- A
Store secrets in ConfigMaps for easy retrieval.
Why wrong: Secrets should be stored in Kubernetes Secrets, not ConfigMaps, and encrypted at rest.
- B
Define Network Policies to isolate pods and control traffic flow.
Network policies enforce micro-segmentation and limit lateral movement.
- C
Disable RBAC to simplify management and reduce overhead.
Why wrong: Disabling RBAC removes access control, making the cluster vulnerable to unauthorized actions.
- D
Use default service accounts for all pods to avoid misconfiguration.
Why wrong: Default service accounts often have excessive permissions; custom accounts with least privilege are recommended.
- E
Implement Pod Security Policies to restrict privileged containers.
PSPs prevent containers from running with unnecessary privileges.
Quick Answer
The correct answers are Pod Security Policies to restrict privileged containers and Network Policies for pod-level traffic control. Pod Security Policies are a cluster-level security mechanism that enforces constraints on pod specifications, such as preventing the use of privileged containers, which is a fundamental Kubernetes security consideration to limit container breakout risks. Network Policies act as a software-defined firewall at the pod level, using label and namespace selectors to control ingress and egress traffic, enabling micro-segmentation to prevent lateral threat movement in a Cisco Intersight-managed cluster. On the Cisco DevNet Associate 200-901 exam, this question tests your understanding of native Kubernetes security controls versus external tools, with a common trap being to confuse RBAC or secrets management with pod-level security. Remember the mnemonic “Pods Protect, Networks Filter” to pair Pod Security Policies with Network Policies as the two direct Kubernetes security considerations.
200-901 Application Deployment and Security Practice Question
This 200-901 practice question tests your understanding of application deployment and security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 TWO of the following are valid security considerations when deploying an application to a Kubernetes cluster managed by Cisco Intersight? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Define Network Policies to isolate pods and control traffic flow.
Option B is correct because Network Policies in Kubernetes act as a firewall at the pod level, using label selectors and namespace selectors to control ingress and egress traffic. In a Cisco Intersight-managed cluster, defining these policies is a critical security consideration to enforce micro-segmentation and prevent lateral movement of threats. Option E is correct because Pod Security Policies (PSPs) are a cluster-level resource that control security-sensitive aspects of pod specification, such as preventing privileged containers, which is a key security best practice in Kubernetes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that ConfigMaps are suitable for secrets (they are not) and that disabling RBAC simplifies management (it actually creates a massive security hole), while candidates may overlook that Network Policies require a compatible CNI plugin to be effective.
Detailed technical explanation
How to think about this question
Network Policies are implemented by a CNI plugin (e.g., Calico, Cilium) that programs iptables or eBPF rules at the node level; without a compatible CNI, policies are not enforced. Pod Security Policies have been deprecated in Kubernetes 1.21 and removed in 1.25, replaced by Pod Security Admission (PSA) with predefined levels (privileged, baseline, restricted) — Cisco Intersight-managed clusters may still use PSPs or PSA depending on the version, so understanding the transition is important for exam scenarios.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
