NEW QUESTION # 103
Which cloud management tools are known for their infrastructure-as-code (IaC) approach? (Select all that apply)
Answer: A,B,C,D
Explanation:
Infrastructure as Code (IaC) is an approach where infrastructure is defined and managed usingmachine- readable configuration files. According to DevOps and cloud documentation,Puppet, Terraform, AWS CloudFormation, and Ansibleall support IaC principles.
Terraform and AWS CloudFormation are declarative IaC tools used to provision cloud infrastructure. Puppet and Ansible are configuration management and automation tools that also enable infrastructure definition through code.
All listed tools are widely recognized in IaC workflows, makingA, B, C, and Dcorrect.
NEW QUESTION # 104
When using Packer to create machine images, what are some common sources for base images? (Select all that apply)
Answer: B,D
Explanation:
Packer is an image automation tool used to create identical machine images for multiple platforms from a single configuration. According to virtualization and containerization documentation, Packer typically uses trusted and standardized base imagesas the starting point for image creation. The most common sources includeofficial operating system imagesprovided by vendors such as Red Hat, Ubuntu, or cloud service providers, andcustom images created internally by an organization.
Using official images ensures that the base system is secure, properly maintained, and compliant with vendor standards. Organizations often build custom base images to enforce internal security policies, hardening standards, and preinstalled software, which Packer then extends into environment-specific images.
Physical servers are not considered common or practical base sources for Packer, as Packer operates on machine image artifacts rather than cloning live hardware systems. Images from untrusted sources are explicitly discouraged in virtualization documentation due to security and compliance risks.
Therefore, documentation clearly supportscustom organizational imagesandofficial operating system imagesas the correct and recommended base sources for Packer image creation.
NEW QUESTION # 105
What is the typical format for cloud-init configuration files?
Answer: D
Explanation:
Cloud-init configuration files are typically written inYAML (Yet Another Markup Language)format.
Official cloud-init documentation specifies thatcloud-configfiles use YAML syntax, which is human-readable and well suited for declarative configuration.
YAML files allow administrators to define users, packages, services, networking, and commands in a structured and consistent way. While cloud-init can process shell scripts and MIME multipart data, YAML remains thestandard and recommended format.
Thus, the correct answer isD.
NEW QUESTION # 106
Which of the following statements are true regarding a Pod in Kubernetes? (Choose two.)
Answer: A,D
Explanation:
A Pod in Kubernetes is a collection of one or more containers that share the same network and storage resources, and a specification for how to run the containers. A Pod is the smallest unit of workload Kubernetes can run, meaning that it cannot be divided into smaller units. Therefore, option C is correct. All containers of a Pod run on the same node, which is the smallest unit of computing hardware in Kubernetes. A node is a physical or virtual machine that hosts one or more Pods. Therefore, option A is also correct. Pods are not always created automatically and cannot be explicitly configured. Pods can be created manually using YAML or JSON files, or using commands like kubectl run or kubectl create. Pods can also be created automatically by higher-level controllers, such as Deployment, ReplicaSet, or StatefulSet. Therefore, option B is incorrect. When a Pod fails, Kubernetes does not restart the Pod on another node by default. Pods are ephemeral by nature, meaning that they can be terminated or deleted at any time. If a Pod is managed by a controller, the controller will create a new Pod to replace the failed one, but it may not be on the same node.
Therefore, option D is incorrect. systemd is not used to manage individual Pods on the Kubernetes nodes.
systemd is a system and service manager for Linux operating systems that can start and stop services, such as docker or kubelet. However, systemd does not interact with Pods directly. Pods are managed by the kubelet service, which is an agent that runs on each node and communicates with the Kubernetes control plane.
Therefore, option E is incorrect. References:

* What is a Kubernetes pod? - Red Hat
* What's the difference between a pod, a cluster, and a container?
