COA Networking and Storage Configuration

Question 1

Which OpenStack component provides networking services?

Accepted Answer

Neutron

Answer

Neutron is the dedicated networking service in OpenStack, providing network connectivity for virtual machines. It enables the creation and management of virtual networks, subnets, routers, and firewalls, allowing instances to communicate with each other and with external networks.

Question 2

What is the purpose of a floating IP in OpenStack?

Accepted Answer

Enables external network access

Answer

A floating IP in OpenStack is a public IP address that can be dynamically associated with a virtual machine instance. It allows external traffic from the internet to reach the instance and enables the instance to initiate outbound connections to external networks, providing public accessibility.

Question 3

What is the role of Cinder in OpenStack?

Accepted Answer

Manages block storage volumes

Answer

Cinder is the block storage service in OpenStack, providing persistent storage volumes that can be attached to instances. These volumes function like traditional hard drives, offering durable storage for data that needs to persist independently of the instance's lifecycle.

Question 4

Which storage service is used for object storage in OpenStack?

Accepted Answer

Swift

Answer

Swift is OpenStack's highly scalable, fault-tolerant object storage service, designed for storing large amounts of unstructured data. It provides a RESTful API for storing and retrieving objects, making it suitable for backups, archives, and static web content, distinct from block or file storage.

Question 5

Which type of network in OpenStack allows VMs to communicate with external networks?

Accepted Answer

Provider network

Answer

A provider network in OpenStack is a physical network that is directly mapped into the OpenStack environment, often representing an existing data center network. It allows virtual machines to have direct connectivity to external networks, enabling communication with resources outside the OpenStack cloud.
