試験問題 (Q47-Q52):

質問 # 47
Your team has deployed a containerized application on Kubernetes. You have configured a deployment with a replica count of 3 pods. The application uses a resource-intensive process that consumes a significant amount of CPU resources. You are experiencing performance issues and suspect that the pods are competing for resources. Explain how you can use resource quotas and limits to address this problem.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Resource Limits for Pods:
- Modify the deployment configuration to set resource limits for each pod, specifying the maximum CPU and memory resources they can consume. This prevents pods from exceeding their resource allocations, ensuring fairer resource distribution.

2. Implement Resource Quotas at the Namespace Level: - Define resource quotas for the namespace where your application is running. This limits the overall resource consumption within the namespace, preventing any single pod from monopolizing resources.

3. Monitor Resource Usage and Adjust Limits: - Continuously monitor the resource usage of your pods and the namespace. Analyze the CPU and memory utilization to identify any resource contention. - Adjust resource limits and quotas as needed to fine-tune the resource allocation and improve performance.

質問 # 48
Allow traffic from all the pods in "web" namespace and from pods
with label "type=monitoring" to the pods matching label "app: db"

A. kubectl create namespace web
kubectl label namespace/web app=web

正解：A

質問 # 49
Your team is deploying a critical application on Kubernetes and needs to ensure its availability and performance. You are considering implementing a load balancer for the application to distribute traffic across multiple pods. Describe the types of load balancers available in Kubernetes and explain how to implement an external load balancer using a cloud provider's load balancer service.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Types of Load Balancers in Kubernetes:
- NodePort: A simple load balancer that exposes the service on each node's IP address and a specific port.
- LoadBalancer: Exposes the service on the public IP address of the cloud provider's load balancer.
- Ingress: A higher-level abstraction that allows for more flexible routing and configuration of traffic to services.
2. Implementing an External Load Balancer using a Cloud Provider:
- Create a Kubernetes Service:
- Define a Kubernetes Service that exposes the application on a specific port.
- Configure the service type to 'LoadBalancer'.

- Configure a Cloud Provider Load Balancer: - Access the load balancer management console of your cloud provider (e.g., AWS Elastic Load Balancer, Google Cloud Load Balancing, Azure Load Balancer). - Create a new load balancer and configure it to listen on the desired port (e.g., port 80). - Configure the load balancer to distribute traffic to the Kubernetes service. This might involve specifying the Kubernetes service's IP address or hostname, depending on the cloud provider's setup. - Configure the health check settings to ensure that the load balancer only routes traffic to healthy pods. - Verify Load Balancer Configuration: - Once the cloud provider load balancer is configured, verify that it is working correctly by accessing the load balancer's public IP address and ensuring that the application responds as expected. - You can also use 'kubectl describe service myapp-service' to check the load balancer's status and external IP address. ,

質問 # 50
Change the Image version to 1.15-alpine for the pod you just created and verify the image version is updated.

A. Kubect1 set image pod/nginx nginx=nginx:1.15-alpine
kubect1 describe po nginx
// another way it will open vi editor and change the version
kubeclt edit po nginx
kubect1 describe po nginx
B. Kubect1 set image pod/nginx nginx=nginx:1.15-alpine
kubect1 describe po nginx
// another way it will open vi editor and change the version
kubect1 describe po nginx

正解：A

質問 # 51
You are tasked with setting up a Kubernetes cluster for a company with a strict security policy. They have two different teams: Development and Operations, with distinct access requirements.
The Development team needs read-only access to all resources and the ability to create and manage deployments, pods, and services. The Operations team needs full access to all resources, including cluster management, and the ability to perform actions like scaling, rolling updates, and troubleshooting.
Design a role-based access control (RBAC) configuration using Kubernetes resources (Role, RoleBinding, ClusterRole, ClusterRoleBinding) to grant appropriate access to each team.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
Step 1: Create a Role for the Development team:

Step 2: Create a RoleBinding for the Development team:

Step 3: Create a ClusterRole for the Operations team:

Step 4: Create a ClusterRoleBinding for the Operations team:

The Role for the Development team grants specific permissions to create, manage, and view deployments, pods, and services. It also grants read-only access to all other resources. The RoleBinding links the "dev-role" to the "dev-user" account, allowing them to perform actions as defined by the Role. The ClusterRole for the Operations team provides full access to all cluster resources and allows them to perform any action, including cluster management tasks. The ClusterRoleBinding links the "ops-clusterrole" to the "ops-user" account, granting them complete control over the cluster. Note: You can replace "dev-user" and "ops-user" with actual user names or service accounts.
