Which of the following network interface types are valid in an LXD container configuration? (Choose THREE)
LXD supports several network interface types that define how containers connect to the host and external networks. According to LXD documentation, valid interface types include physical, bridged, and macvlan.
A physical interface allows a container to be directly connected to a host network interface. A bridged interface connects the container to a Linux bridge, enabling communication with other containers and external networks. Macvlan assigns a unique MAC address to the container, making it appear as a separate device on the physical network.
Options wif and ipsec are not valid LXD network interface types. Therefore, the correct answers are C, D, and E.
Which file in a cgroup directory contains the list of processes belonging to this cgroup?
The file procs in a cgroup directory contains the list of processes belonging to this cgroup. Each line in the file shows the PID of a process that is a member of the cgroup. A process can be moved to a cgroup by writing its PID into the cgroup's procs file. For example, to move the process with PID 24982 to the cgroup cg1, the following command can be used: echo 24982 > /sys/fs/cgroup/cg1/procs1. The file procs is different from the file tasks, which lists the threads belonging to the cgroup. The file procs can be used to move all threads in a thread group at once, while the file tasks can be used to move individual threads2. Reference:

Which of the following is true about LXC?
LXC (Linux Containers) is a container runtime that uses Linux kernel features such as namespaces and cgroups to provide lightweight, isolated environments. According to containerization documentation, LXC allows multiple Linux systems (containers) to run on a single host while sharing the same kernel.
LXC is Linux-specific, uses the Linux kernel directly, and is not a virtual machine manager. Therefore, the correct answer is C.
Which of the following statements are true regarding IaaS computing instances? (Choose TWO correct answers.)
Infrastructure as a Service (IaaS) provides on-demand virtual computing resources that can be dynamically created and destroyed. According to cloud computing documentation, IaaS instances are designed to be ephemeral, allowing users to launch instances when needed and terminate them when no longer required. This makes statement A correct.
Additionally, IaaS platforms expose APIs and service interfaces that enable full automation of instance lifecycle management. Instances can be created, modified, and deleted programmatically using scripts, orchestration tools, or cloud SDKs, making statement B correct.
Statement C is incorrect because root disks are often ephemeral unless explicitly configured as persistent volumes. Statement D contradicts the elastic nature of IaaS, and statement E is false because users may have zero, one, or many instances.
Therefore, the correct answers are A and B.
What is the purpose of the kubelet service in Kubernetes?
The purpose of the kubelet service in Kubernetes is to run containers on the worker nodes according to the Kubernetes configuration. The kubelet is an agent or program that runs on each node and communicates with the Kubernetes control plane. It receives a set of PodSpecs that describe the desired state of the pods that should be running on the node, and ensures that the containers described in those PodSpecs are running and healthy. The kubelet also reports the status of the node and the pods back to the control plane. The kubelet does not manage containers that were not created by Kubernetes. Reference:
