Linux Foundation Kubernetes and Cloud Native Security Associate 認定 KCSA 試験問題 (Q11-Q16):

質問 # 11
A cluster administrator wants to enforce the use of a different container runtime depending on the application a workload belongs to.

正解：B

解説：
* Kubernetes supports workload-specific runtimes viaRuntimeClass.
* Amutating admission controllercan enforce this automatically by:
* Intercepting workload creation requests.
* Modifying the Pod spec to set runtimeClassName based on labels or policies.
* Incorrect options:
* (A) Manual modification is not scalable or secure.
* (B) kube-apiserver cannot enforce per-application runtime policies.
* (C) A validating webhook can onlyreject, not modify, the runtime.

CNCF Security Whitepaper - Admission controllers for enforcing runtime policies.


質問 # 12
An attacker has access to the network segment that the cluster is on.
What happens when a compromised Pod attempts to connect to the API server?

正解：D

解説：
* By default,Pods can connect to the API server(since ServiceAccount tokens are mounted).
* However, whether they succeed in acting depends on:
* Network Policies(may block egress).
* RBAC(controls permissions).
* Exact extract (Kubernetes Docs - API Access):
* "Pods authenticate to the API server using the service account token mounted into the Pod.
Authorization is then enforced by RBAC. NetworkPolicies may further restrict access."
* Clarifications:
* A: No default automatic isolation.
* B: Not always unrestricted; policies may apply.
* D: Pods get minimal default privileges, not automatic elevation.

質問 # 13
In order to reduce the attack surface of the Scheduler, which default parameter should be set to false?

正解：C

解説：
* Thekube-schedulerexposes aprofiling/debugging endpointwhen --profiling=true (default).
* This can unnecessarily increase the attack surface.
* Best practice: set --profiling=false in production.
* Exact extract (Kubernetes Docs - kube-scheduler flags):
* "--profiling (default true): Enable profiling via web interface host:port/debug/pprof/."
* Why others are wrong:
* --scheduler-name: just identifies the scheduler, not a security risk.
* --secure-kubeconfig: not a valid flag.
* --bind-address: changing it limits exposure but is not the default risk parameter for profiling.

Kubernetes Docs - kube-scheduler options: https://kubernetes.io/docs/reference/command-line-tools- reference/kube-scheduler/


質問 # 14
Which information does a user need to verify a signed container image?

正解：D

解説：
* Container image signing (e.g., withcosign, Notary v2) uses asymmetric cryptography.
* Verification process:
* Retrieve theimage's digital signature.
* Validate the signature with thepublic keyof the signer.
* Exact extract (Sigstore Cosign Docs):
* "Verification of an image requires the signature and the signer's public key. The signature proves authenticity and integrity."
* Why others are wrong:
* A & B: The private key is only used by the signer, never shared.
* C: The hash alone cannot prove authenticity without the digital signature.
References:
Sigstore Cosign Docs: https://docs.sigstore.dev/cosign/overview


質問 # 15
Which label should be added to the Namespace to block any privileged Pods from being created in that Namespace?

正解：C

解説：
* KubernetesPod Security Admission (PSA)enforcesPod Security Standardsby applying labels on Namespaces.
* Exact extract (Kubernetes Docs - Pod Security Admission):
* "You can label a namespace with pod-security.kubernetes.io/enforce: baseline to enforce the Baseline policy."
* Thebaselineprofile explicitly disallowsprivileged podsand other unsafe features.
* Why others are wrong:
* A & D: These labels do not exist in Kubernetes.
* B: Setting privileged: true would allow privileged pods, not block them.
