D415 Software Defined Networking - Set 4 - Part 2

Correct Answer: Controller diversity

Controller diversity minimizes the risk of network attacks by distributing traffic across multiple controllers, preventing any single controller from becoming a bottleneck or point of failure.

Correct Answer: Heat

Heat is the OpenStack service for orchestrating cloud resources and applications, allowing users to deploy and manage resources using predefined templates.

Correct Answer: East/Westbound API

The East/Westbound API manages communication between groups of SDN controllers, ensuring that controllers are synchronized and traffic is distributed across the network.

Correct Answer: Sahara

Sahara is the OpenStack module responsible for provisioning and managing big data services such as Hadoop clusters, enabling scalable data processing in the cloud.

Correct Answer: Redundancy

Redundancy ensures that key network components are replicated across multiple locations, maintaining network availability even if some components fail.

Correct Answer: Manila

Manila is the OpenStack module responsible for managing shared file systems, allowing virtual machines to access shared storage across compute instances.

Correct Answer: Shuffling

Shuffling dynamically rearranges the network configuration in response to attacks, helping to protect the network from further exploitation.

Correct Answer: Trove

Trove is the OpenStack service that provides database-as-a-service (DBaaS), enabling users to deploy and manage relational and non-relational databases.

Correct Answer: Dynamic device association

Dynamic device association involves adjusting how network devices are linked to controllers, improving both network performance and security in SDN environments.

Correct Answer: Swift

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

Correct Answer: Controller diversity

Controller diversity distributes network traffic across multiple controllers, preventing overloading of any single controller and improving overall network resilience.

Correct Answer: Glance

Glance is responsible for managing virtual machine images in OpenStack, enabling users to store, catalog, and retrieve VM images for deployment.

Correct Answer: Northbound API

The northbound API manages communication between the SDN controller and external applications, allowing applications to request network services and influence the behavior of the network.

Correct Answer: Sahara

Sahara is the OpenStack module that provides big data services, allowing users to provision and manage Hadoop clusters and other big data processing frameworks.

Correct Answer: Controller-Switch trust

Controller-Switch trust ensures secure communication between SDN controllers and network devices, preventing unauthorized flow insertion by malicious entities.

Correct Answer: Heat

Heat is the OpenStack service that allows users to manage and orchestrate cloud applications and resources by using predefined templates.

Correct Answer: Shuffling

Shuffling helps defend against network attacks by dynamically reallocating resources such as IP addresses, paths, or system configurations, making it difficult for attackers to target the network.

Correct Answer: Swift

Swift is the OpenStack service responsible for providing object storage, allowing users to store and retrieve large amounts of unstructured data like media files or backups.

Correct Answer: Southbound API

The southbound API manages communication between the control plane and network devices, enabling the SDN controller to issue forwarding instructions to switches and routers.

Correct Answer: Horizon

Horizon provides a graphical user interface (GUI) that allows users to manage OpenStack services, including compute, storage, and network resources, making it easier to interact with the cloud.
