Question 3

Which of the following statements is true concerning the use of microVMs over user-space kernel implementations for advanced container sandboxing?

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

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

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

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

Question 4

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?

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

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

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

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

Question 5

Which of the following statements on static Pods is true?

AThe kubelet can run static Pods that span multiple nodes, provided that it has the necessary privileges from the API server.

BThe kubelet can run a maximum of 5 static Pods on each node.

CThe kubelet schedules static Pods local to its node without going through the kube-scheduler, making tracking and managing them difficult.

DThe kubelet only deploys static Pods when the kube-scheduler is unresponsive.
