Task
Install Argo CD in the cluster by performing the following tasks:
Add the official Argo CD Helm repository with the name argo
The Argo CD CRDs have already been pre-installed in the cluster
Generate a template of the Argo CD Helm chart version 7.7.3 for the argocd namespace and save it to ~/argo- helm.yaml . Configure the chart to not install CRDs.

Answer:

Task Summary
* SSH into cka000060
* Add the Argo CD Helm repo named argo
* Generate a manifest (~/argo-helm.yaml) for Argo CD version 7.7.3
* Target namespace: argocd
* Do not install CRDs
* Just generate, don't install
# Step-by-Step Solution
1## SSH into the correct host
ssh cka000060
## Required - skipping this = zero score
2## Add the Argo CD Helm repository
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
# This adds the official Argo Helm chart source.
3## Generate Argo CD Helm chart template (version 7.7.3)
Use the helm template command to generate a manifest and write it to ~/argo-helm.yaml.
helm template argocd argo/argo-cd
--version 7.7.3
--namespace argocd
--set crds.install=false
> ~/argo-helm.yaml
* argocd # Release name (can be anything; here it's same as the namespace)
* --set crds.install=false # Disables CRD installation
* > ~/argo-helm.yaml # Save to required file
# 4## Verify the generated file (optional but smart)
head ~/argo-helm.yaml
Check that it contains valid Kubernetes YAML and does not include CRDs.
# Final Command Summary
ssh cka000060
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
helm template argocd argo/argo-cd
--version 7.7.3

NEW QUESTION # 54
What are the differences between using a service versus using an application for Security Policy match?

A. Use of a "service" enables the firewall to take immediate action with the first observed packet based on port numbers. Use of an application allows the firewall to take action after enough packets allow for App-ID identification regardless of the ports being used
B. Use of a "service" enables the firewall to take immediate action with the first observed packet based on port numbers. Use of an "application allows the firewall to take immediate action if the port being used is a member of the application standard port list
C. Use of a "service" enables the firewall to take action after enough packets allow for App-ID identification
