d415 Software Defined Networking - Set 5 - Part 1

Correct Answer: Heat

Heat allows users to orchestrate cloud applications by defining them as a collection of resources, such as servers, networks, and storage, which can be managed using templates.

Correct Answer: Control plane

The control plane in SDN is responsible for managing network control functions like routing, traffic engineering, and policy enforcement.

Correct Answer: Neutron

Neutron is the OpenStack module that provides networking as a service (NaaS), enabling virtual machines and other resources to communicate with each other.

Correct Answer: Fine-grained data flow management

Fine-grained data flow management enforces strict data flow policies to prevent unauthorized traffic from moving through the network, increasing security.

Correct Answer: Cinder

Cinder provides persistent block storage to virtual machines, allowing data to remain available even after instances are stopped or terminated.

Correct Answer: Data plane

The data plane is responsible for physically forwarding data packets from one node to another within the SDN network.

Correct Answer: Barbican

Barbican provides key management services in OpenStack, allowing users to securely manage encryption keys, digital certificates, and other sensitive data.

Correct Answer: SDN controller

The SDN controller provides a centralized view of the entire network, enabling network automation, optimization, and efficient management of resources.

Correct Answer: Trove

Trove provides database management services, allowing users to deploy and manage both relational and non-relational databases within an OpenStack environment.

Correct Answer: Controller-Switch trust

Controller-Switch trust ensures secure communication between the controller and network devices by preventing unauthorized flows from being inserted into the network.

Correct Answer: Swift

Swift provides object storage services, allowing users to store and retrieve large amounts of unstructured data such as backups or media files.

Correct Answer: East/Westbound API

The East/Westbound API allows communication between SDN controllers, ensuring synchronization and load distribution across the network.

Correct Answer: Horizon

Horizon is the OpenStack service that provides a graphical user interface (GUI) for managing and interacting with OpenStack resources and services.

Correct Answer: Replication

Replication ensures high availability by creating multiple copies of key network components, ensuring services remain available even if some components fail.

Correct Answer: Sahara

Sahara is the OpenStack service that allows users to deploy, scale, and manage Hadoop clusters and other big data processing frameworks.

Correct Answer: Dynamic device association

Dynamic device association ensures that network devices are dynamically connected to the correct controllers, improving fault tolerance and security.

Correct Answer: Keystone

Keystone handles authentication and access control in OpenStack, ensuring that only authorized users can access specific OpenStack services.

Correct Answer: Control plane

The control plane in SDN manages how network traffic is handled, providing centralized intelligence to make routing, traffic engineering, and policy decisions.

Correct Answer: Cinder

Cinder provides block storage services for OpenStack, enabling persistent data storage for virtual machines, even after they are stopped or terminated.

Correct Answer: Northbound API

The Northbound API allows external applications to communicate with the SDN controller, enabling real-time changes to network configurations and behaviors.
