CKA Practice Question: Cluster Architecture, Installation & Configuration
This CKA practice question tests your understanding of cluster architecture, installation & configuration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are valid steps to enable audit logging in a Kubernetes cluster?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an audit policy file defining what events to log.
Option B is correct because audit logging in Kubernetes requires an audit policy file that defines which events (e.g., RequestResponse, Metadata) should be logged. This policy file must be created and then passed to the kube-apiserver via the --audit-policy-file flag. Without a policy file, the apiserver will not know what to log, even if other flags are set.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Store the audit policy in a ConfigMap and reference it via --audit-policy-configmap.
Why it's wrong here
There is no such flag; the policy file is passed directly.
✓
Create an audit policy file defining what events to log.
Why this is correct
The policy file is required.

✓
Add the --audit-log-path flag to the kube-apiserver.
Why this is correct
This flag specifies where to write audit logs.

✗
Restart the kubelet on the control plane node.
Why it's wrong here
The API server is a static pod; the kubelet does not need restart.
✓
Mount the audit policy file into the kube-apiserver container.
Why this is correct
The file must be accessible to the API server.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the --audit-policy-configmap option (which does not exist) with the valid --audit-policy-file flag, or think that restarting the kubelet is necessary for apiserver changes, when in fact the kube-apiserver is a static Pod managed by the kubelet but its configuration is independent.
Detailed technical explanation
How to think about this question
The kube-apiserver reads the audit policy file at startup and applies rules based on stages (e.g., RequestReceived, ResponseComplete) and levels (None, Metadata, Request, RequestResponse). The --audit-log-path flag specifies the output file, and the --audit-log-maxsize flag controls log rotation. In a static Pod setup, the audit policy file must be mounted into the apiserver container via a hostPath volume, as in option E.

Find the constraint that changes the correct option.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
