Question 1

A container orchestration tool is needed to manage containers in a company's cloud environment. Which tool should be used to facilitate scalable container management?

Correct Answer: Kubernetes

The correct answer is Kubernetes. Kubernetes is a container orchestration tool that automates the deployment, scaling, and management of containerized applications, which is exactly what the question asked for. On the other hand, Hyper-V, vSphere, and Proxmox VE are not right answers because these are hypervisors, not container orchestration tools used for managing containers in cloud environments. Hyper-V and vSphere are used for creating and managing virtual machines, while Proxmox VE can be used to manage both virtual machines and containers, but it does not provide container orchestration. Therefore, Kubernetes is the right tool to use for scalable container management in a company's cloud environment.

Question 2

You have implemented a new cloud service at your company. After managing to connect to the provider's network, you are unable to access any resources via the provided APIs. Which firewall policy change could resolve this issue?

Correct Answer: Allow required API ports

The best answer is to 'Allow required API ports'. If you can't access services via the provider's API, it could be that the ports the API needs to use are not allowed through the firewall. By allowing the required ports, the firewall will let traffic through to those services. The other answers are incorrect because 'Enable ICMP redirect' would not have any effect on API access, 'Block unnecessary IP addresses' could potentially block more access rather than enable it, and 'Enable IPv6 support on all devices' would not affect ability to access a specific API, unless the API specifically required IPv6, which is not indicated in the question.

Question 3

For an organization using cloud services, you're asked to apply a change control policy to allow and implement modifications to the cloud environment. As a network administrator, which document should you refer to for the required information?

Correct Answer: Service Level Agreement (SLA)

The correct answer is 'Service Level Agreement (SLA)'. This is the document which defines the level of service expected by a customer from a supplier, laying out the metrics by which that service is measured, as well as remedies or penalties should agreed-upon service levels not be achieved. It is considered a critical component of any outsourcing contract, and should therefore contain details about changes in the cloud environment. The other options are not correct because: 'End-User License Agreement (EULA)' is a legal contract between the software application author/ publisher and the users of that software, 'Memorandum of Understanding (MOU)' is a document that describes the broad outlines of an agreement that two or more parties have reached, while 'Request for Proposal (RFP)' is a business document that announces a project, outlines its requirements, and asks for proposals from qualified vendors.
