CKAD Practice Question: Application Environment, Configuration and Security
This CKAD practice question tests your understanding of application environment, configuration and security. 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.
A developer creates a Role and RoleBinding in the namespace 'development' to grant list pods permission to a service account. Which manifest snippet correctly defines the Role?
Option C is correct because pods belong to the core API group, which is represented by an empty string `""` in the `apiGroups` field. The `list` verb is sufficient to list pods, and the `resources` field correctly specifies `pods`. This Role grants the service account permission to list pods in the `development` namespace.
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.
apiGroups: ["*"] is not correct; use "" for core group.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the core API group with a named group like `"apps"` or use a wildcard `"*"` instead of the correct empty string `""`, leading to rules that either don't apply or are overly permissive.
Detailed technical explanation
How to think about this question
In Kubernetes RBAC, the `apiGroups` field must match the API group of the resource. For core resources like pods, services, and namespaces, the API group is an empty string `""`, not `"v1"` or `"core"`. The `verbs` field supports standard HTTP verbs like `get`, `list`, `watch`, `create`, `update`, `patch`, and `delete`; `list` alone is sufficient for listing pods but does not grant `get` for individual pods. A common real-world scenario is granting a monitoring service account only `list` and `watch` permissions to avoid exposing sensitive pod details via `get`.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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 practitioner preparing for the CKAD exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

What is the correct answer to this question?
The correct answer is: rules:
- apiGroups: [""]
resources: ["pods"]
verbs: ["list"] — Option C is correct because pods belong to the core API group, which is represented by an empty string `""` in the `apiGroups` field. The `list` verb is sufficient to list pods, and the `resources` field correctly specifies `pods`. This Role grants the service account permission to list pods in the `development` namespace.
