NEW QUESTION 36
When using a cloud provider’s managed Kubernetes service, who is responsible for maintaining the etcd cluster?

Kubernetes administrator

Namespace administrator

Cloud provider

Application developer

NEW QUESTION 37
An attacker has successfully overwhelmed the Kubernetes API server in a cluster with a single control plane node by flooding it with requests.
How would implementing a high-availability mode with multiple control plane nodes mitigate this attack?

By implementing network segmentation to isolate the API server from the rest of the cluster, preventing the attack from spreading.

By distributing the workload across multiple API servers, reducing the load on each server.

By increasing the resources allocated to the API server, allowing it to handle a higher volume of requests.

By implementing rate limiting and throttling mechanisms on the API server to restrict the number of requests allowed.

NEW QUESTION 38
What kind of organization would need to be compliant with PCI DSS?

Retail stores that only accept cash payments.

Government agencies that collect personally identifiable information.

Non-profit organizations that handle sensitive customer data.

Merchants that process credit card payments.

NEW QUESTION 39
Which of the following statements best describe container image signing and verification in the cloud environment?

Container image signatures and their verification ensure their authenticity and integrity against tampering.

Container image signatures are concerned with defining developer ownership of applications within multi-tenant environments.

Container image signatures are mandatory in cloud environments, as cloud providers would deny the execution of unsigned container images.

Container image signatures affect the performance of containerized applications, as they increase the size of images with additional metadata.

NEW QUESTION 40
A cluster administrator wants to enforce the use of a different container runtime depending on the application a workload belongs to.

By manually modifying the container runtime for each workload after it has been created.

By modifying the kube-apiserver configuration file to specify the desired container runtime for each application.

By configuring avalidating admission controllerwebhook that verifies the container runtime based on the application label and rejects requests that do not comply.

By configuring amutating admission controllerwebhook that intercepts new workload creation requests and modifies the container runtime based on the application label.

NEW QUESTION 41
Is it possible to restrict permissions so that a controller can only change the image of a deployment (without changing anything else about it, e.g., environment variables, commands, replicas, secrets)?

Yes, by granting permission to the /image subresource.

Not with RBAC, but it is possible with an admission webhook.

No, because granting access to the spec.containers.image field always grants access to the rest of the spec object.

Yes, with a ‘managed fields’ annotation.

NEW QUESTION 42
Why does the defaultbase64 encodingthat Kubernetes applies to the contents of Secret resources provide inadequate protection?

Base64 encoding is vulnerable to brute-force attacks.

Base64 encoding relies on a shared key which can be easily compromised.

Base64 encoding does not encrypt the contents of the Secret, only obfuscates it.

Base64 encoding is not supported by all Secret Stores.

NEW QUESTION 43
In order to reduce the attack surface of the Scheduler, which default parameter should be set to false?

–scheduler-name

–profiling

–secure-kubeconfig

–bind-address

NEW QUESTION 44
Which of the following statements is true concerning the use ofmicroVMsover user-space kernel implementations for advanced container sandboxing?

MicroVMs allow for easier container management and orchestration than user-space kernel implementation.

MicroVMs offer higher isolation than user-space kernel implementations at the cost of a higher per- instance memory footprint.

MicroVMs provide reduced application compatibility and higher per-system call overhead than user- space kernel implementations.

MicroVMs offer lower isolation and security compared to user-space kernel implementations.

NEW QUESTION 45
A cluster is failing to pull more recent versions of images from k8s.gcr.io. Why may this be?

There is a network connectivity issue between the cluster and k8s.gcr.io.

There is a bug in the container runtime or the image pull process.

The authentication credentials for accessing k8s.gcr.io are incorrectly scoped.

The container image registry k8s.gcr.io has been deprecated.

NEW QUESTION 46
Which of the following statements regarding a container run with privileged: true is correct?

A container run with privileged: true within a cluster can access all Secrets used within that cluster.

A container run with privileged: true within a Namespace can access all Secrets used within that Namespace.

A container run with privileged: true on a node can access all Secrets used on that node.

A container run with privileged: true has no additional access to Secrets than if it were run with privileged: false.

NEW QUESTION 47
In a Kubernetes cluster, what are the security risks associated with using ConfigMaps for storing secrets?

Storing secrets in ConfigMaps does not allow for fine-grained access control via RBAC.

Storing secrets in ConfigMaps can expose sensitive information as they are stored in plaintext and can be accessed by unauthorized users.

Using ConfigMaps for storing secrets might make applications incompatible with the Kubernetes cluster.

ConfigMaps store sensitive information in etcd encoded in base64 format automatically, which does not ensure confidentiality of data.

NEW QUESTION 48
What was the name of the precursor to Pod Security Standards?

Container Runtime Security

Kubernetes Security Context

Container Security Standards

Pod Security Policy

NEW QUESTION 49
Given a standard Kubernetes cluster architecture comprising a single control plane node (hosting bothetcdand the control plane as Pods) and three worker nodes, which of the following data flows crosses atrust boundary
?

From kubelet to Container Runtime

From kubelet to API Server

From kubelet to Controller Manager

From API Server to Container Runtime

NEW QUESTION 50
Which of the following statements correctly describes a container breakout?

A container breakout is the process of escaping the container and gaining access to the Pod’s network traffic.

A container breakout is the process of escaping a container when it reaches its resource limits.

A container breakout is the process of escaping the container and gaining access to the cloud provider’s infrastructure.

A container breakout is the process of escaping the container and gaining access to the host operating system.

NEW QUESTION 51
In which order are thevalidating and mutating admission controllersrun while the Kubernetes API server processes a request?

The order of execution varies and is determined by the cluster configuration.

Validating admission controllers run before mutating admission controllers.

Validating and mutating admission controllers run simultaneously.

Mutating admission controllers run before validating admission controllers.

Enabling Admission Controllers to validate image signatures.

Using PodSecurityPolicy (PSP) to enforce image signing and validation.

Using Pod Security Standards (PSS) to enforce validation of signatures.

Configuring Container Runtime Interface (CRI) to enforce image signing and validation.

NEW QUESTION 53
What information is stored in etcd?

Etcd manages the configuration data, state data, and metadata for Kubernetes.

Application logs and monitoring data for auditing and troubleshooting purposes.

Sensitive user data such as usernames and passwords.

Pod data contained in Persistent Volume Claims (e.g. hostPath).

NEW QUESTION 54
Which technology can be used to apply security policy for internal cluster traffic at the application layer of the network?

By setting the container runtime as an environment variable in the Pod.

By specifying the container runtime in the Pod’s YAML file.

NEW QUESTION 56
A Kubernetes cluster tenant can launch privileged Pods in contravention of therestricted Pod Security Standardmandated for cluster tenants and enforced by the built-inPodSecurity admission controller.
The tenant has full CRUD permissions on the namespace object and the namespaced resources. How did the tenant achieve this?

The scope of the tenant role means privilege escalation is impossible.

By tampering with the namespace labels.

By deleting the PodSecurity admission controller deployment running in their namespace.

By using higher-level access credentials obtained reading secrets from another namespace.
